What This Code Means

Diabetes caused by medications or chemicals that damages blood vessels in the legs and feet, resulting in tissue death and gangrene.

Coding Tips

•Document the extent and location of gangrene (toe, foot, leg, etc.)
•This is a more severe condition than E09.51; ensure gangrene is documented before coding

Clinical Significance

Drug or chemical induced diabetes mellitus with diabetic peripheral angiopathy with gangrene represents the most severe manifestation of diabetic macrovascular disease, where inadequate blood supply has caused tissue death. This is a limb-threatening and potentially life-threatening condition frequently requiring emergent surgical intervention including debridement or amputation. Gangrene in diabetic patients carries high morbidity with significant infection risk and prolonged hospitalization.

Documentation Requirements

✓The causative drug or chemical must be documented.
✓The extent, location, and type of gangrene (dry vs.
✓wet) must be described.
✓Vascular studies documenting arterial insufficiency should be referenced.
✓The underlying peripheral angiopathy and its relationship to drug-induced diabetes must be established.
✓Surgical planning documentation and wound care assessments are essential.

Commonly Confused Codes

E09.51 (without gangrene) is used when tissue death has not occurred.I96 (gangrene, not elsewhere classified) should not replace this combination code.E09.621 (foot ulcer) represents a less severe wound complication.L97 series (non-pressure chronic ulcer) may be coded additionally for ulcer staging.
