Glaucoma secondary to drugs, right eye, mild stage

This code signifies elevated intraocular pressure and optic nerve damage in the right eye, specifically caused by the use of certain medications. The condition is in its early stages, indicating minimal vision loss or optic nerve damage.

Apply this code when a patient presents with drug-induced glaucoma affecting the right eye, and clinical assessment confirms a mild stage of the disease. Documentation should clearly state the causative drug, the affected eye, and the mild severity of the glaucoma.

• Ensure documentation specifies the laterality (right eye) and the mild stage of glaucoma.
• Always code the adverse effect of the drug (T36-T50 with 5th or 6th character 5) as a secondary diagnosis.
• Distinguish from primary open-angle glaucoma (H40.1X) or other secondary glaucomas not drug-induced.
