HCC Risk Adjustment / Engine V28

Recapture the conditions already in the chart. Then prove them.

Most lost risk-adjustment revenue is not undiagnosed disease. It is chronic conditions documented somewhere in the record that never made it onto a claim this year. The fix is not more diagnoses. It is disciplined recapture, gated on MEAT-supported documentation so every recaptured code survives a CMS RADV look-back.

The short version: Find the suspect (a condition coded in a prior year or buried in a note), confirm it was Monitored, Evaluated, Assessed, or Treated in a face-to-face encounter this year, and only then let it flow to a claim. No MEAT, no recapture. That single gate is the difference between a defensible RAF and an audit finding.

CY2026

First fully phased-in CMS-HCC V28 payment year

M.E.A.T.

The documentation test every recapture must pass

RADV

Extrapolated audit recovery, no fee-for-service adjuster

FY2026 ICD-10-CM guidelines in effect for the DOS

The gap, in three boxes

A condition can be true, documented, and still worth zero

Risk adjustment resets every calendar year. A diagnosis captured last year does not carry forward on its own. If it is not coded from a qualifying encounter this year, the model treats the member as if the condition is gone.

Present

In the record

Prior-year HCC, a problem-list entry, a med that implies the condition, or a specialist note. Real, but not on a 2026 claim.

→

Suspect

Flagged, not coded

The engine surfaces it as a recapture candidate. This is a lead, not a code. Nothing bills yet.

→

Recaptured

MEAT-confirmed

A 2026 face-to-face note shows Monitor / Evaluate / Assess / Treat. Now, and only now, it flows to the claim.

The gate

MEAT is the standard that keeps recapture honest

MEAT is the documentation framework auditors read against Section IV of the ICD-10-CM Official Guidelines, which say to code conditions that require or affect patient care, treatment, or management. A condition that is only listed, with no clinical action, fails. Our engine will not recapture it.

Monitor

Track it

Signs, symptoms, disease progression, labs trending. The note shows the condition is being watched.

Evaluate

Review it

Test results, medication response, exam findings tied to the condition are reviewed and recorded.

Assess

Judge it

Clinical assessment, ordering, discussion, counseling, or a status statement in the provider's own words.

Treat

Act on it

Medications, therapies, referrals, or a plan. Evidence the condition drove a care decision this year.

Every dollar here is gated on documentation that survives RADV. Un-MEAT-ed suspects are excluded on purpose.

Defensible vs fragile

What survives an audit, and what gets clawed back

The CMS-HCC RADV Final Rule (CMS-4185-F2) removed the fee-for-service adjuster and allows CMS to extrapolate audit findings across the contract. That turns a handful of unsupported codes into a large, projected recovery. The recapture that holds up looks nothing like the one that does not.

Test	Fragile recapture	MEAT-gated recapture
Source of the diagnosis	Prior-year claim carried forward	Coded from a 2026 face-to-face encounter
Documentation	Problem-list entry only	Monitor / Evaluate / Assess / Treat in the note
ICD-10-CM guideline fit	Listed, not managed	Affects care, treatment, or management (Section IV)
Specificity	Unspecified default	Highest documented specificity, laterality preserved
RADV posture	Extrapolated finding risk	Chart pulls to the same conclusion as the code
Provider attestation	Inferred from a medication	Assessment stated in the provider's own words

Why now

The V28 phase-in makes clean recapture the whole game

CY2024

V28 phase-in begins

CMS starts the three-year transition to the 2024 CMS-HCC model, blending V24 and V28 payment.

CY2025

Blend deepens

More weight shifts to V28. Constrained coefficients and remapped HCCs mean prior-year capture no longer predicts current-year value.

CY2026

V28 fully in effect

Per the CY2026 Medicare Advantage and Part D Rate Announcement, risk scores run entirely on V28. Every recapture must be earned in-year on this year's model.

Oct 1, 2025

FY2026 ICD-10-CM guidelines live

The dates of service you are recapturing for 2026 are coded under the FY2026 Official Guidelines for Coding and Reporting. The engine codes to the release that matches the DOS, never a stale one.

Inside Engine V28

How the recapture actually runs

A suspect list is easy. A suspect list that only bills what the chart can defend is the product. Every candidate passes through the same gate before it touches a claim.

Surface suspects

Cross-read prior-year HCCs, problem lists, meds, labs, and specialist notes against this year's coded claims to flag the gaps.

Map to V28

Translate each ICD-10-CM code to its CY2026 CMS-HCC V28 category so you know the real coefficient, not a V24 assumption.

Run the MEAT gate

Scan the in-year encounter for Monitor, Evaluate, Assess, Treat evidence. No MEAT means the suspect stays a suspect.

Check specificity

Enforce highest-specificity coding and laterality against the FY2026 guidelines. Never downgrade to unspecified to force a match.

Build the RADV packet

Bind the code to the exact chart page and MEAT language, so a later audit pull lands on the same conclusion.

Release to claim

Only confirmed, documented, specificity-checked recaptures flow. The rest go back to the provider as a documentation query.

The guidelines this model is built on

V28

CMS-HCC Model V28, CY2026 Rate Announcement

The 2024 CMS-HCC risk adjustment model, fully phased in for calendar year 2026 per the CMS Medicare Advantage and Part D Rate Announcement. Governs which conditions map to a payment HCC and at what coefficient.

ICD-10

ICD-10-CM Official Guidelines for Coding and Reporting, FY2026

Effective for dates of service on and after October 1, 2025. Section IV directs coding of conditions that require or affect patient care, treatment, or management, and enforces highest-specificity code assignment.

MEAT

MEAT documentation standard (Monitor, Evaluate, Assess, Treat)

The industry-accepted framework for demonstrating that a documented condition was clinically active in the encounter, used to judge whether a diagnosis is codeable and audit-supportable.
