Chronic angle-closure glaucoma, bilateral, stage unspecified

This code signifies a chronic form of glaucoma characterized by a narrow or closed anterior chamber angle, leading to impaired aqueous humor outflow and elevated intraocular pressure, affecting both eyes. The specific stage of the disease progression is not documented or determined.

Use this code when documentation clearly indicates chronic angle-closure glaucoma affecting both eyes, but the physician has not specified a stage (e.g., mild, moderate, severe, or end-stage). This code is appropriate when the clinical picture confirms the chronic nature and bilateral involvement without further staging details.

• Ensure documentation explicitly states "chronic" and "bilateral" angle-closure glaucoma.
• Avoid using this code if a specific stage of glaucoma is documented for either eye; instead, use the appropriate stage-specific bilateral code.
• If laterality is not specified, query the provider. If only one eye is affected, use the appropriate unilateral code.
