What 27842 covers

An orthopedic surgeon or other qualified physician uses closed manipulation to restore alignment of a dislocated ankle without opening the joint. The service is typically performed in a hospital or ambulatory surgical setting when the reduction requires anesthesia. Documentation should identify the ankle dislocation, the closed reduction performed, and the anesthesia requirement; post-reduction findings help show the result of treatment.

Select 27842 when the dislocation is treated closed and anesthesia is required. Use 27840 when closed treatment is performed without anesthesia; open treatment belongs to a different code. The code has a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures are reduced to 50%. For bilateral treatment, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this code, and co-surgeon and team-surgery billing are not permitted.
