ICD-10 Code H31.001 – Unspecified chorioretinal scars, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.001 – Unspecified chorioretinal scars, right eye
What it is
This code identifies a chorioretinal scar in the right eye when the chart does not specify the cause or type. It reflects a healed area involving the choroid and retina.
Clinical signs
Findings may include a visible scar on funduscopic exam, pigmentary change, or a stable area of retinal-choroidal damage. Clinical features vary; refer to documentation.
When to use this code
Use H31.001 when the provider documents an unspecified chorioretinal scar limited to the right eye. It is appropriate when the record notes an old scar, but does not identify a more specific diagnosis.
Choose this code for documented right-eye scarring without laterality ambiguity and without a more detailed etiology. Check documentation if the note describes active inflammation, trauma, or another specific retinal disorder.
Do not use for
Do not use this code for scars in the left eye, bilateral findings, or retinal conditions that have a more specific ICD-10 code. Do not assign it when the provider documents an active disease rather than a residual scar.
Coding tip
Confirm laterality and whether the finding is truly a scar before coding; unspecified eye findings often need a different code.
