Centerstone Health Services is a Federally Qualified Health Center (FQHC), Look-alike. Under Prospective Payment System (PPS), FQHC Look-alikes receive higher cost-based reimbursement rates that enable them to provide low-cost health care to underserved communities.
The cost of prescription medications is a common barrier to health in low-income communities. FQHC Look-alikes qualify for Federal Drug Pricing Program discounts. These savings and higher reimbursement rates help us expand the services we offer.
Centerstone Health Services embraces the health and well-being for all people by providing comprehensive, accessible, quality health care regardless of income to promote wellness and restore health.
Centerstone Health Services inspires and builds healthy lives through superior care, collaboration, education and awareness that improves the overall health status of the community.
