ICD-10 Code H25.812 – Combined forms of age-related cataract, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H25.812 – Combined forms of age-related cataract, left eye
What it is
H25.812 identifies an age-related cataract in the left eye with combined lens changes, meaning more than one cataract pattern is present. Use it when documentation specifies the left eye and does not name a different cataract type.
Clinical signs
Typical findings include gradually blurred vision, glare, reduced contrast, and difficulty with night driving or reading. Clinical features vary; refer to documentation, especially when the record describes mixed nuclear, cortical, or posterior subcapsular changes.
When to use this code
Use this code when the provider documents combined forms of age-related cataract in the left eye. It is appropriate for routine ophthalmology assessments, preoperative evaluations, or follow-up visits when the left eye diagnosis is confirmed. If the laterality or cataract type is unclear, check documentation.
Do not use for
Do not use H25.812 for cataracts in the right eye, bilateral cataracts, or non-age-related cataracts. Also avoid it when the chart only says “cataract” without confirming combined age-related changes in the left eye.
Coding tip
Match the code to both the age-related category and left-eye laterality; if either detail is missing, query the provider.
