- How often do Medicaid enrollees visit dermatologists in comparison to patients who are uninsured or have private insurance?
- Are Medicaid patients more likely to receive care for skin-related conditions from primary care physicians or dermatologists?
Access to dermatologists is an ongoing concern for Medicaid enrollees. Understanding current use is a key step toward designing and implementing policies to improve access.
We sought to quantify how often Medicaid enrollees visit dermatologists and receive treatment for skin-related conditions compared with patients with other coverage or without health insurance.
We conducted a retrospective cross-sectional analysis of multiyear federal survey data (Medical Expenditure Panel Survey). The sample included Medical Expenditure Panel Survey respondents younger than 65 years from 2008 to 2012.
In unadjusted comparisons, we found that 1.4% of Medicaid enrollees had an ambulatory visit to a dermatologist annually, compared with 1.2% of uninsured individuals and 5.5% of individuals with private coverage. In adjusted models, we found that health insurance source, age, sex, race/ethnicity, and geography are associated with the likelihood of having visits to a dermatologist. Compared with individuals with private coverage, Medicaid enrollees are less likely to receive a diagnosis for a skin condition by any provider and are less than half as likely to have skin-related diagnoses made by dermatologists.
We have relatively few Medical Expenditure Panel Survey respondents for a subset of specific diagnoses.
Our findings emphasize the need for efforts to reduce disparities in access to dermatologists.
- Medicaid enrollees are less likely to receive care from a dermatologist than people with private insurance, signaling that Medicaid patients face barriers to accessing these specialists.
- Differences in receipt of care among Medicaid enrollees and privately insured people were not associated with sociodemographics or illness burden.
- Rates of dermatologist use were similar among Medicaid enrollees and people with no health insurance.
- Skin-related condition diagnosis among Medicaid enrollees was more likely to come from primary care doctors than dermatologists.
- To increase Medicaid enrollees' access to dermatologists, states could require managed care plans to maintain more extensive networks of dermatologists, increase dermatologists' payment rates, or introduce teledermatology to enable distant consultations.
