NMES for disuse atrophy

Covered when ALL of the following are met:

NMES for disuse atrophy: NMES is medically necessary when used as one component of a comprehensive rehabilitation program for treatment of disuse atrophy when the nerve supply to the atrophied muscle is intact and any of the following atrophy indications are present

Atrophy indications: A. Contractures due to scarring of soft tissue (e.g., burn lesions); B. Previous casting or splinting of a limb; C. Major knee surgery with failure to respond to physical therapy; D. Recent hip replacement and NMES will be used until physical therapy begins

FES for spinal cord injury

Covered when ALL of the following are met:

FES for SCI general criteria: Member has brisk muscle contraction to stimulation and sensory perception of electrical stimulation sufficient for muscle contraction; at least six months have passed since recovery from spinal cord injury and restorative surgery; member is highly motivated, committed, and has the cognitive ability to use FES devices for walking; successful completion of a training program consisting of at least 32 physical therapy sessions with the device over a three-month period; member demonstrates willingness for long-term use; none of the contraindications in II.F are present

Contraindications (II.F) include: cardiac pacemaker; severe scoliosis or severe osteoporosis; skin disease or cancer at area of stimulation; irreversible contracture; autonomic dysreflexia

FES lower extremity-specific: If lower extremity FES is requested, all of the following must be met: intact lower motor units (L1 and below, including both muscle and peripheral nerve); muscle and joint stability adequate for weight bearing and ability to demonstrate balance and control to maintain an upright support posture independently; transfers independently and demonstrates independent standing tolerance for at least three minutes; demonstrates hand and finger function to manipulate controls; no hip and knee degenerative disease and no history of long bone fracture secondary to osteoporosis

Peroneal nerve stimulators

Covered when the indication is incomplete spinal cord injury:

Peroneal nerve stimulator coverage: Peroneal nerve stimulators (e.g., NESS L300, NESS L300 Plus, L300 Go System, WalkAide, Odstock ODFS Dropped Foot Stimulator) are medically necessary for incomplete spinal cord injury

Unproven indications / Not covered

Unproven indications: Peroneal nerve stimulators have not been proven safe and effective for any indication other than incomplete spinal cord injury (including but not limited to foot drop in cerebral palsy, multiple sclerosis, traumatic brain injury, or stroke). Neuromuscular electrical stimulation for other indications (e.g., idiopathic scoliosis, heart failure) is not proven safe and effective.

Requests for devices for non-supported indications may be denied

Peroneal nerve stimulators (examples: NESS L300, NESS L300 Plus, L300 Go System, WalkAide, Odstock ODFS Dropped Foot Stimulator) have a limited evidence base in this policy. They are considered medically necessary only for the indication of incomplete spinal cord injury. The policy explicitly states that these devices have not been proven safe and effective for any indication other than incomplete spinal cord injury, and lists examples of noncovered uses such as foot drop due to cerebral palsy, multiple sclerosis, traumatic brain injury, or stroke.

The policy clarifies that neuromuscular electrical stimulation (NMES) is not proven safe and effective for indications beyond those specified as medically necessary. The document explicitly names examples of other indications for which NMES/FES lacks supporting evidence, including idiopathic scoliosis and heart failure, and therefore considers use for those conditions not supported by the policy.

Consistent with the policy’s coverage stance, requests for NMES treatment for diagnoses not listed as medically necessary are considered not proven safe and effective. The policy gives an explicit example: NMES for idiopathic scoliosis (and similarly for conditions such as heart failure) is categorized as not medically necessary because the evidence does not support safety and effectiveness for those uses.

Provider Actions and Authorization Requirements

Prior Authorization

Prior Authorization Required

Prior authorization is required for neuromuscular electrical stimulation (NMES), functional electrical stimulation (FES), and peroneal nerve stimulator requests to demonstrate medical necessity prior to coverage determination.

Affects HCPCS E0745, E0764, E0770 (informational)

Note

Conservative Therapy Prerequisite for NMES

NMES is covered only as one component of a comprehensive rehabilitation program for treatment of disuse atrophy when the nerve supply to the atrophied muscle is intact. NMES is typically considered after failure of or as an adjunct to conservative therapy such as physical therapy, splinting/casting management, and other noninvasive measures.

Indications include contractures from soft-tissue scarring (e.g., burns), prior casting or splinting, major knee surgery unresponsive to PT, or recent hip replacement until PT begins.

Documentation Required

Required Clinical Documentation for FES

For FES requests the following clinical documentation must be provided to support medical necessity: evidence of brisk muscle contraction to stimulation and sensory perception sufficient for contraction; documentation that at least six months have passed since recovery from spinal cord injury and any restorative surgery; evidence of patient motivation, cognitive ability, and willingness for long‑term device use; proof of successful completion of a training program (minimum 32 physical therapy sessions over a three‑month period); and absence of contraindications (e.g., cardiac pacemaker, severe scoliosis/osteoporosis, skin disease/cancer at stimulation site, irreversible contracture, autonomic dysreflexia). If lower extremity FES is requested, document intact lower motor units (L1 and below), adequate muscle/joint stability for weight bearing, and independent transfers/standing tolerance of at least three minutes, plus hand/finger function to manipulate controls and no hip/knee degenerative disease or history of osteoporotic long‑bone fracture.

Include objective examination findings, therapy notes documenting the 32-session training, and any relevant imaging or surgical recovery dates.
List any contraindications evaluated and ruled out.

Denial Risk

Non‑Supported Indications for Peroneal Nerve Stimulators

Peroneal nerve stimulators (e.g., NESS L300, WalkAide, L300 Go, Odstock) are supported only for incomplete spinal cord injury. Requests for these devices for other diagnoses (for example, foot drop from cerebral palsy, multiple sclerosis, traumatic brain injury, or stroke) are not supported and lack proven safety/effectiveness.

Peroneal nerve stimulator requests for indications other than incomplete SCI will be denied as not proven safe and effective.

Definitions

Functional electrical stimulation (FES)

DefinitionFunctional electrical stimulation (FES): application of electrical stimulation to activate muscles to produce functional movement patterns (e.g., standing, walking) in patients with paraplegia; generally used for upper motor neuron lesions and not suitable for lower motor neuron lesions.

PurposeUsed to enhance functional activity of neurologically impaired patients by activating muscle groups to produce movement (standing, walking) and to therapeutically cycle limbs for strengthening.

Clinical effectsHas been shown to strengthen muscles, improve circulation, heal tissue, slow muscle atrophy, and reduce pain and spasticity.

Typical use settingProvided by skilled therapists as part of rehabilitation programs for patients with upper motor neuron lesions (e.g., paraplegia).

Threshold NMES (TES)

DefinitionThreshold NMES (also called threshold electrical stimulation, TES): very low intensity neuromuscular electrical stimulation that produces barely perceptible muscle contractions.

IntensityPerformed at very low intensity compared with low/medium/high NMES; elicits minimal, barely perceptible contraction.

Clinical roleUsed when minimal stimulation is desired while encouraging voluntary exercise of affected muscles to maintain or improve strength and function.
