The professional medical-coding certification — adaptive practice for coding guidelines, sequencing judgment, modifiers, and the terminology foundation.
The CPC (Certified Professional Coder, from the AAPC) is the standard credential for physician-practice coders: 100 questions in 4 hours, open-book with your ICD-10-CM, CPT, and HCPCS codebooks, passing at 70%. The exam isn’t memorizing codes — the books are on your desk. It tests whether you can APPLY the system: which official guideline governs, what sequences first, which modifier changes payment, what documentation supports, and where compliance lines (upcoding, unbundling) sit. That applied judgment — plus fast codebook navigation — is the whole game.
Keentune’s medical-coding skill drills the judgment layer: ICD-10-CM structure and its official guidelines (specificity, laterality, combination codes, sequencing, the exclusion notes), E/M leveling concepts, modifier logic, payer and compliance concepts — always at the level of guidelines and reasoning, never reproducing copyrighted CPT descriptor text. The existing medical-terminology and anatomy skills rebuild the substrate every coding decision leans on. Every explanation names the governing rule and the trap. Original questions — never real exam items.
Or take a timed drill — 20 questions, 25 minutes
A focused drill on one section under a real clock — not a full practice exam, and never a predicted CPC (Medical Coding) score.

Practice by section
ICD-10-CM & guidelines
Code structure, specificity and laterality, the official guidelines, sequencing, and the notes that redirect you.
Original practice authored from the public ICD-10-CM code set and official guidelines (US-government works) and general coding knowledge. CPT® codes and descriptors are copyrighted by the AMA and are not reproduced here — the exam requires the official codebooks, which this practice complements rather than replaces. Keentune is independent study practice, not affiliated with or endorsed by the AAPC, AHIMA, or the AMA, and never guarantees a pass.
Yes — you bring your own ICD-10-CM, CPT, and HCPCS books (tabbed and annotated within AAPC’s rules). That’s why memorizing codes is the wrong prep: the exam pays for guideline mastery and NAVIGATION speed. Practice finding-and-applying, and know the official guidelines nearly by heart.
What is a CPC-A?
The apprentice designation you hold after passing but before meeting AAPC’s experience requirement (generally two years, reducible through their practicum). Most new coders start as CPC-A — employers know it and hire for it, especially in billing-adjacent roles.
Why doesn’t this practice show CPT codes?
CPT is copyrighted by the AMA — reproducing its codes and descriptors requires a license, and honest prep respects that. The concepts the exam tests (guidelines, sequencing, modifiers, E/M logic) are fully drillable without the protected text, and ICD-10-CM — which is a US-government work — is used directly.
