CPC Pass Rate: What AAPC Publishes and What 70% Means

We could not verify a current overall or first-time CPC pass rate in the public AAPC sources we checked. For its Certified Professional Coder (CPC) exam, AAPC confirms that 70% is the score you need (at least 70 of 100 questions correct); its student-outcome claims describe different groups (AAPC passing-score answer).

CPC pass-rate claims, decoded

Here are the figures we found, who published them, and what they actually count.

CPC pass-rate claims: source, population, and limits
Number you'll see Who says it What it actually measures Can you check it? How to use it
70% AAPC The passing score: at least 70 of the 100 questions correct. AAPC itself calls this a "passing rate of 70 percent," which is why it gets mistaken for a pass rate. Yes — AAPC passing-score answer Your target. It says nothing about how many people pass.
More than 80% for AAPC's CPC students AAPC Help Center, July 21, 2023 AAPC's own CPC students. No cohort dates, head count, or first-attempt definition. The statement, yes — AAPC graduate-outcomes answer. No underlying dataset is supplied. A dated student-cohort claim, not a verified national or first-attempt CPC rate.
80% of AAPC students pass on the first attempt (also: "three times more likely to pass") AAPC, in its May 23, 2024 help-center article on Certified Professional Biller (CPB) An AAPC student claim in a CPB article; no CPC-specific cohort, cohort year, head count, or comparison baseline is identified. The statement, yes — AAPC CPB article, "Pricing". The data behind it, no. A training provider's claim about its customers. Not a CPC-wide rate.
36% to 60%, 2016–2019 AAPC case study on a University of Florida employee program One employer training program, by year. No head counts or first-attempt definition. Yes — AAPC case study, p. 4 A dated program result. See the table below.
"2.2× the national average" Same case study, describing UF's 2019 result A comparison against a "national average" the document never defines or gives a source for. The statement, yes. The national figure, no. Don't back-calculate a national rate from it.
54% first-time, labeled an AAPC-reported average PracticeTestGeeks Unknown cohort. No supporting AAPC pass-rate dataset is linked. The page also gives a 5-hour-40-minute duration; AAPC's current exam is 100 questions in 4 hours. The claim, yes — PracticeTestGeeks, "CPC Certification by the Numbers". The supporting dataset, no. Do not use as a verified national rate.
50–60% first time, 70–80% eventually, 35–50% self-study OpenExamPrep, labeled "estimates" Estimates attributed to training-program reports, forum posts and surveys. The underlying data isn't identified. The claims, yes — OpenExamPrep, "Estimated CPC Pass Rates". The supporting datasets, no. Unverified; do not use as national rates.
About 90% first-time "reported by AAPC" Medesun's course page The underlying national cohort and report are not identified. The claim, yes — Medesun, training-versus-self-study section. No supporting AAPC pass-rate report is linked with it. Do not use as a verified national rate.

Check the group behind the number. Figures credited to AAPC run from about 54% to about 90%, depending on who's quoting. Those figures cannot be compared without matching their populations, periods and counting rules. None of the figures we verified establishes a current national CPC pass rate.

AAPC's dated Help Center graduate-outcomes answer includes the more-than-80% claim; its main-site answer with the same title gives no percentage. Neither supplies the missing cohort details.

A passing score and a pass rate answer different questions

A score describes one person: how many questions you got right. A pass rate describes a group: how many people in it passed. A pass rate means nothing until you know who's in the group and how they were counted.

Because the CPC standard is a fixed 70 correct answers out of 100, your result doesn't depend on anyone else. Whether most candidates pass or most fail, you still need at least 70. AAPC states the rule as 70 of the 100 questions overall and doesn't describe a separate minimum for each section (AAPC).

In practice, that means:

  • You can miss up to 30 questions and still pass.
  • Four hours for 100 questions averages 2.4 minutes per question (AAPC exam format). That's an average, not a rule — individual questions can take different amounts of time.

Why one group can have four different "pass rates"

This is an invented example, not CPC data. It shows why different counting rules can produce different rates for the same group.

Twenty people take an exam once. Twelve pass. Over the next six months, all eight who failed take it one more time, and six of them pass. Nobody drops out and nobody takes a third attempt.

Four example pass rates from one invented group
Rate Calculation Result
First-attempt pass rate 12 first-try passes ÷ 20 people 60%
Retake pass rate 6 second-try passes ÷ 8 retakers 75%
Eventual pass rate (within six months) 18 people who passed ÷ 20 people 90%
Pass rate per attempt 18 passing attempts ÷ 28 total attempts about 64.3%

All four are correct. They just answer different questions. The 90% is not a first-try rate, and the per-attempt figure counts the eight retakers twice. When a page quotes "the" CPC pass rate without saying which of these it means, you can't tell what you're looking at.

What AAPC's historical program data shows

The one set of year-by-year CPC pass rates we found in an AAPC publication comes from a case study about a training program AAPC ran with the University of Florida for UF and UF Health employees (AAPC case study, pp. 2 and 4).

AAPC historical program cohort data, 2016 to 2019
Year Program pass rate shown in AAPC's chart
2016 36%
2017 58%
2018 45%
2019 60%

The document doesn't give how many people tested each year or whether these are first attempts. They describe one employer's program from 2016 to 2019, not today's candidates nationally.

One more detail worth noticing: the case study headlines a "24% increase" in pass rates. The chart goes from 36% to 60%. That's a rise of 24 percentage points — or about 67% in relative terms (24 ÷ 36). Same data, very different-sounding claims. It's a good reminder to ask what a percentage change is measured against.

How to check any CPC pass-rate claim

Run any number you find through these five questions.

  1. Which exam and which people? CPC specifically? All candidates, one school's students, course finishers, or people who answered a survey?
  2. Which years? A page updated this year can still quote results from years ago, under an older exam format.
  3. Who's in the denominator? Everyone who enrolled, only those who finished, only those who sat the exam — and how many?
  4. Which attempt? First try, retakes, or eventual success? For "eventual," over how long, and what happened to people who never came back?
  5. Can you see the source? A named report with definitions beats a "data shows" claim. "Three times more likely" or "2.2× the average" also needs a baseline you can see.

If a claim can't answer these, it doesn't tell you a national CPC pass rate, and it doesn't tell you your odds. A training provider's report can be accurate about its own students without describing anyone else. And ten websites repeating the same unsourced figure is still one unsourced figure.

One attempt or two? The break-even math

A pass-rate statistic cannot tell you whether you will use a second attempt. If you're comparing vouchers, AAPC sells one- or two-attempt options (AAPC); the prices below are those listed on its dedicated CPC exam-cost page.

Price difference between sources: AAPC's CPC Help Center article lists a $399 single-attempt price. The table uses the dedicated cost-page prices; confirm your checkout quote before relying on the calculation.

One attempt or two: voucher break-even math
Exam-voucher cost Standard price Student price
One attempt $425 $400
Two attempts $499 $475
Extra cost of the second attempt $74 $75
Two single vouchers if you take a second attempt $850 $800
Saved by the two-attempt voucher if you use the retake $351 $325
Break-even chance of using a second attempt 74 ÷ 425 ≈ 17.4% 75 ÷ 400 = 18.75%

How to read it: under these assumptions, the two-attempt voucher has the lower expected exam-voucher cost if the chance of actually using a second attempt exceeds about 17.4% at standard prices or 18.75% at student prices. Below the relevant threshold, buying one attempt first has the lower expected cost. This calculation does not estimate your chance of passing.

If that chance is written as p, the single-attempt-first cost is $425 + $425p at standard prices or $400 + $400p at student prices. Compare it with the fixed two-attempt price. A practice score does not supply p.

This is our arithmetic. It assumes a later single attempt costs the price used in the table, that you would use an included second attempt within its applicable validity, and that you have no other retake entitlement. It leaves out membership, promotions, any third attempt and other costs. Before you buy, know that:

  • Check your voucher's actual deadline. AAPC's general voucher answer says one year from purchase, while its CPC Help Center article describes another year after the first attempt for an included second attempt. Its retake guidance directs candidates to the original purchase terms. Confirm the deadline that applies to your voucher with AAPC if the terms or account display are unclear.
  • If you do not pass your first attempt, an included second attempt becomes available after your first attempt's results release — you can't schedule both attempts together (AAPC).
  • If you pass first time, the unused second attempt can't be moved to another exam (AAPC).

Booking steps: AAPC's scheduling instructions.

What to do with this

Use your own work to find what needs review. Don't let an unsourced percentage tell you that you'll pass or fail.

If you're preparing for your first attempt

  • Practice under exam conditions. Fresh questions, the references permitted for your exam, a clock running against the 2.4-minute average.
  • Log why you missed each one. A coding rule, a detail in the note you skipped, a slow lookup, or time. Each has a different fix.
  • Retest the rule on a new example. Getting the same question right twice can reflect memory. A new example helps you check whether you can apply the rule.
  • Don't read a practice score as a forecast. We have not validated our practice set against AAPC exam outcomes. A practice percentage describes those questions.

If you've just had an unsuccessful result

Open your exam details in your AAPC account (MyAAPC > Exams). AAPC lists Areas of Study there (AAPC). Use them to pick what to revisit first. Then check what your purchase actually covers — an included second attempt becomes available after an unsuccessful result releases. A one-attempt voucher does not include a retake; check for another existing entitlement before buying another (AAPC retake guidance).

Quick answers

Is the CPC exam graded on a curve? No curve is described in AAPC's published passing-score answer. Its rule is at least 70 of 100 correct.

How soon will I know my result? AAPC says most results post to your AAPC account within 7–10 business days, and it doesn't give results by phone (AAPC).

If I pass, am I a CPC? Passing candidates who have not met AAPC's experience or approved-equivalency requirements receive CPC-A, the apprentice designation. Two years of documented coding work is one route; qualifying coding education and successful Practicode completion can also count (AAPC pathways). Project Xtern contributes the actual time spent at the facility — it does not automatically grant a year for a shorter placement (AAPC). More in CPC exam requirements.

Do other coding certifiers publish pass rates? Some do, each with its own definition — first-time testers for one, all exams given for another (AHIMA · NHA). Our medical billing and coding certification comparison lays them out with their denominators.

Sources and verification

Last verified: October 21, 2026. We checked AAPC's published passing requirement, exam format, student-outcome claims, voucher options, prices and validity, retake scheduling, results timing, Areas of Study and apprentice requirements on its support pages and help center. We also read AAPC's University of Florida case study and the named third-party pages behind the numbers in the first table. We did not verify a current national overall or first-time CPC pass rate in the public sources reviewed. The price and voucher-timeline differences between official pages are identified above. This is a review of what those sources publish. We didn't audit candidate outcomes, and this page hasn't been reviewed by a certified coder or by AAPC.
