CBCS Practice Test PDF (Free Printable 2026)

CBCS Practice Test PDF – Study Offline for the NHA Exam

The Certified Billing and Coding Specialist (CBCS) credential is awarded by the National Healthcareer Association (NHA) and verifies that a candidate can accurately translate patient encounters into the standardized codes used for reimbursement, compliance, and reporting across healthcare settings. Passing the CBCS exam demonstrates competency in medical coding systems, revenue cycle principles, insurance billing, and medical terminology — skills that are in steady demand at physician offices, clinics, hospitals, and third-party billing companies.

This page offers a free downloadable PDF that lets you review practice questions away from the screen. Printing the PDF gives you a low-distraction study session: no browser tabs, no notifications, just focused preparation. Work through the questions during a commute, a lunch break, or anywhere you have fifteen spare minutes. Once you have identified the areas that need more attention, return to the full online practice tests on this site for timed, scored sessions that simulate the actual exam environment.

The CBCS exam contains 100 scored questions and must be completed within three hours. The NHA uses a scaled scoring system and sets the passing mark at 390 out of a possible 500 points. Content is drawn from six major knowledge domains: ICD-10-CM diagnosis coding, CPT procedure coding, HCPCS Level II supplies and services, revenue cycle fundamentals, medical terminology, and insurance types. Each domain carries a different weight, but consistent errors in any one area can pull your total score below the passing threshold, so balanced preparation across all six is essential.

What the CBCS Exam Covers

ICD-10-CM Diagnosis Coding

The International Classification of Diseases, Tenth Revision, Clinical Modification underpins diagnosis reporting for every payer in the United States. Each ICD-10-CM code is alphanumeric and can be up to seven characters long. The first character is always a letter; characters two through seven combine numbers and, in some sections, additional letters. Understanding the structure matters because the exam tests your ability to build or recognize codes at the correct level of specificity.

Section guidelines govern how and when certain code blocks are used. Z codes capture encounters and screenings that are not driven by a current illness — for example, Z12.11 for a screening colonoscopy or Z23 for an encounter for immunization. When coding injuries, you will work within the S-code range. The seventh character of an injury code tells the payer whether the visit represents an initial encounter (A), a subsequent encounter (D), or a sequela (S) — the lasting effect of a prior injury. When an injury code requires a seventh character but the code is not seven characters long, a placeholder X fills the intervening positions.

Late effect coding, now referred to as sequela in ICD-10-CM, requires the sequela code first, followed by the code for the originating injury or condition. The exam regularly presents scenarios where selecting the wrong sequencing results in an incorrect answer, so practice with real patient encounters rather than relying solely on code-lookup drills.

CPT Procedure Coding

Current Procedural Terminology, published by the American Medical Association, is the standard for reporting outpatient procedures and professional services. The surgery section is one of the most tested areas on the CBCS. Candidates need to understand the global surgical period concept: major surgeries carry a 90-day global period during which pre-operative and post-operative care are bundled into the procedure fee, while minor procedures carry either a zero-day or ten-day global period.

CPT modifiers refine the meaning of a code without changing its core definition. Modifier -22 signals that the work required was substantially greater than usual and supports documentation of increased procedural services. Modifier -26 identifies the professional component of a service, while modifier -TC identifies the technical component — these two together make up the full value of a diagnostic service. Modifier -51 is used when multiple procedures are performed during the same session. Modifier -59 establishes that two services are distinct from each other and should not be bundled under the National Correct Coding Initiative (NCCI) edits.

Add-on codes, marked in the CPT manual with a plus sign, cannot be reported alone — they are always reported alongside a primary procedure code. Evaluation and Management codes were revised in 2021: the revised guidelines allow physicians to select E/M level based on either total time spent on the encounter date or medical decision-making (MDM) complexity, removing the requirement to count history and examination elements for office visits.

HCPCS Level II Codes

Healthcare Common Procedure Coding System Level II codes are maintained by the Centers for Medicare and Medicaid Services and cover items that CPT does not address — durable medical equipment (DME), orthotics, prosthetics, drugs administered in an outpatient setting, and ambulance transport. DME codes begin with the letter E; drug codes typically begin with J; ambulance transport codes begin with A. Modifiers at the HCPCS Level II level further specify laterality, service setting, or billing circumstances. The exam expects you to recognize code ranges and understand when a HCPCS Level II code is required instead of a CPT code.

Revenue Cycle Fundamentals

The revenue cycle describes every administrative and financial step from patient scheduling through final payment. A clean claim is one that can be processed without additional information — accurate patient demographics, valid insurance information, correct diagnosis and procedure codes, and required attachments all contribute to a clean claim. Each payer sets timely filing limits, typically ranging from 90 days to one year from the date of service, and claims submitted after that deadline are denied without appeal rights.

When a claim is processed, the provider receives an Explanation of Benefits (EOB) from a commercial payer or an Electronic Remittance Advice (ERA) from Medicare and Medicaid. Both documents detail what was billed, what was allowed, what was paid, and what was adjusted. Denial management requires reading adjustment reason codes (ARCs) and claim adjustment reason codes (CARCs) alongside remark codes to understand exactly why a claim was not paid and what action, if any, is appropriate. Accounts receivable management tracks outstanding balances by payer and age bucket; a large proportion of A/R over 90 days typically signals a process problem rather than a collection problem. Superbills, also called encounter forms, are the internal documents providers use to capture diagnoses and services at the point of care before they are translated into formal claims.

Medical Terminology in a Coding Context

Medical terminology on the CBCS is not tested in isolation — it is tested in the context of coding. Understanding anatomical root words (cardi for heart, hepat for liver, nephr for kidney), common prefixes (brady for slow, tachy for fast, hyper for above normal, hypo for below normal), and suffixes (-itis for inflammation, -ectomy for surgical removal, -plasty for surgical repair) allows you to decode unfamiliar diagnoses and procedures without looking them up. This skill becomes particularly valuable under time pressure when you encounter an unusual operative report or a complex diagnostic scenario.

Insurance Types and Billing Rules

Medicare is a federal program covering individuals 65 and older, certain younger individuals with disabilities, and end-stage renal disease patients. When Medicare is the primary payer, claims go to Medicare first; when Medicare is secondary, the primary commercial or employer plan is billed first. An Advance Beneficiary Notice of Noncoverage (ABN) must be issued to Medicare beneficiaries when a provider believes Medicare is unlikely to cover a service — this shifts financial liability to the patient if coverage is denied. Medicaid is a joint federal-state program for low-income individuals; billing rules vary by state. Commercial insurance plans include Preferred Provider Organizations (PPOs), which allow patients to see out-of-network providers at higher cost-sharing, and Health Maintenance Organizations (HMOs), which typically require in-network care and a referral from a primary care physician. TRICARE covers active-duty military members and their families. Workers' compensation billing follows different rules than standard health insurance — the claim is sent to the employer's workers' comp carrier, and the date of injury drives authorization and treatment timelines.

How to Use This PDF for Maximum Benefit

Timed Practice Sessions

Print the PDF and set a timer for the same ratio the actual exam uses — roughly 1.8 minutes per question. Working under time pressure while on paper prepares you for the cognitive load of the real exam, where you cannot pause the clock to look something up. After the timer ends, score your answers honestly and note every question you got wrong or guessed on. Those are your study targets.

Domain-by-Domain Review

The CBCS exam is not equally weighted across all six content areas. If ICD-10-CM and CPT together represent the bulk of the questions, spending most of your preparation time on those two domains gives you the highest return. Use the PDF results to calculate your accuracy by domain, then allocate future study sessions accordingly. A candidate who scores 95% on medical terminology but 55% on CPT modifiers should not spend equal time on both.

Pair with the Online Practice Tests

The downloadable PDF works best as a complement to timed online sessions. The cbcs certification practice tests on this site provide instant scoring, answer explanations, and performance tracking — features that paper cannot replicate. A solid study plan alternates between the offline PDF (for distraction-free review and self-quizzing) and the online tests (for timed simulation and detailed feedback).

Focus on High-Frequency Topics

Certain topics appear repeatedly on billing and coding exams because they represent the competencies most relevant to day-to-day work. Modifier use, coding sequencing rules, global surgical periods, clean claim requirements, and denial reason codes are perennial exam staples. Prioritize these areas during your review, and make sure you can apply the concepts to patient scenarios rather than simply reciting definitions.
