ICD-10 Code H35.451 – Secondary pigmentary degeneration, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.451 – Secondary pigmentary degeneration, right eye
What it is
This code identifies pigmentary degeneration affecting the right eye that is secondary to another ocular process. Use it when the record specifies the right eye and documents a secondary cause or associated condition.
Clinical signs
Clinical features vary; refer to documentation. Findings may include retinal pigment changes noted on examination, often with related visual complaints or prior eye disease in the same eye.
When to use this code
Use H35.451 when the clinician documents secondary pigmentary degeneration limited to the right eye. It is appropriate when the note clearly links the degeneration to another retinal or ocular disorder and laterality is specified. Check documentation if the cause or eye is unclear.
Do not use for
Do not use this code for primary pigmentary retinal disorders or for bilateral disease unless the record supports right-eye involvement only. If the documentation does not state secondary degeneration, check documentation.
Coding tip
Verify both laterality and the secondary nature of the condition before assigning H35.451.
