Secondary pigmentary degeneration, right eye

This code signifies a condition affecting the right eye where the retina or other ocular structures degenerate due to the abnormal accumulation or migration of pigment. This pigmentary change is secondary to another underlying ocular or systemic disease process, rather than being a primary inherited or idiopathic condition.

Apply this code when documentation explicitly states "secondary pigmentary degeneration" affecting the right eye. This diagnosis is typically made by an ophthalmologist based on funduscopic examination findings and may be associated with conditions like trauma, inflammation, or vascular occlusions.

• Ensure laterality is clearly documented as "right eye" to support this specific code.
• Always code the underlying primary condition causing the secondary pigmentary degeneration first.
• Do not confuse with primary pigmentary retinopathies (e.g., retinitis pigmentosa) which have different ICD-10-CM codes.
