Pigmentary glaucoma, unspecified eye, moderate stage

This code signifies a form of secondary open-angle glaucoma where pigment granules from the iris are deposited in the trabecular meshwork, obstructing aqueous humor outflow. This specific code indicates the condition affects an unspecified eye and has progressed to a moderate stage of severity.

Use this code when documentation confirms a diagnosis of pigmentary glaucoma without specifying laterality (e.g., "pigmentary glaucoma, OU" or "pigmentary glaucoma, unspecified eye") and the physician explicitly states the disease is at a moderate stage. Supporting documentation typically includes visual field defects, optic nerve damage, and intraocular pressure readings consistent with moderate glaucoma.

• Ensure the medical record clearly specifies "moderate stage" for the unspecified eye; otherwise, an unspecified stage code (H40.1390) or mild/severe stage codes should be used.
• If laterality is documented (right or left eye), use the more specific codes H40.1312 (right eye) or H40.1322 (left eye).
• Always sequence glaucoma codes based on the type and stage, and consider any associated conditions or causes.
