Current Procedural Terminology
Coders review patient records, identify what information they need to abstract from the documentation, and then assign the correct code(s) to that information. This is a critical skill that you need to develop before you begin working as a medical coder.
The Current Procedural Terminology (CPT) code set is a medical code set maintained by the American Medical Association through the CPT Editorial Panel. The CPT code set (copyright protected by the AMA) describes medical, surgical, and diagnostic services and is designed to communicate uniform information about medical services and procedures among physicians, coders, patients, accreditation organizations, and payers for administrative, financial, and analytical purposes.
New editions are released each October. The current version is the CPT 2020. It is available in both a standard edition and a professional edition.
CPT coding is similar to ICD-9 and ICD-10 coding, except that it identifies the services rendered, rather than the diagnosis on the claim (ICD-10-CM was created for diagnostic coding- it took the place of Volume 3 of the ICD-9). The ICD code sets also contain procedure codes (ICD-10-PCS codes), but these are only used in the inpatient setting.
CPT is currently identified by the Centers for Medicare and Medicaid Services (CMS) as Level 1 of the Healthcare Common Procedure Coding System.
The Current Procedural Terminology (CPT) was developed by the American Medical Association (AMA).
CPT II codes describe clinical components usually included in evaluation and management or clinical services and are not associated with any relative value. Category II codes are reviewed by the Performance Measures Advisory Group (PMAG), an advisory body to the CPT Editorial Panel and the CPT/HCPAC Advisory Committee. The PMAG is composed of performance measurement experts representing the Agency for Healthcare Research and Quality (AHRQ), the American Medical Association (AMA), the Centers for Medicare and Medicaid Services (CMS), the Joint Commission on Accreditation of Healthcare Organizations (JCAHO), the National Committee for Quality Assurance (NCQA) and the Physician Consortium for Performance Improvement. The PMAG may seek additional expertise and/or input from other national health care organizations, as necessary, for the development of Category II codes. These may include national medical specialty societies, other national health care professional associations, accrediting bodies and federal regulatory agencies.
Category II codes make use of an alphabetical character as the 5th character in the string (i.e., 4 digits followed by the letter F). These digits are not intended to reflect the placement of the code in the regular (Category I) part of the CPT codebook. Appendix H in CPT section contains information about performance measurement exclusion of modifiers, measures, and the measures’ source(s). Currently there are 11 Category II codes. They are:
(0001F–0015F) Composite measures
(0500F–0584F) Patient management
(1000F–1505F) Patient history
(2000F–2060F) Physical examination
(3006F–3776F) Diagnostic/screening processes or results
(4000F–4563F) Therapeutic, preventive or other interventions
(5005F–5250F) Follow-up or other outcomes
(6005F–6150F) Patient safety
(7010F–7025F) Structural measures
(9001F–9007F) Non-measure claims-based reporting
CPT II codes are billed in the procedure code field, just as CPT Category I codes are billed. Because CPT II codes are not associated with any relative value, they are billed with a $0.00 billable charge amount.
Category III CPT Code(s) – Emerging technology (Category III codes: 0016T-0207T)
Major psychotherapy and psychiatry revisions
The CPT code revisions in 2013 were part of a periodic five-year review of codes. Some psychotherapy codes changed numbers, for example 90806 changed to 90834 for individual psychotherapy of a similar duration. Add-on codes were created for the complexity of communication about procedures. Family therapy and psychological testing codes were among those that were unchanged. 
Criticism of copyright
CPT is a registered trademark of the American Medical Association, and its largest single source of income. The AMA holds the copyright for the CPT coding system. However, in Practice Management v. American Medical Association the U.S. Court of Appeals for the Ninth Circuit held that while the AMA owned the copyright, it could not enjoin a competitor on the basis that the AMA had misused its copyright. Practice Management had argued that the publication of the CPT into federal regulation invalidated the copyright; the general debate around copyright and regulation access was revived in 2012 by a petition motivated by an Administrative Conference of the United States recommendation.
Despite the copyrighted nature of the CPT code sets, the use of the code is mandated by almost all health insurance payment and information systems, including the Centers for Medicare and Medicaid Services (CMS) and HIPAA, and the data for the code sets appears in the Federal Register. It is necessary for most users of the CPT code (principally providers of services) to pay license fees for access to the code.
