When HealthPocket first investigated Medicaid acceptance in 2013, it found that only 43% of the healthcare providers examined were formally listed as accepting Medicaid.1 Since the original 2013 study, Medicaid enrollment has continued to rise as the Affordable Care Act has led many states to increase the income eligibility range for the program.2 Medicaid, along with the Child Health Insurance Program (CHIP), currently covers approximately 1-in-5 people in the United States.3 This year, the temporary increase4 in Medicaid payments to primary care physicians discontinues with only 15 states indicating that they intend to maintain the payment increase (fully or partially).5 The reduction in Medicaid reimbursement to primary care physicians has brought with it a concern that Medicaid acceptance, already low among healthcare providers, will drop further.
Given the size of the Medicaid program and its importance to America’s low-income population, HealthPocket repeated its examination of Medicaid acceptance using updated 2015 data for the same categories of healthcare providers examined in the original study.6 In both the 2013 study and the 2015 study, over a million healthcare provider records were analyzed with respect to Medicaid acceptance.
HealthPocket found that in 2015 only 34% of the healthcare providers examined were listed as accepting Medicaid insurance. This represents a 21% decrease from the listings of Medicaid acceptance found in the 2013 data for the same categories of healthcare providers.
Since both the 2013 analysis and 2015 analysis relied upon the same government data source and provider record parameters, the marked decline in Medicaid acceptance is significant. In particular, the data calls into question whether the temporary increase in Medicaid payments to primary care physicians effected any lasting improvements to Medicaid acceptance.
Given the number of people served by the Medicaid program, it surprises some people outside the healthcare field that Medicaid does not have wider acceptance among healthcare providers. A common explanation given for Medicaid lower acceptance is the program’s reimbursement rate to healthcare providers. Medicaid typically pays 61% of what Medicare pays for the same outpatient physician services.7 To make matters worse, the Medicare payment benchmark is already lower than payments for the same services from private insurers. It is estimated that Medicare typically pays 80% of what commercial health insurers pay.8 Consequently, in comparison to commercial health insurance from private insurance companies, Medicaid payments represent a reduction on a reduction.
There are additional factors beyond reimbursement rates that have also negatively affected Medicaid acceptance among healthcare providers. A 2013 study9 published in HealthAffairs included the following recommendations to increase Medicaid acceptance based on physician feedback captured in survey and focus group research:
The problem of limited Medicaid acceptance has been discussed for years. One of state governments’ responses to the problem is the use of managed care organizations to serve some portion of a state’s Medicaid population.10 However, as a 2014 Health & Human Services study noted, state standards regarding the ratio of primary care physicians to Medicaid managed care enrollees can vary widely (1-to-100 to 1-to-2,500) as do their methods for determining compliance with these standards.11 Consequently, Medicaid enrollees can face the prospect of long distances and/or long waits to access care under the program.12
Senator Tom Coburn observed, “Medicaid shows that access to a government health care program does not guarantee access to health care.”13 HealthPocket’s comparison of Medicaid acceptance listings from 2013 to 2015 illuminates an alarming trend for those dependent on Medicaid for their healthcare: a reduction in Medicaid acceptance occurring during a period of Medicaid enrollee expansion. How federal and state governments will reverse this trend remains to be seen. The temporary increase in Medicaid payments to primary care physicians from 2013 to 2014 does not appear to have produced a lasting increase in Medicaid acceptance and the expiration of this increase may contribute to further healthcare provider attrition from the Medicaid program. Consequently, a broader set of interventions may be necessary to make long-term improvements to Medicaid acceptance among healthcare providers.
Medicaid acceptance among healthcare providers was determined from National Provider Identifier (NPI) Registry records managed by the Centers for Medicare & Medicaid Services (CMS). Individual healthcare providers may only have a single NPI, which, in turn, is associated with their unique healthcare provider information including the taxonomy code indicating their service classification.
1,327,548 NPI records were examined for healthcare providers whose taxonomy code had their first three digits within the range 207 to 247. NPI data was collected on February 23, 2015.
All analysis assumes the accuracy of the underlying government data. While every effort was made towards to enhance data accuracy, HealthPocket makes no representation that every healthcare provider in the selected geographies were included in this study.
Percentages are rounded according to standard industry practices.

4 “To prepare the primary care workforce for the influx of new Medicaid-eligible patients established through the Affordable Care Act (ACA), this provision increases payment rates for certain primary care services to at least the level of Medicare in 2013 and 2014. The provision, often referred to as the Medicaid Primary Care Pay Parity program was included because primary care physicians, including internal medicine subspecialists who provide primary care, will be particularly affected by the Medicaid expansion since millions of new patients will enter the health care system and many will have complex health care needs.“ Taken from “Enhanced Medicaid Reimbursement Rates for Primary Care Services.” Unpublished work ©2014.
