Orthopedic surgery
About 27580: Knee joint fusion surgery
Reports surgical fusion of the knee to create a stable, immobile joint, typically as salvage for severe pain, infection, or failed reconstruction.
Code 27580 describes an operation that fuses the knee joint, eliminating motion to provide a stable limb. Orthopedic surgeons may use it as a salvage procedure for a severely damaged or unstable knee, including some cases of infection or failed knee replacement when another reconstruction is not suitable. The procedure is generally performed in a hospital or other surgical facility.
Report the code when the surgeon performs knee arthrodesis, not for fracture fixation, manipulation of a stiff knee, or prosthesis removal alone. The operative report should support the fusion, the treated side, and the clinical reason for choosing arthrodesis. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

27580 billing questions
When should I report 27580 instead of a knee replacement code?
Use 27580 when the surgeon fuses the knee rather than replacing or revising its joint surfaces. The operative report should document the arthrodesis and its salvage rationale.
Can prosthesis removal be reported with the fusion?
A surgeon may remove an infected or failed knee prosthesis as part of a salvage operation before fusion. Code 27488 describes knee prosthesis removal; document the work performed and consider applicable coding edits.
Does 27580 include routine postoperative visits?
Yes. Its 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
How does Medicare handle an assistant or co-surgeon?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, while team surgery is not permitted under the stated CMS rules.
How is bilateral knee fusion reported?
For bilateral procedures reported with modifier 50, CMS pays 150% under the stated rule. The documentation should establish that both knees were treated.
What happens when other 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, with payment at 50%.
