As you are aware, with each new year comes a new set of CPT/HCPCS codes.  After extensive review of the new 2024 codes by the Tennessee Hospital Association (THA) and the Tennessee Health Information Management Association (THIMA) professionals, we have determined which codes should be included or excluded from the ambulatory surgery definition beginning with the Q1-2024 discharge data which are due May 30, 2024. 

Please find the updated, change version, definition document here.  As you review the document you will see changes to the special inclusion and exclusion lists:  codes removed are highlighted in yellow and codes added are highlighted in peach.  You may also find the FINAL ambulatory surgery definition document here (this version does not include markups).  Below is a breakdown of changes for 2024 THA ambulatory surgery definition: 

• 23 codes were added, and 9 codes were removed to the general surgery range of 10021-69990 
• 6 codes were added to the select included CPT code list that are not within the general surgery range
• 5 codes were added to the select HCPCS Level II code list
• 26 codes were added, and 12 codes were removed the Category III code list 

This update will continue to be made each year with the release of new CPT/HCPCS codes. 

The THA ambulatory surgery definition document is made available, so you understand how HIDINet flags your outpatient records as an ambulatory surgery record.  Please continue to submit all your outpatient records as you currently do, and the system will continue to define and flag the ambulatory surgery records for you. 

You do not have to make any changes to the way you currently submit your data.  This is only an update to reflect the new 2024 CPT/HCPCS codes that are included or excluded in the ambulatory surgery definition.
