What 49900 covers

billing code 49900 describes operative reclosure of an abdominal incision when the abdominal wall has separated, including cases with evisceration. A surgeon typically performs the repair in an operating room, often after a patient returns following recent abdominal surgery. The operative report should identify the wound disruption and describe the repair of the abdominal wall; routine dressing care or superficial skin closure alone does not establish this service.

Report 49900 when the surgeon repairs the disrupted abdominal wall, not when the procedure is an incisional hernia repair. The code has a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

49900 billing questions

When should 49900 be chosen instead of an abdominal hernia repair code?

Use 49900 for operative repair of a disrupted abdominal incision, such as fascial separation or evisceration. Use a hernia repair code when the operative service repairs a hernia.

Can 49900 be reported with 49002?

49002 describes reopening a recent laparotomy, while 49900 describes repair of the disrupted abdominal wall. Both may be relevant when the surgeon reopens the incision and performs a distinct repair; the operative report should support each service.

Is modifier 50 appropriate for bilateral repair?

No. The abdominal wall repair is not reported with a bilateral adjustment under the CMS rule for this code.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

What should the operative note document?

Document the abdominal wound disruption, whether evisceration occurred, and the operative repair performed on the abdominal wall. This helps distinguish the service from superficial wound care or hernia repair.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
