2026 ICD-10-CM Diagnosis Code H35.452 – Secondary pigmentary degeneration, left eye
What it is
This code identifies pigmentary degeneration affecting the left retina that is secondary to another condition or process. Use it when documentation specifies the left eye and a secondary cause or association.
Clinical signs
Findings may include retinal pigment changes seen on eye examination, with visual symptoms varying by the underlying disorder. Clinical features vary; refer to documentation.
When to use this code
Use H35.452 when the provider documents secondary pigmentary degeneration in the left eye, such as in an ophthalmology assessment or problem list. Code the documented laterality exactly as recorded. If the cause is stated, you may need an additional code for the underlying condition.
Do not use for
Do not use this code for unspecified eye involvement or for primary pigmentary retinal disorders. Check documentation if the record does not clearly identify the left eye or confirms a different retinal diagnosis.
Coding tip
Verify laterality and any documented underlying cause before assigning H35.452.
