HCC 383: Chronic Ulcer of Skin, Except Pressure, Not Specified as Through to Bone or Muscle ICD-10-CM
CMS-HCC Category 383 (Chronic Ulcer of Skin, Except Pressure, Not Specified as Through to Bone or Muscle) is a payment HCC in the V28 Medicare Advantage risk adjustment model. For payment year 2026 it adds a risk adjustment factor between 0.343 and 0.890 to a beneficiary's RAF score depending on the payment segment (0.646 for a community, non-dual, aged enrollee). 308 ICD-10-CM diagnosis codes map to HCC 383. A more severe related category (HCC 263, HCC 379, HCC 380, HCC 381, and HCC 382) supersedes it when both are reported.
RAF Weight by Payment Segment 7 segments
| Payment Segment | Relative Factor |
|---|---|
| Community, non-dual, aged | 0.646 |
| Community, partial-benefit dual, aged | 0.660 |
| Community, full-benefit dual, aged | 0.890 |
| Community, non-dual, disabled | 0.707 |
| Community, partial-benefit dual, disabled | 0.654 |
| Community, full-benefit dual, disabled | 0.707 |
| Institutional | 0.343 |
A beneficiary is scored in exactly one segment, set by Medicaid (dual) status, aged or disabled entitlement, and residence. Factors are relative weights, not dollar amounts; new-enrollee segments score on demographics only. In the hierarchy, HCC 263 (Atherosclerosis of Arteries of the Extremities with Ulceration or Gangrene), HCC 379 (Pressure Ulcer of Skin with Necrosis Through to Muscle, Tendon, or Bone), HCC 380 (Chronic Ulcer of Skin, Except Pressure, Through to Bone or Muscle), HCC 381 (Pressure Ulcer of Skin with Full Thickness Skin Loss), and HCC 382 (Pressure Ulcer of Skin with Partial Thickness Skin Loss) supersede HCC 383 when reported together.

Questions About HCC 383
What is HCC 383 in the CMS-HCC model?
HCC 383 is CMS-HCC Category 383 (Chronic Ulcer of Skin, Except Pressure, Not Specified as Through to Bone or Muscle) in the V28 risk adjustment model. It covers 308 ICD-10-CM diagnosis codes that raise a Medicare Advantage beneficiary's risk score when documented.
What is the RAF weight for HCC 383?
For payment year 2026, HCC 383 adds 0.646 to the RAF score of a community, non-dual, aged beneficiary. The published weights range from 0.343 to 0.890 across the seven payment segments shown above.
Which categories supersede HCC 383?
HCC 263 (Atherosclerosis of Arteries of the Extremities with Ulceration or Gangrene), HCC 379 (Pressure Ulcer of Skin with Necrosis Through to Muscle, Tendon, or Bone), HCC 380 (Chronic Ulcer of Skin, Except Pressure, Through to Bone or Muscle), HCC 381 (Pressure Ulcer of Skin with Full Thickness Skin Loss), and HCC 382 (Pressure Ulcer of Skin with Partial Thickness Skin Loss) sit above HCC 383 in the hierarchy: when a beneficiary has diagnoses in both, only the more severe category is paid.
