ICD-10 Code H26.051 – Posterior subcapsular polar infantile and juvenile cataract, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H26.051 – Posterior subcapsular polar infantile and juvenile cataract, right eye
What it is
This code identifies a posterior subcapsular polar cataract affecting the right eye in an infant or child. It describes a lens opacity near the back of the lens, documented as congenital or juvenile in onset.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include decreased visual acuity, glare, or abnormal red reflex, with the cataract noted on eye examination as involving the posterior subcapsular polar lens region.
When to use this code
Use H26.051 when the record clearly states a posterior subcapsular polar infantile or juvenile cataract in the right eye. This is appropriate for ophthalmology notes, problem lists, or surgical evaluations that specify laterality and the pediatric or juvenile nature of the cataract.
If the documentation only says “cataract” or does not identify the right eye, check documentation before assigning this code. You should code the most specific documented diagnosis, not a general lens opacity.
Do not use for
Do not use this code for cataracts in the left eye, both eyes, or unspecified eye. It is also not correct for age-related cataracts or other cataract types that are documented separately.
Coding tip
Verify both laterality and the infantile or juvenile description before coding H26.051.
