Drug/chem diabetes mellitus w hypoglycemia w coma

This code signifies diabetes mellitus that has been caused by a drug or chemical agent, specifically presenting with a complication of hypoglycemia and a further complication of coma. This indicates a severe adverse reaction to a medication or chemical exposure resulting in dangerously low blood sugar levels leading to unconsciousness.

Use this code when documentation clearly states drug-induced diabetes mellitus, hypoglycemia, and a comatose state as a direct result. This typically occurs in patients receiving medications known to affect glucose metabolism, such as corticosteroids, or following toxic chemical exposure. Supporting documentation must explicitly link the diabetes, hypoglycemia, and coma to a specific drug or chemical.

• Always identify the specific drug or chemical causing the diabetes using an external cause code (T36-T65) in conjunction with this code.
• Do not use this code for type 1 or type 2 diabetes with hypoglycemia and coma, even if the patient is on medication; those have distinct codes.
• Ensure the documentation specifies "drug or chemical induced" diabetes, not just diabetes in a patient taking medication.
