Drug/chem diab with prolif diab rtnop with macular edema, bi

This code signifies diabetes mellitus that has been caused by a drug or chemical agent, presenting with advanced diabetic retinopathy characterized by new blood vessel growth (proliferative) and swelling in the macula of both eyes. It indicates a severe ocular complication of drug-induced diabetes affecting central vision bilaterally.

Apply this code when documentation clearly states a patient has diabetes mellitus attributed to a drug or chemical, and ophthalmological examination confirms bilateral proliferative diabetic retinopathy with macular edema. This diagnosis requires a definitive link between the medication/chemical exposure and the onset of diabetes.

• Ensure documentation explicitly links the diabetes to a drug or chemical cause, not just an exacerbation of pre-existing diabetes.
• Verify that both proliferative retinopathy and macular edema are present and affect both eyes.
• Sequence this code after the external cause code for the drug or chemical, if applicable and known.
