Glaucoma secondary to drugs, right eye, moderate stage

This code signifies elevated intraocular pressure and optic nerve damage in the right eye, specifically caused by the use of certain medications. The glaucoma has progressed to a moderate stage, indicating a measurable degree of visual field loss and/or optic nerve damage.

Apply this code when documentation clearly states that glaucoma in the right eye is a direct consequence of drug therapy, and the severity is assessed as moderate. Supporting documentation should include a physician's diagnosis linking the glaucoma to drug use, visual field test results, and/or optic nerve head assessment confirming moderate damage.

• Ensure the documentation explicitly identifies the drug as the causative agent for the glaucoma.
• Verify the laterality (right eye) and the stage (moderate) are clearly documented.
• Do not confuse with primary open-angle glaucoma or other types of secondary glaucoma not related to drugs.
