What This Code Means

Coding Tips

Clinical Significance

Drug or chemical induced diabetes mellitus with hypoglycemia without coma represents episodes of dangerously low blood sugar in patients with drug-induced diabetes that do not progress to loss of consciousness. Recurrent hypoglycemia is a significant barrier to optimal glycemic management and carries risks including cognitive impairment, falls, cardiac arrhythmias, and development of hypoglycemia unawareness. Each episode necessitates medication adjustment and patient education.

Documentation Requirements

• ✓The causative drug or chemical must be identified.
• ✓Blood glucose levels during hypoglycemic episodes should be documented.
• ✓Symptoms experienced (tremor, sweating, confusion, palpitations) and self-treatment measures must be recorded.
• ✓The frequency of hypoglycemic episodes and any pattern (time of day, relation to meals/medications) should be noted.
• ✓Documentation must confirm the patient did not lose consciousness.
