What 24640 covers
This service covers a clinician's manipulation to reduce radial head subluxation in a young child, commonly after an adult pulls or lifts the child by the hand or forearm. A pediatrician, emergency physician, or orthopedist may perform the reduction in an office or emergency department. Typical maneuvers involve rotating the forearm and flexing the elbow; the clinician assesses the child afterward for restored use of the arm.
Select this code when the documented condition is radial head subluxation and the clinician performs the reduction, rather than treating an elbow dislocation or fracture. Document the history and examination supporting the diagnosis, the manipulation performed, and the child's response. Related postoperative visits are included for 10 days. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures 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.

24640 billing questions
How is this different from an elbow dislocation code?
Use 24640 for radial head subluxation, commonly called nursemaid's elbow. Codes 24600 and 24605 describe closed treatment of an elbow dislocation, a different diagnosis.
Can this code be used for a radial head fracture?
No. For a radial head or neck fracture, select the fracture-treatment code that matches the treatment performed, such as 24650 or 24655.
Does the code include the reduction maneuver?
Yes. The manipulation to reduce the subluxation is the service represented by 24640; do not report a separate reduction code for that same maneuver.
What documentation supports reporting 24640?
Document findings consistent with radial head subluxation, the manipulation performed, and the child's response, such as return of comfortable arm use.
How does the 10-day global period affect follow-up?
Related postoperative visits during the 10-day global period are included in the procedure payment.
How is bilateral treatment reported?
For treatment of both elbows, modifier 50 is paid at 150%.
