Don’t worry, you’re not alone. Hundreds of students have used our CCO Proven Process and COC Practice Exams to help prepare and pass the AAPC’s COC® Exam.

Why Is Our COC Practice Exam So Effective?

Unlike other Inpatient coding practice exams in the marketplace, all our instructors are CPC® Certified and many have sat through the original AAPC COC® Exam. We learned the material in detail and have been working with students for years to help teach them Outpatient Medical Coding. Now we’ve assembled our knowledge into these COC® Practice Exams to help prepare for the official exam. Here are a few things you can expect from our tests.

Inspired by the AAPC COC® Exam

Many CCO Instructors have previously sat and passed the AAPC COC® Exam. With our combined experience, we have first hand knowledge of what you need to know for Inpatient coding. These practice tests mimic the experience as closely as possible.

Real World Examples

We’ve gone through a lot of trouble to verify our COC Practice Exams are accurate and correctly coded. We have each question reviewed by Certified instructors before they’re approved. And most of these cases can be seen in the real world.

Answer Rationale Included

You know what’s frustrating? Getting a COC® exam answer wrong and not knowing why. That’s why CCO has included full rationale explanations with every COC® question in our practice exams. So don’t worry, if you get any questions wrong, you’ll know why.

How to Pick the Best COC Practice Exam?

The COC™ (formerly CPC-H®) examination consists of questions regarding the correct application of CPT®, HCPCS Level II procedure and supply codes and ICD-10-CM diagnosis codes used for coding and billing outpatient facility/hospital and freestanding ASC services to insurance companies.

The best COC® practice exams should be able to fully prepare its examinee for the real medical outpatient exam. It’s critical that important topics and questions are clearly laid out so examinees are not surprised on the day of the exam.

The AAPC COC® exam is 150 multiple-choice questions and must be completed in 5 hours and 40 minutes or less.
