Code Description

ICD-10 E09.620 is a billable code used to indicate a diagnosis of drug or chemical induced diabetes mellitus with diabetic dermatitis.

Key Diagnostic Point:

E09.620 refers to diabetes mellitus that is induced by drugs or chemicals, specifically presenting with diabetic dermatitis. This condition arises when certain medications or chemical exposures lead to insulin resistance or impaired insulin secretion, resulting in elevated blood glucose levels. Common drugs associated with this condition include glucocorticoids, antipsychotics, and certain chemotherapy agents. Diabetic dermatitis manifests as skin changes, including dryness, itching, and lesions, often exacerbated by poor glycemic control. Management of this condition involves addressing the underlying drug exposure, optimizing blood glucose levels, and treating the dermatitis. Regular monitoring of HbA1c levels is crucial to assess long-term glycemic control, with target levels typically below 7% for most adults. Insulin therapy may be required if oral hypoglycemics are ineffective, particularly in cases of significant insulin resistance. Complications of drug-induced diabetes can include cardiovascular disease, neuropathy, and retinopathy, necessitating a comprehensive approach to patient care.
