Billing tips

Always bill 22552 in conjunction with primary code 22551 (first level cervical arthroplasty). Code 22552 cannot be billed alone and will automatically deny without the primary procedure code on the same claim.
Impact: Prevents 100% denial of $385.25 claim; ensures proper code sequencing for multi-level procedures
Report 22552 once for each additional intervertebral level beyond the first. For a three-level cervical arthroplasty, bill 22551 x1 and 22552 x2, ensuring correct unit count matches operative report.
Impact: Each additional unit represents $385.25 in reimbursement; incorrect unit count can result in underpayment of hundreds of dollars per case
Document specific vertebral levels treated (e.g., C4-C5, C5-C6, C6-C7) in operative report and ensure these match claim submission. MAC auditors frequently review multi-level spine procedures for medical necessity at each level.
Impact: Reduces audit risk and supports medical necessity; prevents recoupment of $385.25+ per level during post-payment audits
Do not append modifier 51 to 22552 as it is designated as an add-on code (+) and is exempt from multiple procedure payment reductions per CMS guidelines.
Impact: Prevents improper payment reduction; preserves full $385.25 reimbursement per additional level
Verify pre-authorization requirements for multi-level cervical arthroplasty with both Medicare and commercial payers. Many require prior authorization for 2+ level procedures and specific medical necessity criteria.
Impact: Prevents denial of entire claim which may exceed $1,500-2,000 for multi-level procedures; saves appeal costs and time
Bill facility and professional components separately. In facility settings, both rates are $385.25 per level, but proper place of service codes (21, 22, or 24) are critical for correct adjudication.

Frequently asked questions

What is the Medicare reimbursement rate for CPT code 22552 in 2025?

The 2025 Medicare national average reimbursement rate for CPT code 22552 is $385.25 for both facility and non-facility settings. This rate is based on 11.91 total RVUs (6.5 work RVU, 3.29 practice expense RVU, and 2.12 malpractice RVU) multiplied by the 2025 conversion factor of 32.3465.

Can CPT 22552 be billed alone without another procedure code?

No, CPT 22552 is an add-on code (indicated by the + symbol in CPT manual) and cannot be billed independently. It must be reported in conjunction with the primary cervical disc arthroplasty code 22551. Billing 22552 without 22551 will result in automatic denial.

How many times can I bill CPT 22552 for a multi-level cervical arthroplasty?

You can bill CPT 22552 once for each additional intervertebral level beyond the first level. For example, a three-level cervical arthroplasty would be coded as 22551 x1 (first level) and 22552 x2 (two additional levels). There is no specific CMS limit, but medical necessity must be documented for each level, and most payers scrutinize cases beyond 2-3 total levels.

What modifiers should be used with CPT code 22552?

CPT 22552 typically does not require modifier 51 as it is an add-on code exempt from multiple procedure reductions. Modifier 59 may be appropriate when distinguishing separate anatomical levels from bundled services. Modifier 22 can be used for increased complexity with supporting documentation. Modifiers 76 or 78 apply for repeat procedures in specific circumstances. Always verify payer-specific modifier requirements.

What is the difference between CPT 22552 and 22551?

CPT 22551 is the primary code for cervical artificial disc arthroplasty at the first intervertebral level, while 22552 is the add-on code for each additional level treated during the same operative session. Code 22551 has higher reimbursement reflecting the base procedure work, while 22552 captures the incremental work of treating additional levels. Both codes require anterior approach to the cervical spine.

Does CPT 22552 require prior authorization from Medicare or commercial insurance?

Medicare does not universally require prior authorization for 22552, but many Medicare Advantage plans and commercial payers do require pre-authorization for multi-level cervical arthroplasty procedures. Requirements vary by payer and patient's specific plan. Always verify authorization requirements before scheduling surgery to prevent claim denials. Some payers have specific medical necessity criteria limiting the number of levels approved.

What documentation is needed to support billing CPT 22552?

Required documentation includes an operative report detailing each specific vertebral level treated, the approach used, discectomy performed, endplate preparation, and artificial disc insertion at each additional level. Pre-operative imaging (MRI/CT) must demonstrate pathology at each level. Documentation should include prosthesis type and size for each level, fluoroscopic confirmation of placement, and medical necessity justification for multi-level treatment. Failed conservative treatment records strengthen medical necessity support.
