Physician Assistants/Nurse Practitioners

Physician Assistants (PAs) and Nurse Practitioners (NPs) are licensed health care professionals who practice as part of your medical team in all areas of medicine, with physician supervision.

In most states, Maine included, PAs and NPs can treat patients and write most prescriptions when their supervising physician is away. This helps to maintain continuity of care when doctors are unavailable. They are trained to recognize when patients need the attention of a supervising physician or another orthopedic specialist.

Their training is modeled after medical student training, to include anatomy, pharmacology, pathophysiology, clinical medicine, and physical diagnosis and treatment.  This is followed by clinical rotations.

How do physicians and PAs/NPs work together?
The relationship between a PA/NP and his/her supervising physician is that of mutual trust and respect; they function as a team. The PA/NP is a representative of the physician and treats patients in the style and manner developed and directed by the supervising physician.

What can they do?
Physician assistants and nurse practitioners provide a broad range of medical and surgical services, which have traditionally been performed by physicians. PAs and NPs are trained to conduct physical examinations, diagnose illnesses, order and interpret x-rays and laboratory studies, write prescriptions, assist in surgery, develop treatment plans, and instruct and counsel patients.  They also treat injuries by suturing, splinting, and casting. Additionally, PAs and NPs may assist in surgery. These providers may see patients independently and/or directly with a physician.

When might I see a PA/NP at OA?
At the time of:

  • Initial visit
  • Follow-up Care
  • Preoperative Visit
  • Emergency Room Visit
  • Cast Room Visit
  • Hospitalization
  • Surgery, in the Operating Room

You may see the physician and his/her PA/NP at the same visit. However, if you do not see the physician, please know that the physician assistant or nurse practitioner discusses and reviews your case with his/her supervising physician.

Will my insurance pay for me to see a PA?
It is usual and customary for insurance to cover services rendered by a physician assistant and nurse practitioner.
