ICD-10 Code H31.002 – Unspecified chorioretinal scars, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.002 – Unspecified chorioretinal scars, left eye
What it is
H31.002 identifies a chorioretinal scar in the left eye when the exact cause or type is not specified. It indicates prior damage involving the choroid and retina, leaving a residual scar.
Clinical signs
Findings may include a visible scar on retinal examination, pigmentary change, or a stable area of chorioretinal atrophy. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents an unspecified chorioretinal scar in the left eye and does not name a more specific condition. It fits follow-up visits where the scar is an existing finding rather than an active disorder. Check documentation if the record mentions prior infection, trauma, or inflammation without a definitive coded diagnosis.
Do not use for
Do not use this code for active chorioretinal inflammation, retinal detachment, or other current retinal disease. Do not assign it when the documentation specifies a different scar type or a more precise diagnosis.
Coding tip
Confirm laterality and whether the record truly says “unspecified” before assigning H31.002.
