Signature card on file
I am not sure I really understand your question.
Every note - if it is to be billable - has to be signed by the provider. The signature SHOULD be legible, but let's face it ... how many are.
Therefore, we are allowed to have a signature card on file so that ANN E DOCTOR, MD has signed the card and uses the same signature on notes - the signatures can be compared and the coder/biller has some assurance that this provider actually provided the service.
In our practice, our dictation system assigns a unique # to each provider. We ask them to add their provider number (5 digits) along with their signature. That number is usually MUCH clearer and, because it is unique to each provider, clearly lets us know who is signing (even if we can't really read the signature).
Hope that helps.
