Drug/chem diabetes w unsp diabetic rtnop w/o macular edema

This code signifies diabetes mellitus that has been caused by a drug or chemical agent, rather than being autoimmune (Type 1) or lifestyle-related (Type 2). The patient also presents with damage to the retina (retinopathy) as a complication of their diabetes, but the specific type of retinopathy is not documented, and there is no swelling in the macula.

Use this code when documentation clearly states drug- or chemical-induced diabetes and mentions diabetic retinopathy without specifying its proliferative or nonproliferative nature, and explicitly rules out macular edema. This is appropriate when the physician's assessment indicates a causal link between medication/chemical exposure and the onset of diabetes.

• Always sequence the drug or chemical causing the diabetes as an additional code, if known.
• Ensure documentation explicitly states "drug-induced" or "chemical-induced" diabetes; do not assume based on medication lists.
• If macular edema is present, or if the type of retinopathy is specified (e.g., proliferative, nonproliferative), a more specific code should be selected.
