88.9% of primary care physicians said they are accepting new patients, based on 2015 data from the National Electronic Health Records Survey. However, the survey found there are differences in acceptance rates based on the patient’s expected form of payment:
- 94.2% of physicians accepted patients with private insurance
- 77.4% of physicians accepted patients with Medicare
- 71.6% of physicians accepted patients with Medicaid
Why is there such a big difference? They key reason is physician reimbursement rates.
Daniel Polsky, PhD, MPP, an economist at the Wharton School at the University of Pennsylvania, ran an experiment in which field workers tried to get appointments, half posing as Medicaid recipients, and half posing as clients with private insurance. They did the experiment in 2012, before the ACA increased Medicaid payments and again in 2014, right after the pay boost took effect. The pay increase caused about an 8% increase in the number of people who could get appointments.
This is one clear example where having health insurance does not guarantee access to care.
