Free CPC Practice Questions (2026) — 10 Sample Q&As Explained

The Certified Professional Coder (CPC) exam from AAPC is a 100-question multiple-choice test administered over 240 minutes — four hours — with a minimum passing score of 70%. Registration costs $425 for a single attempt, so every point of preparation protects a real financial stake. The 10 practice questions below come with fully worked explanations, and they deliberately mix two skills the exam rewards: reasoning through coding principles, and doing the quick arithmetic that turns the exam's published numbers into a pacing, scoring, and budgeting plan.

How to use these questions

Work each item before reading the explanation, and pay as much attention to why the wrong answers are wrong as to the correct choice. CPC distractors are rarely random — they are built from plausible-sounding shortcuts (alphabetical order, higher reimbursement, round numbers) that fail under the actual rules. Training yourself to name the flaw in each distractor is one of the fastest ways to raise your score.

10 CPC practice questions, fully explained

1. What determines the first-listed diagnosis?

A coder must decide the sequencing of codes for an encounter. Which consideration most directly determines which diagnosis is listed first?

  1. The alphabetical order of the diagnosis descriptions
  2. The condition chiefly responsible for the encounter as supported by documentation
  3. The diagnosis with the longest code
  4. The diagnosis that reimburses the most

Correct answer: B. Sequencing is driven by the condition chiefly responsible for the encounter, as supported by the documentation — not by any mechanical or financial shortcut. Option A fails because alphabetical order is a lookup convenience, not a sequencing rule. Option C confuses code length with clinical significance; they have no relationship. Option D is the most dangerous distractor: choosing codes to maximize reimbursement rather than to reflect the documented encounter is not just wrong on the exam, it describes improper coding practice. When a sequencing question appears, ask one question first: what was this patient actually seen for?

2. How much time do you have per question?

A study-skills advisor helps a client plan pacing to reduce test anxiety. Given the total number of items and the total time, roughly how much time is available per question on average?

  1. About 1.4 minutes per question
  2. About 2.4 minutes per question
  3. About 4 minutes per question
  4. About 6 minutes per question

Correct answer: B. Divide the 240-minute time limit by 100 questions: 240 ÷ 100 = 2.4 minutes per question on average. This number isn't published anywhere as a standalone figure — it's a calculation you should do yourself and internalize before exam day. In practice, straightforward recall items should take well under 2.4 minutes so you can bank time for case-based questions that require flipping through your code books. Options C and D would imply exams of 400 and 600 minutes respectively, and option A shortchanges you by a full minute per question.

3. What does one attempt cost?

When registering a wellness-program employee for their first CPC certification attempt, what is the published fee for a single attempt?

  1. $325
  2. $399
  3. $425
  4. $525

Correct answer: C. The published CPC exam fee is $425 for one attempt. The distractors are typical of fee questions: plausible round-ish numbers near the true figure. There is no derivation here — this is a fact you either know or look up, which is exactly why it's worth memorizing the handful of published exam logistics (100 questions, 240 minutes, 70% to pass, $425 per attempt) as a single cluster.

4. Budgeting for a first attempt plus one retake

A candidate fell just short of passing and plans to retake the exam. If the same fee applies to each attempt, what is the total amount the candidate will have paid across the first attempt and one retake?

  1. $650
  2. $750
  3. $850
  4. $950

Correct answer: C. Each attempt costs $425, so two attempts total $425 × 2 = $850. The arithmetic is trivial, but the question models a useful habit: chaining a known fact through a simple operation instead of guessing. If you picked A or B, you likely anchored on a lower remembered fee — which is why locking in the exact $425 figure matters before you start deriving from it.

5. How many questions can you afford to miss?

A test-taker asks how many questions they can miss and still pass, in order to manage catastrophic thinking. Using the item count and passing threshold, approximately how many questions must be answered correctly?

  1. About 50 questions
  2. About 60 questions
  3. About 70 questions
  4. About 90 questions

Correct answer: C. With 100 questions and a 70% passing threshold, 70% of 100 is roughly 70 correct answers. Flip that around and the anxiety-management payoff appears: you can miss on the order of 30 questions and still pass. No single hard question can sink you. Option D (about 90) reflects the perfectionist framing this question is designed to dismantle; options A and B would correspond to passing thresholds the exam doesn't use.

6. The exact minimum number of correct answers

A candidate has answered every item and wants to know the minimum number of questions they must get correct to clear the passing threshold. Based on the passing score and total question count, how many questions must be answered correctly at minimum?

  1. 60 questions
  2. 65 questions
  3. 70 questions
  4. 75 questions

Correct answer: C. The passing score is 70% and the exam has 100 questions, so 70% of 100 equals exactly 70 correct answers. Because the exam happens to have 100 items, the percentage threshold and the raw-score threshold are the same number — a convenient property worth noticing, since it means every practice-test question you get right maps one-to-one onto a percentage point.

7. Reading your margin above the threshold

A candidate answered 72 of the 100 questions correctly on the actual exam. Relative to the minimum required to pass, how many correct answers did they have to spare?

  1. 0 to spare — they exactly met the threshold
  2. 2 to spare
  3. 5 to spare
  4. They fell 2 short

Correct answer: B. The minimum to pass is 70% of 100 questions, which is 70 correct. Answering 72 correctly leaves 72 − 70 = 2 correct answers to spare. Option D inverts the comparison — a common slip when working quickly — and option A confuses "near the threshold" with "at the threshold." When a question asks for a margin, write down both numbers (score and threshold) before subtracting; it prevents exactly the sign error option D represents.

8. Interpreting a 68% practice-exam score

A candidate scored exactly 68% on a full-length CPC practice exam. Compared with the official minimum passing score, what is the candidate's status?

  1. Above the passing threshold by 2 percentage points
  2. Exactly at the passing threshold
  3. Below the passing threshold by 2 percentage points
  4. Below the passing threshold by 7 percentage points

Correct answer: C. The passing score is 70%, and 70 − 68 = 2, so a 68% practice score sits 2 percentage points below the threshold. The practical reading matters more than the arithmetic: on a 100-question test, 2 percentage points is just 2 additional correct answers. A candidate at 68% is not far from ready — they need targeted review of their weakest content areas, not a restart from scratch.

9. Setting aside funds for two attempts

A candidate must budget for a single CPC exam attempt and knows the per-attempt fee. If they set aside funds for two separate attempts at the published single-attempt fee, what total amount should they budget?

  1. $725
  2. $800
  3. $850
  4. $950

Correct answer: C. The published fee is $425 per attempt, so two attempts cost $425 × 2 = $850. This mirrors question 4 by design: the same fact ($425) supports multiple question framings — retake cost, contingency budgeting — and the exam frequently re-tests one underlying figure from different angles. If you recognized the repetition immediately, that's the fluency the practice is building.

10. Reframing the exam's length

When counseling a client who feels overwhelmed by preparation, a coach reframes the exam's length as manageable. Based on the published time allotment, how long is the exam?

  1. 120 minutes
  2. 180 minutes
  3. 240 minutes
  4. 300 minutes

Correct answer: C. The published duration is 240 minutes — four hours. None of the other durations is supported by the source. The reframe the question gestures at is real: four hours sounds daunting in the abstract, but paired with the per-question math from question 2, it works out to a comfortable 2.4 minutes per item on average, which is generous for well-prepared candidates on recall questions.

Putting the numbers together

Three derived figures from these questions are worth writing on a sticky note during your prep: you have about 2.4 minutes per question, you need at least 70 of the 100 questions correct to clear the 70% threshold, and each attempt costs $425 — so passing the first time is worth a concrete $425 to you. Practice questions in isolation build knowledge; full-length timed practice builds the pacing and stamina the four-hour format demands. When you're ready to simulate the real thing, take a full free CPC practice test and score yourself against the 70-correct benchmark from question 6.
