Oth diabetes mellitus with hypoglycemia with coma

This code signifies a form of diabetes mellitus, not otherwise classified as Type 1 or Type 2, that is complicated by a dangerously low blood glucose level leading to a state of unconsciousness. This represents a severe acute metabolic complication requiring immediate medical intervention.

Apply this code when documentation clearly indicates a patient with "other specified diabetes mellitus" experiencing a hypoglycemic coma. This typically occurs in patients whose diabetes is secondary to another condition, drug-induced, or unclassifiable as Type 1 or 2, and who present with altered mental status due to severe hypoglycemia.

• Ensure the physician explicitly documents "other specified diabetes mellitus" and "hypoglycemic coma."
• Distinguish from hypoglycemic coma in Type 1 (E10.641) or Type 2 (E11.641) diabetes.
• Always code the underlying cause of the "other specified diabetes mellitus" if known and documented.
