Orthopedic surgery
About 27340: Prepatellar bursa excision
Reports surgical removal of the prepatellar bursa, typically for persistent symptomatic bursitis involving the superficial tissue over the kneecap.
This procedure removes the prepatellar bursa, the fluid-filled sac in front of the kneecap. An orthopedic surgeon commonly performs it for persistent, symptomatic prepatellar bursitis, including a chronically thickened or repeatedly inflamed bursa. The operative report should identify the prepatellar location and describe removal of the bursa, rather than removal of a knee-joint structure or a separate soft-tissue mass.
Report the service when the documented work is excision of the prepatellar bursa. Medicare assigns a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, Medicare pays the highest-valued procedure in full and reduces other procedures to 50%. For bilateral surgery reported with modifier 50, payment is at 150%. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.

27340 billing questions
How is this different from removing a Baker cyst?
This code is for removal of the bursa over the kneecap. A popliteal, or Baker, cyst behind the knee is a different condition and is reported with 27345 when excised.
Can aspiration of the bursa be reported instead?
Aspiration or injection of a major joint or bursa is a different service from surgical excision. Code 20610 may apply to aspiration or injection when that service is performed and documented.
What documentation supports reporting this code?
Document the prepatellar location, the condition prompting surgery, and the operative work identifying and removing the bursa. The note should distinguish the bursa from a separate soft-tissue mass or an intra-articular structure.
How does Medicare handle bilateral excision?
When the procedure is performed bilaterally and reported with modifier 50, Medicare pays at 150%.
Are assistant or co-surgeon claims payable?
Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
