Aetna is particularly picky when it comes to these procedures. See Aetna Medical Policy bulletin below:
VII.Non-pulsed radiofrequency facet denervation (also known as facet neurotomy, facet rhizotomy, or articular rhizolysis) is considered medically necessary for treatment of members with intractable cervical or back pain with or without sciatica in the outpatient setting when all of the following are met:
A.Member has experienced severe pain limiting activities of daily living for at least 6 months; and
B.Member has had no prior spinal fusion surgery; and
C.Neuroradiologic studies are negative or fail to confirm disc herniation; and
D.Member has no significant narrowing of the vertebral canal or spinal instability requiring surgery; and
E.Member has tried and failed conservative treatments such as bed rest, back supports, physiotherapy, correction of postural abnormality, as well as pharmacotherapies (e.g., anti-inflammatory agents, analgesics and muscle relaxants); and
F.Trial of facet joint injections has been successful in relieving the pain.
Non-pulsed radiofrequency facet denervation is considered experimental and investigational for all other indications because its effectiveness for indications other than the ones listed above has not been established.
Only 1 treatment procedure per level per side is considered medically necessary in a 6-month period.
