Evaluating Medicaid Coverage for Over-the-Counter Treatments for Diaper Dermatitis.

Diaper dermatitis is a common dermatologic condition in infancy, frequently managed with over-the-counter (OTC) products. We conducted a cross-sectional review of Medicaid Preferred Drug Lists across 49 states and the District of Columbia to evaluate coverage of 14 commonly used OTC diaper dermatitis treatments. Coverage varied widely by state and product class, with therapeutic agents, such as topical antifungals, low potency corticosteroids, and antibiotics, more frequently covered than preventive barrier products, such as petrolatum and zinc oxide. These findings reveal significant state-level disparities in Medicaid coverage and highlight the potential access gaps for low-income families managing a common pediatric condition.
