DESCRIPTIONVertebral Axial Decompression (VAX-D) is a type of lumbar traction that has been investigated as a technique to reduce intravesical pressure and relieve low back pain associated with herniated lumbar discs or degenerative lumbar disc disease.
A pelvic harness is worn by the patient. The specially equipped table on which the patient lies is slowly extended, and a distraction force is applied via the pelvic harness until the desired tension is reached followed by a gradual decrease of the tension. The cyclic nature of the treatment allows that patient to withstand stronger distraction forces compared to static lumbar traction techniques. An individual session typically includes 15 cycles of tension and 10 to 15 daily treatments may be administered. Several devices used for vertebral axial decompression have received 510(k) marketing clearance from the US Food and Drug Administration (FDA). According to the FDA labeled indications, vertebral axial decompression may be used as a treatment modality for patients with incapacitating low back pain, and for decompression of the intervertebral discs and facet joints.
POLICYVertebral axial decompression (VAX-D) is considered investigational.
POLICY EXCEPTIONSFederal Employee Program (FEP) may dictate that all FDA-approved devices, drugs or biologics may not be considered investigational and thus these devices may be assessed only on the basis of their medical necessity.
Investigative service is defined as the use of any treatment procedure, facility, equipment, drug, device, or supply not yet recognized by certifying boards and/or approving or licensing agencies or published peer review criteria as standard, effective medical practice for the treatment of the condition being treated and as such therefore is not considered medically necessary.
The coverage guidelines outlined in the Medical Policy Manual should not be used in lieu of the Member's specific benefit plan language.
