Executive Snapshot and Market Trajectory

Autonomous coding reaches roughly 71% direct-to-bill rates in radiology and pathology and performs poorly on narrative charts requiring sequencing judgement. It is taking the cheap volume and leaving the expensive residue, which raises average cost per remaining chart rather than reducing it. Fewer people remain qualified to do that work.
North America takes 42% of value, well above the standard band, because coding exists as a distinct commercial industry chiefly on account of American code-based fee-for-service payment. India grows fastest at 11.1% and delivers roughly 38% of American coding work, which makes it simultaneously the fastest growing market and the largest offshore delivery base for another one. Data protection and licensure overhead partly offsets the labour arbitrage available there.
Concentration is very low at 24% and the binding constraint is demographic rather than technological. Certified coders are leaving the workforce faster than replacements qualify, with roughly 18% of posted positions unfilled beyond three months. That shortage drove offshoring and automation, not the other way round. Technology followed the labour problem rather than creating it, which is the opposite of how this story is usually told anywhere. The shortage came first. Nobody designed this.

USA Medical Coding Market Forecast Scenarios

usa-medical-coding-market-size-forecast-scenario-1787702385397
Growth from 2020 to 2025 ran at 8.0% and labour shortage rather than volume drove much of it. Certified coder vacancies persisted throughout, which pushed providers toward offshore delivery and toward automation in whichever specialties would support it. Risk adjustment coding expanded rapidly with Medicare Advantage enrolment and then attracted intense regulatory scrutiny, which changed the commercial risk profile of that whole service line within about two years.
The 9.0% base case rests on three mechanisms. Autonomous coding keeps clearing structured specialties, which shifts human effort toward complex charts that cost considerably more per unit to process. Audit and compliance review keeps expanding because repayment exposure has become a board-level concern rather than an operational one. And offshore delivery capacity keeps growing faster than domestic training pipelines replace retiring coders. None of the three depends on encounter volume rising.
The bull case at 10.2% assumes audit intensity continues rising and providers invest heavily in pre-submission review rather than accepting repayment risk. The bear case at 7.8% is autonomous coding extending successfully into complex inpatient work, which would remove a large block of human coding volume without any corresponding growth elsewhere in the market to replace it.

The Charts Machines Cannot Read

This industry exists because payment and clinical documentation use different languages. A clinician writes what happened; a coder converts it into standardised codes; a payer pays on the code rather than on the note. Everything commercially interesting here sits in that translation gap, and the gap is not closing. Automation has changed who does the translating in some specialties without changing the fact that translation remains necessary at all.

Autonomous coding works where reports are structured and code sets repeat, reaching roughly 71% direct-to-bill rates in radiology, pathology and ophthalmology. It works considerably less well on emergency medicine and inpatient charts, where narrative documentation, sequencing decisions and clinical judgement determine the correct code. Machines take the cheap charts and humans keep the expensive ones.
The constraint underneath all of it is demographic. Certified coders are leaving the workforce faster than new ones qualify, and roughly 18% of posted positions remain unfilled beyond three months. That shortage is what drove offshore delivery to India and the Philippines and what made automation commercially attractive in the first place. Technology followed the labour problem rather than creating it.

Market Trends

Autonomous Coding Clears Structured Specialties And Stops

Direct-to-bill rates reach roughly 71% in radiology, pathology and ophthalmology where reports are structured and code sets repeat predictably. Emergency medicine and inpatient work resist automation because narrative documentation and sequencing judgement determine the correct code rather than any pattern in the text. Growth at 13.5% therefore concentrates in a bounded set of specialties. Providers modelling automation as general cost reduction discover instead that they have reallocated cost toward the charts that were always the most expensive. The residue is more expensive than the automated volume ever was, and there are fewer people qualified to handle it.
Market Impact: Leaves 18% of positions unfilled

Audit Exposure Moved From Operational To Board Level

Roughly 6.4% of reviewed claims require adjustment after compliance review, and risk adjustment coding in particular attracted intense regulatory scrutiny that changed how boards view the whole activity. Undercoding loses revenue quietly while overcoding creates repayment liability and litigation exposure, which is a genuinely asymmetric risk. Growth at 8.4% in audit and compliance review follows that shift directly, and pre-submission review is increasingly preferred to discovering problems after payment has already been received. Providers now fund verification deliberately rather than treating audit as an overhead they tolerate. Boards ask about it now.
Market Impact: Delivers 38% of American work

Market Opportunities and Growth Drivers

Coder Shortage Drives Offshore And Automated Delivery

Certified coders are leaving the workforce faster than the credentialing pipeline replaces them, and roughly 18% of posted positions stay unfilled beyond three months, which is a demographic problem no technology decision created. Providers responded by moving work offshore and by automating whatever specialties would support it. India delivers roughly 38% of American coding work as a direct consequence. Domestic training capacity has not expanded anywhere near enough to change that trajectory meaningfully. Complex charts remain entirely dependent on credentialed human judgement whatever happens elsewhere. Training capacity has not expanded nearly enough.
Market Impact: Automates the cheapest 71%

Indian Delivery Capacity Grows Faster Than Any Market

India grows fastest of any country at 11.1%, and it does so in two ways at once, expanding both its domestic healthcare administration market and its share of American coding work delivered offshore. Roughly 38% of that work is already performed there. Data protection obligations and credentialing requirements add overhead that partly offsets the labour cost advantage, which is why offshoring has not gone further than it has despite the arbitrage available. Training and credentialing capacity has expanded substantially around that work over the past decade. Arbitrage is narrower than it appears.
Market Impact: Penalises 1 error direction heavily

Market Restraints and Challenges

Automation Raises Average Cost Per Remaining Chart

Autonomous coding clears the structured specialties at roughly 71% direct-to-bill rates and leaves human coders the narrative charts that always cost most to process. Root cause is that automation succeeds precisely where judgement is least required, which is also where cost was lowest. The commercial impact is providers projecting cost reduction and finding cost reallocation instead, with a smaller workforce handling harder work. Mitigation involves modelling blended cost honestly rather than counting automated charts alone. Fewer people remain qualified to handle it. Blended cost modelling is the honest answer. Optimism costs margin.
Market Impact: Reaches 71% in structured specialties

Asymmetric Audit Risk Punishes Errors Unequally

Undercoding loses revenue silently and creates no liability, while overcoding produces repayment obligations and litigation exposure that reach board attention quickly. Root cause is a regulatory structure that treats the two error directions very differently. The commercial impact is systematic conservatism that costs providers legitimate revenue, and roughly 6.4% of reviewed claims still require adjustment. Mitigation runs through pre-submission audit rather than post-payment correction, which more providers now fund deliberately. Conservatism costs legitimate revenue quietly, and nobody measures that loss anywhere in the organisation. Pre-submission review addresses both directions. Boards fund it now.

Segment CAGR and Growth Architecture

Segmentation follows the coding work performed: what is being coded or reviewed and by what method, rather than which provider organisation buys it or where it is delivered. Six work categories cover the market without overlap. Delivery location and contracting model are treated as separate commercial dimensions throughout this report. Chart complexity cuts across every one of these categories.
usa-medical-coding-market-market-share-analysis-1787702385570

Autonomous and Computer-Assisted Coding

Growth at 13.5%, half again the market rate of 9.0%, concentrates in radiology, pathology and ophthalmology where structured reports and repeating code sets support direct-to-bill rates around 71%. Emergency medicine and inpatient coding resist automation because narrative documentation and sequencing judgement determine the correct code rather than any pattern a model can reliably learn. Providers modelling this as general cost reduction find cost reallocation instead, since the charts left behind are precisely the ones that always cost most to process. Fewer credentialed people remain available to process that residue, which compounds the problem considerably. Automation succeeded exactly where judgement mattered least, which is also where the cost per chart was already lowest anywhere.
CAGR 13.5%

Risk Adjustment and HCC Coding

Risk adjustment coding expanded rapidly with Medicare Advantage enrolment and then attracted intense regulatory scrutiny that changed the commercial risk profile of the whole service line within roughly two years. Growth at 10.2% continues because the coding remains necessary and the scrutiny made accuracy considerably more valuable than volume. Providers now fund pre-submission review rather than accepting repayment exposure after the fact, which shifts spending from throughput toward verification and rewards a quite different kind of capability. Accuracy has become worth more than throughput, which rewards a different capability from the one most providers built. Verification rather than throughput is what providers now fund, and the buyer inside the organisation has changed accordingly.

Regional Architecture and Country Demand Map

Geography follows payment structure and delivery capacity rather than healthcare volume, since coding exists as a commercial industry chiefly under American billing rules. North America dominates demand and India dominates offshore delivery. Two regions sit outside the standard share bands for that same reason, and both are flagged here.

North America

The 42% share sits far above the standard band because code-based fee-for-service payment created a distinct commercial coding industry that has no direct equivalent under capitated or budget-funded systems. Certified coder vacancies persist at roughly 18% beyond three months, which drove both offshore delivery and automation adoption. Risk adjustment scrutiny changed how boards regard coding accuracy, moving spending toward pre-submission audit. Autonomous coding adoption is furthest advanced here, concentrated in the structured specialties where it genuinely works well. Complex specialty coding and audit capability are where remaining value concentrates, since structured volume is being cleared by software that improves every year. Boards now treat coding accuracy as a governance question rather than an operational metric.
Share: 42% | CAGR: 8.2% (2026 to 2036)

Western Europe

Coding supports casemix funding and activity monitoring rather than claim-by-claim payment, which makes it a hospital administrative function rather than a large commercial services market. National classification systems differ between countries, so no pan-European service market has formed at any scale. Clinical coders are employed directly by hospitals in most systems. Automation is developing where structured reporting supports it, though the commercial incentive is weaker because coding accuracy affects budget allocation rather than immediate payment. Commercial coding services remain a small market relative to healthcare spending, and no equivalent of the American outsourcing industry has formed anywhere. Automation follows structured reporting adoption rather than any reimbursement incentive, which slows it considerably.

Pricing The Charts That Remain

Autonomous coding clears roughly 71% of structured specialty charts, about 18% of coder positions stay unfilled, some 6.4% of reviewed claims need adjustment, and India delivers 38% of American work. Four levers work on blended pricing, audit capability, training supply and specialty focus rather than on throughput. Throughput is no longer where value sits.

Price On Blended Cost Not Automated Volume

Automation clears roughly 71% of charts in structured specialties and leaves human coders the narrative work that always cost most, which means average cost per remaining chart rises rather than falls. Providers pricing contracts on automated throughput discover the residue is more expensive than the blended rate they agreed. Modelling the mix honestly at contract stage protects margin that optimistic automation assumptions destroy quietly across the whole term of an agreement. The difference compounds quietly across a whole contract term, and it is rarely visible until renewal comes round. Renewal exposes it.
Market Impact: Prices the 29% that requires genuine human judgement

Build Pre-Submission Audit Rather Than Correction

Roughly 6.4% of reviewed claims require adjustment, and undercoding loses revenue silently while overcoding creates repayment and litigation exposure that reaches board attention quickly. Pre-submission review addresses both directions before money moves, which post-payment correction cannot do at all. Providers now fund this deliberately rather than treating it as overhead. Service providers offering verification capability compete on a dimension throughput specialists have never built. Compliance officers fund accuracy where revenue cycle directors buy throughput, which means a different buyer entirely. Very few providers have made that call. Accuracy is now the product.
Market Impact: Corrects the 6.4% before any payment actually moves

Fund Credentialing Pipelines You Will Hire From

Certified coders leave the workforce faster than the pipeline replaces them and roughly 18% of posted positions stay unfilled beyond 3 months, which no automation decision fixes for the complex charts that matter most. Service providers funding training and credentialing build a labour supply competitors must bid against them for. It takes years and it addresses the only genuinely binding constraint in this industry rather than working around it. Recruitment from a shrinking pool is a bidding contest nobody wins. Building supply beats bidding for it, and the providers who started early are already several cohorts ahead of everybody else.
Market Impact: Addresses the 18% of unfilled credentialed coder positions

Specialise In Work Automation Will Not Reach

Emergency medicine, inpatient and complex surgical coding resist automation because narrative documentation and sequencing judgement determine the code rather than any learnable pattern. Providers building capability there hold work that will not be automated away, at rates reflecting genuine difficulty. Competitors chasing the structured specialties are competing directly against software that improves every year and prices toward zero. Specialising in difficulty is uncomfortable and considerably more durable. Roughly 29% of charts resist automation entirely, and that share is where credentialed judgement earns what it is genuinely worth rather than what a volume contract pays.
Market Impact: Holds the 29% of charts resisting automation entirely

Who Controls the Margin Pool

Measured on disclosed revenue cycle and health information management services revenue, the five largest providers hold a CR5 of just 24%, which reflects a fragmented services market where provider relationships are local and switching is operationally disruptive rather than technically difficult. Optum, R1 RCM and Ensemble hold substantial integrated revenue cycle positions, while AGS Health and Conifer carry large dedicated coding operations across American provider organisations. Local relationships matter more here than national scale ever has.
Three contests define activity. Volume coding services compete on price per chart and delivery capacity, increasingly from offshore locations. Autonomous coding technology competes on direct-to-bill rates within the specialties where it genuinely works. And audit and compliance review competes on accuracy capability and regulatory understanding, which is a professional services contest rather than a throughput one. A provider organised for one contest is rarely equipped for the others.

Pressure builds as automation takes structured volume while the remaining work grows more expensive and harder to staff. Rankings shift toward providers holding complex specialty capability and audit expertise. Anybody competing on price per chart in radiology is competing against software that improves annually. That is a losing position.

Competitive Moat and Risk Dimensions

OPTUM

Moat: Integrated Revenue Cycle Position

Optum delivers coding within a broader revenue cycle and payer relationship, which lets it price the activity against total revenue outcomes rather than against cost per chart alone. That integration is not available to a dedicated coding provider competing on unit price. A health system already using the wider platform faces meaningful disruption in separating coding out to somebody else.
OPTUM

Risk: Regulatory And Integration Scrutiny

Combining payer, provider services and revenue cycle assets attracts sustained regulatory attention, and risk adjustment coding in particular has drawn intense scrutiny across the sector. Integration advantages depend on arrangements that policy could restrict. An advantage resting on permitted combination is exposed to decisions made entirely elsewhere.
AGS HEALTH

Moat: Offshore Delivery And Credentialing Scale

AGS operates offshore coding delivery at a scale supported by its own credentialing and training capacity, which addresses the labour constraint rather than merely working around it. India already delivers roughly 38% of American coding work. Building comparable trained capacity takes years, and clients depend on continuity that smaller providers struggle to guarantee reliably.
AGS HEALTH

Risk: Automation Displacement Of Volume

Offshore delivery scale is most valuable in high-volume structured coding, which is precisely the work autonomous systems clear at roughly 71% direct-to-bill rates. Labour cost advantage competes against software that improves annually and prices toward zero. Scale in the automatable segment is an asset with a visible expiry attached to it.

Recent Developments

FEBRUARY 2025

Health system reports automation shifting cost rather than reducing it

A health system reported that autonomous coding had cleared a large share of structured specialty volume while total coding cost fell far less than projected, an operational disclosure rather than any corporate transaction. The charts remaining were the complex ones that always cost most to process.
Signal: Automation reallocates cost toward complex charts rather than removing it from the overall coding function. Savings disappoint.
JUNE 2025

Regulatory scrutiny reshapes risk adjustment coding service demand

Continued regulatory attention to risk adjustment coding accuracy moved provider spending toward pre-submission verification and away from throughput, a market shift driven by enforcement rather than by any corporate event. Repayment and litigation exposure had become a board-level concern across a number of large organisations.
Signal: Audit exposure moved coding accuracy from an operational metric to a governance question for provider boards.
OCTOBER 2025

Service provider funds domestic coder credentialing programme directly

A coding services provider funded credentialing and training places directly rather than recruiting from an already constrained pool, an organic investment rather than any acquisition. Roughly one in six posted coding positions had been remaining unfilled beyond three months across American provider organisations for several years.
Signal: Funding the credentialing pipeline addresses the only genuinely binding constraint in this industry. Nothing else fixes it.

What Coding Costs To Deliver

Labour dominates and everything else is comparatively minor, which is why delivery location matters so much here. Coder salaries, supervision and quality review account for 61 to 72% of service delivery cost in domestic operations and a smaller absolute figure offshore. Technology platforms, secure infrastructure and compliance overhead add the remainder. Autonomous coding inverts the structure entirely, replacing recurring labour with development cost amortised across processed volume.
The volatility that mattered was coder wage inflation together with data protection compliance cost. Certified coder wages rose sharply through 2022 and 2023 as vacancies persisted, which raised domestic delivery cost on contracts frequently priced years earlier. Offshore delivery carries data protection and licensure overhead that grew alongside, partly offsetting the labour arbitrage. Facility costs also rose, which IEA commercial energy price data records. Contracts priced years earlier absorbed it.

Exposure divides by delivery model rather than by scale. Domestic providers carry wage inflation on a constrained labour pool with no substitute available for complex work. Offshore providers carry compliance overhead alongside currency exposure. Technology-led providers carry development cost against volume that automation itself is making cheaper per unit. Every model here has a cost problem, and automation does not solve it.
usa-medical-coding-market-cost-volatility-analysis-1787702386114

Model residual chart complexity into contract pricing

Automation clears the structured specialties and leaves the narrative charts that always cost most to process, so blended rates agreed on projected automation levels understate what delivery will actually cost. Modelling the residue honestly at contract stage protects margin across the full term. Providers who priced on automated throughput alone have discovered the difference painfully over several years.

Fund credentialing rather than bidding for scarce coders

Certified coders leave the workforce faster than the pipeline replaces them and roughly one in six posted positions stays unfilled beyond three months, which makes recruitment a bidding contest nobody wins. Funding training and credentialing places builds supply rather than competing for it. It takes years and it addresses the binding constraint rather than working around it.

Weight capability toward specialties automation cannot reach

Emergency medicine, inpatient and complex surgical coding resist automation because judgement and sequencing rather than pattern determine the correct code. Capability there holds work that will not be automated away and prices according to genuine difficulty. Competing on price per chart in radiology means competing against software that improves every year and trends toward negligible marginal cost.

Portfolio Architecture for Margin Defence

Margin follows difficulty and regulatory exposure rather than volume, which inverts the usual services logic. High-volume outpatient coding earns thinly and is the most automatable work in the market. Inpatient and facility coding earns better on complexity. Risk adjustment coding earns well and carries regulatory exposure that has grown considerably. Audit and compliance review earns most, because accuracy verification is a professional judgement service rather than a throughput one entirely.
The tension is that scale was built for exactly the work that is disappearing. Offshore delivery capacity and process discipline were assembled to handle structured high-volume coding, which autonomous systems now clear at roughly 71% direct-to-bill rates in the relevant specialties. The capability that remains valuable is complex specialty judgement and audit expertise, which requires senior credentialed people rather than scaled delivery, and those are different businesses entirely.

High-value pools sit in three places. Complex specialty coding that automation cannot reach, priced on genuine difficulty. Pre-submission audit and compliance verification, where asymmetric regulatory risk makes accuracy worth paying for. And credentialing capacity, which addresses the binding labour constraint and creates supply competitors must bid against you to obtain.

Volume / Commodity-Adjacent

High-volume outpatient and professional fee coding delivered at scale, principally from offshore locations. The 9-point range is wide because domestic and offshore delivery carry entirely different labour cost bases despite competing for identical work at similar prices.
Gross Margin: 17-26%

Premium / Certified

Inpatient and facility coding together with risk adjustment work requiring credentialed judgement and regulatory understanding. The 10-point spread separates providers with senior credentialed capability from those staffing complex work with generalist coders under supervision.
Gross Margin: 31-41%

Sustainability / Regulatory / Next-Generation

Autonomous coding technology, audit and compliance verification, and coding education and credentialing services. The 26-point range is wide because software margins and professional services economics behave completely differently at scale.
Gross Margin: 38-64%
usa-medical-coding-market-portfolio-architecture-1787702386305

High-value Sub-segments and Strategic Watch-out

Audit And Compliance Verification

Highest margin and growing at 8.4%, because asymmetric regulatory risk makes pre-submission accuracy worth considerably more than throughput. The risk is that it requires senior credentialed judgement rather than scaled delivery, which is a fundamentally different business from volume coding services. Senior judgement is scarce.
Gross Margin: 56-64%

Autonomous Coding Technology

Fastest growth at 13.5% with software economics, clearing roughly 71% of charts in the structured specialties. The risk is that the addressable specialties are bounded, and extending into narrative inpatient work has proved considerably harder than early projections assumed. Narrative charts resist it. Progress there has been slow.
Gross Margin: 48-58%

High-Volume Outpatient Coding

The volume core, thin on margin and the most automatable work anywhere in this market. Providers hold it because it carries delivery scale and client relationships, and because losing it removes the account before higher value work can ever be introduced. Accounts start here always.
Gross Margin: 18-24%

The Residual Complex Chart

The strategic watch-out. Automation clears the cheap charts and leaves the expensive ones, which raises average cost per remaining chart against contracts priced on projected savings. The risk is that providers who priced on automated throughput carry that difference across whole contract terms. Renewal exposes it.
Gross Margin: 26-32%

Every Encounter Needs Translating

Demand is continuous and tracks clinical activity directly, since every encounter that generates a claim must be coded before anybody is paid for it. That produces reliable recurring volume tied to a provider's patient throughput rather than to any purchasing cycle. What varies is who performs the translation and at what cost, which is where all the movement happens.
Stickiness is operational rather than contractual. Switching coding providers means transferring workflow, retraining on local documentation practice and accepting a quality dip during transition, which health systems avoid unless something has gone genuinely wrong. Audit and compliance relationships are stickier still, since they involve regulatory judgement a provider organisation comes to depend on. Autonomous coding technology embedded in workflow is the stickiest of all once integrated.

The decision maker has moved upward as risk has grown. Volume coding is contracted by revenue cycle directors on price per chart and turnaround. Audit and compliance capability is increasingly selected with chief financial officer and compliance officer involvement, because repayment exposure reaches boards. Autonomous coding decisions involve clinical informatics and health information leadership together. Providers organised only for the first conversation are absent from the two that carry margin.

Where Difficulty Creates Value

These are among the four positions where our research anticipates prominent divergence between winners and laggards over the coming forecast period. Each is grounded in the demand model, the regulatory perimeter, and the announced capacity pipeline.
01 / BLENDED PRICING REALISM

You automated the cheap chart not the cost

Autonomous coding now clears roughly 71% of all charts in radiology, pathology and ophthalmology and performs poorly on narrative work where sequencing judgement determines the correct code. What remains for the human coders is precisely the material that always carried the highest processing cost of anything sitting in the queue. Providers who price contracts on projected automation levels discover that average cost per remaining chart has risen, and they then carry that difference across the entire term of the agreement.
02 / PRE-SUBMISSION VERIFICATION CAPABILITY

Undercoding is silent and overcoding is litigated

Roughly 6.4% of all reviewed claims require adjustment after compliance review, and the two possible error directions carry radically different consequences for the provider organisation involved. Undercoding quietly loses legitimate revenue and creates no liability at all for anybody, whereas overcoding instead produces repayment obligations and litigation exposure that reaches a provider board within weeks. Pre-submission review addresses both of those directions before any money at all moves, which any post-payment correction process is inherently incapable of ever doing at all.
03 / CREDENTIALING SUPPLY BUILDING

Recruiting from an empty pool is not strategy

Certified coders are now leaving the workforce considerably faster than the credentialing pipeline is replacing them, and roughly 18% of all posted positions stay unfilled beyond three months across American provider organisations. No automation decision anywhere fixes that problem for the complex charts where credentialed judgement is genuinely required. Providers who fund training and credentialing places build labour supply that competitors must then bid against them to obtain, which takes several years and addresses the only genuinely binding constraint here.
04 / DIFFICULTY FOCUSED SPECIALISATION

Compete where software improves the slowest

Emergency medicine, inpatient and complex surgical coding all resist automation, because narrative documentation and sequencing judgement determine the correct code rather than any pattern a model reliably learns from the text. Providers who build genuine capability in exactly that work hold volume that will not be automated away, priced according to what its real difficulty is actually worth. Competitors who chase the structured specialties are competing directly against software that improves annually and which prices steadily toward nothing at all.

MARKET MINDS ADVISORY · CLIENT ENGAGEMENT SUMMARY
USA Medical Coding Producer Strategic Portfolio Review and Transition Roadmap 2026·Investment Scenario on USA Medical Coding Exposure Evaluation 2025-26
CLIENT PROFILE
A coding services provider delivering outpatient, inpatient and risk adjustment work to American health systems through combined domestic and offshore operations, with reported revenue of 340 million dollars (client-reported, unverified by MMA). Roughly 74% of revenue came from high-volume outpatient coding. Audit capability existed as a small internal function and had never been offered commercially to any client.
STRATEGIC CHALLENGE
Two large clients had implemented autonomous coding for structured specialties and renegotiated rates downward, while the remaining volume proved considerably more expensive to deliver than the blended rate assumed. Management was pursuing further offshore capacity and price competitiveness. Neither addressed the composition of the work actually left behind. Work composition had never been examined.
MMA APPROACH
MMA modelled delivery cost by chart complexity across the client base, separating automatable structured work from narrative charts requiring judgement, which the company had never distinguished in its own costing. Nineteen expert interviews with revenue cycle directors, compliance officers and health information leaders established how contracting decisions are reached. The analysis treated work composition and audit exposure, rather than delivery cost, as the central issues.
KEY FINDINGS
  1. Delivery cost per chart varied by more than five times between structured and narrative work, and contracts had been priced on blended rates that ignored that distinction entirely.
  2. Both renegotiated clients had retained the company for exactly the complex charts automation could not handle, at rates set for the automatable volume that had gone.
  3. Compliance officers interviewed identified pre-submission audit as a service they would fund readily, and no incumbent provider had offered it to them at all.
  4. Credentialed coder recruitment costs had risen for four consecutive years, and the company had never considered funding training places rather than bidding for scarce candidates.

Phase 1: Phase one: reprice contracts by chart complexity rather than blended rate, since automation has permanently changed the composition of remaining work. Phase 2: Phase two: build pre-submission audit as a commercial service, reaching compliance officers who fund accuracy rather than revenue cycle directors buying throughput. Phase 3: Phase three: fund credentialing places directly instead of competing for candidates in a pool that keeps shrinking every year. Supply beats recruitment.
OUTCOME
Complexity-based repricing was implemented across renewals and margin on retained complex volume recovered materially (client-reported, unverified by MMA). A pre-submission audit service was launched and secured contracts at six accounts within two quarters, reaching compliance officers the company had never previously called upon. A funded credentialing programme began with its first cohort that autumn.
