Drug/chem diabetes mellitus w oth circulatory complications

This code signifies diabetes mellitus that has been caused by a drug or chemical agent, and the patient is also experiencing circulatory complications directly related to this drug-induced diabetes. These circulatory complications can include conditions affecting the heart, blood vessels, or blood flow. It differentiates from other forms of diabetes by its iatrogenic or toxic etiology.

Apply this code when documentation clearly states diabetes mellitus is a direct consequence of medication or chemical exposure, and the patient presents with associated circulatory issues. Examples include drug-induced diabetes leading to peripheral vascular disease or diabetic cardiomyopathy. Physician documentation must explicitly link the drug/chemical to the diabetes and the diabetes to the circulatory complication.

• Ensure the documentation specifies the drug or chemical causing the diabetes, if known, and the specific circulatory complication.
• Do not use this code for diabetes caused by therapeutic drug use for pre-existing diabetes (e.g., insulin).
• Sequence this code after any codes identifying the specific drug or chemical causing the adverse effect, if applicable.
