Cala Trio is not currently covered by Medicare or private insurance. Insurance coverage for Cala Trio will take at least one year and we are working hard to keep that time frame as short as possible. During this time, it is very important to Cala Health's mission to make essential tremor therapy accessible to consumers. Our guiding principle and primary goal is to have as many people as possible have access to and be able to consider Cala Trio therapy to manage their hand tremor.

Notice to Medicare Beneficiaries

Medicare will pay for medical equipment and supplies only if a supplier has a Medicare supplier number. We do not have a Medicare supplier number, therefore Medicare will not pay for any medical equipment and supplies we sell or rent to you. You will be personally and fully responsible for payment.

Notice to VA Beneficiaries

Cala Trio can be available upon submission of a prescription by your Veterans Health Administration (VHA) health care provider. Ask the VHA to consider Cala Trio for you with these two steps:

  1. Provide your VA Health Care Provider with the Doctor Discussion Guide.
  2. Ask the VA Prosthetics Department to email for ordering information.
