AMA's Medical Billing Code Dominance Criticized
A critic on social media argued that the American Medical Association's control over the CPT medical billing codes creates a monopoly that contributes to rising insurance premiums. The post suggests that the AMA's dominance in this area directly impacts the reimbursement rates set by insurers. This highlights an ongoing debate about the structure and costs within the U.S. healthcare system.
- The American Medical Association's (AMA) copyright over the Current Procedural Terminology (CPT) code set originated in 1966 to standardize terms for medical procedures. Its use became federally mandated for Medicare and Medicaid in the 1980s and was later cemented as the national standard under the Health Insurance Portability and Accountability Act (HIPAA). - The AMA generates a substantial portion of its revenue from licensing these CPT codes. In 2023, royalties from the CPT code set accounted for over $284 million of the AMA's $468 million in total revenue. - All entities that use CPT codes, including insurance companies, hospitals, and medical billing software vendors, are required to pay licensing fees to the AMA. For health plans, the licensing fee in 2025 was reported to be $0.24 per member per year, in addition to other potential fees for supplementary materials. - In late 2025, Senator Bill Cassidy, M.D. (R-LA), Chair of the Senate Health, Education, Labor, and Pensions (HELP) Committee, launched an inquiry into the AMA's control over the CPT codes. He has characterized the arrangement as a "government-backed monopoly" and is investigating whether the "exorbitant fees" contribute to rising healthcare costs. - CPT codes are fundamental to the insurance claims workflow, as they provide a universal language for what medical services were performed. A claim submitted by a provider uses a CPT code to detail the procedure and an ICD code to indicate the diagnosis, which allows the insurer to adjudicate and process the payment. - Critics argue that the AMA's monopoly over CPT codes creates a conflict of interest, as the organization that represents physicians also controls the codes integral to their reimbursement. Suggestions to increase transparency have included making the CPT Editorial Panel and RUC (Relative Value Update Committee) meetings fully public. - The Healthcare Common Procedure Coding System (HCPCS) is a related coding system, with Level I being identical to the AMA's CPT codes. However, Level II of HCPCS is managed by the Centers for Medicare & Medicaid Services (CMS) and covers items not included in CPT, such as medical supplies, ambulance services, and durable medical equipment. - Proponents for reform suggest that placing the CPT codes in the public domain could be achieved through executive action by the Secretary of Health and Human Services, which would eliminate the royalty structure. This would shift the management of the codes to a public body like the Centers for Medicare and Medicaid Services (CMS).
