About 27558: Open knee dislocation repair with cruciate ligament repair
Reports open treatment of a tibiofemoral knee dislocation when the operation includes repair of one or more cruciate ligaments.
An orthopedic surgeon typically reports this service for operative treatment of a tibiofemoral knee dislocation when the procedure includes repair of a cruciate ligament. These injuries may involve substantial disruption of the knee’s stabilizing ligaments and are generally managed in an operating room. The operative work may include reducing the dislocated joint, stabilizing it, and repairing associated ligaments; the code also accommodates meniscal repair performed with the dislocation treatment.
Choose this code when the documented open treatment includes cruciate ligament repair, rather than open treatment without ligament repair or ligament repair that does not include a cruciate ligament. The operative report should establish the dislocation, the open approach, and the ligament structures repaired. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur 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%. Assistant-at-surgery payment may be made, and co-surgeons are permitted; team surgery is not permitted.

27558 billing questions
How does this differ from 27557?
Use 27558 when the open knee-dislocation treatment includes repair of a cruciate ligament. Code 27557 is for the corresponding ligament-repair treatment when cruciate repair is not included.
When would 27556 be a better fit?
Use 27556 for open treatment of a knee dislocation when the procedure does not include ligament repair. The operative note should support the services actually performed.
Is meniscal repair included in this code?
The code accommodates meniscal repair performed with the open knee-dislocation treatment and ligament repair. Do not treat that associated repair as a separate service solely because it is documented.
Does the code have a 90-day global period?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
How is bilateral treatment reported?
CMS identifies this as a bilateral procedure; reporting modifier 50 is paid at 150%. Document the treatment performed on each side.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made, and co-surgeons are permitted. CMS does not permit team-surgery billing for this code.
