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 the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.

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, source-labeled coefficient references, and MEAT documentation criteria for H32 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
