Billable

Chorioretinal disorders in diseases classified elsewhere

Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)

Is H32 an HCC code?

No. H32 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

H32 is the ICD-10-CM diagnosis code for chorioretinal disorders in diseases classified elsewhere. Inflammation or disease of the choroid and retina that occurs as a result of another disease classified elsewhere in the ICD-10 system. H32 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of choroid and retina (h30-h36).

H32 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

This is a manifestation code; always code the underlying disease first, then use H32 as a secondary diagnosis.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H32 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • This is a manifestation code; always code the underlying disease first, then use H32 as a secondary diagnosis
  • Common underlying conditions include syphilis, tuberculosis, toxoplasmosis, and other systemic infections

Excludes 1 — Do NOT code together

  • chorioretinitis (in):
  • toxoplasmosis (acquired) (B58.01)
  • tuberculosis (A18.53)

Code First

  • underlying disease, such as:
  • congenital toxoplasmosis (P37.1)
  • histoplasmosis (B39.-)
  • leprosy (A30.-)
