December 2016 Texas Medicaid Provider Procedures Manual

Medical and Nursing Specialists, Physicians, and Physician Assistants Handbook : 9 Physician : 9.2 Services, Benefits, Limitations, and Prior Authorization : 9.2.43 Neurostimulators : Neuromuscular Electrical Stimulation (NMES)
NMES application and the rental or purchase of devices and conductive garments are a benefit of Texas Medicaid when medically necessary and prior authorized. Prior authorization requests for NMES must include documentation of a spinal cord injury or disuse atrophy that is refractory to conventional therapy.
NMES may be reimbursed using the following procedure codes:
The rental of a NMES device may be considered before purchase and is limited to a one-month trial period with consideration for one additional month’s trial with documentation of medical necessity. Supplies are considered to be part of the rental and will not be separately reimbursed. Garments may be considered for reimbursement during the rental period when medically necessary.
The purchase of a NMES device is limited to once per five years, and may be reimbursed when there is documentation of successful test stimulation (during rental or other therapeutic period) that showed improvement as measured by the following:
Garments may be considered for reimbursement during the purchase period when medically necessary.
NMES may be reimbursed when used to treat muscle disuse atrophy when brain, spinal cord, and peripheral nerve supply to the muscle is intact, as well as other non-neurological conditions. Examples of NMES treatment for non-neurological conditions include, but are not limited to, casting or splinting of a limb, contracture due to scarring of soft tissue as in burn lesions, and hip replacement surgery until orthotic training begins.
The type of NMES that is used to enhance the ability to walk of SCI clients is commonly referred to as functional electrical stimulation (FES). These devices are surface units that use electrical impulses to activate paralyzed or weak muscles in precise sequence.
The use of NMES/FES is limited to SCI clients who have completed a training program which consists of at least 32 physical therapy sessions with the device over a period of three months.
The trial period of physical therapy will enable the treating physician to properly evaluate the client’s ability to use NMES/FES devices frequently and for the long term.
Physical therapy necessary to perform this training must be directly performed by the physical therapist as part of a one-on-one training program. The goal of physical therapy must be to train SCI clients on the use of NMES/FES devices to achieve walking, not to reverse or retard muscle atrophy.
NMES/FES is a benefit for SCI clients who have all of the following characteristics:
Clients with muscle and joint stability for weight bearing at upper and lower extremities that can demonstrate balance and control to maintain an upright posture while standing independently for at least three minutes.
Clients who possess high motivation, commitment, and cognitive ability to use such devices for ambulation, as established by provider interview and documentation.
NMES and FES used for walking is not a benefit in SCI clients with any of the following:
