Answer: Yes, the CPT^® 2026 code book adds two new gastroenterology procedure codes in the new year. The new codes are as follows:

• 91124 (Rectal sensation, tone, and compliance study (eg, barostat))
• 91125 (Anorectal manometry, with rectal sensation and rectal balloon expulsion test, when performed)

These codes will replace 91120 (Rectal sensation, tone, and compliance test (ie, response to graded balloon distention)) and 91122 (Anorectal manometry) in 2026. The AMA and Specialty Society Relative Value Scale (RVS) Update Committee (RUC) Relativity Assessment Workgroup (RAW) “identified codes 91120 and 91122 as performed by the same physician on the same date of service 75 percent or more of the time,” according to CPT^® Assistant, Volume 35, Issue 11.

The CPT^® Assistant article adds that codes 91124 and 91125 “and their related parenthetical notes aligns with current clinical practice and prevents misreporting of these tests.”

Parenthetical notes under 91124 and 91125 instruct you to use these codes instead of 91120 and 91122, and the notes also state that the previous codes have been deleted.
