Gynecologic procedure
About 56441: Lysis of labial adhesions
Reports procedural separation of fused labial tissue, commonly for symptomatic labial adhesions when a clinician performs lysis in an office or procedure setting.
This service involves separating adhesions that join the labia, typically the labia minora. It is often performed for a child with symptomatic fusion, such as urine trapping, spraying, or local discomfort. A pediatric or general gynecologist, or another qualified clinician, may perform the procedure in an office or procedure setting; the technique and need for anesthesia depend on the patient and extent of the adhesion.
Report 56441 when the clinician actually performs lysis, not merely evaluates the adhesions or recommends conservative treatment. The note should identify the adhesion, clinical indication, and procedure performed. CMS assigns a 10-day global period, so related postoperative visits during that period are included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

56441 billing questions
When should 56441 be selected instead of 56442?
Use 56441 for separating labial adhesions. Code 56442 describes a procedure involving the hymen, not fused labial tissue.
Does the 10-day global period include follow-up visits?
Related postoperative visits during the 10-day global period are included in 56441.
Can modifier 50 be used for adhesions on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code; do not append modifier 50.
How does a same-session procedure affect payment?
When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple-procedure reduction.
What documentation supports reporting 56441?
Document the labial adhesion, why procedural separation was indicated, and the lysis performed. An evaluation or treatment recommendation without lysis does not support this procedure code.
Can an assistant or another surgeon be reported?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted for this code.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
