Background: Rural Health Clinics (RHCs)
(currently numbering about 4,100) have served patients
from underserved rural areas for nearly 40 years.
Although Medicaid is an important payer for RHCs, little
is known about Medicaid patients and the services
provided to them. This study describes the population who
used RHC services from four Medicaid states.
Methods: State data from North Carolina,
Georgia, California and Texas were drawn from the Centers
for Medicare and Medicaid Services' (CMS) Medicaid
Analytic Files Extract (MAX) data system. We used the
2009-2010 MAX Other Services (OT) claims data, which
includes all Medicaid claims that are not identified as
inpatient, long-term care, or prescription drug claims.
Key Findings: A substantial number of
RHC users in California, Georgia, North Carolina, and
Texas are identified as Medicaid enrollees, ranging from
approximately 100,000 to over 800,000 people per state.
Demographic characteristics vary substantially by state.
The percentage of RHC users who are dually enrolled in
Medicare and Medicaid ranges from 1% in Texas to 19% in
North Carolina. Fifty to 79% of the RHC user population
are coded as living in a rural area following the Federal
Office of Rural Health Policy definition. However, 20% of
the RHCs in these four states are not in areas defined as
This description of RHC users should assist policy makers
and researchers in understanding and planning for the
population who receives services from RHCs.
