ICD-10 Code H31.29 – Other hereditary choroidal dystrophy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.29 – Other hereditary choroidal dystrophy
What it is
This code identifies a hereditary dystrophy affecting the choroid, the vascular layer beneath the retina. Use it when documentation specifies an inherited choroidal disorder that does not fit a more specific code.
Clinical signs
Clinical features vary; refer to documentation. Typical records may note inherited retinal or choroidal degeneration, visual disturbance, or characteristic fundus changes described by the eye specialist.
When to use this code
Use H31.29 when the clinician documents an other hereditary choroidal dystrophy and no more specific subtype is named. It is appropriate for ophthalmology notes, problem lists, or confirmed hereditary diagnoses. If the chart only says “chorioretinal dystrophy” or another broader term, check documentation before assigning this code.
Do not use for
Do not use this code for acquired choroidal disease, inflammatory eye disorders, or nonhereditary retinal conditions. If the diagnosis is a different hereditary choroidal dystrophy with a specific code, use that code instead.
Coding tip
Code only after you confirm the hereditary choroidal diagnosis and that no more specific ICD-10-CM option is documented.
