- The exam costs $325, and the required AMBA individual membership adds $99 per year, for an initial total of $424.
- The optional AMBA study guide lists at $199 and is not included in the $424 calculated total.
- Two retakes are included in the fee, though AMBA waiting and completion rules apply to them.
- Staying certified requires 15 CEUs per year, at least half through AMBA, plus continuous membership.
The Fee Stack: What You Actually Pay
The Certified Medical Reimbursement Specialist credential, issued through the American Medical Billing Association (AMBA) and its Certifying Board CBAMBA, has a refreshingly short fee structure compared with many professional certifications. There are only two mandatory line items at the start, and one optional purchase that most candidates should think carefully about.
| Cost Item | Amount | Required? |
|---|---|---|
| CMRS exam fee | $325 | Yes |
| AMBA individual membership | $99 per year | Yes |
| Calculated initial total (exam + membership) | $424 | Yes |
| AMBA study guide (regular price) | $199 | No, optional |
| Two retakes | Included in exam fee | Included, with rules |
The $424 figure is a calculated sum of the exam and the first year of membership. It deliberately excludes optional materials, so a candidate who also buys the study guide at the regular price is looking at roughly $623 before any other resources. For a broader look at how this fits into the whole picture, our CMRS certification cost breakdown covers the full pricing logic, and this article goes deeper on the mechanics behind each line.
Why Membership Changes the Math
Many certifying bodies treat membership as an optional perk. AMBA does not. Individual membership is a required component of the CMRS credential, and it is billed at $99 annually. That distinction matters in two ways.
Membership Is a Recurring Cost, Not a One-Time Fee
The $325 exam fee is paid once (retakes are included). The $99 membership renews every year, and AMBA's maintenance rules require you to keep membership active to keep the credential. Over a five-year horizon, membership alone accounts for $495, which exceeds the exam fee itself. Anyone budgeting for the credential should think in terms of an annual line item rather than a single purchase.
Membership Gives You the Student Environment
The exam is delivered through AMBA's online student environment, and no separately verified external testing vendor is listed. That means there are no proctoring-center fees, no travel, and no separate scheduling surcharge to account for. If you have seen other certifications that tack on testing-center fees, that category simply does not appear in the published CMRS fee structure. For how the logistics work, see our guide to CMRS exam dates and scheduling.
The $199 Study Guide: Buy or Skip?
AMBA sells an optional study guide at a regular price of $199. This is the single largest discretionary expense in the CMRS pathway, and it nearly equals the $325 exam fee in proportion. Whether it is worth buying depends on your background and on how the exam is structured.
When the Study Guide Makes Sense
Consider the guide if your gaps line up with the sections that carry the most required answers.
- You have never worked with ICD-10-CM or CPT coding and need structured exposure to both
- You are new to healthcare entirely and need Anatomy and Physiology (the largest section, with 82 required answers) built from scratch
- You want material written specifically around AMBA's 16 sections rather than general billing references
When You Can Reasonably Skip It
Because the exam is open book and spread across a 45-day window, experienced billers may find they can lean on resources they already own.
- You already work in claims, coding, or billing and know the CMS 1500 form well
- You hold current-year code books and can look up answers efficiently
- You are comfortable researching unfamiliar items such as managed care or insurance carrier rules
Our CMRS study guide walks through how to approach preparation with or without paid materials, and practice questions on the main practice test site can help you gauge whether you actually need the extra spend before committing $199.
Costs the Price Page Doesn't Advertise
The $424 headline number is accurate for what it covers, but a realistic budget needs to account for resources the fee does not include. None of these are mysterious; they are simply easy to overlook.
Current-Year Coding Resources
The current public outline for the exam is undated, and AMBA requires or directs candidates to current-year coding resources. For an exam with dedicated ICD-10-CM Coding and CPT Coding sections, the code books themselves are a real expense that sits outside the exam fee. Because the exam is open book, having accurate, current references is not just helpful; it is functionally part of your testing toolkit. Budget for these separately, and confirm with AMBA which editions they expect.
Time as a Cost
With 694 required answers across 16 sections, the exam is large. Unlike a continuous timed sitting, it is completed over a 45-calendar-day window after enrollment. That flexibility is valuable, but the 694 answers still represent hours of lookup, reading, and entry. If you are unpaid during study time or taking time off work, that opportunity cost can exceed the cash fees.
Optional Practice Materials
Beyond the official guide, some candidates add third-party question banks. These are entirely optional. If you do, choose ones aligned to AMBA's section names rather than generic billing content.
What the Two Included Retakes Are Worth
Two retakes are included with the exam fee, and this is among the most financially significant features of the CMRS pricing model. On many credentials, a failed attempt means paying the full fee again. Here, a candidate has up to three total tries covered by a single $325 payment.
There is an important caveat: the retakes are subject to AMBA waiting and completion rules. You should not assume you can immediately restart the moment you fall short. Confirm the exact timing and conditions with AMBA before you begin, so a retake does not collide with your 45-day completion window or your work schedule.
The passing standard is 85% cumulative, which is a high bar. Understanding where that bar sits is central to deciding how much preparation to buy. See our breakdown of the CMRS passing score and the discussion in how hard the CMRS exam is for context on what an 85% cumulative standard demands in an open-book format.
Key Takeaway
The included retakes lower your financial risk, but they do not lower the 85% cumulative standard. Treat them as a safety net, not a plan. Preparing well for the first attempt remains the cheapest path.
How the 45-Day Open-Book Format Affects Your Spend
The structure of the exam shapes how much preparation money you actually need. The exam is online and open book, includes a Case Study section, and is completed within 45 calendar days of enrollment rather than in one timed session. Complete item-type and scored versus unscored breakdowns are not publicly specified, so candidates should not assume a particular question mix.
Open Book Reduces Memorization Costs, Not Research Costs
Because you can consult references, you may spend less on flashcards or memorization tools. But you still need to find answers fast and accurately. The investment shifts from memorization toward having the right references on hand and knowing where to look in each of the 16 sections.
The Clock Starts at Enrollment
Your 45 days begin after enrollment, so enrolling before you are ready can waste part of a window you have already paid for. Sort out your references and set aside blocks of time first, then enroll. The mechanics of when to register are covered in our exam dates and scheduling guide.
No Eligibility Course to Buy
There is no mandatory course and no fixed work-experience hours verified for the credential. The main credential page lists a high school diploma or equivalent and membership, while the Rules and Requirements page states there are no prerequisites. Because those two pages differ slightly in wording, confirm directly with AMBA. Either way, you are not obligated to purchase a prerequisite training program, which keeps the entry cost low. Full eligibility details are in our CMRS requirements guide.
Budgeting Your Prep Time Across the 16 Sections
AMBA publishes 16 official section labels but no official percentage weights. The one hard number available is the count of required answers per section, and Anatomy and Physiology has the largest at 82. That is a count of required answers, not an officially stated scoring weight, so do not treat it as a guaranteed share of your score. Still, it is a reasonable signal for where preparation time will be spent.
The following is the single study-planning section in this article, tied to how the sections cluster. A practical way to spend prep hours and money is to group the 16 sections into themes:
Foundations
- Anatomy and Physiology (the largest published answer count at 82)
- Medical Terminology
- Acronyms and Terms in Common Healthcare Use
Coding Core
- ICD-10-CM Coding
- CPT Coding
- CMS 1500 Claim Form
Payers and Process
- Insurance and Insurance Carriers
- Managed Care
- EDI Transactions and Clearinghouses
Rules, Systems, and Application
- Compliance and HIPAA, and Fraud and Abuse
- Information Technology and Computers; Web and Information Technology
- General, then the Case Study to pull everything together
Where you spend money should follow this map. Coding blocks justify current code books; foundation blocks may justify the study guide if you are new to the field. The exact names and layout of all 16 sections are explained in our guide to the CMRS exam domains.
One Common Misreading to Avoid
AMBA mentions 85%, 10%, and 5% figures, but these describe reference sources, not domain weights. Do not use them to decide how to split your study hours or budget. Allocate time by your own gaps and by the published answer counts.
- 85% cumulative is the passing standard
- The 85/10/5 figures relate to reference sources
- No official percentage weights exist for the 16 sections
Year Two and Beyond: Maintenance Costs
The initial $424 is only the beginning of the financial commitment. Maintaining the credential carries recurring requirements that should be part of any honest cost analysis.
- Membership renewal: $99 per year, required to keep the credential active.
- Continuing education: 15 CEUs are required annually, with at least half earned through AMBA.
- Current references: as coding sets change, updated resources remain a practical necessity for working coders.
Because at least half of the 15 CEUs must come through AMBA, you cannot rely entirely on free outside sources to satisfy the requirement. The published materials here do not specify per-CEU pricing, so check AMBA's current catalog to estimate your annual education spend. A candidate planning a long career in billing should model the recurring costs the same way they model the initial ones.
Weighing the Fees Against the Job Market
Whether $424 plus ongoing costs is a good investment depends on what the credential does for you professionally. We do not cite specific salary figures here, because there are no verified numbers to publish for this credential. What can be said qualitatively is that the CMRS is aimed at medical billing and reimbursement roles, and the sections it tests reflect the daily tasks of those jobs: coding diagnoses and procedures, preparing CMS 1500 claims, working with clearinghouses, navigating insurance carriers, and keeping claims compliant.
Employers who hire for these functions typically include physician practices, billing companies, and healthcare facilities that need staff who understand the claim lifecycle. For a closer look at the roles and employers, see our overview of CMRS jobs, and for earnings context see the CMRS salary guide. For a structured way to decide whether the investment fits your situation, read whether the CMRS certification is worth it.
Cost FAQ
The exam fee is $325 and the required AMBA individual membership is $99 per year, for a calculated initial total of $424. That figure excludes optional materials such as the $199 regular-price study guide and any current-year coding references you choose to buy.
No. The AMBA study guide is optional and regularly priced at $199. Whether it is worthwhile depends on your existing knowledge of coding, billing, and anatomy. Experienced billers who already own current references may not need it.
Two retakes are included in the exam fee, so you do not pay the $325 again. They are subject to AMBA waiting and completion rules, so confirm timing with AMBA. The passing standard remains 85% cumulative on every attempt.
Yes. You must maintain AMBA membership at $99 per year and earn 15 CEUs annually, with at least half through AMBA. Current-year coding resources are also a practical ongoing expense for working coders.
No separate testing center fee is published. The exam is online and open book, delivered through AMBA's student environment and completed within 45 calendar days of enrollment. No separately verified external testing vendor is listed.
Before you pay, confirm current pricing and requirements directly with AMBA, since fees and outlines can change. When you are ready to test your readiness across the 16 sections, try the practice questions on our main site, and review what is known about the CMRS pass rate to set realistic expectations before you enroll.
