Pigmentary glaucoma, bilateral, indeterminate stage

This code signifies a form of secondary open-angle glaucoma characterized by pigment dispersion, affecting both eyes, where the specific stage of the glaucoma (e.g., mild, moderate, severe) has not been determined or documented. It indicates elevated intraocular pressure and optic nerve damage due to pigment granules obstructing the trabecular meshwork in both eyes.

Use this code when documentation explicitly states "pigmentary glaucoma" affecting both eyes, and the physician has not specified the stage of the condition. This code is appropriate when the clinical picture confirms bilateral pigment dispersion syndrome leading to glaucoma, but further staging is pending or not yet established.

• Ensure documentation clearly specifies "bilateral" involvement and "indeterminate stage" for pigmentary glaucoma.
• Do not use this code if the stage of glaucoma is known; instead, select a more specific code indicating the stage (e.g., mild, moderate, severe).
• Code any associated pigment dispersion syndrome (H21.26-) separately if it is documented as a distinct finding.
