ICD-10 Code H35.45 – Secondary pigmentary degeneration (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H35.45 – Secondary pigmentary degeneration
What it is
Secondary pigmentary degeneration refers to pigment-related retinal changes that develop after another eye condition or injury. Use this code when the record clearly identifies a secondary, not primary, degenerative process.
Clinical signs
Clinical features vary; refer to documentation. Records may note pigmentary retinal changes, retinal degeneration, or findings linked to a prior disorder rather than an inherited pigmentary dystrophy.
When to use this code
Use H35.45 when the provider documents secondary pigmentary degeneration of the retina or a similar wording. It may apply when retinal pigment changes are attributed to another disease, trauma, or prior ocular process. Check documentation if the cause is unclear.
Do not use for
Do not use this code for primary pigmentary retinal dystrophy or retinitis pigmentosa unless the record specifically says secondary degeneration. If the documentation does not support a secondary cause, check documentation.
Coding tip
Code the documented underlying eye condition separately when it is identified and reportable.
