What This Code Means

Diabetes caused by medications or chemicals that results in a skin condition characterized by inflammation and irritation.

Coding Tips

• •Document the specific drug or chemical causing the diabetes and link it to the dermatitis manifestation
• •Verify that the diabetes was induced by a known medication or chemical exposure, not type 1 or type 2 diabetes

Clinical Significance

Drug or chemical induced diabetes mellitus with diabetic dermatitis represents skin inflammation directly attributable to drug-induced diabetes. Diabetic skin conditions include necrobiosis lipoidica diabeticorum, granuloma annulare, diabetic dermopathy (shin spots), and other inflammatory dermatoses. These conditions serve as visible markers of diabetes and may indicate suboptimal glycemic control, warranting both dermatological treatment and diabetes management optimization.

Documentation Requirements

• ✓The causative drug or chemical must be identified and coded.
• ✓The specific dermatological manifestation should be described with clinical findings including location, morphology, and distribution.
• ✓Biopsy results, if obtained, should be referenced.
• ✓The causal connection between drug-induced diabetes and the skin condition must be documented.
