Reimbursement
Important — educational use only. Code selection is the provider’s responsibility.
This information is provided for educational and informational purposes only and should not be construed as authoritative coding, billing, or legal advice. Amplio Spine does not recommend codes for specific cases and assumes no responsibility for coding. The choice of codes must be made by the surgeon based on the services actually performed and documented in the medical record. The entity billing Medicare and/or third-party payers is solely responsible for the accuracy of the codes assigned. While a code may exist describing certain procedures or technologies, it does not guarantee coverage, reimbursement, or payment. Amplio Spine does not promote the off-label use of its products.
Procedure Context
KeyLift is FDA-cleared as an interlaminar fusion system indicated to achieve supplemental fusion inthe non-cervical spine for treatment of lumbar spinal stenosis with or without Grade I stable spondylolisthesis. It is not intended for stand-alone use. Coding for a given case depends entirely on the procedures the surgeon performs and documents — for example, whether posterior or posterolateral lumbar arthrodesis is performed, whether decompression is performed, whether bone graft or biologic is placed, and whether instrumentation is documented.
Code Reference — codes that may be relevant when KeyLift is used
The codes below are presented as an educational reference. They may or may not describe the actual procedure performed in any given case. Code selection must be based on the operative record.
| CPT/HCPCS | Type | Descriptor | When it may be relevant |
|---|---|---|---|
| 22612 | CPT—Category I | Arthrodesis, posterior or posterolateral technique, single interspace; lumbar (with lateral transverse technique, when performed) | May be reported when the operative record documents posterior or posterolateral lumbar arthrodesis at a single interspace |
| 22614 | CPT—Category I (Add-on) | Arthrodesis, posterior or posterolateral technique, each additional vertebral segment (list separately) | May be reported as an add-on when arthrodesis is performed at additional segments |
| 22842 | CPT—Category I | Posterior segmental instrumentation; 3 to 6 vertebral segments | May be reported when the operative record documents posterior non-pedicle supplemental fixation, where supported by documentation |
| 22853/22859 | CPT—Category I | Insertion of interbody biomechanical device(s) / Insertion of intervertebral biomechanical device(s) | May be relevant where supported by the operative documentation |
| 22867 | CPT—Category I | Insertion of interlaminar/interspinous process stabilization/distraction device with open decompression, lumbar; single level | May be relevant when the operative documentation describes interlaminar stabilization without arthrodesis |
| 22868 | CPT—Category I (Add-on) | Each additional interspace, when performed (list separately) | May be reported as an add-on when reporting under the 22867 pathway |
The code options above may or may not represent the actual procedure performed in any given case and are presented as a reference only. The choice of codes must be made by the surgeon as documented in the medical record. When making coding decisions, providers are encouraged to seek input from the AMA, relevant medical societies, CMS, their local Medicare Administrative Contractor, and other health plans to which they submit claims.
*Note on KeyLift FDA-cleared Indications for Use
Amplio Spine’s published surgical technique for KeyLift expressly describes graft placement into the implant cavity and around the spinous processes, and decortication of the articular surfaces when fusing through the facets. The FDA-cleared Indications for Use state that KeyLift is intended for “achieving supplemental fusion” and is not intended for stand-alone use.
Taken together, these published sources are inconsistent with any blanket characterization of KeyLift as involving “no decortication, grafting, or fusion technique.” Whether the procedure performed in any given case involves arthrodesis is a determination for the surgeon based on the work actually performed and documented in the operative record. Bottom line, Amplio Spine does not direct or recommend any specific code for KeyLift. KeyLift is not coded based on the device itself — it is coded based on the procedures the surgeon performs and documents in the operative record. Established spinal coding constructs exist; whether any of them applies in a particular case is a determination for the coder and spine specialist.
Educational reimbursement support — how Amplio Spine can help
Amplio Spine’s team can provide educational information about the FDA-cleared Indications for Use, product specifications, and publicly available payer policy and code descriptors that may be relevant to KeyLift cases. We do not recommend codes for specific cases and we do not promote off-label use. All coding and billing decisions are the responsibility of the provider. To request educational materials, email hello@ampliospine.com with the subject line Educational Materials Request.
