RhMSUS Recertification Update 2024
Current recertifications are on hold as the ACR works with Meazure Learning on creating and maintaining an operable site for recertification. Currently, we do not have a date that the site will be open to accept recertification applications but will notify those eligible for recertification as soon as it becomes available. This means if you are due or past due for recertification, your RhMSUS certification will continue.
Frequently Asked Questions About RhMSUS™
Musculoskeletal Ultrasound Certification in Rheumatology™ - RhMSUS™ is a professional certification for physicians, physician assistants, and nurse practitioners who perform ultrasound as part of their practice in rheumatology. The RhMSUS™ credential signifies that an individual has passed the RhMSUS™ certification.
RhMSUS™ is a voluntary program and is not required for using musculoskeletal ultrasound in your practice. It is however, expected that achieving RhMSUS™ certification will become increasingly important in the future for reimbursement from Medicare and third party payors.
RhMSUS™ certification is valid for ten years. Recertification is required at ten-year intervals effective as of the date of RhMSUS™ certification. Recertification requirements are outlined in the Candidate Handbook.
RhMSUS™ has been approved as a pathway to payment for rheumatologists by Humana/HealthHelp. When a rheumatologist bills Humana for ultrasound, HealthHelp automatically sends a fax with instructions to electronically submit evidence of certification or training. Since RhMSUS™ is an approved program, designees just need to upload documentation of their certification. There have been no recent complaints regarding payment for musculoskeletal ultrasound.
If you are having issues with reimbursement for musculoskeletal ultrasound claims, please fill out the Health Plan Complaint Form and the ACR will do its part to assist you.
The RhMSUS™ program is open to ACR members and ACR non-members. There are four pathways for eligibility which are detailed in the Candidate Handbook.

Yes, certification is voluntary and there are no current legal requirements for you to use musculoskeletal ultrasound in your practice. As payors/insurers and institutions may have their own credentialing requirements for its physician and health professionals to use musculoskeletal ultrasound, it is expected that the RhMSUS™ certification will become increasingly important.
Certification is a voluntary process through which an organization grants recognition to an individual after verifying that he/she has met minimum criteria and in some cases passed an assessment.
Accreditation is a voluntary process through which an organization grants recognition to an organization, system, or program after verifying it has met minimum criteria which may include (but are not limited to) demonstration of compliance to established performance standards through submitted application and an onsite review process.
The ACR’s RhMSUS™ certification allows you (the individual physician, physician assistant, or nurse practitioner) to demonstrate your competency in musculoskeletal ultrasound in their practice in rheumatology.
The American Institute of Ultrasound in Medicine (AIUM) musculoskeletal ultrasound accreditation allows practices to demonstrate that they meet or exceed recognized standards in the performance and interpretation of diagnostic musculoskeletal ultrasound examinations.
The AIUM recognizes the RhMSUS™ certification as meeting the educational requirements necessary for accreditation as outlined in the AIUM’s Training Guidelines for Physicians and Chiropractors Who Evaluate and Interpret Diagnostic Musculoskeletal Ultrasound Examinations.
For those seeking both RhMSUS™ certification and AIUM accreditation, the ACR and AIUM offer a reimbursement of 20% off of the initial application fees. For more information, please contact us at education@rheumatology.org.
For you (the individual rheumatologist and PA or NP) working in rheumatology to have a way to demonstrate to patient, peers, payors, and the public that you are competent in using musculoskeletal ultrasound in your practice of rheumatology.
Based on feedback from the 2010 membership survey titled “ACR Musculoskeletal Ultrasound Certification Feasibility Study,” over 80% of the respondents said the ACR should offer MSUS certification for individual rheumatology healthcare providers. And 84% said they would elect to become certified if there was a program available in the U.S. The most influential reasons cited to become certified were:
- To enhance the effectiveness of treatment or diagnosis
- To learn completely new skills or knowledge
- To increase competence in current job
- To maintain or improve current skills or knowledge
- To keep up-to-date professionally
- Proof of competency to show payors/ insurers
- Expand services provides by the practice/institution
RhMSUS™ is the only musculoskeletal ultrasound certification program in the United States developed specifically for rheumatology practice.
RhMSUS™ was developed by the American College of Rheumatology for physicians, physician assistants, and nurse practitioners to demonstrate competency in musculoskeletal ultrasound in their practice of rheumatology. It only certifies that an individual is competent in their use of musculoskeletal ultrasound in rheumatology not their competence in rheumatology.
Physicians receive certification in the subspecialty of rheumatology through the American Board of Internal Medicine (in the United States, there are other boards outside the U.S.). Physicians who want to certify in and maintain their certification in rheumatology must still do so through the ABIM.
