ICD-10 Code H26.20 – Unspecified complicated cataract (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.20 – Unspecified complicated cataract
What it is
H26.20 identifies a cataract described as complicated, but the specific type or cause is not documented. Use it when the record confirms complication-related lens opacity without further detail.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include reduced vision, glare, or lens opacity, but the chart should support that the cataract is considered complicated.
When to use this code
Use this code when the provider documents a complicated cataract and does not specify the subtype or underlying cause. It also fits when the note states cataract with complication but leaves the clinical details unclear. Check the ophthalmology assessment for wording that supports “unspecified.”
Do not use for
Do not use this code for routine age-related cataracts or for cataracts with a clearly documented specific type. If the record names another cause or laterality detail, code that documented condition instead.
Coding tip
Look for the exact phrase “complicated cataract” and confirm that no more specific cataract code is documented.
