COC exam key facts

  • The COC exam has 100 multiple-choice questions and is open book, allowing approved CPT, ICD-10-CM and HCPCS Level II code books. Source
  • Candidates have four hours in one sitting to complete the COC exam, about 2.4 minutes per question. Source
  • Passing the COC exam requires an overall score of 70%, which means at least 70 of the 100 questions answered correctly. Source
  • The AAPC Certified Outpatient Coder (COC) exam costs $425 for a one-attempt exam voucher. Source
  • COC candidates can buy a two-attempt voucher to cover a retake, and anyone who fails is told which areas they scored 65% or less on to help them prepare for retesting. Source
  • An AAPC COC exam voucher is non-refundable and must be used within one year of the purchase date. Source

What Practice Test Geeks adds beyond an AI chat for COC

An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:

  • A timed, full-length COC mock exam — 100 questions in 240 minutes with a 70% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
  • A fixed COC question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
  • Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
  • A printable COC cheat sheet you can print or save as a PDF.
  • Free COC practice tests with the correct answer shown after each question.
