ICD-10 Code H31.103 – Choroidal degeneration, unspecified, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.103 – Choroidal degeneration, unspecified, bilateral
What it is
H31.103 identifies unspecified degeneration of the choroid in both eyes. Use it when the record documents bilateral choroidal degeneration but does not name a more specific type or cause.
Clinical signs
Clinical features vary; refer to documentation. Findings may include choroidal atrophy or pigmentary change on eye examination, with vision symptoms depending on the underlying degeneration.
When to use this code
Use this code when the provider documents bilateral choroidal degeneration and no further detail is available. It is also appropriate when the note confirms choroidal degeneration in both eyes but does not specify etiology, pattern, or severity. Check documentation if another retinal or choroidal disorder is described more precisely.
Do not use for
Do not use this code for unilateral choroidal degeneration or for conditions limited to the retina, macula, or optic nerve. If the record names a specific choroidal disorder, code the documented diagnosis instead.
Coding tip
Verify laterality carefully; H31.103 is for bilateral disease only, and unspecified means you should not add detail that is not documented.
