ICD-10 Code H26.49 – Other secondary cataract (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.49 – Other secondary cataract
What it is
H26.49 identifies a secondary cataract that is not described by a more specific code. It refers to clouding or visual impairment that develops after another eye condition or procedure; check documentation for the exact cause.
Clinical signs
Patients may report blurred or reduced vision, glare, or difficulty seeing clearly, especially after prior cataract surgery or other ocular disease. Clinical features vary; refer to documentation.
When to use this code
Use H26.49 when the record documents a secondary cataract but does not specify a more precise subtype. It is appropriate when the provider identifies the condition as secondary and no better code is available. Confirm laterality, if documented elsewhere, and code additional eye findings as directed.
Do not use for
Do not use this code for primary age-related cataract or other cataract types with a more specific ICD-10 option. Do not assign it when the documentation does not support a secondary cataract diagnosis.
Coding tip
Before assigning H26.49, verify that the note says “secondary cataract” and that no more specific cataract code applies.
