What 27840 covers
This code describes closed treatment of an ankle joint dislocation without anesthesia. The clinician restores alignment without surgically exposing the joint; the service may be provided by an emergency physician or an orthopedic surgeon in an emergency department, hospital, or office setting. The record should establish the dislocation, the closed method used, and that anesthesia was not used.
Choose this code rather than the anesthesia-requiring closed-treatment code when the documented circumstances meet that distinction; open treatment belongs to a different code. Medicare assigns a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral treatment, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
