Code Description

ICD-10 E09.641 is a billable code used to indicate a diagnosis of drug or chemical induced diabetes mellitus with hypoglycemia with coma.

Key Diagnostic Point:

E09.641 refers to diabetes mellitus that is induced by drugs or chemicals, characterized by episodes of hypoglycemia leading to coma. This condition typically arises in patients who are receiving pharmacological treatments that affect glucose metabolism, such as corticosteroids, antipsychotics, or certain chemotherapeutic agents. The hypoglycemic episodes can be severe and may result in loss of consciousness, necessitating immediate medical intervention. Management of this condition involves careful monitoring of blood glucose levels, adjustment of medication dosages, and potentially the use of glucose administration to counteract hypoglycemia. The presence of coma indicates a critical state that requires urgent care, often in an inpatient setting. Understanding the underlying cause of the diabetes, the specific drug or chemical involved, and the patient's overall health status is crucial for effective treatment and management.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Requires knowledge of drug-induced diabetes mechanisms.
  • Need for precise documentation of drug history.
  • Management of hypoglycemia and coma adds complexity.
  • Differentiation from other types of diabetes is necessary.

Audit Risk Factors

  • Inadequate documentation of drug history.
  • Failure to document the severity of hypoglycemia.
  • Lack of clarity on the relationship between drug use and diabetes onset.
  • Inconsistent coding of hypoglycemia episodes.
