There is guidance about the many CPT codes describing the administration of the influenza vaccine on the College’s website in the FAQ section. Code according to the product you are using to accurately bill for flu vaccine and its administration.

2024 CPT Changes (effective Jan. 1, 2024)

Revisions to the 2024 CPT code set clarify the reporting of evaluation and management (E/M) services, in an effort to decrease providers’ administrative burden of documentation. The revisions include:

  • The removal of time ranges from office or other outpatient visit codes (99202-99205, 99212-99215) and align the format with other E/M codes.
  • The “substantive portion” of a split/shared E/M visit is defined by describing the scenario in which a physician and a nonphysician practitioner work jointly to furnish all the work related to the visit.
  • Guidelines for reporting hospital inpatient or observation care services and admission and discharge services for the use of codes 99234-99236 – when the patient’s stay crosses over two calendar dates.

Telemedicine: There is a new E/M subsection with new guidelines for E/M telemedicine services performed via audio-visual and audio-only mechanisms. The new codes will align with the current E/M office or other outpatient services code structure (i.e., using time or medical decision making) with separate codes for new and established patient encounters. In addition, a virtual check-in code will be added that could be used to determine whether a patient needs a face-to-face visit. Codes 99441, 99442, and 99443 will be deleted.

Unlisted Service Codes: There will be revisions to the reporting guidelines for unlisted service codes for various sections of the CPT 2024 code set to reflect appropriate use of unlisted codes when reporting with other services.

RSV Immunizations: Five new CPT codes have been created to report product-specific RSV immunizations (90380, 90381, 90683, 90679, and 90678) for better tracking, reporting and analysis that supports data-driven planning and allocation.

The Advocacy Council urges its members to review and consider how the new code changes may impact their practices.
