The Current Procedural Terminology or commonly called as CPT is mostly used in medical billing, when filing claims. CPT codes are mainly used in clinics, as prescribed by American Medical Association or AMA to describe medical tests, various surgeries, evaluations, and any other medical procedure performed by a registered healthcare provider on a patient. Keeping in mind that the CPT code set is large, and includes the codes for thousands upon thousands of medical procedures.
What are CPT® Codes and Their Utilization in Medical Billing?
The Current Procedural Terminology (CPT®) codes provide a standardized language for healthcare professionals to code medical services and procedures. This uniformity enhances reporting, accuracy, and efficiency in medical practices.
Administrative Functions
CPT codes are essential for administrative management, playing a key role in claims processing and the establishment of guidelines for medical care review.
Widespread Acceptance
CPT terminology is recognized as the most widely used medical nomenclature in the United States. It is utilized for reporting a variety of services, including medical, surgical, radiology, laboratory, anesthesiology, genomic sequencing, and evaluation and management (E/M) services across public and private health insurance programs.
Development and Management
The creation and oversight of the CPT code set is governed by a rigorous and transparent process led by the CPT® Editorial Panel. Established over 50 years ago, this process convened by the AMA ensures that codes are clinically valid and are regularly updated to accurately reflect advancements in clinical practice and medical innovation.
Step-By-Step Guide to Create a New CPT Code

Step 1: Initial Review by AMA Staff
The AMA staff first assesses whether the request for a new code is indeed a new issue. If the request has already been evaluated, the applicant will be informed of the prior decision. If the request introduces significant new information, it advances to the next step.
Step 2: Evaluation by the CPT Advisory Committee
Next, the application is sent to the CPT Advisory Committee for detailed evaluation and feedback. AMA staff allocate a minimum of three months to compile and distribute all submitted materials for review. The process concludes when all necessary comments from CPT Advisors are received.
Step 3: Presentation to the CPT Editorial Panel
The 17-member CPT Editorial Panel convenes three times a year to review applications, addressing around 350 major topics annually. Prior to each meeting, AMA staff prepare an agenda that includes the application and CPT Advisor feedback, ensuring panel members have adequate time to consult with experts.
Step 4: Decision-Making by the CPT Editorial Panel
During the panel meeting, members vote on the application and classify the new code as either Category I or Category III. The panel may choose from four outcomes:
- Approve a new or revised code for inclusion in the upcoming CPT volume.
- Refer the application to a workgroup for further study.
- Postpone the decision for future meetings.
- Reject the request outright.
Step 5: Notification of the Panel’s Decision
Following the panel’s decision, the AMA staff informs the applicant. If the outcome is unfavorable, applicants can request a reconsideration of the decision, with details available on the AMA/CPT website.
Step 6: Referral to the RUC for Value Assessment
Once the CPT Editorial Panel approves the new or revised codes, the codes are forwarded to the AMA/Specialty Society Relative Value Update Committee (RUC). The RUC conducts surveys among qualified healthcare professionals to assess the work involved in the service or procedure, which informs relative value recommendations.
Step 7: Implementation of the New CPT Code
The new Category I service and procedure codes become effective annually on January 1, with the updated CPT book released in the fall. Category II codes are introduced quarterly, effective three months post-release, while Category III codes are rolled out semi-annually, effective six months after their announcement.

Conclusion
While the Current Terminology Procedures or CPT are not just ordinary medical codes approved by the American Medical Association (or AMA), there is whole science behind it. These are not just organized and structured by medical specialists but also approved by a committee. When a new CPT code is to be approved by a medical association, there has to be certain criteria in shaping a new code.
The main purpose of having a code in a procedure is to hide it from the general public and to give privacy and secrecy to ones suffering from any particular disease to eliminate all sorts of racism or hatred that a patient could potentially face. CPT codes are mainly in order but not every person could read them or rather understand them. Hence, only a specific set of procedures are studied by professionals belonging to, let’s say orthopedics and gynecologists will remember the codes that are necessary for them to carry out procedures.
