Drug/chem diab w diab mclr edma, resolved fol trtmt, r eye

This code signifies a patient diagnosed with diabetes mellitus that was caused by a drug or chemical agent, specifically presenting with macular edema in the right eye. Importantly, the macular edema has completely resolved following appropriate medical treatment.

Apply this code when documentation clearly indicates drug or chemical-induced diabetes and a history of right eye diabetic macular edema that is now resolved. This code is appropriate for follow-up encounters where the resolution of the macular edema is confirmed.

• Always sequence this code after the primary code for the drug or chemical causing the diabetes.
• Ensure documentation specifies "resolved" and not merely "improving" or "stable" for the macular edema.
• Verify laterality (right eye) is explicitly stated in the clinical record.
