What 22610 covers

A spine surgeon performs this fusion through a posterior approach, joining one thoracic spinal level to promote bone union and stability. It may be part of surgery for thoracic instability, deformity, or a fracture requiring stabilization. These procedures are typically performed in a hospital operating room; Medicare’s 2024 claims show facility services for this code and no office services.

Select the code when the operative report supports a posterior or posterolateral fusion at a single thoracic level. Document the spinal region, level fused, approach, and fusion work performed; use the applicable add-on code when additional levels are fused. Graft material and spinal instrumentation may be reported separately when the work and applicable coding requirements support them. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment and co-surgeons are permitted; team surgery is not.

22610 billing questions

How does this differ from 22600 or 22612?

The spinal region determines the primary code: 22610 is for a single thoracic level, 22600 for cervical, and 22612 for lumbar.

When is 22614 reported with this code?

Use 22614 for each qualifying additional spinal level fused beyond the primary level. The operative report should identify the additional level or levels.

Can instrumentation or bone graft be reported separately?

Separate reporting may be appropriate when instrumentation or graft work is performed and the requirements of the applicable code are met. The operative report should describe the work and materials used.

Does modifier 50 apply when both sides are fused?

No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 is not used to report the posterior fusion.

What postoperative care is included in the global period?

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

May an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be made, and co-surgeons are permitted. Team surgery is not permitted for this code.

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.
