      <Desc>Baystate Medical Practices, Inc. provides physician services, medical education and research programs to people in the community within its geographic location. BMP's policy is to provide care to any patient in need of medical care, regardless of the patient's ability to pay for such care. Dependent upon the patient's financial capability to pay, BMP may provide such care free of charge or at amounts below its normal charges. Because BMP does not pursue collection of amounts determined to qualify as charity care, they are not reported as revenue. In addition to the charity care provided to patients, BMP's physicians participate in many and varied ongoing community outreach initiatives in the areas of education, employment, safety and health. For example, the BMP physicians in the Department of Pediatrics, in collaboration with the Springfield School Department, staff six school-based clinics that enhance school health education programs, provide professional development courses for teachers and administrators and establish a school-to-work program.BMP has also taken a leadership role in strengthening the health of disadvantaged citizens in surrounding communities including specific focus on AIDS and HIV and by providing physician staffing for three community-based health centers through Baystate Medical Center.Part VI, Section A, Line 1b:Baystate Medical Practices, Inc. (BMP) is part of an integrated delivery system including not for profit community hospitals, which have community boards. BMP is a physician organization, which supports Baystate Health and its affiliates and is comprised primarily of BMP employees. This board structure has not changed significantly since the organization applied for exempt status.</Desc>
