These services may or may not be covered by all HealthPartners plans. Please see your plan documents for your own 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.
The provider and facility will be liable for payment unless:
- The provider notifies the member that a specific service has been determined by HealthPartners to be investigational/experimental; and
- The member signs a waiver agreeing to pay for the specific non-covered service being rendered; and
- The claim has been billed with a GA modifier indicating such. If the member has signed a waiver agreeing to pay for the specific service then the member will be liable for payment.
Please Note: This policy does not address standard electromyography (EMG). Standard EMGs are covered without prior authorization.
Nerve conduction studies using portable automated devices are considered investigational/experimental and are therefore not covered.
Nerve conduction studies are performed to evaluate and document a diagnosis of neuropathy and conditions involving sensory nerve dysfunction. Both automated and standard nerve conduction studies involve electrical stimulation of peripheral nerves and the resulting electrical responses.
Automated nerve conduction studies using portable devices can be performed in the primary care setting. The NC-stat system developed by NeuroMetrix, Inc., the Neural-Scan, and the Brevio NCS monitor are examples of this type of technology.
Standard nerve conduction studies (not addressed in this policy) are usually performed in conjunction with invasive needle electromyography (EMG) testing, and are done at a neurological testing facility.
If available, codes for a procedure, device or diagnosis are listed below for informational purposes only, and do not guarantee member coverage or provider reimbursement. The list may not be all inclusive.
Motor and/or sensory nerve conduction, using preconfigured electrode array(s), amplitude and latency/velocity study, each limb, includes F-wave study when performed, with interpretation and report
Noninvasive electrodiagnostic testing with automatic computerized hand-held device to stimulate and measure neuromuscular signals in diagnosing and evaluating systemic and entrapment neuropathies
