Hi - My research shows that Medicare does not cover Camzyos under any of the "Plan Ds" since it is a Tier 5 formulary drug. This means that you only have your supplemental plan, if you have one, and Bristol Myers to help you with costs until this changes. Except for the folks in Canada, it seems like this is coming in somewhere between $17,000 and $25,000 - ish per year! During open season, we tried to get our supplemental insurance to tell us which of their plans would cover some of Camzyos which they would not do until we had a prescription and were working on pre-authorization - it was infuriating - so we were unable to choose what could have been the best supplemental plan to help us. This was United Healthcare. I hope others here will answer you - I don't completely know if I am correct or how much this varies from person to person.
