ICD-10 Code H20.811 – Fuchs’ heterochromic cyclitis, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.811 – Fuchs’ heterochromic cyclitis, right eye
What it is
H20.811 identifies Fuchs’ heterochromic cyclitis affecting the right eye. It is a chronic, usually low-grade inflammatory eye condition that is coded when documentation specifies the right eye.
Clinical signs
Typical findings include unilateral chronic anterior uveitis, fine keratic precipitates, and iris heterochromia or iris atrophy. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents Fuchs’ heterochromic cyclitis in the right eye, or an equivalent diagnosis of Fuchs uveitis with right-eye laterality. Confirm that the record clearly identifies the right eye and not both eyes or unspecified laterality.
Do not use for
Do not use H20.811 if the condition is documented in the left eye, both eyes, or without laterality. Do not assign it for other types of uveitis unless Fuchs’ heterochromic cyclitis is specifically stated.
Coding tip
Check the ophthalmology note for laterality and the exact term used before selecting H20.811.
