Taking the CPC® exam

Who should take the CPC exam?

To ensure you're prepared to pass the exam the first time, we recommend taking the CPC Training Course beforehand.

If you've completed the training course and have a solid understanding of medical terminology, anatomy, and pathophysiology, take advantage of the opportunity to showcase your expertise with the CPC certification. Earning this credential can boost your earning potential and set you apart from uncertified candidates.

What to expect on exam day

The exam has a total of 100 questions to be answered in four hours. People often wonder if the CPC exam is hard. We'll say this: If you have taken the training course, studied, and are familiar with your CPT^®, ICD-10-CM, and HCPCS Level II code books, the test will be demanding, but not difficult.

Here's a quick overview of what you can expect:

Before you begin the test, take a moment and breathe. You have prepared for this. You have your code books by your side and know how to use them. This is your opportunity to demonstrate your coding expertise.

You'll have four hours to finish the exam, giving you approximately 2.4 minutes to answer each of the 100 multiple-choice questions. You can save time by reading the answer choices before reading each question and by saving the more difficult questions for last. It’s important to answer every question, even if you aren’t sure. Your best guess is better than no answer at all.

The questions assess 17 areas of knowledge, most of which are presented as coding scenarios to test application of CPT^® procedure codes, HCPCS Level II procedure and supply codes, and ICD-10-CM diagnosis codes. The end of the exam has 10 cases that test the ability to read and accurately code a medical record.

You will be able to reference approved medical code books during the exam — the AMA's CPT^® Professional Edition, as well as your choice of ICD-10-CM and HCPCS Level II code books. To be clear, these are the only code books you are allowed to use.

Passing grades

An overall score of 70% or higher is required to pass the certification exam. For a passing score of 70%, you must get at least 70 questions correct. If you incorrectly answer more than 30 questions, you will not pass. If you don’t pass, you will be notified of the categories/areas of study with sub-scores of 65% or less to help you prepare for retesting.

All AAPC certification exams exclusively measure proficiencies relating to the one credential named in the exam. To earn additional medical coding credentials, you will be required to pass additional certification exams.

Your results will be shared with you online in your My AAPC Account Dashboard under My Exams. You can expect the results within 7-10 business days after taking the exam. Once you have passed, your certificate will be sent to you in the mail.
