Pigmentary glaucoma, bilateral, stage unspecified

This code signifies a form of secondary open-angle glaucoma characterized by the dispersion of pigment granules from the iris, which then deposit in other structures of the eye, particularly the trabecular meshwork, obstructing aqueous humor outflow. This specific code indicates that both eyes are affected, and the severity or stage of the glaucoma has not been determined or documented.

Apply this code when documentation confirms pigmentary glaucoma affecting both eyes, but the physician has not specified a stage (e.g., mild, moderate, severe). This is appropriate for initial diagnoses or when follow-up documentation lacks staging information for bilateral pigmentary glaucoma.

• Ensure documentation explicitly states "bilateral" involvement; otherwise, use a unilateral code.
• Avoid using this code if a specific stage of pigmentary glaucoma (e.g., mild, moderate, severe) is documented for either eye; instead, select the appropriate staged code.
• Always sequence this code after any underlying cause or associated systemic conditions, if applicable.
