V28 HCC 248
Intracranial Hemorrhage
Under the CMS-HCC V28 risk adjustment model (PY2026 Medicare Advantage), HCC 248 has a source-labeled community non-dual aged reference coefficient of 0.239, and 53 ICD-10-CM diagnosis codes appear in its official mapping.
RAF factors
The community factor varies by Medicaid and originally-disabled status; the institutional factor applies to long-term-institutional members. These are the CMS-HCC V28 PY2026 relative factors.
These are source-labeled code-level HCC coefficient references, not a full member score. Use the RAF Calculator with complete member context for CMS-HCC V28 PY2026. No score is shown unless every required source and calculation check passes.
