Diabetes due to underlying condition w hypoglycemia w coma

This code signifies a patient experiencing a diabetic coma caused by severe hypoglycemia, where the diabetes itself is a secondary manifestation of another underlying medical condition. This is distinct from type 1 or type 2 diabetes, indicating the diabetes is a symptom of a primary disease process.

Apply this code when documentation clearly states a patient with diabetes due to an underlying condition (e.g., cystic fibrosis-related diabetes, pancreatectomy-induced diabetes) presents with a hypoglycemic coma. Physician notes must explicitly link the coma to hypoglycemia and confirm the underlying condition as the cause of the diabetes.

• Always sequence the underlying condition causing the diabetes first, followed by this code.
• Ensure documentation specifies "coma" and not just "hypoglycemia" or "altered mental status."
• Distinguish from codes for type 1 or type 2 diabetes with hypoglycemic coma (e.g., E10.641, E11.641).
