Glaucoma secondary to drugs, right eye, indeterminate stage

This code signifies elevated intraocular pressure and optic nerve damage in the right eye, specifically caused by the use of certain medications. The stage of the glaucoma, indicating the severity of vision loss or field defects, cannot be definitively determined from the available clinical documentation.

Apply this code when a patient presents with glaucoma in the right eye, and the medical record clearly links its etiology to drug therapy. This is appropriate when the ophthalmologist or optometrist has not yet established a specific stage (e.g., mild, moderate, severe, or end-stage) for the condition.

• Ensure documentation explicitly states "right eye" and "indeterminate stage" for accurate coding.
• Always identify the specific drug causing the glaucoma with an additional code from T36-T50, if known and documented.
• Do not use this code if the stage of glaucoma is clearly documented (e.g., mild, moderate, severe); instead, select the appropriate stage-specific code.
