Your anesthesiologist takes several factors into account when recommending the type of anesthesia. Some of those factors include the type of surgery or non-operative procedure being performed and your medical history. These types of anesthesia are not always clearly defined, and patients may progress from one level of sedation/anesthesia to a lighter or deeper level during the procedure. For this reason, the American Society of Anesthesiologists (ASA) considers anesthesia a continuum, from light sedation to general anesthesia.


“Anesthesia Care Team”
Most anesthetics administered in Pennsylvania are provided using an “Anesthesia Care Team” model, with the anesthesiologist serving as the “director” of the anesthesia care team. Prior to surgery the anesthesiologist evaluates the patients’ current state of health and is responsible for designing the anesthesia plan taking into account the patient’s condition and the nature of the surgery.



  • Insurance Department Proposes Balance Billing Limits

    3/3/2016 On January 19, the Pennsylvania Insurance Commissioner released for comment draft legislation designed to "protect" consumers from "surprise balance billing”. This bill would limit out-of-network providers, including anesthesiologists, practicing in an in-network facility to billing patients only their co-pays and deductibles. Out-of-network physicians would then need to negotiate with the patient’s insurer to determine the remainder of their payment. This action follows a public hearing held last fall at which PSA and many others provided testimony.

The choice of anesthetic or sedation is made by a physician taking into account various factors, including but not limited to the procedure being performed and the general medical condition of the patient. General anesthesia may be administered by an anesthesiologist, a nurse anesthetist under the direct supervision of a physician, preferably an anesthesiologist, or in some states by an anesthesiologist’s assistant under the direct supervision of an anesthesiologist.

The Anesthesiologist’s Expanding Role
The Centers for Medicare and Medicaid Services (CMS) released a January 2011 update to their Interpretive Guidelines for the Anesthesia Services Condition of Participation for Hospitals. As a result anesthesiologists have assumed a leadership role in developing and implementing medical staff rules and regulations (bylaws) that define the qualifications and supervision requirements for many “categories of practitioners”, such as those providers performing “Moderate Sedation”, “Deep Sedation” or obstetrical “analgesia” services.
