Fuchs' heterochromic cyclitis, left eye

This code describes a chronic, typically unilateral, low-grade inflammation of the iris and ciliary body, specifically affecting the left eye. It is characterized by heterochromia (difference in iris color), stellate keratic precipitates, and often glaucoma or cataract development.

Use this code when documentation explicitly states a diagnosis of Fuchs' heterochromic cyclitis affecting the patient's left eye. Supporting documentation should detail the characteristic clinical findings, such as iris color changes, specific types of keratic precipitates, and the affected eye.

• Ensure the laterality is accurately documented as "left eye" to support this specific code.
• Do not confuse with other forms of uveitis or iridocyclitis; Fuchs' heterochromic cyclitis has distinct clinical features.
• Code any associated complications, such as glaucoma (H40.-) or cataract (H25.-, H26.-), separately.
