IAC Vascular Testing accreditation is the Intersocietal Accreditation Commission's program for noninvasive vascular testing laboratories, measured against the IAC Standards and Guidelines for Vascular Testing Accreditation, published August 3, 2026, with revised standards that take effect February 3, 2027. This page is for vascular testing laboratories and diagnostic practices seeking IAC accreditation or adding sites. Integral Healthcare Solutions (IHS) builds the vascular lab's policies and evidence controls for IAC accreditation; your physicians and technologists own testing and interpretation.

What is IAC Vascular Testing accreditation?
The IAC standard defines the facility: "A vascular testing facility is a unit performing noninvasive vascular diagnostic testing under the overall direction of a Medical Director. A Technical Director is appointed who is responsible for the direct supervision of all the technical staff and the daily operations of the facility" (IAC Standards and Guidelines for Vascular Testing Accreditation (August 3, 2026)).
The testing areas a lab can be accredited in are extracranial cerebrovascular, peripheral arterial, intracranial cerebrovascular, peripheral venous, visceral vascular and screening.
The governing texts:
- The IAC Standards and Guidelines for Vascular Testing Accreditation (August 3, 2026). The standard flags its own changes: "Standards that are highlighted are content changes that were made as part of the August 3, 2026 revision and become effective February 3, 2027. Facilities applying for accreditation after February 3, 2027 must comply with these new highlighted Standards."
- The IAC Vascular Testing Accreditation Checklist (updated 8-15-2025), which lists the documents the application must carry. The checklist is dated 8-15-2025, before the August 3, 2026 revision; confirm with IAC whether a newer checklist applies (your facility asks IAC; IHS can draft the question).
IAC's review: "The application review process generally takes approximately 8 to 10 weeks to complete, at which time the decision is provided to the facility" (IAC, Review Decisions).
Who needs it and what triggers it
- A lab seeking IAC accreditation for the first time, or renewing: "IAC application fees cover each three-year accreditation cycle" (IAC, Vascular Testing).
- A facility "applying for accreditation after February 3, 2027," which IAC says must comply with the highlighted standards from the August 2026 revision (IAC Standards and Guidelines for Vascular Testing Accreditation (August 3, 2026)). IAC's text does not say whether a renewal application counts or which version applies to a filing made before that date and decided after it. IHS reads "applying" as the filing date; that is IHS's reading, not IAC's.
- Growth across sites. IAC prices sites 2 and up on a separate per-site scale (IAC fees), so a multi-site lab plans its application by site.
- A vein center that relies on your lab: IAC's vein center standard requires venous duplex testing "in an IAC or American College of Radiology (ACR) accredited facility" (IAC Vein Center Standards, May 2026).
How IHS helps
- A gap assessment against the IAC Vascular Testing standards, including the August 2026 changes that take effect February 3, 2027, using questionnaires on staff, equipment, exam and report workflow and multi-site setup.
- Document and evidence mapping: a crosswalk from each checklist item to the record that meets it.
- Drafted qualification and equipment controls, exam and report workflow procedures and QI records, with technical protocols drafted for your medical director to review and approve.
- A mock review of the submission.
- Readiness support while you assemble case studies.
What you supply: the IAC standards, credential files, equipment records, case studies, and your vascular physicians and technologists.
The limit: testing technique and interpretation are clinical work. Your lab submits the application; IHS does not submit to IAC or correspond with IAC on your behalf.
What to have ready
Items cite the IAC Vascular Testing Accreditation Checklist (updated 8-15-2025) unless noted.
- A named Medical Director and Technical Director, as the IAC Standards and Guidelines for Vascular Testing Accreditation (August 3, 2026) defines the facility.
- The testing areas you will apply for, from the six the standard lists.
- A CME record for every staff member: "All staff are required to have 15 hours of CME relevant to noninvasive vascular testing every 3 years. Physicians must document 15 hours of AMA Category 1 CME."
- Credential information for technical and medical staff. The checklist lists "RVT, RVS, RT(VS), RPhS, CRVS [Canada only] for technical staff, RPVI for medical staff ... RPNI for physicians." It adds: "Additional credentials may be accepted for specific testing areas, refer to the Standards for complete details."
- Case studies: "Facilities must submit three abnormal cases from the previous 12 months."
- QI meeting minutes: "Prepare minutes from a minimum of two QI meetings per year."
- Written protocols: "Facility-Specific, Step-by-Step Technical Protocols: For all modalities the facility is applying for accreditation."
- A site list, if you run more than one location, to match IAC's per-site fee scale (IAC fees).
- If you will apply after February 3, 2027, a check of your policies against the highlighted standards in the IAC Standards and Guidelines for Vascular Testing Accreditation (August 3, 2026).
If most of this is in place, the introductory call is the place to start.
How it compares
| Route | What the sources say |
|---|---|
| IAC Vascular Testing | Six testing areas under the August 2026 standard; three-year cycle; review in about 8 to 10 weeks (IAC; IAC). |
| ACR Ultrasound | ACR lists Ultrasound among its accreditation modalities (ACR), and IAC's vein center standard accepts duplex testing in an ACR-accredited facility. We did not review the scope of ACR's program for vascular testing. |
| Credentialed staff without facility accreditation | We did not review Medicare LCD language on whether credentialed sonographers or physicians can stand in for lab accreditation, so this page makes no statement on it. |
| No accreditation | CMS excludes ultrasound from the MIPPA advanced diagnostic imaging accreditation requirement (CMS). Other payer rules were not part of our review. |
This page does not recommend one route over another. The choice belongs to your organization.

What it costs
IAC publishes its Vascular Testing fees: a "$1,800 application base fee (includes one testing area/module)," "$300" per additional testing area over one, "$1,460" per site for sites 2-3, "$1,195" per site for sites 4-10 (a 20% discount), "$1,015" per site for each site over 10, and an expedited application at an "additional $3,000." "Application fees apply to three-year accreditation cycle" (IAC Vascular Testing program fees). Verify current fees with IAC.
IHS scopes each engagement after a free introductory call.
What this is not
- IHS is not an accrediting body and does not grant, influence or predict an IAC decision.
- IHS does not perform or interpret vascular tests or set scanning technique. IHS drafts; your lab submits.
- This page is not legal or clinical advice, and it does not state what a Medicare contractor or payer requires.
