Summary
This is a fresh policy update confirming that Interferential Current Stimulation (IFS) remains classified as investigational and is not covered by insurance. The policy provides comprehensive billing codes that should not be used for reimbursement claims, with specific guidance on correct coding for interferential stimulators.
Action Required
Immediately: Billing team must ensure all interferential current stimulation services are marked as non-covered/investigational in billing system. Update encounter forms to alert providers that IFS procedures (CPT 20974, 97014, 97032, HCPCS E0745, G0283, S8130, S8131) will not be reimbursed. Use correct code E0745 instead of E1399 for interferential stimulators. Claims for these services will be denied as investigational.
