Comprehensive physician compensation surveys indicate that the lowest-paid medical doctors are predominantly found in primary care and pediatric subspecialties. Medical specialties such as pediatrics, preventive medicine, pediatric endocrinology, and family medicine consistently report lower average annual earnings compared to surgical fields like neurosurgery, orthopedics, and cardiology, largely due to academic institutional settings, lower relative value unit (RVU) billing codes, and government or Medicaid insurance reimbursement structures.
