HCC 248: Intracranial Hemorrhage ICD-10-CM
CMS-HCC Category 248 (Intracranial Hemorrhage) is a payment HCC in the V28 Medicare Advantage risk adjustment model. For payment year 2026 it adds a risk adjustment factor between 0.081 and 0.377 to a beneficiary's RAF score depending on the payment segment (0.239 for a community, non-dual, aged enrollee). 53 ICD-10-CM diagnosis codes map to HCC 248. It sits at the top of its hierarchy: no other condition category supersedes it.
RAF Weight by Payment Segment 7 segments
| Payment Segment | Relative Factor |
|---|---|
| Community, non-dual, aged | 0.239 |
| Community, partial-benefit dual, aged | 0.313 |
| Community, full-benefit dual, aged | 0.377 |
| Community, non-dual, disabled | 0.180 |
| Community, partial-benefit dual, disabled | 0.183 |
| Community, full-benefit dual, disabled | 0.332 |
| Institutional | 0.081 |
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. HCC 248 in turn supersedes HCC 249 (Ischemic or Unspecified Stroke).
