ICD-10 Code H31.101 – Choroidal degeneration, unspecified, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.101 – Choroidal degeneration, unspecified, right eye
What it is
This code identifies degeneration of the choroid in the right eye when the record does not specify the exact type. It is used for a documented choroidal disorder affecting the posterior eye layer.
Clinical signs
Clinical features vary; refer to documentation. Findings may include choroidal atrophy or other degenerative changes noted on ophthalmic exam or imaging, with symptoms depending on the underlying eye disease.
When to use this code
Use this code when the clinician documents choroidal degeneration in the right eye but does not name a more specific subtype. It is appropriate when the chart clearly identifies the right eye and the diagnosis remains unspecified. Check documentation if the note mentions another retinal or choroidal condition.
Do not use for
Do not use it for left-eye or bilateral disease, or when a more specific choroidal diagnosis is documented. Avoid it if the condition is actually retinal, macular, or another non-choroidal disorder.
Coding tip
Confirm laterality and specificity in the ophthalmology note before assigning H31.101.
