ICD-10 Code H35.52 – Pigmentary retinal dystrophy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.52 – Pigmentary retinal dystrophy
What it is
H35.52 identifies a retinal dystrophy marked by abnormal pigment changes in the retina. Use it when documentation names pigmentary retinal dystrophy or a closely equivalent retinal pigment disorder.
Clinical signs
Typical findings may include night vision difficulty, peripheral visual field loss, and retinal pigment abnormalities on examination. Clinical features vary; refer to documentation.
When to use this code
Use H35.52 when the clinician documents pigmentary retinal dystrophy as the diagnosis, including inherited or unspecified forms described that way. It is appropriate when the record supports a retinal dystrophic process with pigment change and no more specific code is documented. Check documentation if the note uses broader retinal degeneration terms.
Do not use for
Do not use this code for isolated retinal pigment changes without a documented dystrophy. Avoid it when a different, more specific retinal disorder or inherited retinal degeneration is clearly stated.
Coding tip
Code the exact retinal diagnosis documented and query for specificity if the record only says “retinal degeneration” or “pigment changes.”
