ICD-10 Code H25.043 – Posterior subcapsular polar age-related cataract, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H25.043 – Posterior subcapsular polar age-related cataract, bilateral
What it is
This code identifies age-related cataracts affecting the posterior subcapsular polar region in both eyes. Use it when documentation shows a bilateral, senile cataract pattern in that specific lens location.
Clinical signs
Clinical features vary; refer to documentation. Commonly, cataracts cause gradual blurred vision, glare, and reduced reading vision, with posterior subcapsular involvement often noted on eye examination.
When to use this code
Use H25.043 when the provider documents bilateral posterior subcapsular polar age-related cataracts. It is appropriate for ophthalmology assessments, preoperative evaluations, and problem lists when both eyes are specifically described. If the record does not clearly state bilateral involvement, check documentation before coding.
Do not use for
Do not use this code for traumatic, congenital, diabetic, or other non-age-related cataracts. Also avoid it when the cataract type or laterality is not documented clearly.
Coding tip
Confirm both the age-related cause and bilateral posterior subcapsular location before assigning H25.043.
