Medical Necessity / Determination

Coverage Rationale / Medically Necessary Determination

Covered when ALL of the following are met:

ALL of the following

Motorized spinal traction devices (including vertebral axial decompression) are considered unproven and not medically necessary for treating neck and low back disorders due to insufficient evidence of efficacy.
Insufficient quality evidence exists to conclude that spinal unloading devices improve health outcomes for low back pain (LBP) or neck pain; available studies have methodological limitations and inconsistent results.

Not Covered — Rationale and Evidence Summary

Motorized spinal traction, including vertebral axial decompression, is considered unproven and not medically necessary for treating neck and low back disorders due to insufficient evidence of efficacy.

The policy states there is insufficient quality evidence (methodological limitations, small samples, short follow-up, inconsistent results) to conclude that spinal unloading devices improve health outcomes for low back pain or neck pain.

Citation	Evidence
Wegner et al. (Cochrane review 2013)	32 RCTs; low- to moderate-quality evidence that traction may make little or no difference in pain, function, or global improvement
Vanti et al. (2023)	Systematic review/meta-analysis: very low to low-quality evidence; no difference between traction modalities short-term
Colombo et al. (2020)	Systematic review: low-quality evidence of statistically significant but not clinically meaningful pain reduction for cervical radiculopathy
Multiple RCTs/case series (2006-2023)	Mixed results, methodological limitations, small samples, short follow-up; insufficient evidence of long-term benefit

S9090

Background, Definitions, and Evidence

Vertebral axial decompression is a form of spinal traction that uses a computer-driven table and a pelvic harness to apply cyclical distraction forces to the spine; the table is slowly extended to reach a desired tension which is then gradually decreased, and the number of sessions varies.

The policy summarizes multiple randomized controlled trials, systematic reviews, and case series which overall provide low- to very-low quality or inconsistent evidence regarding efficacy for low back pain, lumbar radiculopathy, or neck pain.

Vertebral axial decompression: A motorized spinal traction technique involving a computer-driven table and pelvic harness to apply cyclical distraction forces to the spine.

Motorized spinal traction / nonsurgical spinal decompression (NSD): Mechanical traction modalities (including DRX9000, VAX-D, IDD, lordotic curve-controlled traction) intended to decompress intervertebral discs and reduce back/leg pain.
