E09.8

What This Code Means

This code describes diabetes that develops as a side effect of taking certain medications or being exposed to specific chemicals, when the exact complications are not specified or documented. It's used when a drug or chemical is known to have caused the diabetes, but the medical record doesn't detail what specific problems have resulted from it.

Coding Tips

• •Always identify and document the specific drug or chemical causing the diabetes - use an additional code from the Table of Drugs and Chemicals to specify the causative agent and whether it was accidental or intentional
• •If specific complications ARE documented (such as neuropathy, nephropathy, or retinopathy), use the more specific E09 subcategories (E09.2, E09.3, E09.4, etc.) rather than E09.8, as unspecified should only be used when complications are truly not specified

Clinical Significance

Drug or chemical induced diabetes mellitus with unspecified complications represents the least specific code for complicated drug-induced diabetes, indicating the provider has documented complications but their nature is not identified. This code signals a documentation gap that should be addressed through provider queries. Unspecified codes are increasingly scrutinized by payers and may not withstand audit review.

Documentation Requirements

• ✓The causative drug or chemical must be documented.
• ✓While this code accepts unspecified complications, best practice requires documenting all identifiable complications to support more specific coding.
• ✓The medical record should reflect attempts to identify the specific complications.
• ✓If the complication becomes known, the code must be updated.
