The American Medical Association (AMA) has officially released the Calendar Year (CY) 2023 Current Procedural Terminology (CPT®) code set

The 2023 updates include 102 new codes, 68 deleted codes, and 87 codes with revised long descriptions. The updates are effective beginning January 1, 2023. 

Evaluation and Management

The Evaluation and Management (E/M) section has one addition, 26 deletions, and 50 revisions for 2023. A new add-on code (99418) describes prolonged inpatient or observation E/M services. Many observation codes are deleted due to the consolidation of inpatient and observation E/M codes in CY 2023. The other deleted codes include domiciliary or rest home and prolonged service codes. 
The revisions include the following: 

  • Clarifying hospital E/M codes to include “inpatient or observation” care due to the consolidation of inpatient and observation codes in 2023. 
  • Replacing the wording describing a detailed or comprehensive history and examination with a “medically appropriate history and/or examination.” 
  • Changes to the total time to meet when using time for code selection. 
  • On hospital discharge day management codes, the words “on the date of the encounter” have been added for clarification. 
  • Office consultation codes have been revised to include “other outpatient” consultation services. 
  • An emergency department E/M code has been revised to include services that may not require the presence of a physician or other qualified healthcare professional. 
  • Home visit codes have been revised to include “residence” as a place of service. 
  • Minor clarifying word changes have been made to the prolonged outpatient E/M service add-on code. 
  • Interprofessional telephone/internet/EHR assessment and management consult service codes have been revised to include “other qualified health care professional” when referring to the consultant. 
  • Minor clarifying word changes have been made to the transitional care management service codes. 


Coding updates in the surgery section include the following systems: integumentary, musculoskeletal, respiratory, cardiovascular, digestive, urinary, male genital, and nervous.
