Code Description

ICD-10 E09.64 is a billable code used to indicate a diagnosis of drug or chemical induced diabetes mellitus with hypoglycemia.

Key Diagnostic Point:

Drug or chemical induced diabetes mellitus with hypoglycemia refers to a form of diabetes that arises as a direct consequence of pharmacological agents or toxic substances. This condition is characterized by the presence of hyperglycemia due to the impairment of insulin secretion or action, alongside episodes of hypoglycemia, which can occur due to the effects of the inducing agent. Common drugs that may lead to this condition include glucocorticoids, thiazide diuretics, and certain antipsychotics. Patients may present with symptoms such as increased thirst, frequent urination, fatigue, and in severe cases, confusion or loss of consciousness due to hypoglycemia. Management typically involves careful monitoring of blood glucose levels, adjusting medication regimens, and providing education on recognizing and treating hypoglycemic episodes. The HbA1c levels in these patients may vary depending on the degree of glycemic control achieved and the presence of other underlying conditions. Insulin management may be necessary, particularly in cases where oral hypoglycemic agents are ineffective or contraindicated. It is crucial for healthcare providers to differentiate this condition from other types of diabetes to ensure appropriate treatment and management.
