Insurance Reimbursement for Biofeedback and PEMF: What Practitioners Should Know
This page reports publicly published coding and coverage information. It is not billing, coding, or legal advice, and it is not a statement that any BioReg device qualifies for any code. Codes and coverage change. Verify current payer policy and work with a certified professional coder before submitting claims.
There is no CPT code for PEMF therapy. Where a practitioner bills insurance in connection with a session, the billable service is biofeedback training, and a Medicare Administrative Contractor billing and coding article describes that as a service in which feedback results are used or analyzed by the patient or clinician. Device capability alone does not establish that such a service occurred.

Is PEMF therapy covered by insurance?
There is no CPT code for PEMF therapy. Where a service delivered in connection with a BioReg device is billable, the billable service is biofeedback training, not the delivery of a magnetic field. Equipment and supplies used during a professional service are not separately billable simply because they were used.
Coverage of biofeedback itself is narrow under Medicare and varies among commercial payers. Medicare's national policy is National Coverage Determination 30.1, Biofeedback Therapy, summarised on the Medicare coverage page.
What makes a biofeedback service billable?
A Medicare Administrative Contractor billing and coding article describes biofeedback training as the time the modality is attached to the patient, with feedback results used or analyzed by the patient or clinician (Billing and Coding Article A53352). That article is jurisdictional guidance, not national policy.
Whether device architecture alone establishes that a billable biofeedback training service occurred is an open question. It is a determination that depends on the professional service actually delivered and documented, and it should be made with a certified professional coder. BioReg does not answer it here.
How are BioReg devices built?
BioReg device architecture
The BioReg CellCom uses input channels that obtain information from the user and can modify therapeutic output in response. The BioReg Nesta line, comprising the Nesta Child, Nesta Metabalance, Nesta Pro Home, Nesta Pro Complete, and Nesta Pro Premium, is open-loop: these devices deliver a field and perform no physiological measurement and no feedback.
BioReg does not represent that use of any device establishes that a billable biofeedback service was performed. That determination depends on the professional service actually delivered and documented, and it should be made with a certified professional coder.
Have practitioners been paid for these services?
Yes. BioReg is aware of paid claims from multiple practitioners for biofeedback services delivered in connection with CellCom use.
Payment of a claim is not the same as established coverage. Payers adjudicate and pay claims that they may later review, and previously paid claims can be recouped. Outcomes varied by payer, plan, state, provider license type, and diagnosis, and none of those variables carries over to another practice.
BioReg does not represent that any device qualifies for any code, or that any practitioner will be paid. Verify your payer's medical policy and work with a certified professional coder before submitting claims.
Which biofeedback codes are current, and which were deleted?
Several codes still circulating in biofeedback training materials no longer exist. CPT 90911 was deleted effective 1 January 2020 and replaced by CPT 90912 and add-on +90913, and the health and behavior assessment codes 96150 through 96155 were deleted on the same date (CY 2020 Physician Fee Schedule final rule). CPT 90806 was deleted effective 1 January 2013 (CY 2013 Physician Fee Schedule final rule).
See the full deleted-code table and the current biofeedback code family.
Does Medicare cover biofeedback?
Medicare's national coverage of biofeedback is limited to muscle re-education of specific muscle groups, or treatment of pathological muscle abnormalities such as spasticity, incapacitating muscle spasm, or weakness, where more conventional treatments have not been successful. It does not cover biofeedback for ordinary muscle tension states or psychosomatic conditions (NCD 30.1). CPT 90875 and 90876 are identified as non-covered (Billing and Coding Article A56937).
Read what Medicare covers for biofeedback therapy.
Why do biofeedback claims get denied?
Deleted codes, services outside the payer's published policy, documentation that does not establish the service occurred, missing session time on timed codes, and unbundling are the recurring causes. A dedicated page on denial causes is in preparation and will be linked here when it publishes.
What documentation do payers look for?
Published guidance points to the physiological parameter actually measured, the feedback produced, how that feedback was used or analyzed, the training activity, medical necessity tied to a documented diagnosis, and session time where a timed code is reported. A dedicated documentation page is in preparation. BioReg does not supply note templates or example documentation language.
When is cash-pay the better model?
Given narrow Medicare coverage and variable commercial policy, many practices run biofeedback and PEMF services on a cash-pay basis. A dedicated page on cash-pay models is in preparation. To model session volume and device cost for your own practice, use the ROI calculator.
How often does this information change?
CPT codes change annually, effective 1 January. NCCI edit files are updated quarterly. ICD-10-CM updates annually, effective 1 October. Any reference document without a review cycle goes stale.
