Other vascular disorders of iris and ciliary body, bilateral

This code signifies a non-inflammatory condition affecting the blood vessels of both the iris and ciliary body, excluding specific diagnoses like rubeosis iridis or iris atrophy. These disorders can manifest as vascular anomalies, hemorrhages, or other circulatory disturbances within these anterior segment structures.

Apply this code when documentation specifies a bilateral vascular disorder of the iris and ciliary body that is not otherwise classified. This includes conditions such as bilateral iris neovascularization not explicitly termed rubeosis, or bilateral ciliary body hemorrhage without a more specific diagnosis. Ensure the medical record clearly indicates involvement of both eyes.

• Do not use for unilateral conditions; instead, select the appropriate laterality (H21.1X1 or H21.1X2).
• Distinguish from rubeosis iridis (H21.11x) or iris atrophy (H21.2x) which have more specific codes.
• Confirm documentation explicitly states "bilateral" or describes findings in both eyes.
