ICD-10 Code H25.019 – Cortical age-related cataract, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H25.019 – Cortical age-related cataract, unspecified eye
What it is
This code identifies an age-related cortical cataract affecting an unspecified eye. Use it when the chart documents cortical lens opacity from aging but does not specify right, left, or bilateral eye.
Clinical signs
Typical findings include gradual blurred vision, glare, and reduced contrast, often with spoke-like cortical opacities on eye exam. Clinical features vary; refer to documentation.
When to use this code
Use H25.019 when the provider documents cortical age-related cataract and does not identify the eye involved. It also fits when laterality is unavailable in the record or cannot be confirmed from the assessment.
Choose the more specific laterality code if documentation names the right, left, or both eyes. If the note only says “cataract” without age-related cortical wording, check documentation before coding.
Do not use for
Do not use this code for traumatic, congenital, or other non-age-related cataracts. Do not use it when the record clearly specifies the affected eye and a laterality code is available.
Coding tip
Confirm both the cataract type and laterality in the ophthalmology note before assigning H25.019.
