ICD-10 Code H59.812 – Chorioretinal scars after surgery for detachment, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.812 – Chorioretinal scars after surgery for detachment, left eye
What it is
This code identifies a chorioretinal scar in the left eye that developed after surgery performed to repair retinal detachment. It describes a postoperative structural change, not the detachment itself.
Clinical signs
Findings usually include a documented chorioretinal scar on eye exam in the left eye after prior detachment repair. Clinical features vary; refer to documentation.
When to use this code
Use H59.812 when the provider documents a chorioretinal scar in the left eye as a result of prior retinal detachment surgery. It is appropriate for postoperative follow-up or when the scar is a current documented condition. Do not use it for an active detachment without postoperative scarring.
Do not use for
Do not use this code for retinal detachment itself, scars from non-surgical causes, or scarring in the wrong eye. Check documentation if the cause or laterality is unclear.
Coding tip
Verify both the postoperative cause and left-eye laterality before assigning H59.812.
