Code Description

ICD-10 E09.49 is a billable code used to indicate a diagnosis of drug or chemical induced diabetes mellitus with neurological complications with other diabetic neurological complication.

Key Diagnostic Point:

E09.49 refers to diabetes mellitus that is induced by drugs or chemicals, which can lead to various complications, particularly neurological ones. This condition arises when certain medications, such as corticosteroids or antipsychotics, disrupt normal glucose metabolism, resulting in hyperglycemia and subsequent diabetes. Neurological complications may include diabetic neuropathy, which manifests as pain, tingling, or loss of sensation in the extremities, and can significantly impact a patient's quality of life. The presence of other diabetic neurological complications may further complicate management, necessitating a comprehensive treatment approach that includes monitoring HbA1c levels, managing insulin therapy, and addressing the specific neurological symptoms. Effective management is crucial to prevent progression of complications and to maintain optimal glycemic control.
