ICD-10 Code H31.22 – Choroidal dystrophy (central areolar) (generalized) (peripapillary) (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.22 – Choroidal dystrophy (central areolar) (generalized) (peripapillary)
What it is
H31.22 identifies choroidal dystrophy, a degenerative disorder affecting the choroid beneath the retina. The listed terms describe recognized patterns: central areolar, generalized, or peripapillary involvement.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include progressive visual disturbance and characteristic choroidal atrophy on eye examination or imaging.
When to use this code
Use this code when the provider documents choroidal dystrophy and specifies central areolar, generalized, or peripapillary involvement. Apply it for confirmed degenerative choroidal disease, not for nonspecific retinal complaints alone. Check documentation if the record only mentions chorioretinal changes.
Do not use for
Do not use this code for unrelated retinal dystrophies, choroiditis, or other inflammatory eye disorders. If the diagnosis is uncertain or not specifically documented as choroidal dystrophy, check documentation.
Coding tip
Code the exact documented subtype, and do not assume laterality or severity when the note does not state it.
