About 20690: Uniplanar external fixation application
Report 20690 when an orthopedic surgeon applies a unilateral external fixation frame with pins or wires arranged in a single plane to stabilize bone.
An orthopedic surgeon applies a unilateral external frame, anchoring it to bone with pins or wires arranged in one plane. The frame can stabilize a fracture or an osteotomy while the bone heals. This service is typically performed in an operating room or another surgical setting; the defining feature is the single-plane fixation configuration, not the number of pins or wires.
Choose this code when the operative record supports application of a single-plane frame, rather than a multiplanar construct. Document the treated side and bone, the indication, and the frame configuration. The 90-day global period includes the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

20690 billing questions
How does 20690 differ from 20692?
20690 is for a unilateral external frame with pins or wires in one plane. Use 20692 when the fixation is arranged in more than one plane.

No. Select the code based on the external fixation system's configuration, not the number of pins or wires. Document the frame arrangement in the operative report.
Can modifier 50 be used when both sides are treated?
No. CMS identifies bilateral adjustment as inappropriate for 20690. The descriptor and anatomy do not support modifier 50.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days. The application and this related care are part of the surgical episode.
Can an assistant or co-surgeon be paid for 20690?
Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.
How is 20690 paid when another procedure is performed in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50% when performed in the same session.
