Help please! We have a new physician starting in early August. The new physician will be graduating end of July. I've been told that the credentialing process cannot start until after graduation. If the new physician sees patients beginning in early August, can those visits be billed under an established, credentialed physician in our office? If so, is there a specific way to note this on the claim? Is there a modifier to use? Does the established, credentialed physician have to see the patient also and/or sign-off on the office note? If this is not appropriate, can you point me to documentation to give to the physicians? Our office has worked with a PA in the past but never a new physician straight from graduation. Any advice is welcome. Thank you in advance.
