is a health clinic that is contracted by HCFA to provide services to underserved populations. RHCs are reimbursed at a slightly higher level than the normal Medicare allowable. Usually clinics in outlying rural areas where the government needs to encourage practitioners to have clinics, although some "rural" clinics are located in poorer parts of inner cities. RHCs are given a special status and when they bill particular procedures with QB (rural) or QU (urban) modifiers, they will get the higher rate. RHCs usually have to submit claims on a UB-92.
