DESCRIPTION
Peripheral subcutaneous field stimulation (PSFS) is a form of neuromodulation intended to treat chronic neuropathic pain. Applications of PSFS being evaluated are craniofacial stimulation for headache and migraine, craniofacial pain, or occipital neuralgia. PSFS is also being investigated for low back, neck, and shoulder pain, inguinal and pelvic pain, thoracic pain, abdominal pain, fibromyalgia and postherpetic neuralgia. With this method, leads are placed subcutaneously within the area of maximal pain with the objective of stimulating the region of affected nerves, cutaneous afferents or the dermatomal distribution of the nerves, which then converge back on the spinal cord. The mechanism of action in PSFS is unknown. There are no FDA devices approved for this use. PSFS is an off-label use of spinal cord stimulation devices that have been FDA approved.
POLICY
Peripheral subcutaneous field stimulation is considered investigational.
IMPORTANT REMINDERS
Any specific products referenced in this policy are just examples and are intended for illustrative purposes only. It is not intended to be a recommendation of one product over another, and is not intended to represent a complete listing of all products available. These examples are contained in the parenthetical e.g. statement.
We develop Medical Policies to provide guidance to Members and Providers. This Medical Policy relates only to the services or supplies described in it. The existence of a Medical Policy is not an authorization, certification, explanation of benefits or a contract for the service (or supply) that is referenced in the Medical Policy. For a determination of the benefits that a Member is entitled to receive under his or her health plan, the Member's health plan must be reviewed. If there is a conflict between the medical policy and a health plan or government program (e.g., TennCare), the express terms of the health plan or government program will govern.
ADDITIONAL INFORMATION
Prospective controlled trials comparing peripheral subcutaneous field stimulation with placebo or alternative treatment modalities are needed to determine the efficacy of this treatment for chronic pain. Currently the evidence is insufficient to determine the effects of the technology on health outcomes.
