CHONC practice questions - frequently asked questions

Plain answers about how CHONC Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real CHONC exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The CHONC exam spans 14 domains: Medical terminology and anatomy; Medical physiology; Teaching physician guidelines; Incident-to guidelines; Split/Shared services; HIPAA regulations; Proper use of the Advance Beneficiary Notice (ABN); CMS drug wastage policy; Clinical trial services; ICD-10-CM coding; E/M code selection using the AMA CPT E/M guidelines; CPT coding for common procedures; CPT and HCPCS Level II modifier usage; HCPCS Level II coding. Every practice question on this site is tagged to one of these domains.

The CHONC exam has 100 questions and is completed in 4 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
