About 27552: Closed knee dislocation reduction under anesthesia
Report this service for closed reduction of a dislocated tibiofemoral knee when anesthesia is required, rather than reduction without anesthesia or open treatment.
This service covers closed reduction of a tibiofemoral knee dislocation when anesthesia is required. The clinician restores the joint alignment without surgically opening the knee; an orthopedic surgeon commonly performs the reduction in an operating room or another setting equipped to provide anesthesia. A traumatic knee dislocation is distinct from a dislocated patella, which involves the kneecap rather than the tibiofemoral joint.
Choose this code when the record supports a knee dislocation, a closed reduction, and the need for anesthesia. Document the injury, reduction performed, and anesthesia context; use the code for reduction without anesthesia when that is the service instead. This is a major procedure with a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure 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 requires documented medical necessity; co-surgeons and team surgery are not permitted.

27552 billing questions
How does this differ from 27550?
Use 27552 when closed reduction of the tibiofemoral knee dislocation requires anesthesia. Code 27550 is for closed treatment without anesthesia.
Can the reduction be coded with open treatment?
This code describes closed reduction. If the knee is surgically opened for treatment, consider the applicable open-treatment code, such as 27556 or 27557, based on the procedure performed.
Is a dislocated kneecap reported with this code?
No. This code concerns tibiofemoral knee dislocation; patellar dislocation treatment is represented by codes such as 27560 or 27562, depending on the circumstances.
What documentation supports reporting 27552?
Document the tibiofemoral knee dislocation, the closed reduction, and that anesthesia was required. The record should make clear that the service was not an open reduction.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
When is an assistant at surgery payable?
CMS payment for an assistant at surgery is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted for this code.
