ICD-10 Code H31.1 – Choroidal degeneration (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.1 – Choroidal degeneration
What it is
H31.1 identifies degeneration of the choroid, the vascular layer beneath the retina. Use it when the record documents choroidal degenerative change affecting the eye.
Clinical signs
Clinical features vary; refer to documentation. Findings may include choroidal atrophy or degenerative changes noted on ophthalmic examination or imaging, with associated visual complaints if recorded.
When to use this code
Use H31.1 when the clinician specifically documents choroidal degeneration or a comparable degenerative choroidal disorder. It may also fit when the ophthalmology note describes degenerative choroidal changes without a more specific diagnosis. Check documentation if the chart instead names a retinal, macular, or inflammatory condition.
Do not use for
Do not use H31.1 for unrelated retinal disease, choroiditis, or choroidal neovascularization unless choroidal degeneration is clearly documented. If the diagnosis is uncertain, check documentation.
Coding tip
Code the most specific eye diagnosis documented and confirm laterality or associated conditions when the note provides them.
