Glaucoma secondary to drugs, unspecified eye, moderate stage

This code signifies glaucoma that has developed as an adverse effect of medication, affecting an unspecified eye, and has progressed to a moderate stage. This condition involves elevated intraocular pressure leading to optic nerve damage and visual field loss, directly attributable to drug use.

Apply this code when documentation clearly states a diagnosis of drug-induced glaucoma, without specifying laterality, and the severity is explicitly noted as moderate. This typically occurs when a patient's medication history includes drugs known to cause glaucoma (e.g., corticosteroids) and there's a confirmed causal link.

• Ensure the medical record explicitly links the glaucoma to a specific drug and specifies the stage as "moderate."
• Do not use this code if the laterality (right or left eye) is documented; instead, select the appropriate laterality-specific code.
• Always code the adverse effect of the drug (T36-T50 with 5th or 6th character 5) as a secondary diagnosis to fully capture the clinical picture.
