  2. The new code (90480) for reporting the administration of any COVID-19 vaccine for any patient.

Descriptor Revisions About Time: CPT Codes 2024

You’ll be happy to know that the changes made by CPT to the evaluation and management (E/M) codes and guidelines in the past few years are extensive. However, the E/M updates in CPT Codes 2024 are minimal, which may seem insignificant, but they still hold importance. 

Changes W.r.t. Time

According to the CPT Codes 2024 update, it has been announced that it will replace the time ranges for new and established office/outpatient E/M codes with a single total time amount. This total time amount will be the minimum number of minutes currently specified in the range for each code. The new wording in each code’s Descriptor states that this time “must be met or exceeded.”

For example, 99202 Office or another outpatient visit for evaluating and managing a new patient, which requires a medically appropriate history or examination and straightforward medical decision-making, has a current time range of 15-29 minutes

Beginning Jan. 1, 2024, the provider must meet or exceed 15 minutes of total service time before you can bill this code by time.

General Criteria for Category I and Category III of CPT Codes 2024

Following are the general criteria for Category I and Category III proposed by the American Medical Associaton according to their latest update guidelines: 

  • The Descriptor of the CPT 2024 code set should be understandable , unique, and specific to describe and distinguish the service procedure from existing procedures and services in CPT.
  • The structure guidelines, descriptors, and instructions remain compatible with existing editorial panel standards to maintain the CPT 2024 code set.
  • Note that the proposed descriptor structure for both services or procedures will be neither a fragmentation of an existing procedure or service nor currently reportable as a complete service by one or more existing codes, excluding unlisted codes. 

Staying up-to-date is pivotal in the constantly evolving world of procedures and services. That’s why new or revised codes are often necessary to ensure accuracy and efficiency. Don’t let outdated codes slow you down – stay proactive and adaptable by implementing the latest codes.

CPT code descriptors are not used to report extraordinary circumstances related to the performance of a procedure or service already described in the CPT code set. A procedure or service must meet specific category criteria to qualify for a CPT code.

According to AMA, Category I CPT codes are used to report procedures and services that are

  • Performed frequently by many physicians or other healthcare professionals across the United States
  • Consistent with current medical practice
  • Clinically efficacious and documented in the literature
  • Category I CPT codes are not used to report extraordinary circumstances related to the performance of a procedure or service already described in the CPT code set.
