ICD-10 Code H59.819 – Chorioretinal scars after surgery for detachment, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.819 – Chorioretinal scars after surgery for detachment, unspecified eye
What it is
This code identifies chorioretinal scarring that develops after retinal detachment surgery, when the affected eye is not specified. It reflects a postoperative eye finding, not the detachment itself.
Clinical signs
Findings may include visible chorioretinal scar tissue on retinal examination after prior detachment repair. Clinical features vary; refer to documentation.
When to use this code
Use H59.819 when the record documents chorioretinal scars as a complication or sequela of prior detachment surgery and laterality is not stated. You should code it when the provider links the scar to the surgery, not to an active detachment. Check documentation if the note only mentions prior retinal surgery without a scar diagnosis.
Do not use for
Do not use this code for an active retinal detachment, unrelated retinal scars, or postoperative findings in a specified eye when a laterality-specific code is available. Do not guess the cause.
Coding tip
Confirm the scar is documented as post-surgical and that the eye is unspecified before assigning H59.819.
