Question 1

What is ICD-10 code H32?

Accepted Answer

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, V24, ESRD, or RxHCC 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.

Accepted Answer

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 H32 is not a CMS-HCC V28 payment code in the verified current source, so MEAT is not the payment hook.
