contacting medicare for pre-authorization ?

@thumper1, Yes, IF there is a need for pre-authorization, it is handled by the providers. What my concern was what if the service was not covered and the patients found out after the fact. In my pre-medicare days and with the financial responsibility a patient signed, a patient will be responsible, hence I think a patient will have to make sure the procedure is authorized. May be I should use “covered” instead of “authorized”. But given what I found out about ABN here, it is moot.

@calmon and @JazzyTXMom thanks.
