ICD-10 Code H26.499 – Other secondary cataract, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.499 – Other secondary cataract, unspecified eye
What it is
This code identifies a secondary cataract affecting an unspecified eye when the provider documents a posterior capsular opacity or similar lens-related clouding after prior cataract surgery. It is used when the eye is not specified in the record.
Clinical signs
Typical findings include blurred or hazy vision, glare, and reduced visual clarity after cataract extraction. Clinical features vary; refer to documentation.
When to use this code
Use H26.499 when the note states secondary cataract or posterior capsular opacification and does not identify right or left eye. Apply it for postoperative lens capsule clouding documented by the clinician. If the record names the eye, choose the more specific laterality code instead.
Do not use for
Do not use this code for a primary age-related cataract or for postoperative vision changes without documented secondary cataract. Check documentation if the cause of blurred vision is unclear.
Coding tip
Verify that the cataract is secondary and that laterality is missing before assigning H26.499.
