Taking the CPC^® exam

The CPC exam is a test of medical coding proficiency consisting of 100 multiple-choice questions that assess 17 areas of knowledge. Most questions present a coding scenario to test proper application of CPT^® procedure codes, HCPCS Level II procedure and supply codes, and ICD-10-CM diagnosis codes. Medical providers use all of these to submit claims to payers.

You must complete the CPC exam within four hours and answer 70% of the questions correctly to pass.

Who should take the CPC exam?

After you’ve trained with AAPC to become a medical coder — or if you have substantial medical coding experience — you should take the opportunity to gain certification by registering for the CPC exam.

Passing the CPC exam can elevate your earning potential by more than $25,000 above annual salaries for persons without AAPC's medical coding certification.

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.
