Article 28 clinic- Overseeing doctor Clarification

Best answers
We currently have a provider based clinic, Article 28 that provides behavioral health services. We are located in NY and there is some confusion on who should be billed out on the claim when it comes to Medicare. We do not bill with place of service 11, as this is hospital outpatient. The doctor is onsite during all visits but doesn't always see the patients. We have counselors that see the patients when the doctor does not.
So if a patient comes in and sees a counselor can we have the overseeing physician on the claim form seeing that she, the MD, oversees the treatment plan, co-signs every note even when the counselor sees the patient and reviews/updates treatment plan as needed?

Right now we do not bill these professional fees out due to the conflicting thoughts surrounding the issue. Any help would be appreciated.
