When to Use

Use S121 specifically for a repeat transabdominal vagotomy when a previous vagotomy has already been performed.
Select this code when the surgical approach is strictly transabdominal, distinguishing it from thoracic or other approaches.
Use this code for revision surgery where the primary intent is the re-interruption of vagal fibers following a failed or incomplete initial procedure.

Common Pitfalls

Billing S121 in conjunction with a hospital admission assessment; this is rejected unless the assessment qualifies as the 'major pre-operative visit' for the procedure.
Confusing S121 with S139; ensure the clinical documentation clearly supports the 'previous vagotomy' history required for the S121 fee.
Failing to document the specific anatomical findings of the previous vagotomy, which is essential for audit justification of the repeat procedure.

Billing Tips

Ensure that if the procedure is performed after hours, you append the appropriate E-code (E409 or E410) to the claim to capture the 50% or 75% premium.
If a surgical assistant is required, bill the assistant's service concurrently with the appropriate after-hours premium (E400B or E401B) to maximize the total claim value.
