Drug/chem diab with severe nonp rtnop with mclr edema, unsp

This code signifies diabetes mellitus caused by medication or chemical exposure, specifically presenting with severe nonproliferative diabetic retinopathy and macular edema. The retinopathy indicates significant damage to the retinal blood vessels without new vessel growth, and the macular edema points to fluid leakage in the central part of the retina, impacting vision.

Apply this code when documentation clearly states drug or chemical-induced diabetes with severe nonproliferative retinopathy and macular edema, and the affected eye is not specified. Supporting documentation would include physician notes detailing the etiology of the diabetes, ophthalmological reports confirming the specific retinopathy stage, and the presence of macular edema.

• Ensure the documentation explicitly links the diabetes to drug or chemical induction, not type 1 or type 2.
• Verify the retinopathy is classified as "severe nonproliferative" and "with macular edema"; do not use for mild, moderate, or proliferative stages.
• Only use this code when the affected eye (left, right, or bilateral) is not specified in the medical record.
