That is a good question and I do not see a specfic number anywhere on the CMS website. It may be helpful to have the patient complete an ABN form after you have notified them that Medicare may not pay for the visit and the cost of the visit. In this case if Medicare does not pay for the visit, you have informed the patient ahead of time and they are responsible for the visit. Just a thought.
[I have to agree with Jsmith - The ABN will protect the practice for reimbursement if MDCR decides the visit is pt responsibility. Remember the overarching element: is it medically necessary]
I would also suggest this information be a part of a 'sit-down' with a Clt/Pt that is showing up insisting on being seen "nearly every other day".
Perhaps if they can either bring a more comprehensive 'basket of information' to the session with a provider (as in: writing a list of all concerns, to be reviewed when seen) then the session might be a more fruitful mtg for all?
OR, in the case of someone whose needs might be more psychological in nature (needing reassurance, hypochondria-based, etc?), the awareness that they will be financing additional sessions from their own pocket might be a mitigating factor toward whether or not they show up again "the day after tomorrow"??
