About CPC Prep: Free CPC Medical Coding Exam Practice

CPC Prep is an independent site. CPC Prep publishes free CPC (Certified Professional Coder) exam-prep resources: practice quizzes and plain-language study guides built from AAPC's published CPC exam content outline.

What this site is

The CPC exam tests ICD-10-CM, CPT, and HCPCS Level II coding across roughly 100 questions in a fixed time limit, and the domains are weighted unevenly. Our practice sets mirror that weighting rather than treating every coding area as equally likely to appear, and each question links back to the code set section it draws from.

How we work

We build from AAPC's published CPC exam content outline and the current-year ICD-10-CM, CPT, and HCPCS code books. Content is drafted with AI assistance and then checked against those code books before publishing; see our editorial policy for the review steps. When the annual code set update changes a code or guideline, we update the affected questions rather than leaving them stale.

How we make money

Practice questions cost nothing here. We earn affiliate commissions on code books, study guides, and prep courses purchased through links on this site, detailed in our disclosure.

Corrections

Codes and guidelines change every year. If something's out of date, tell us through contact and we'll fix it with a date noted.
