We assessed provider directory accuracy and timely access in Maryland’s Medicaid managed care program, using annual surveys from the annual random and representative provider surveys conducted on behalf of the Maryland Department of Health for 2018 and 2019. Based on 3,262 calls to 2,002 providers in 2018 and 2,739 calls to 2,033 providers in 2019, we found that provider directories are highly inaccurate. Insurance coverage could only be verified for 46% of the listed providers in 2018 and 56% of the listed providers in 2019. Among providers whose insurance participation was verified, beneficiaries were able to schedule timely general care appointments in 90% of verified providers in 2018 and 85% of verified providers in 2019; slightly more than 70% of appointments were scheduled on the first call. The success rate for urgent care appointments was lower but improved substantially once alternative providers were accounted for. Even for verified providers, timely access standards were often not met, particularly for general care. We also note the substantial variation across managed care organizations and across years. Our findings raise concerns from both an enrollee as well as a broader policy perspective. More oversight and enforcement are necessary to guarantee access to care.
