Artificial intervertebral disc replacement-cervical
These services may or may not be covered by your HealthPartners plan. Please see your plan documents for your specific coverage information. If there is a difference between this general information and your plan documents, your plan documents will be used to determine your coverage.
Prior authorization is required for artificial cervical intervertebral disc replacement.
Artificial cervical intervertebral disc replacement is generally covered subject to the indications listed below and per your plan documents. This policy does not apply to artificial lumbar intervertebral disc replacement. Please see the lumbar-specific policy for details and applicable coverage criteria.
Indications that are covered
Artificial cervical intervertebral disc may be eligible for coverage when ALL of the following criteria are met:
- Clinical documentation indicates intractable radiculopathy and/or myelopathy with at least one of the following conditions producing symptomatic nerve root and/or spinal cord compression:
- Herniated disc; AND/OR
- Osteophyte formation
- Reports of radiographic studies such as CT, MRI or x-rays are submitted which confirm the conditions listed above.
- Patient must be skeletally mature.
- Patient must have tried and failed at least 6 weeks of conservative management (including rest, application of heat /ice, physical therapy, exercise, pain and/or anti-inflammatory medications).
NOTE: Conservative therapy must include physical therapy (PT) and may include activity modification, weight loss, and drug therapy. Documentation must correspond to the current episode of pain (within 6 months).
Formal physical therapy, at least four visits over a six week course, including active muscle conditioning is required, or there must be an explicit statement in the clinical documents that explains why such physical therapy is contraindicated. The requirement for physical therapy will not be met if there is a failure to complete prescribed physical therapy for non-clinical reasons. Documentation of formal physical therapy would be the therapist’s notes. If a patient is unable to complete physical therapy (PT) due to progressively, worsening pain and disability, the case will be reviewed on an individual basis by an internal physician reviewer. Documentation in the physical therapist’s notes demonstrating this must be submitted.
- Clinical documentation indicates a history of neck and/or arm pain as well as functional and/or neurological deficits.
- Cervical area being replaced and reconstructed is within discs C3-C7, and involves either a single-level or a contiguous 2-level discectomy for intractable radiculopathy and/or myelopathy
- The proposed device is FDA approved for both the condition being treated and for the number of levels being treated.
NOTE: Examples of FDA-approved artificial cervical spinal discs include: The Prestige® Cervical Disc System, the Bryan® Cervical Disc System, the ProDisc®-C, the MOBI-C Cervical Disc Prosthesis, the Secure-C Artificial Disc System, and the PCM Cervical Disc System. The MOBI-C and the Prestige LP Cervical Disc are the only artificial discs FDA-approved for use at both one and two contiguous levels.
Indications that are not covered
- Active systemic infection or infection at the surgical site
- Allergy to any of the device materials
- Osteopenia or osteoporosis
- Marked cervical instability on radiographs, defined as vertebral misalignment (subluxation) >3.5mm or angulation of the disc space >11 degrees greater than adjacent segments.
- Moderate to advanced degeneration of the intervertebral discs, characterized by bridging osteophytes, marked reduction or absence of motion, or collapse of the intervertebral disc space of > 50% of its normal height.
- Presence of significant facet arthritis at the level to be treated
- Significant cervical anatomical deformity or clinically compromised vertebral bodies at the level to be treated due to systemic disease, previous surgery, or trauma.
- Significant kyphotic deformity, significant reversal of lordosis, or significant spondylolisthesis
- Disc replacement(s) for symptoms necessitating concurrent additional surgical treatment (i.e. fusion)
- Disc replacement(s) for cervical level adjacent to a previous cervical fusion
Arthroplasty is the surgical repair of a joint.
Artificial cervical intervertebral disc replacement, also known as cervical disc arthroplasty, is a procedure which replaces a degenerated cervical (neck) disc with an artificial disc. The artificial disc is intended to relieve pain, preserve alignment, maintain spinal stability and flexibility, and prevent degeneration of adjacent discs. This type of surgery is an alternative to anterior cervical discectomy and fusion surgery.
Axial neck pain is musculoskeletal, characterized as neck or soft tissue pain which occurs solely along the spinal column.
Degenerative Disc Disease (DDD) is a general term used to describe the progressive drying out and deterioration of the intervertebral discs of the spine which lead to loss of flexibility and function. DDD develops over time as part of the normal aging process. It may cause neck stiffness and pain.
Herniated disc is a condition in which the outer portion (annulus fibrosus) of the vertebral disc is torn, enabling the inner portion (nucleus) to herniate or extrude through the fibers.
Kyphosis is an excessive outward curvature of the spine, which causes hunching of the back.
Lordosis is an excessive inward curvature of the spine.
Myelopathy is any functional disturbance or disease of the spinal cord.
Osteopenia refers to bone density that is lower than normal peak density but not low enough to be classified as osteoporosis.
Osteoporosis refers to a bone disease in which there is a thinning of the bones with reduction in bone mass due to depletion of calcium and bone protein. It predisposes a person to bone fractures. Osteoporosis is defined as a DEXA bone mineral density T-score equal to or worse than 2.5.
Osteophytes, or bone spurs, are bony outgrowths that form on the spine over a period of time. They are physical indications of degeneration in the spine.
Radiculopathy or radicular neck pain is caused by a compressed nerve in the spine. It can cause pain, numbness, tingling, or weakness along the course of the compressed nerve.
Spondylolisthesis is a condition in which one vertebrae slides over the one below it. It may lead to the spinal cord or nerve roots being squeezed.
If available, codes are listed below for informational purposes only, and do not guarantee member coverage or provider reimbursement. The list may not be all-inclusive.
