AAPC Certified Professional Coder (CPC) Examination Practice Test
The CPC examination assesses medical coding skills used to translate clinical documentation into accurate diagnosis and procedure codes. The work requires interpreting provider notes, identifying documented conditions and services, and applying code-set conventions to outpatient claims. Practice in this area draws on clinical terminology, anatomy, and the structure of ICD-10-CM, CPT, and HCPCS Level II codes.
Exam overview
About the AAPC Certified Professional Coder (CPC) Examination Exam
A coder must distinguish a documented diagnosis from symptoms, identify the service actually performed, and select codes supported by the record. This involves reading operative and evaluation-and-management documentation, locating terms in code references, and confirming choices in the relevant tabular instructions. Coders also apply conventions such as laterality, code sequencing, bundling edits, modifiers, and documentation requirements where applicable. Medical terminology and anatomy help connect clinical descriptions to the correct code category, while knowledge of claim rules supports accurate reporting. The central judgment is whether the documentation and coding instructions justify a particular code, modifier, or sequence; unsupported detail should not be added to a claim. These skills support consistent coding, defensible claim submission, and clear communication when documentation needs clarification.
How to use this practice test
US Practice Tests access is free. When practice questions are available, a session draws up to 20 random questions from the CPC practice bank and displays results after completion. Use the results to identify coding decisions that need more work, then revisit the relevant code references and documentation concepts before another session.
Preparation tips
- Practice moving from a clinical term in the Alphabetic Index to the Tabular List, and verify all instructional notes before finalizing a code.
- For each case, separate documented diagnoses, symptoms, and services; do not code conditions or details that the record does not support.
- Review CPT modifier use and bundling concepts by checking how the documented service and circumstances affect code reporting.
- Strengthen anatomy and medical terminology so you can distinguish similar structures, conditions, and procedure descriptions in clinical notes.
- When reviewing an incorrect answer, identify whether the issue was documentation interpretation, code lookup, sequencing, or an overlooked convention.
