Wow, what a great case study.
I am no JD, but my initial thought would be that since the patient initiated the disputed claim, they are giving permission for you to provide documents to support your response to the CC company. It should be reasonably expected.
I assume the only document needed would be the signed authorization to use the card. You wouldn't be supplying treatment records, just business records. Perhaps an addendum be added to the current authorization that states, that in the case of disputed claims, you will be supplying the CC company the signed authorization as proof...or something like that to cover you for releasing that document. And/or it should be added to the NPP if it is not covered already.
I am interested in hearing how this turns out and other's opinions because this would make a great case study for students.
