What 49329 covers
Code 49329 identifies a laparoscopic abdominal operation involving the peritoneum or omentum when no more specific CPT laparoscopic procedure code describes the work. The surgeon uses a laparoscope and operative instruments to perform the documented procedure. General surgeons and other surgeons performing abdominal procedures may report it in a surgical setting. The operative note should identify the target anatomy, laparoscopic technique, purpose, and work completed, distinguishing the operation from diagnostic laparoscopy, biopsy, aspiration, or a named therapeutic procedure.
Medicare assigns this CPT code physician fee schedule status C: CMS publishes no national payment, and the Medicare Administrative Contractor prices each claim. The contractor also sets the global period. CMS's multiple-procedure reduction applies when other procedures are performed in the same session. For a bilateral service, modifier 50 is used under CMS's bilateral pricing rule. Documentation should explain why the operation is unlisted and support review of the claim.

49329 billing questions
When should 49329 be used instead of a listed laparoscopic code?
Use 49329 when no specific laparoscopic CPT code accurately describes the abdominal operation. If a listed code names the procedure performed, report that code instead.
How does 49329 differ from 49320?
49320 describes diagnostic laparoscopy. Use 49329 for an operation that is not represented by a more specific listed laparoscopic code.
What documentation supports a 49329 claim?
The operative note should describe the anatomy treated, laparoscopic approach, purpose, and work performed. It should make clear why a named laparoscopic procedure code does not describe the operation.
How does Medicare set payment for 49329?
Status C means CMS publishes no national payment; the Medicare Administrative Contractor prices each claim. The contractor also sets the global period.
How are bilateral and same-session procedures treated?
For bilateral reporting, modifier 50 is paid at 150% under CMS's rule. In the same session, the highest-valued procedure is paid in full and other procedures are paid at 50% under the multiple-procedure reduction.
