Coding Classification Authorities
Specific organizations are recognized as the national authorities on coding classifications and advice. Classification changes and associated guideline development are the responsibility of the various medical code set maintenance organizations. Therefore, neither AHIMA nor CHIA may issue coding guidelines independently.
The ICD-9-CM and ICD-10-CM/PCS classification systems are maintained by the National Center for Health Statistics (NCHS) and the Centers for Medicare & Medicaid Services (CMS).
The Current Procedural Terminology (CPT) code set is maintained by the American Medical Association through the CPT Editorial Panel.
The Healthcare Common Procedure Coding System (HCPCS) is under the authority of CMS.
The American Hospital Association’s Central Office serves as the official U.S. Clearinghouse on medical coding for the proper use of the ICD-9-CM systems and Level I HCPCS (CPT-4 codes) for hospital providers and certain Level II HCPCS codes for hospitals, physicians and other health professionals.
The ICD-9-CM coding guidelines are clarified through unanimous agreement by the Cooperating Parties of the ICD-9-CM Coding Clinic. The Cooperating Parties are NCHS, CMS, AHIMA and the American Hospital Association (AHA). Therefore, neither AHIMA nor CHIA may issue coding guidelines independently. AHIMA and the other Cooperating Parties can only refer coders seeking official ICD-9-CM coding advice to the AHA.
