CMS HCC Risk Adjustment & RAF Score Benchmarker

CMS is actively transitioning Medicare Advantage risk adjustment to the v28 model. Measure your clinical RAF differential, model capitation revenue impacts across county benchmarks, and implement MEAT documentation defensibility to protect practice cash flow.

CMS-HCC v28 vs v24 Risk Adjustment Engine

CMS HCC Risk Adjustment & RAF Score Benchmarker

Model patient risk score erosion under the new CMS-HCC v28 risk model. Calculate Medicare Advantage capitation revenue differentials, identify disease interaction bonuses, and view MEAT documentation defensibility criteria.

CMS 2025 Transition Note: For 2025 dates of service, CMS utilizes a blended payment model of 67% v28 + 33% v24. Uncomplicated diabetes and CKD Stage 3 have been removed from v28, driving an average 3%–12% RAF score contraction for practices lacking high-specificity documentation.

2. Select Chronic Clinical Conditions

Check all active chronic conditions substantiated in the medical record.

Diabetes Mellitus without ComplicationE11.9, E10.9Dropped in v28

CMS removed uncomplicated diabetes in v28. Document specific manifestations (neuropathy, nephropathy) to capture risk.

v24:+0.105
v28:+0.000
Diabetes with Chronic ComplicationsE11.21 (Nephropathy), E11.40 (Neuropathy), E11.319 (Retinopathy)

Coefficients reduced by ~45% in v28. Comprehensive organ system documentation required to justify disease acuity.

v24:+0.302
v28:+0.166
MEAT Documentation Criteria: Link microvascular end-organ damage directly to diabetes. Document eGFR/microalbuminuria, monofilament exam, or dilated eye exam.
Heart Failure (Systolic, Diastolic, Combined)I50.22 (Chronic systolic), I50.32 (Chronic diastolic), I50.9

Maintained comparable weight in v28. Echo ejection fraction and NYHA functional class must be explicitly recorded annually.

v24:+0.368
v28:+0.360
MEAT Documentation Criteria: Document NYHA functional class (I–IV), current EF%, stability/compensation status, and diuretic/ACE/beta-blocker dosage.
Chronic Kidney Disease — Stage 3N18.30, N18.31, N18.32Dropped in v28

Removed in v28. Monitor eGFR closely; patients progressing to eGFR <30 qualify for CKD Stage 4 (HCC 328).

v24:+0.070
v28:+0.000
Chronic Kidney Disease — Stage 4 (Severe)N18.4

Retained in v28 with slight coefficient recalibration. Must document eGFR 15–29 mL/min and nephrology referral status.

v24:+0.289
v28:+0.240
Chronic Kidney Disease — Stage 5 / ESRDN18.5, N18.6, Z99.2 (Hemodialysis)

Increased coefficient weight in v28 reflecting intensive clinical resources required for end-stage renal management.

v24:+0.289
v28:+0.370
COPD, Emphysema & Chronic BronchitisJ44.9, J43.9, J42

Stable coefficient across models. Annual documentation must capture exacerbation history and maintenance inhaler adherence.

v24:+0.335
v28:+0.330
MEAT Documentation Criteria: Document baseline dyspnea on exertion, oxygen saturation, spirometry (FEV1), inhaler regimen (LABA/LAMA/ICS), and exacerbation triggers.
Peripheral Vascular Disease / Intermittent ClaudicationI73.9, I70.201, I70.202Dropped in v28

Uncomplicated PVD dropped in v28! Only peripheral disease with critical limb ischemia or ulceration maps to v28 HCC 263/264.

v24:+0.288
v28:+0.000
Atrial Fibrillation & Specified ArrhythmiasI48.0, I48.19, I48.20, I48.91

Recalibrated slightly downward in v28. Anticoagulation tracking and rhythm vs rate control strategy must be documented.

v24:+0.268
v28:+0.220
Major Depressive Disorder (Single/Recurrent)F32.9, F33.0, F33.1, F33.2

Maintained strong value. Require documented severity (mild/moderate/severe), remission status, and PHQ-9 scoring.

v24:+0.309
v28:+0.300
Rheumatoid Arthritis & Autoimmune Connective TissueM06.9, M05.79, M32.9 (SLE)

Slight recalibration. Specific disease activity scoring (CDAI/RAPID3) and DMARD/biologic drug monitoring required.

v24:+0.423
v28:+0.380
Morbid Obesity (BMI >= 40 or BMI >= 35 with Comorbidity)E66.01 + Z68.41–Z68.45

Both the diagnosis code (E66.01) AND the corresponding BMI secondary code (Z68.41–Z68.45) must appear on the same claim.

v24:+0.273
v28:+0.250
