The doctor or therapist has the resources to determine what codes are to be used. Each insurance policy may have it's own rules about covered procedures and devices.

I would suggest getting a written treatment plan from your provider, complete with specific diagnosis, procedure name(s), name of any device and what it is intended to accomplish. Then contact your insurance company and ask how to proceed so that they will pay all or most of it. If you have a Medicare supplement, your coverage must follow Medicare rules and policies, which may be more or less than a regular policy.

Does this help?
