Risk Adjustment / HCC Engine V28

Chronic-condition recapture under V28: suspect it, document it, map it every year.

2026 is the first payment year that runs on 100% CMS-HCC V28. HCCs do not carry forward. Every chronic condition resets to zero on January 1 and has to be earned back through a face-to-face encounter before December 31.

The short answer

Recapture is the annual discipline of re-documenting and re-coding each of a patient's chronic conditions inside the calendar year, then confirming every ICD-10-CM code still maps to a payment HCC under the V28 crosswalk. Miss the encounter, or code a diagnosis that V28 dropped, and the condition simply disappears from the risk score. The checklist below is how our V28 engine works a panel from suspecting to mapping.

Why recapture, every year

The risk score resets. The chart does not remind you.

A diabetic with CKD coded perfectly last year contributes nothing to this year's score until a clinician sees the patient and documents it again inside the service year. Recapture is a calendar problem before it is a coding problem.

The 2026 recapture clock

One panel, one calendar year. The earlier a suspect closes, the more runway you have to fix documentation before the sweep deadline.

Q1 / Jan
Score resets to zero. Load prior-year HCCs and open the suspect list for the panel.
Q2 / Apr
Drive AWV and chronic-care visits. First look at open suspects vs captured.
Q3 / Jul
Mid-year gap sweep. Chase the persistent non-responders and specialist-only conditions.
Q4 / Dec
Final recapture push. Every open suspect closed or documented as clinically resolved before Dec 31.
The infographic checklist

Six steps: from suspecting a condition to mapping it under V28.

This is the workflow our V28 engine runs on every panel. Print it, tape it to the wall, hold every recapture visit against it.

101
Suspect

Build the suspect list before the visit

Recapture starts with a hypothesis, not a blank chart. Pull every signal that a chronic condition is likely present but unconfirmed this year.

Prior-year HCCs. Last year's captured conditions are this year's first suspects.
Clinical signals. Labs (A1c, eGFR), active Rx, DME, and claims history that imply an unaddressed condition.
V28 sensitivity. Flag conditions in categories V28 constrained, so the panel is not carrying a false sense of coverage.
202
Schedule

Get the patient in front of a clinician

No face-to-face, no capture. The Annual Wellness Visit is the natural container for a full chronic-condition review.

Book the AWV early. An early visit leaves months of runway to correct documentation gaps.
Front-load the suspect list into the pre-visit summary so nothing is reviewed from memory.
Acceptable encounter type. Confirm the visit meets CMS risk-adjustment face-to-face requirements before you count on it.
303
Document

MEAT on every chronic condition

A condition named in the assessment but not worked is a RADV target. Each condition needs evidence it was actively managed.

M-E-A-T. Monitor, Evaluate, Assess, Treat. At least one, tied to the specific diagnosis.
Status and linkage. Document the causal link for combination conditions, for example diabetes with CKD, not two loose diagnoses.
Signed and dated by the rendering provider, inside the service year.
404
Code

Code to the FY2026 ICD-10-CM specificity

The score is only as good as the code. General codes and unconfirmed statuses leak risk even when the documentation is strong.

Use the FY2026 code set effective October 1, 2025. Retired and expanded codes both change the map.
Highest specificity. Laterality, stage, and complication where the record supports it. Example E11.22 over E11.9.
Active only. No history-of, no rule-out. Only confirmed, currently managed conditions.
505
Map

Run the code through the V28 crosswalk

This is where 2026 bites. A code that mapped cleanly under V24 may map to nothing, or to a different HCC, under V28. Never assume it carried over.

Confirm the map exists. Check the CMS-HCC V28 ICD-10-to-HCC mapping. Some V24-payable codes no longer map.
Watch renumbered categories. V28's 115 HCCs are renumbered. The label you remember from V24 likely points somewhere else.
Respect hierarchies. Higher-severity HCCs supersede lower ones in the same family. Capture the most specific supported condition.

Validate & close

Reconcile suspect vs captured, make it RADV-ready

Recapture is not done when the claim drops. It is done when the gap is closed and the documentation would survive an audit.

Close the loop. Every suspect ends as captured, or documented as clinically resolved or not present.
Audit posture. Documentation supports the code under RADV standards. If it would not survive a chart pull, it is not captured.
Carry the open list into next year's suspect file so nothing goes quietly dark.
What actually changed

V24 habits will silently under-capture on the V28 crosswalk.

The model transition finished for the 2026 payment year. Coding on last year's muscle memory is the most common way a well-run panel loses risk it earned.

Where recapture leaks

Three traps that drain a V28 panel

Trap 01

"It mapped last year."

A code copied forward from a V24 workflow that no longer maps under V28. It looks captured on the claim and contributes zero to the score.

FixRe-run every recaptured code through the current V28 crosswalk, not last year's.
Trap 02

Named, not worked

The condition appears in the assessment but has no monitoring, evaluation, or treatment tied to it. A clean RADV takedown.

FixRequire MEAT per condition at documentation, step 3, before the code is ever assigned.
Trap 03

The December scramble

Suspects left open until Q4 collide with no-shows and holiday scheduling. The panel runs out of calendar before it runs out of conditions.

FixWork the suspect list against the recapture clock, with a mid-year sweep, not a year-end sprint.

Recapture is a workflow problem. We run the workflow.

Our V28 risk-adjustment engine builds the suspect list, drives the in-year encounter, checks MEAT, and confirms every code still maps on the current crosswalk, so your panel keeps the risk it actually earned. No fabricated lift, just the conditions that are documented, coded, and mapped correctly.

Educational reference for risk-adjustment and coding teams. Category counts and phase-in status reflect the CMS-HCC V28 model and the CY2026 Rate Announcement; always validate specific codes against the current CMS-HCC V28 ICD-10-to-HCC mapping and the FY2026 ICD-10-CM code set.
