NAFC (National Association For Continence) says there are more than 1,400 free clinics in the U.S. Approximately 2 million people visited one of these clinics in the past year. Hospitals and private medical groups are often visited by those with the means. Federally Qualified Health Centers, or FQHCs, offer sliding scale rates for services to clients who are not able to pay for them due to their income, but no patient is denied health services because of their inability to pay.
