Coverage criteria and billing rules

Coverage and billing are subject to coding rules, documentation, site of service, and authorization requirements. Specific details:

Bill HCPCS E0762 for the transcutaneous electrical joint stimulation device

Bill HCPCS A4595 as a monthly supply allowance that includes electrodes (any type), conductive paste or gel if needed, tape or other adhesive if needed, adhesive remover, skin preparation materials, batteries (single use or rechargeable), and battery charger (if rechargeable); one unit of A4595 = one month; separate billing for individual supplies is considered unbundling

Use HCPCS A4465 only for replacement of wraps/straps used to position and hold electrodes used with TEJSD; do not use A4465 for replacement of brace wraps/straps

Use one unit of A4557 for lead wires going to two electrodes

Apply modifiers per CMS NCCI and standard billing guidance; modifiers should be applied only when supported by documentation; incorrect modifier application may result in denials

Coverage will be considered when services are furnished in an appropriate setting to the patient’s medical needs and condition; authorization may be required

For Medicare indications that do not meet NCD, local LCD, or a specific medical policy, complete a Pre‑Service Organization Determination (PSOD)

Complete and thorough documentation in the medical record is required to substantiate services; failure to document may result in denial or recoupment

An authorization is not a guarantee of payment; proper billing, coding, and adherence to policy are required and Priority Health may perform pre- or post-claim payment integrity reviews, deny, reject, or recover payments when guidelines are not followed

CMS and MDHHS guidelines apply unless otherwise specified; where such guidance is absent this policy applies

Priority Health may perform pre- or post-claim payment integrity reviews; failure to follow coding, billing, policy, or contractual guidelines may result in claim rejection, denial, or recovery of payment. Authorizations do not supersede coding, billing, or reimbursement requirements.

Priority Health may recover payments or deny claims if guidelines aren't followed

Documentation Required

Documentation requirement

The provider is responsible for maintaining complete, accurate, and thorough medical record documentation to substantiate the procedures, visits, DME, supplies, and services billed. Documentation must support the CPT/HCPCS/revenue codes submitted and the medical necessity of the service. Failure to document services rendered to the highest level of specificity will result in denial.

Maintain full medical record documentation supporting the service and codes billed
Document medical necessity, procedure details, dates of service, and any applicable clinical rationale
Consult any specific documentation requirements in applicable guidelines or the Provider Manual
