What 43886 covers
This service addresses a problem with the subcutaneous access port used for an adjustable gastric band, such as a port that has shifted or cannot be accessed as intended. The surgeon exposes the port through an open incision and revises the port component; the work is limited to that component rather than revision of the band or gastric anatomy. It may be performed in a hospital or other surgical setting by a surgeon managing the patient’s bariatric procedure.
Report this code when the operative documentation supports an open approach and revision limited to the subcutaneous port. Distinguish it from removal alone, removal with replacement, and a broader revision of the gastric restrictive procedure. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

43886 billing questions
When should I report 43886 instead of 43887?
Use 43886 when the surgeon revises the port component. Code 43887 describes removal of the port component without replacement.
How does 43886 differ from 43888?
43886 is for revision of the existing port component. Report 43888 when the port is removed and replaced.
Can I report 43886 when the surgeon revises the band or stomach?
No. This code is limited to revision of the subcutaneous port component; documentation of work on the band or gastric anatomy calls for code selection based on that broader service.
What documentation supports 43886?
The operative report should establish the open approach, identify the port component, and describe the revision performed. It should make clear whether the port was removed or replaced, which may point to a different code.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and related postoperative care for 90 days are included in the global period. When other procedures are performed in the same session, Medicare applies its standard multiple-procedure reduction.
May an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
