Patient presents with moisture-associated skin damage (MASD), also known as incontinence-associated dermatitis (IAD), consistent with prolonged exposure to urine or stool.  Assessment reveals erythema, maceration, and denudation in the perineal region, extending to the buttocks and upper thighs.  The affected skin is moist and tender to the touch, with no evidence of purulent drainage or deep tissue involvement.  Differential diagnosis includes candidiasis, intertrigo, and pressure injury.  Based on clinical presentation and patient history of urinary incontinence, the diagnosis of MASD is confirmed.  Plan of care includes frequent skin cleansing with a pH-balanced cleanser, application of a skin barrier cream or ointment containing dimethicone or zinc oxide, and implementation of a moisture management strategy including absorbent products and frequent linen changes. Patient education provided regarding proper skin care, incontinence management, and the importance of regular monitoring for changes in skin condition.  ICD-10 code L22 will be used for billing purposes.  Continued assessment and adjustments to the treatment plan will be made as needed.
