Diaper dermatitis

This code represents an inflammatory skin condition affecting the diaper area, characterized by erythema, scaling, and sometimes papules or vesicles. It is primarily caused by prolonged exposure to urine and feces, friction, and moisture, often exacerbated by bacterial or fungal overgrowth.

Use this code when documentation explicitly states "diaper rash," "diaper dermatitis," or similar terms describing inflammation confined to the skin covered by a diaper. This diagnosis is typically made clinically based on the characteristic appearance and location of the rash.

• Differentiate from other dermatitides affecting the groin or perineum that are not directly related to diaper use.
• Consider an additional code for secondary infections (e.g., candidiasis B37.2, bacterial infection L08.9) if documented.
• Ensure the documentation specifies the affected area as the "diaper area" to support this specific code.
