Type 2 diabetes mellitus with hypoglycemia without coma

This code signifies a diagnosis of Type 2 diabetes mellitus where the patient experiences episodes of abnormally low blood glucose levels (hypoglycemia) but remains conscious and responsive. It indicates a complication of diabetes management without the most severe neurological sequelae of profound hypoglycemia.

Apply this code when documentation clearly states Type 2 diabetes and a diagnosis of hypoglycemia, specifically noting the absence of coma. This is common in patients who may be on insulin or oral hypoglycemic agents and experience symptomatic low blood sugar that they are able to self-manage or that resolves with intervention without loss of consciousness.

• Always ensure the documentation explicitly states "without coma" or similar language to differentiate from codes indicating hypoglycemic coma.
• Code an additional external cause code (e.g., T38.3X6A for underdosing of insulin) if the hypoglycemia is drug-induced and the specific drug is known.
• Do not use this code if the patient has Type 1 diabetes; refer to the E10 category for Type 1 diabetic complications.
