Coding Tips

Clinical Significance

Drug or chemical induced diabetes mellitus without complications indicates that a medication or chemical has caused diabetes, but no end-organ damage or acute metabolic derangements are currently present. This may represent early-stage disease, well-controlled diabetes, or a patient who has not yet developed complications. Ongoing monitoring for the development of complications is essential, as the causative agent may continue to affect glycemic control.

Documentation Requirements

• ✓The causative drug or chemical must be identified and coded with appropriate external cause codes.
• ✓Documentation should explicitly state the absence of diabetic complications.
• ✓Current diabetes management including medications, most recent hemoglobin A1c, and monitoring plan should be recorded.
• ✓The clinical decision regarding whether to continue, modify, or discontinue the causative agent should be documented.
