Specialty Physicians Advancing Rural Care Act or the SPARC Act This bill establishes student loan repayment programs to support the provision of specialty medical care in rural areas. The Health Resources and Services Administration (HRSA) must carry out such a program for certain specialty medicine physicians who provide care in rural communities with shortages of such physicians. Physicians must agree to a period of obligated service and, for each year of such service, HRSA must pay one-sixth of the principal payment and interest on eligible loans up to a maximum cap of $250,000. Additionally, HRSA may carry out a similar loan repayment program for nonphysician specialty health care providers.
