ICD-10 Code H25.813 – Combined forms of age-related cataract, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H25.813 – Combined forms of age-related cataract, bilateral
What it is
H25.813 identifies age-related cataracts in both eyes when more than one lens opacity type is present. It tells you the cataract is bilateral and combined, not limited to a single cataract pattern.
Clinical signs
Typical findings include gradual blurry vision, glare, reduced contrast, and trouble with night driving. Clinical features vary; refer to documentation for the documented lens changes and whether both eyes are involved.
When to use this code
Use this code when the record specifically documents combined age-related cataracts in both eyes. It fits ophthalmology assessments, problem lists, or operative planning when the provider names the condition clearly. If laterality or cataract type is unclear, check documentation.
Do not use for
Do not use it for unilateral cataract, other specified age-related cataract types, or cataracts not documented as age-related. If the note does not support both eyes and combined forms, choose the more accurate code or check documentation.
Coding tip
Confirm both laterality and cataract subtype in the assessment, not just in the exam findings.
