Diaper or napkin rash

This code represents an inflammatory skin condition affecting the diaper area, characterized by erythema, papules, and sometimes erosions. It is primarily caused by prolonged exposure to moisture, friction, and irritants found in urine and feces. The rash can range from mild redness to severe skin breakdown.

Use this code when documentation clearly indicates an irritant contact dermatitis confined to the diaper region, often seen in infants and incontinent adults. Supporting documentation should describe the location and appearance of the rash, and rule out other dermatological conditions.

• Differentiate from candidal diaper dermatitis, which requires a separate code (e.g., 112.1).
• Ensure documentation specifies the rash is due to irritation from diapers or napkins, not another underlying cause.
• Consider an additional code for any secondary bacterial infection if documented.
