ICD-10 Code H31.00 – Unspecified chorioretinal scars (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.00 – Unspecified chorioretinal scars
What it is
H31.00 identifies chorioretinal scarring when the chart does not specify the cause, site details, or whether the scar is active. Use it for documented scars involving the choroid and retina together.
Clinical signs
Findings may include a visible chorioretinal scar on fundus exam, often as a healed area of pigment change or atrophy. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chorioretinal scars but does not name a more specific diagnosis. It also fits cases where the record confirms an old, stable scar without further detail. If the etiology or laterality is stated elsewhere, code to that documentation instead.
Do not use for
Do not use this code for active chorioretinal inflammation, retinal scars alone, or choroidal lesions without retinal involvement. Check documentation if the note describes a different posterior segment disorder.
Coding tip
Code only when the provider clearly documents a chorioretinal scar and no more specific option is supported.
