What 56420 covers
CPT 56420 describes opening and draining an abscess involving a Bartholin gland, commonly presenting as a tender, one-sided swelling near the vaginal opening. A gynecologist or another physician may perform the procedure in an office, clinic, or facility setting. The service addresses an abscess; a noninfected Bartholin cyst or an abscess elsewhere on the vulva calls for a different procedural choice.
Report the code when the documented procedure drains a Bartholin gland abscess. The note should identify the gland or site and describe the abscess and drainage performed. The procedure has a 10-day global period, so related postoperative visits during that period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.

56420 billing questions
How do I distinguish 56420 from 56405?
Use 56420 for an abscess of the Bartholin gland. Code 56405 is for incision and drainage of a vulvar or perineal abscess not identified as a Bartholin gland abscess.
How does 56420 differ from 56440?
56420 is for draining a Bartholin gland abscess. 56440 describes marsupialization of a Bartholin gland cyst, a different procedure.
Should modifier 50 be appended for bilateral disease?
No. CMS identifies bilateral adjustment as inappropriate for this code; do not use modifier 50.
Are related postoperative visits separately reported during the global period?
Related postoperative visits during the 10-day global period are included in the procedure payment.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple procedure reduction. An assistant at surgery is not paid; co-surgeons and team surgery are not permitted.
