ICD-10 Code H59.813 – Chorioretinal scars after surgery for detachment, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.813 – Chorioretinal scars after surgery for detachment, bilateral
What it is
H59.813 identifies chorioretinal scarring in both eyes that occurs after surgery for retinal detachment. Use it when the chart documents postoperative scar changes involving the choroid and retina.
Clinical signs
Findings may include visible chorioretinal scars on eye examination and a documented history of prior detachment repair. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider states bilateral chorioretinal scars are a postoperative result of retinal detachment surgery. It fits follow-up visits, problem lists, or ophthalmology notes describing stable scar tissue after repair. Code only when the postoperative relationship is clear.
Do not use for
Do not use this code for retinal detachment itself, uncomplicated postoperative follow-up, or scars from causes other than detachment surgery. Check documentation if the laterality or postoperative cause is unclear.
Coding tip
Confirm both the bilateral laterality and the explicit link to prior detachment surgery before assigning H59.813.
