What 20665 covers

This service removes cranial traction tongs or a halo apparatus used to stabilize the head and cervical spine. It is typically performed by an orthopedic spine surgeon or neurosurgeon when the period of skeletal traction or halo immobilization is complete. Removal may take place in a facility or another setting equipped to manage the patient and device.

Report the removal service when tongs or a cranial halo are taken off separately, rather than as part of an application service that includes removal. The record should identify the device removed and document the removal performed. The code has a 10-day global period, so related postoperative visits during that period are included. 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% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; 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.

20665 billing questions

When should 20665 be reported instead of a halo application code?

Use 20665 when cranial tongs or a halo are removed as a separate service. Application codes that include removal describe a different service when the device is applied.

Does 20665 include related follow-up visits?

Yes. The 10-day global period includes related postoperative visits during those 10 days.

Can modifier 50 be reported for removal on both sides?

No. Modifier 50 is inappropriate for this code.

How is 20665 affected when other procedures are performed in the same session?

The highest-valued procedure is paid in full, and other procedures are subject to the standard 50% multiple-procedure reduction.

Can an assistant surgeon or co-surgeon be reported?

Assistant-at-surgery payment is available only when medical necessity is documented. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
