Billing Reference Guide

  • Zynex will invoice your insurance company for the MSRP of the device, and any monthly treatment supplies that are shipped. MSRP amount is simply a list price, and your insurance company will process and reimburse the claim according to their reimbursement schedule, if approved.
  • Each insurance company will process claims based on your individual coverage. After they receive the claim, your provider will determine their “allowed amount” for the device and will send you an Explanation of Benefits (EOB). This document will identify any deductible or coinsurance amounts that you may be responsible for. This is not a bill from Zynex Medical.
  • If your insurance denies the claim or indicates that the claim will go towards your deductible, please contact us so that we can review the claim with you. Together, we can discuss the best option for you as the patient. Options may include:
    1. Zynex Medical working with you to appeal the denied claim
    2. Working with you to find payment terms and options that are affordable
    3. Returning the device to Zynex Medical. If you choose to return the device, there will be a fee applied to your account for the time the device was in your possession, as well as a charge for any supplies you received.
  • If you have ordered an electrotherapy device, to aid in your treatment you may be receiving monthly supplies of electrodes and/or batteries. These supplies will be billed to your insurance. If at any time you would like to suspend these monthly shipments, please contact a Patient Support Representative.
  • Zynex representatives are available to answer any questions you have, review the billing process, and discuss your insurance coverage, including coinsurance and deductibles. You can contact a Patient Support Representative at 1-800-495-6670 or connect with us on our Live Chat by going to between the hours of 6 a.m. and 6 p.m., Mountain Time. Or, if you prefer, you are welcome to email us anytime at [email protected] so that we can assist you


If you have a secondary insurance, please call your primary insurance provider and request that they set up a Coordination of Benefits. You may also provide Zynex with an Explanation of Benefits from your primary insurance so that we can submit the claim to your secondary insurance. Please submit the EOB as quickly as possible so that we can establish correct billing on your account.

If you are using one of our electrotherapy devices, your device requires the use of monthly supplies, including electrodes and batteries. For effective treatment, the electrodes must be replaced when they no longer completely adhere to the skin.

No. An EOB is an explanation of the amount that your insurance company allows for the device and supplies, and how much they have paid. You can contact Zynex for a copy of your bill at any time. If you have questions, or if your insurance company denies the claim, please contact us at 1-800-495-6670 so that we can discuss your options.
