What 27831 covers
This service treats a dislocation where the fibular head meets the tibia near the knee. The clinician manipulates the joint to restore alignment without surgically opening it. An orthopedic surgeon or other qualified clinician may provide the treatment in an emergency department, hospital, or office setting. The record should identify the proximal tibiofibular dislocation and describe the reduction performed, post-reduction findings, and treatment plan.
Choose this code when manipulation is performed; the closed-treatment code without manipulation is the nearby alternative when the joint is treated without that maneuver. The 90-day global period includes the day-before preoperative visit and related postoperative care during the following 90 days. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others at 50%. For bilateral treatment, modifier 50 is paid at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
