Drug/chem diab with mod nonp rtnop with macular edema, unsp

This code signifies diabetes mellitus that has been induced by a drug or chemical agent, complicated by moderate nonproliferative diabetic retinopathy. The retinopathy specifically includes the presence of macular edema, affecting an unspecified eye. This indicates a significant ocular complication of drug-induced diabetes.

Apply this code when documentation clearly states a patient has diabetes mellitus attributed to a drug or chemical, and an ophthalmologist or other qualified provider has diagnosed moderate nonproliferative diabetic retinopathy with macular edema. This code is appropriate when the affected eye is not specified in the medical record. Supporting documentation must include the etiology of the diabetes and the specific stage and complications of the retinopathy.

• Always sequence the drug or chemical causing the diabetes as an additional code, if known.
• Ensure the documentation specifies "moderate nonproliferative" and "macular edema"; otherwise, a less specific code may be required.
• If the affected eye (right or left) is documented, use the more specific code for that eye instead of this "unspecified eye" code.
