What Score Do You Need to Pass the CPC Exam? (2026 Guide)

The one number that decides everything: 70%

I still remember refreshing the AAPC members area the night after my second part, convinced I'd blown the Radiology questions. I passed, but not by the margin my ego wanted. Here's the thing new coders keep getting wrong about the CPC: there's no curve, no mystery conversion, no committee deciding where the line falls this quarter. AAPC requires an overall score of 70% or higher, which on the current 100-question exam means answering at least 70 questions correctly.

That's it. Seventy of one hundred. The bar doesn't move because your version was harder, and it doesn't move because half the room struggled with the same E/M vignette. If you want the fuller format picture before the scoring details, our breakdown of what the CPC exam is and how it's structured pairs well with this page.

How CPC scoring actually works

Scoring is a straightforward percentage of questions answered correctly, and each question is weighted equally at 1 point. A 10000-series integumentary question is worth exactly as much as a compliance question or an anesthesia formula question. There is no scaled-score conversion published for the CPC. There's no adaptive difficulty adjustment. You get a percentage, and 70% or higher passes.

Two consequences fall out of that, and both should change how you study:

• Nothing is "worth more," so nothing is worth panicking over. Coders love to catastrophize about Anesthesia or Pathology. Each of those questions carries the same 1 point as the ICD-10-CM lookup you can do in your sleep.
• Every skipped question is a guaranteed miss. Equal weighting plus a fixed threshold means a blind guess has positive expected value and a blank has none. Never leave one empty.

The 70% is overall, not per section

This trips people up constantly. The 70% standard is overall — a candidate does not need 70% within each content area. You can have a rough run through Musculoskeletal and still pass comfortably if the rest of your performance carries you. AAPC reports the outcome as a pass or fail against that overall threshold, so your strategy should be to maximize total correct answers across the whole exam, not to defend any single area.

Are some questions unscored?

Candidates ask me this all the time because other certification bodies seed pretest items. For the CPC: AAPC does not publish a pretest/unscored (pilot) question count for the CPC exam, and AAPC does not publish a scored-vs-pretest split for the CPC exam. Treat all 100 questions as counting toward the 70% score unless AAPC states otherwise. Practically speaking, that's the safest assumption anyway — you should be answering every item as though it counts, because it probably does.

The format the score sits on: 100 questions, two parts

The current CPC exam consists of 100 multiple-choice questions and is split into two parts, with a maximum time limit of 2 hours and 45 minutes per part — roughly 5.5 hours total across both. The two parts can be scheduled on the same day at different times, or on different days entirely.

If you're reading older prep material that describes a 150-question exam sat in one marathon block, ignore it. That's the retired format, and the legacy 5 hours 40 minutes figure doesn't apply either. Anything built on the 150-question structure is now a distraction.

The two-part split is genuinely good news for scoring. Fatigue used to eat points late in the old single-sitting format. Now you get a reset between parts, and if you schedule them on separate days you can walk into each one fresh.

Where your points come from: the content areas

The CPC covers medical-coding proficiency across CPT's six code sections, plus diagnosis coding, supply and service coding, terminology, anatomy, and the rules that govern all of it. AAPC lists these areas:

What about how many questions come from each area? Refer to AAPC's official CPC exam content outline for the current per-area question counts. Older per-area breakdowns floating around study groups were built on the retired 150-question format and don't map cleanly onto the current 100-question exam — using them to allocate study time is a good way to over-prepare one area and neglect another.

Open book is part of your score, not a safety net

The CPC is an open-code-book exam, and that shapes the passing threshold more than anything else. You may bring approved code manuals only: one CPT (AMA Standard or Professional edition), one ICD-10-CM, and one HCPCS Level II manual — one of each of the three book types on your desk. Officially published errata update sheets for those manuals are permitted. Nothing else is allowed.

Because the books are there, the exam isn't testing whether you memorized codes. It's testing whether you can find and defend the right one under a clock. Candidates who miss 70% almost never fail from ignorance; they fail from slow lookups. Tabbing, highlighting the guidelines you actually reference, and knowing where the parenthetical instructions live in your CPT is score-bearing work. Our piece on test-day tactics goes deeper on book handling.

A quick anecdote about the clock

The first time I proctored a study group's mock, one student got 90-plus percent on untimed drills and dropped below the line the moment we ran it timed. She wasn't a worse coder that afternoon. She was reading full operative notes top to bottom before glancing at the answer choices. Reading the options first, then hunting the note for the discriminating detail, moved her back above 70% within two weeks. That's a scoring skill, not a coding skill.

Fees, attempts, and what happens if you miss 70%

AAPC lists core exams, including the CPC, at $425 for 1 attempt or $499 for 2 attempts. Student pricing is $400 for 1 attempt and $475 for 2 attempts. An active AAPC membership is required to sit, and membership dues are separate from the exam fee. Because AAPC has revised pricing over the years, confirm the current dollar figure on AAPC's exam-cost page before you check out.

The 2-attempt option bundles a retake with the purchase. AAPC states you get one free retake for the same exam type as long as it's taken within one year of your original exam date, and retakes are scheduled from the members area under My Events > Examinations. A single-attempt purchase does not include a free retake. All exam fees are non-refundable and non-transferable.

My honest take: if you're a career changer who finished a coding program last month and hasn't sat a full-length timed mock yet, the 2-attempt option is cheap insurance. If you're already scoring above the line on realistic timed practice, the single attempt is fine.

Scheduling constraints that quietly affect your score

After buying a voucher you schedule through the AAPC members area, choosing either an online Live Remote Proctored date and time — proctored via external webcam by AAPC's partner Examity — or an in-person approved exam site, including local chapter events. The exam must be taken within one year from the date of purchase. Don't buy the voucher until your study plan has a realistic finish date; our guide to how long CPC prep really takes is a decent reality check.

What about the pass rate?

People want a pass rate so they can decide how scared to be. Here's the straight answer: AAPC does not publish an official CPC pass-rate percentage. The figures you'll see quoted in forums and on prep-company blogs aren't confirmable against an official AAPC source, so I don't build expectations on them and neither should you.

It doesn't matter much anyway. The CPC isn't ranked against other candidates — it's a fixed threshold. Your competition is the 70%, not the person testing next to you.

Eligibility, and the letter after your credential

There's no mandatory education or experience prerequisite to sit the CPC, though AAPC recommends an associate's degree and coding experience. Active AAPC membership is required at the time of exam application and/or when results are released.

Getting from borderline to safely above the line

If timed practice keeps landing you just under, the fix is usually mechanical rather than conceptual:

• Answer every question. Equal weighting means an educated guess costs nothing and can earn a point.
• Triage in passes. Clear the fast lookups first, flag the multi-code operative reports, come back with whatever clock remains in that part.
• Eliminate against the manual, not against your memory. Two of the four options are usually wrong for a reason printed in your CPT guidelines.
• Rehearse the full length. Sitting 2 hours 45 minutes of sustained coding is its own skill, and you want to have done it before it counts.
• Track misses by area, not by count. If Anesthesia keeps costing you points, that's the study session — even though each of those questions is worth the same 1 point as everything else.
