The American Medical Association (AMA) is the physician's powerful ally in patient care. Our efforts focus on four critical areas: representing physicians with a unified voice, removing obstacles that interfere with patient care, leading the charge in confronting public health crises and driving the future of medicine. For more information on the AMA, please visit ama-assn.org. For more than 50 years, the AMA has used its knowledge and resources to produce products and services for the health care industry that generate business efficiencies and empower physicians to provide high-quality care. The AMA product line includes titles on CPT(R), HCPCS and ICD-10 coding; reimbursement; practice management and Guides(R) impairment.
