Code Description

ICD-10 E09.649 is a billable code used to indicate a diagnosis of drug or chemical induced diabetes mellitus with hypoglycemia without coma.

Key Diagnostic Point:

E09.649 refers to diabetes mellitus that is induced by drugs or chemicals, characterized by episodes of hypoglycemia without the presence of coma. This condition typically arises from the use of certain medications, such as glucocorticoids, antipsychotics, or other agents that can disrupt normal glucose metabolism. Patients may experience symptoms such as sweating, tremors, confusion, and palpitations due to low blood sugar levels. Management of this condition involves careful monitoring of blood glucose levels, adjusting medication dosages, and educating patients about recognizing and treating hypoglycemic episodes. The presence of hypoglycemia complicates the management of diabetes, as it requires balancing the need for glycemic control with the risk of low blood sugar. Regular monitoring of HbA1c levels is essential to assess long-term glycemic control, while insulin management may be necessary for some patients. Understanding the underlying cause of drug-induced diabetes is crucial for effective treatment and prevention of complications.

Medical Specialties

Endocrinology

Documentation Requirements

Comprehensive medication history, detailed management plans, and regular monitoring of HbA1c levels.

Common Clinical Scenarios

Patients presenting with new-onset diabetes after starting a new medication, or those experiencing recurrent hypoglycemic episodes.

Billing Considerations

Endocrinologists must ensure that the cause of diabetes is accurately documented to avoid misclassification.

Primary Care

Documentation Requirements

Thorough patient history, including medication review and lifestyle factors.

Common Clinical Scenarios

Routine follow-ups for patients on medications known to induce diabetes, or those with unexplained hypoglycemia.

Billing Considerations

Primary care providers should be vigilant in monitoring for signs of hypoglycemia and adjusting treatment accordingly.
