Fuchs' heterochromic cyclitis, unspecified eye

This code signifies a chronic, low-grade, non-granulomatous inflammation of the anterior uvea, specifically Fuchs' heterochromic cyclitis, affecting an unspecified eye. It is characterized by iris heterochromia, stellate keratic precipitates, and often glaucoma or cataract formation. The condition typically presents unilaterally but can rarely be bilateral.

Apply this code when documentation confirms a diagnosis of Fuchs' heterochromic cyclitis without specifying laterality (e.g., "Fuchs' heterochromic cyclitis" without further detail). This code is appropriate when the physician's notes indicate the characteristic clinical findings of this specific uveitis subtype but do not specify whether it affects the right or left eye.

• Avoid using this code if laterality (right or left eye) is documented; instead, choose the more specific code.
• Ensure the documentation clearly differentiates Fuchs' heterochromic cyclitis from other forms of uveitis or iridocyclitis.
• Code any associated complications, such as glaucoma (H40.-) or cataract (H25.-, H26.-), separately.
