ICD-10 Code H35.453 – Secondary pigmentary degeneration, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.453 – Secondary pigmentary degeneration, bilateral
What it is
H35.453 identifies secondary pigmentary degeneration affecting both eyes. It describes pigmentary retinal change that results from another underlying condition rather than a primary inherited retinal disorder.
Clinical signs
Findings may include bilateral retinal pigment changes seen on eye examination, sometimes with reduced visual function. Clinical features vary; refer to documentation.
When to use this code
Use H35.453 when the clinician documents secondary pigmentary degeneration in both eyes. It is appropriate when the record supports a bilateral retinal pigmentary process caused by another condition, and the provider specifies both sides.
Code only when the documentation clearly distinguishes this from primary pigmentary retinal degeneration or an unspecified retinal disorder. Check documentation if the underlying cause is not stated.
Do not use for
Do not use this code for primary pigmentary retinal dystrophy or for unilateral disease. If the chart does not confirm bilateral involvement or secondary etiology, choose a more specific or unspecified code. Check documentation.
Coding tip
Verify both laterality and the word “secondary” in the assessment before assigning H35.453.
