Glaucoma secondary to drugs, unspecified eye, mild stage

This code signifies elevated intraocular pressure and optic nerve damage resulting from medication use, affecting an unspecified eye, and presenting in its earliest stage of severity. It indicates a form of secondary glaucoma where pharmaceutical agents are the causative factor.

Apply this code when documentation clearly links glaucoma development to a prescribed or illicit drug, and the laterality of the affected eye is not specified. Use when the physician explicitly states "mild stage" or equivalent terminology for the glaucoma's severity.

• Ensure the medical record explicitly states a drug as the etiology for the glaucoma.
• Do not use if the laterality (right, left, bilateral) is documented; instead, select a more specific code.
• Confirm the stage of glaucoma is documented as "mild" to support this specific code.
