V28 HCC 213
Cardio-Respiratory Failure and Shock
Under the CMS-HCC V28 risk adjustment model (PY2026 Medicare Advantage), HCC 213 has a source-labeled community non-dual aged reference coefficient of 0.37, and 36 ICD-10-CM diagnosis codes appear in its official mapping. In the V28 hierarchy it is superseded by HCC 211, HCC 212 when a more severe category in the same disease group is also present.
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.
V28 hierarchy
Trumped by: HCC 211, HCC 212 (a more severe category in the same disease group supersedes this one).
