Medicare does not have a National Coverage Decision (NCD) that provides guidance to Medicare Administrative Carriers (MACs) regarding coverage for 0525T. Each MAC provides coverage decisions based upon medical necessity and appropriateness and will review FDA approved indications for use. Providers should ensure that documented medical necessity of the Guardian System is documented for each patient. Always check with the local MAC to see if there are guidelines in place for coverage of 0525T.

For non-Medicare, or Commercial payors, coverage will be determined based upon medical necessity. This is typical for all new FDA approved medical devices. It is recommended that you confirm patient coverage prior to implant of the Guardian to avoid any payer coverage issues with private plans. During this time, Avertix provides support for patient coverage. This support is available to providers and patients at
