What 20662 covers

A spine or orthopedic surgeon applies a halo frame anchored at the pelvis to provide traction or stabilization. A typical clinical use is gradual traction for a severe spinal deformity, such as complex scoliosis, before corrective surgery. The service is generally performed in a hospital or surgical setting, with the fixation placed and adjusted to the patient’s treatment plan.

Select this code for application at the pelvis, rather than a cranial or femoral halo. The operative report should identify the clinical indication, pelvic fixation site, apparatus applied, and relevant procedural details. Medicare assigns a 90-day global period, which 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 for this code. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

20662 billing questions

How is this code distinguished from cranial halo application?

Use this code when the halo apparatus is applied at the pelvis. Cranial halo application is reported with the code for cranial placement.

When would a femoral halo code be used instead?

The femoral halo code applies when the apparatus is placed at the femur, rather than at the pelvis.

What documentation supports pelvic halo application?

Document the indication, the pelvic fixation site, the apparatus applied, and the operative work performed. For assistant-at-surgery payment, the record must also support medical necessity.

Can modifier 50 be reported?

No. CMS identifies bilateral adjustment as inappropriate for this code because of its descriptor or anatomy.

How does the 90-day global period affect postoperative billing?

The day-before preoperative visit and 90 days of related postoperative care are included in the global period.

How are other procedures in the same session paid?

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

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.
