The Registered Phlebology Sonographer (RPhS) credential is issued by Cardiovascular Credentialing International (CCI), and its published pricing is refreshingly simple compared with the surrounding costs most candidates overlook. The headline number is the examination fee. The real budget, however, includes documentation, continuing education, a possible retake, and the renewal obligations that start almost immediately after you pass.
This guide breaks down every cost category tied to the credential, using only figures published by CCI as of an October 15, 2026 review of its official pages. If you are still deciding whether the credential is worth pursuing, pair this article with our RPhS ROI analysis and the RPhS salary guide. For the eligibility side, see RPhS requirements.
The Examination Fee, Line by Line
The RPhS examination costs USD 365. That total includes a USD 100 non-refundable application-processing component. In practical terms, this means a portion of your payment is gone the moment your application is submitted, even if you are later found ineligible or decide not to test.
What You Are Paying For
The exam is computer-based and delivered at a Pearson VUE test center. Question formats include single-best-answer multiple choice, multiple response, image hot spots, and drag-and-place items. Candidates receive an on-screen calculator and an erasable board, may mark items for review, and can revisit questions within the remaining time. The exam is closed-book, and you must present two acceptable original IDs on test day.
Your result is reported on a scaled range of 0-900 with a passing score of 650. That is a scaled score, not a raw percentage, which is covered in detail in our RPhS passing score guide.
Hidden Costs of Proving Eligibility
CCI does not publish a separate fee for documentation, but gathering proof is not free. Every candidate needs a high-school diploma or GED plus one documented route, and each route demands route-specific verification of education, credentials, employment, or study counts.
| Eligibility Route | Core Requirement | 36 CEUs Required? |
|---|---|---|
| Active RVS/RVT | Six months of venous-ultrasound employment | Yes, in the preceding four years |
| Associate degree or 62 semester hours | Relevant education plus one year of experience | Yes, in the preceding four years |
| Bachelor's degree | Relevant degree plus six months of experience | Yes, in the preceding four years |
| Licensed physician associate/nurse practitioner | Six months of limited or complete venous-ultrasound experience | Not part of the route as published |
| Physician routes | Medical license plus study counts (150 or 200 studies, or residency/fellowship with 200 studies) | Not a universal requirement |
The 36 pre-application CEUs are not a universal requirement. If you are on one of the three routes that demands them, the cost of earning those credits is a real part of your total spend. Credits you already hold from your current employer or professional society may cover it, which lowers your out-of-pocket cost considerably.
Documentation and Notarization
Physician candidates submitting study-count letters must have them notarized. Notary fees vary by location and are usually modest, but they are an expense worth planning for. Candidates on other routes should budget time, and possibly small administrative costs, for obtaining transcripts, employer verification letters, and credential copies. CCI's supporting-documentation page lists what each route must supply.
What a Retake Costs You
Retakes are not discounted. A candidate who does not pass must submit a new application and pay the examination fee again. That means the USD 100 non-refundable processing component is charged a second time, and the full cost of a second attempt is the same USD 365.
CCI publishes a 75% first-time RPhS pass rate for 2025. That figure applies to first-time candidates in 2025, not to 2026 and not to all attempts, so treat it as context rather than a prediction. Our RPhS pass rate analysis and difficulty guide explain how to interpret it.
How the 2027 Testing Windows Affect Your Budget
Timing is a cost factor most candidates overlook. CCI is transitioning to a new scheduling model, and the details matter for anyone applying in late 2026.
- Applications received August 1-December 31, 2026 are assigned to the February 1-28, 2027 testing window.
- Effective February 1, 2027, testing occurs in February and August only.
- Earlier-approved candidates follow their ATT dates, capped at the end of February 2027.
This transition overrides the generic year-round, 90-day authorization language you may see elsewhere. For a failed attempt, it means the 45-day minimum retake interval is not the whole story: if you miss the February window, your next opportunity may be August. That can mean months of waiting, extended study costs, and delayed income from the credential.
Why the Matrix Version Matters
CCI publishes two Examination Matrices: the current one, in effect before February 1, 2027, and a separate matrix effective February 1, 2027. Both use the same five domain headings but with different weights. A new October 2026 applicant will sit the exam in February 2027 and therefore needs the February 2027 matrix, even though the domain lines below reflect the pre-transition scope. Studying from the wrong version is a quiet, avoidable way to waste a USD 365 attempt. See our RPhS exam dates guide for scheduling detail.
| Domain | Pre-Feb 2027 Weight | Feb 2027 Weight |
|---|---|---|
| Maintain Information, Facility, and Safety | 9% | 7% |
| Patient Diagnosis | 27% | 25% |
| Performance of Diagnostic Testing | 36% | 38% |
| Conservative Treatment/Therapy of Patients | 9% | 10% |
| Minimally Invasive and Invasive Treatment of Patients | 20% | 20% |
Note that the pre-transition published weights sum to 101% even though the issuer's total row says 100%; they are reproduced here exactly as published. For the full content breakdown, read our RPhS exam domains guide.
Renewal Costs: First Cycle and Beyond
Certification is not a one-time purchase. CCI structures renewal in two stages, and understanding it up front prevents surprises.
The Initial Certification Period
Your first certification period runs 9-12 months. First renewal costs USD 165, requires Code of Ethics compliance, and no CEUs are due. This is the cheapest renewal you will ever have, since you pay only the fee.
The Three-Year Cycle
After the first renewal, certification renews on a three-year cycle. Each renewal requires:
- The USD 165 renewal fee
- Code of Ethics compliance
- 36 CEUs, including at least 30 that are cardiovascular-related
Any remaining credits must be medical-related under CCI's dedicated CE policy. The credential page uses broader any-topic wording, but the more specific medical-related rule is the safer planning assumption, so do not count unrelated coursework toward your total.
CEU costs depend entirely on how you earn them. Employer-sponsored education, society meetings, and online courses range from free to substantial. Because 30 of your 36 credits must be cardiovascular-related, prioritize venous and vascular content you would want to learn anyway.
Cost Summary Table
| Cost Item | Amount | Notes |
|---|---|---|
| Examination fee | USD 365 | Includes USD 100 non-refundable application-processing component |
| Retake | USD 365 | New application and full examination fee required |
| First renewal | USD 165 | Ethics compliance; no CEUs due |
| Three-year renewal | USD 165 + 36 CEUs | At least 30 cardiovascular-related; rest medical-related |
| Pre-application CEUs | Varies | 36 CEUs in the preceding four years on three of the routes |
| Notarization | Varies | Physician study-count letters |
CCI's published pages do not list a separate fee for study materials, so the figures above are the official fixed costs. Everything marked "varies" depends on your route and your choices. For a single-attempt, no-retake scenario, the mandatory CCI payments through your first renewal total USD 530 (USD 365 plus USD 165).
Where to Spend Your Preparation Money
The cheapest attempt is the one you pass the first time, so the smartest budget decision is putting preparation dollars where the exam puts its weight. Performance of Diagnostic Testing carries the largest share at 36%, followed by Patient Diagnosis at 27% and Minimally Invasive and Invasive Treatment of Patients at 20%.
Performance of Diagnostic Testing (36%)
The heaviest domain deserves the largest slice of your time and money. Expect image-based items, including hot spots and drag-and-place formats.
- Venous ultrasound technique and protocol execution
- Recognizing normal versus abnormal venous findings on images
- Instrumentation and image optimization
Patient Diagnosis (27%)
Interpreting findings in clinical context separates passing candidates from those who only know technique.
- Venous disease presentation and differentiating conditions
- Linking sonographic findings to clinical significance
Minimally Invasive and Invasive Treatment of Patients (20%)
Often underestimated by candidates from purely diagnostic backgrounds, this domain tests procedural knowledge and the sonographer's role during treatment.
A Weighted Preparation Plan
If you use a structured plan, tie each week to domain weight rather than spreading effort evenly. A short, weighted timeline keeps spending focused:
Diagnostic Testing
- Drill image-based items and technique questions
- Confirm you are studying the February 2027 matrix if testing then
Patient Diagnosis
- Practice clinical-correlation scenarios
Treatment Domains and Safety
- Cover conservative therapy, invasive treatment, and facility/safety topics
- Take a timed run of 170 questions to rehearse the two-hour-50-minute pace
Our RPhS study guide and cheat sheet expand on this approach, and you can test yourself on the RPhS practice test site before spending USD 365 on a live attempt. A realistic practice score is the cheapest insurance against a failed first try, and the full-length practice exams mirror the multiple-response and hot-spot styles you will see.
Key Takeaway
Treat the USD 365 fee as the entry price, not the total cost. Budget for CEUs, documentation, the USD 165 renewal, and the real possibility that a missed window delays a retake by months. Practicing before you apply is the lowest-cost way to avoid paying the exam fee twice.
Frequently Asked Questions
The examination fee is USD 365, which includes a USD 100 non-refundable application-processing component. Retakes require a new application and the full examination fee.
The USD 100 application-processing component is non-refundable. Confirm the handling of the remaining balance with CCI directly, since policies can change and are covered in the Applicant Handbook.
First renewal is USD 165 with Code of Ethics compliance and no CEUs due. After that, each three-year renewal costs USD 165, requires ethics compliance, and requires 36 CEUs, with at least 30 cardiovascular-related.
Only on three routes: active RVS/RVT, relevant associate degree or 62 semester hours, and relevant bachelor's degree. Each of those requires 36 relevant CEUs in the preceding four years. Other pathways, including the physician routes, do not carry that requirement universally.
A general 45-day minimum retake interval applies, but the new testing windows constrain it further. With testing in February and August only starting in 2027, your next available date may be months away.
