ENT Credentials 101
What “FACS” and “FAAO-HNS” Actually Mean

Today’s patients are smart and are no longer just passive participants in their health. Part of being an active participant in anything concerning their health is taking the time to carefully research and consider potential ENT care providers, and an important part of this process is checking, verifying, and comparing credentials and qualifications.
This guide from Palm Springs Breathe Free can help patients in Palm Springs, CA, understand the basics of ENT credentials, such as FACS and FAAO-HNS, and what they mean for the quality of care they get.
What Is FACS?
In medicine, FACS stands for “Fellow of the American College of Surgeons” and is a professional fellowship designation. It further signifies that a medical surgeon has passed membership requirements (such as board certification in their field of specialty, peer review, professional qualifications, and ethical standards) as set by the American College of Surgeons(ACS), which is a professional society for surgeons practicing in the United States.
An FACS professional fellowship designation indicates that a surgeon is in good standing with the ACS. It does not, however, signify board certification.
Furthermore, an FACS fellowship tells patients that a surgeon:
- Has completed accredited surgical training in their field of medical specialty
- Has been peer-reviewed and accepted into the ACS
- Has met board certification requirements in their field of specialty (such as board certification in Otolaryngology – Head and Neck Surgery), which is a requirement for FACS eligibility
- Demonstrates commitment to ongoing education and training on ethical practice and standards of medical care
What Is FAAO-HNS?
In ENT medicine, FAAO-HNS stands for “Fellow of the American Academy of Otolaryngology – Head and Neck Surgery” and is also a professional fellowship designation. It indicates that an ENT specialist has a good standing membership with the American Academy of Otolaryngology – Head and Neck Surgery (AAO-HNS), which is the main professional organization for ENTs practicing in the United States.
Like FACS, an FAAO-HNS fellowship indicates membership with a professional society, but does not signify board certification.
An FAAO-HNS fellowship tells patients that an ENT:
- Has completed accredited specialty training in Otolaryngology
- Is in good standing with the AAO-HNS
- Has met membership requirements as set by the AAO-HNS, which is separate from board certification requirements
- Demonstrates a commitment to continuing education and ongoing professional involvement in the field of otolaryngology, as well as continued professional engagement and participation in their field of specialty
What Is the Difference Between FACS and FAAO-HNS?
Here’s a quick overview of the major differences between FACS and FAAO-HNS:

Moreover, here are a few more key differences between FACS and FAAO-HNS:
- Both the FACS and FAAO-HNS are voluntary memberships to professional organizations.
- Neither the FACS nor the FAAO-HNS signifies board certification.
- An FACS professional fellowship designation encompasses all medical specialties (including ENT medicine), while an FAAO-HNS professional fellowship designation indicates professional involvement in the field of ENT medicine.
- FACS reflects a medical surgeon’s adherence to the ACS’s professional and ethical membership standards, while FAAO-HNS reflects an ENT specialist’s good standing membership with the AAO-HNS.
Board Certification in Otolaryngology – Head and Neck Surgery: A Highly Recognized ENT Credential
While it’s fairly common for many ENT specialists to have both the FACS and FAAO-HNS designations attached to their names, another highly recognized ENT credential is board certification in Otolaryngology – Head and Neck Surgery.
✅ Board certification in Otolaryngology – Head and Neck Surgery is a voluntary credential, unlike a medical license, which is a legal requirement to practice medicine in the United States.
✅ It indicates that a certain ENT care provider has completed specialty training, passed additional board certification requirements, and met industry-recognized professional standards, as set by the American Board of Otolaryngology – Head and Neck Surgery (ABOHNS), a nationally recognized certifying body for otolaryngologists practicing in the United States.
✅ Board-certified ENTs may choose to pursue further training in other subspecialties, such as complex pediatric otolaryngology, neurotology, and sleep medicine.
Commonly Asked Questions About ENT Credentials in Palm Springs, CA
What is the difference between a licensed physician and a board-certified physician?
In the United States, a physician must acquire a medical license in the state or jurisdiction in which they practice to legally provide medical services. Unlike a medical license, board certification is not a legal requirement, but rather a voluntary and additional credential they may choose to pursue, as it demonstrates expertise in their field of specialty.
All board-certified physicians, regardless of specialty, are licensed, but not all licensed physicians are board-certified.
Are ENTs and otolaryngologists different?
“ENT” and “otolaryngologist” both refer to the same medical specialist.
An otolaryngologist, simply known as an ENT, diagnoses and treats conditions affecting the ears, nose, throat, neck, and related facial structures.
“ENT” is the more widely used term because it’s easier to remember, but “otolaryngologist” is the official medical term used in most medical settings and recognizes that they treat more than just the ears, nose, and throat (ENT).
Are all otolaryngologists board-certified?
No, not all otolaryngologists are board-certified. Unlike a medical license, board certification is not required by law to practice ENT medicine in the United States.
