Medical Coding Mock Exams

Analogy — Studying coding rules without taking timed mock exams is like practicing free throws alone in an empty gym and then expecting to sink them in a packed arena with a clock running. The skill you built in isolation (knowing a rule) isn't the same skill the real moment demands (recalling and applying it correctly, under time pressure, on a case you haven't seen before). Mock exams are the "practice under game conditions" step most self-study skips.

Purpose

Timed mock examinations for ICD-10-CM, CPT, HCPCS, and medical coding certification preparation. Designed to replicate the actual exam environment for CPC, COC, CCA, CCS, RHIT, and BCHHC credentials.

Exams Covered

CPC

AAPC -- 100 MCQ, 4 hrs, 70% to pass. Outpatient/physician coding

CCS

AHIMA -- 107 items (97 scored), 4 hrs. Inpatient + outpatient

CCA

AHIMA -- coding fundamentals, verify current format

BCHHC

Certifying body unclear (BMSCC/AHCC/WellSky) -- verify directly. Home health coding

Certification	Body	Format	Focus

|-------------|------|--------|-------|

CPC	AAPC	100 MCQ, 4 hrs, 70% to pass	Outpatient/physician coding
COC (formerly CPC-H)	AAPC	MCQ format, verify current question count/time	Hospital outpatient coding
CCA	AHIMA	MCQ, verify current format	Coding fundamentals
CCS	AHIMA	107 items (97 scored), 4 hrs, passing score 300 — verify current format	Inpatient + outpatient — see this course's dedicated CCS technology for ICD-10-PCS, root operations, and inpatient sequencing
RHIT	AHIMA	MCQ, verify current format	Health information management
BCHHC	Certifying body unclear — sources vary between BMSCC/AHCC/WellSky, verify directly	MCQ, case-based	Home health coding

Note: COC was formerly named CPC-H — if you see "CPC-H" in older study material, it refers to the same credential under its current name, COC.

Mock Exam Strategy

•Time yourself strictly — exam conditions build the right habit

•Review every wrong answer with the ICD-10-CM/CPT guideline that applies

•Track weak topic areas and focus study sessions there

•Repeat the same mock exam after 2 weeks to measure improvement

•Final week: 1 full timed mock per day

Key Coding Guidelines to Master Before Mock Exams

1.ICD-10-CM Official Guidelines (especially Sections I, II, III, IV)

2.UHDDS definitions for inpatient setting

3.CPT Surgery/Medicine/E&M guidelines

4.HCPCS Level II coding manual

5.Coding Clinic and CPT Assistant guidance

Who This Is For

Medical coding students preparing for their first certification, working coders recertifying, and healthcare professionals adding coding credentials.

Full Timed Mocks

Under conditions matching your target exam's real format

1.Complete the coding-specific technology modules first (CPT, HCPCS, ICD-10-CM, Coding Guidelines, CCS, or Home Health Coding/BCHHC Prep depending on your target credential)

2.Use this section's Fundamentals for exam-taking mechanics and timed-practice strategy

3.Use Certification Guide for exam format and study-resource specifics per credential

4.Run full-length timed mocks under conditions matching your target exam's real format

Using the Exams Covered table above:

1.If your target credential is CPC, how many questions and how much time does the table say to expect?

2.Which of the listed credentials has its certifying body flagged as unclear/needing direct verification, rather than stated as a confirmed fact?

3.Why does that distinction (stated fact vs. flagged-for-verification) matter before you register for an actual exam?

You should land on: CPC = 100 MCQ, 4 hours; BCHHC is the one flagged as unclear (sources vary between BMSCC/AHCC/WellSky); and the distinction matters because registering for the wrong exam body, or preparing against an outdated format, wastes real time and money — flagged items are exactly the ones worth a 10-minute direct check before committing.
