A nurse can perform a 99211, but above that, a physician (PA, NPP, etc must perform/document/dictate the exam):
I am sure CMS has a page, but it did not pop up immediately.
Regulatory clarification
"In both the
Revisions to Payment Policies Under the Physician Fee Schedule for Calendar Year 2019 (PDF) (CMS, 2018) and an
additional FAQ (PDF) (CMS, 2018), CMS expanded current documentation policy applicable to office/outpatient E/M visits. Starting Jan. 1, 2019, any part of the chief complaint (CC) or history that is recorded in the medical record by ancillary staff or the patient does not need to be re-documented by the billing practitioner.
Instead, when the information is already documented, billing practitioners can review the information, update or supplement it as necessary, and indicate in the medical record that they have done so. This is an optional approach for the billing practitioner, and applies to the chief complaint (CC) and any other part of the history (HPI, Past Family Social History (PFSH), or Review of Systems (ROS)) for new and established office/outpatient E/M visits.
CMS notes that it has never addressed who can independently take/perform histories or what part(s) of history they can take, but rather addresses who can document information included in a history and what supplemental documentation should be provided by the billing practitioner if someone else has already recorded the information in the medical record.
The physician must still personally perform the physical exam and medical decision-making activities of the E/M service being billed."
"Under that system, the only Evaluation and Management (E/M) code that a Registered Nurse can bill to is 99211."
