im not sure what you are asking here. You cannot bill for services you haven't provided. If you don't see the patient, you can't bill for it. There is one exception to this, but even this is a complicated. There is "incident to" billing where you can bill for another provider (e.g. NP, PA, clinical psychologist's) work as incident to your own, which allows you to collect 100% of the physician fee rather than 85%. But that applies only if you did the initial evaluation of the patient, and they then see the patient to follow up as part of the care, they are treating exactly the same problem as you were, you remain directly involved in the patient's care, and you are directly supervising the practitioner, meaning you are physically located in the office and available as needed. There is also the assumption that you may continue to see the patient but medicare does not provide any guidance on that or how often you might see them.
You could not do incident to billing if for new patients seen by NPs (i.e. you need to do all new patient evals in this model), and you cannot bill incident to for any new problems that emerge in the course of treatment. For example if you saw a patient with depression, dx MDD, and the NP then treats the patient for MDD for subsequent visits and you bill incident to, if the patient becomes manic at a later NP visit, this visit would need to be billed under the NP's NPI unless you personally evaluate the patient and document it.
The other issue with incident to billing is it is a medicare thing. Not all payors accept incident to billing so you would have to check this with each insurance plan. It varies considerable geographically.
Incident to billing would work well in certain scenarios. If you conducted the initial evaluations in an ADHD clinic, and referred all straightforward ADHD cases to the NP to follow up on, then those follow up visits could technically be billed incident to your services, provided that no new problems arise. For example if the patient became depressed, then if you did not see the patient, the NP would bill under their NPI as it is a new problem and would only capture 85% of the total physician fee. In a memory clinic, all dementia evals may be done by the physician, and the NP could then see the patient for more regular follow up visits billed as incident to your original services, with the physician seeing the patient annually.
The NP should be credentialed with all the insurance panels.
