§416.45(a) Standard: Membership and Clinical Privileges
Members of the medical staff must be legally and professionally qualified for the
positions to which they are appointed and for the performance of privileges granted.
The ASC grants privileges in accordance with recommendations from qualified
medical personnel.
Interpretive Guidelines §416.45(a)
All members of the ASC’s medical staff and all clinicians granted medical staff
privileges must be appointed to their position within the ASC by the ASC’s governing
body. They must be granted privileges by the governing body, in writing, that specify in
detail the types of procedures they may perform within the ASC. It is not sufficient for
the governing body to grant privileges to “perform surgery” or even to perform
“orthopedic surgery.” For example, an ASC that specializes in orthopedic surgery of
various types must specify which types of procedures each surgeon is privileged to
perform.
The ASC’s governing body must assure that medical staff privileges are granted only to
legally and professionally qualified practitioners.
“Legally qualified” means the practitioner has a current license to practice within the
State where the ASC is located, and that the privileges to be granted fall within that
State’s permitted scope of practice. The ASC must verify that each practitioner has a
current professional license and document the license in the practitioner’s file.
“Professionally qualified” means that the practitioner has demonstrated competence in
the area for which privileges are sought. Competence is demonstrated through evidence
of specialized training and experience, e.g., certification by a nationally recognized
professional board.
The governing body is also required to solicit the opinion of qualified medical personnel
on the competence of applicants for privileges. The recommendation provided must be in
writing, and should include a supporting rationale. The qualified medical personnel may
be current members of the ASC’s medical staff, but may also be physicians not practicing
in the ASC. ASCs should consider seeking the recommendations of qualified outside
physicians when they do not have appropriate expertise in-house to evaluate the
competency of an applicant for privileges. This is particularly advisable when the ASC’s
governing body consists of one physician owner who is also the sole member of the
medical staff. The ASC’s governing body is not required to accept the recommendation
provided by the qualified medical personnel to grant, deny, or restrict privileges to a
practitioner. However, when the ASC’s governing body makes a decision contrary to the
recommendation, it is expected to document its rationale for doing so.
The ASC should document the process by which the governing body grants medical staff
privileges, including the documentation, or credentials, it reviews for each candidate, the
criteria it uses in evaluating the candidate, how it selects the qualified medical personnel
who make recommendations on the practitioner’s qualifications, and whether and under
what circumstances the governing body may make a privileging decision contrary to the
recommendation of the qualified medical staff.
Survey Procedures: §416.45(a)
• Ask the ASC’s leadership to explain its process for granting clinical privileges.
• Review a sample of files to verify medical staff have been granted clinical
privileges.
There must at a minimum be documentation of:
o State licensure, registration, or state certification, as applicable;
o Certification by a specialty organization, as appropriate;
o Other training or pertinent experience;
o Evidence of a recommendation by qualified medical personnel
concerning the practitioner’s competence;
o The scope of the privileges granted to the practitioner; and
o If the governing body granted privileges against the recommendation
of the qualified medical personnel, its rationale for doing so.
• Does the review of each practitioner’s record provide evidence that they are
legally and professionally qualified to exercise the privileges granted them by the
ASC?
