Guidance for Connecticut Medicaid (HUSKY Health) providers on medical necessity, prior authorization requirements, and coverage determinations for NMES devices (HCPCS E0745 and E0744). Applies to CMAP-enrolled providers requesting NMES for HUSKY enrollees.
Removed definition of FES and the link to the FES policy; added a numeric clarification in the Procedure section and updated references.
Coverage Criteria for NMES Devices
Medically Necessary Indications (E0745)
Covered when ALL of the following are met
Examples listed are non-exclusive; clinical assessment required.
NMES DME medical necessity
NMES for disuse atrophy is medically necessary when:
Clinical documentation must support each element.
Not Medically Necessary: Scoliosis (E0744)
Not covered for idiopathic scoliosis per this policy.
Contraindications to NMES include presence of a cardiac pacemaker or implanted defibrillator and any implanted metallic or electric device in the area of stimulation. NMES should not be used in individuals with suspected or diagnosed epilepsy, in those with confirmed pregnancy, or in persons with any suspected serious heart conditions, disease, or disorders. Additionally, NMES is contraindicated when there is skin disease or cancers at the area of stimulation per manufacturer guidance and this policy.
NMES is considered investigational and not medically necessary for all indications beyond the specific disuse atrophy criteria described elsewhere in this policy due to insufficient evidence of safety and clinical efficacy in peer-reviewed literature. Requests for uses outside the covered disuse atrophy indication will be evaluated as investigational and may be denied.
Specifically, use of NMES for treatment of scoliosis (HCPCS E0744) is not medically necessary and is not covered under this policy for idiopathic scoliosis because there is insufficient evidence supporting safety and clinical effectiveness.
HCPCS Codes and Coverage Status
Provider Actions and Prior Authorization
Prior authorization required for NMES (effective Aug 1, 2025)
Prior authorization is required for NMES devices (HCPCS E0745 and E0744). Requests will be reviewed under DME review procedures and, if approved, authorized per the DME Rent to Purchase Policy. This prior authorization requirement is effective for requests on or after August 1, 2025 for HUSKY A, B, C, and D programs.
Provider action: submit DME prior authorization and follow rent-to-purchase rules
Submit requests through the DME prior authorization process and follow DME Rent to Purchase procedures if approved. Ensure the request includes the required documentation (see Required documentation block) and that the treating clinician is enrolled in CMAP.
Required documentation for authorization
Provide a fully completed authorization request via the web portal; include a signed prescription written within the past three (3) months from the treating physician, PA, or APRN enrolled in CMAP; and attach documentation from the ordering provider, written within the past three (3) months, supporting medical necessity per the Clinical Guidelines.
- Fully completed authorization request submitted via web portal
- Signed prescription dated within past 3 months from treating physician, PA, or APRN enrolled in CMAP
- Ordering provider documentation dated within past 3 months that supports medical necessity per Clinical Guidelines
Denial risk: investigational indications (including scoliosis)
Requests for indications other than disuse atrophy, and use of NMES for treatment of scoliosis (HCPCS E0744), are considered investigational and not medically necessary and may be denied.
- NMES for scoliosis (E0744) is investigational and not covered
- NMES for indications beyond the disuse atrophy criteria may be considered investigational and denied
Rental and Purchase Rules for NMES Devices
| Rule | Detail |
|---|---|
| Rent-to-purchase policy | If approved, an NMES device will be authorized as outlined in the DME Rent to Purchase Policy. |
| Review procedure | Requests for coverage of an NMES device will be reviewed in accordance with procedures in place for reviewing requests for durable medical equipment; coverage determinations are based on submitted case‑specific information. |
Required Documentation for Authorization
Required: web portal submission, recent signed prescription, and supporting documentation
Authorization requests must be submitted via the web portal and include a signed prescription dated within the past three (3) months from a CMAP‑enrolled treating clinician plus supporting provider documentation within the past three (3) months demonstrating medical necessity.
- Authorization request submitted through web portal
- Signed prescription from treating physician/PA/APRN (within 3 months) from CMAP‑enrolled clinician
- Ordering provider documentation (within 3 months) supporting medical necessity
Not Covered / Investigational
NMES devices billed under HCPCS E0744 for scoliosis are not covered (investigational) due to insufficient evidence in peer‑reviewed, published medical literature demonstrating safety and clinical efficacy for treatment of scoliosis.
Definitions
Background
Neuromuscular electrical stimulation (NMES) delivers electrical impulses through electrodes placed on the skin over targeted muscle groups to elicit muscle contractions. The primary clinical purposes are to strengthen weakened muscles and to prevent or treat disuse muscle atrophy when nerve supply to the muscle is intact. Coverage decisions in this policy follow the state definition of medical necessity and require that clinical documentation demonstrate that the targeted muscle has an intact nerve supply and that atrophy is due to a non‑neurologic cause, with no manufacturer‑listed contraindications present.
