ICD-10 Code H59.032 – Cystoid macular edema following cataract surgery, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.032 – Cystoid macular edema following cataract surgery, left eye
What it is
This code identifies cystoid macular edema that develops after cataract surgery in the left eye. It means fluid has collected in the macula, reducing central vision.
Clinical signs
Common findings include blurred or distorted central vision after cataract surgery, with macular swelling seen on eye examination or imaging. Clinical features vary; refer to documentation.
When to use this code
Use H59.032 when the provider documents cystoid macular edema as a postoperative complication of cataract surgery and specifies the left eye. Apply it only when the relationship to surgery is clearly stated or clinically established in the record.
If the edema is in another eye, or the note does not link it to cataract surgery, do not assume this code. Check documentation for laterality and cause before assigning.
Do not use for
Do not use this code for macular edema from diabetes, retinal disease, or other non-surgical causes. It also should not be used when postoperative edema is documented without cataract surgery as the cause.
Coding tip
Verify both the postoperative cause and the left-eye laterality before coding H59.032.
