What Is the NHA CBCS Certification?
The CBCS is an entry-level certification offered by the National Healthcareer Association that validates competency in both medical billing and foundational coding tasks. Unlike credentials that focus only on code assignment, the CBCS covers the full revenue cycle — from verifying patient insurance at the front desk to submitting claims, posting payments, and managing denials.
According to NHA's 2025 Industry Outlook, 94% of employers require or encourage certification for medical billing and coding specialists. The CBCS credential is NCCA-accredited, meaning it meets nationally recognized standards for personnel certification programs. NHA was founded in 1989, is headquartered in Leawood, Kansas, and has supported more than 1.25 million allied health certifications.
Certified billing and coding specialists work in physician offices, hospitals, surgery centers, nursing homes, home healthcare agencies, mental health facilities, dental offices, insurance companies, and third-party billing firms. For a full comparison of NHA certification paths, see the MedicoExam NHA certification hub.
Who Is Eligible to Take the CBCS Exam?
Candidates must meet one of two eligibility pathways to sit for the CBCS exam. Both pathways require a high school diploma or GED, or scheduled completion of high school/GED equivalency within the allowed NHA window.
Pathway 1 — Education Route:
- Possess a high school diploma or GED, or be scheduled to earn one within 12 months.
- Complete a medical billing and coding training or education program within the last 5 years.
Pathway 2 — Experience Route:
- Possess a high school diploma or GED.
- Complete 1 year of supervised work experience in medical billing and coding within the last 3 years, or 2 years of supervised work experience within the last 5 years.
No associate degree or bachelor's degree is required. This makes the CBCS one of the fastest entry points into the healthcare revenue cycle field. High school health science students may also qualify through NHA's provisional certification pathway; always verify eligibility details in the current NHA Candidate Handbook before registering.
What Are the Four CBCS Exam Domains?
The current public NHA CBCS test plan organizes the 100 scored exam items into four domains. These domains mirror core billing and coding responsibilities in entry-level healthcare revenue cycle roles.
| Domain | Scored Items | Percentage of Scored Exam |
|---|---|---|
| The Revenue Cycle and Regulatory Compliance | 15 | 15% |
| Insurance Eligibility and Other Payer Requirements | 20 | 20% |
| Coding and Coding Guidelines | 32 | 32% |
| Billing and Reimbursement | 33 | 33% |
| Total | 100 | 100% |
Note: The exam also includes 25 pretest items. Pretest questions are not scored, but they are mixed into the exam and cannot be identified during testing.
Domain 1: The Revenue Cycle and Regulatory Compliance (15%)
This domain tests your understanding of revenue cycle workflow and the legal framework that governs billing and coding. Key competencies include:
- Revenue cycle phases and how each phase affects reimbursement.
- HIPAA privacy and security rules for protected health information (PHI).
- HITECH Act requirements for electronic health information.
- Fraud and abuse prevention, including the False Claims Act, Stark Law, and OIG compliance principles.
- Proper release of PHI according to law, payer requirements, and facility policy.
- Documentation, audit requirements, compliance plans, and internal controls.
- Communication with patients, providers, payers, and internal revenue cycle teams.
Domain 2: Insurance Eligibility and Other Payer Requirements (20%)
This domain focuses on front-end payer rules and patient financial responsibility. Key competencies include:
- Verifying insurance eligibility, benefits, copayments, deductibles, coinsurance, and out-of-pocket limits.
- Collecting insurance cards, identification, referrals, authorizations, and assignment-of-benefits documentation.
- Understanding primary, secondary, and tertiary payer order.
- Applying coordination of benefits rules, including dependent and birthday-rule scenarios.
- Distinguishing commercial plans, Medicare, Medicaid, Medigap, TRICARE, workers' compensation, and other payer types.
- Recognizing preauthorization, precertification, predetermination, referral, and medical necessity requirements.
- Handling uninsured or self-pay patient policies and Advance Beneficiary Notice (ABN) concepts.
Domain 3: Coding and Coding Guidelines (32%)
This is the largest coding-focused domain on the exam. Candidates are expected to understand how codes are selected, sequenced, and supported by documentation. Key competencies include:
- Abstracting required health information from clinical documentation.
- Applying ICD-10-CM diagnosis codes to the highest level of specificity.
- Applying CPT and HCPCS Level II codes based on provider documentation.

Expert Insight: "The CBCS exam rewards candidates who understand the full revenue cycle, not just isolated coding terms. You need to know how patient intake, payer rules, documentation, code selection, clean claims, payment posting, and denials all connect." — MedicoExam Content Team
How Does the CBCS Reference Material Policy Work in 2026?
The CBCS exam is no longer a manual-based open-book exam. NHA's 2024 CBCS FAQ states that coding manuals were required only through September 23, 2024. As of September 24, 2024, coding manuals are not necessary or allowed in the exam room. NHA explains that all necessary information for application-of-coding items is included alongside each question.
This change means candidates should shift their preparation strategy. Instead of practicing only manual lookup speed, focus on:
- Understanding coding conventions and guidelines.
- Reading clinical documentation carefully.
- Recognizing correct code sequencing logic.
- Applying modifiers and payer requirements.
- Identifying what information is needed to submit a clean claim.
- Practicing scenario-based billing and coding questions under timed conditions.
What Is the Revenue Cycle and Why Does It Matter for the CBCS?
The revenue cycle is the financial backbone of every healthcare organization, and it is the central framework tested on the CBCS exam. A billing and coding specialist must understand what happens before the patient visit, during documentation and coding, after claim submission, and after payer adjudication.
The 7 Stages of the Revenue Cycle
| Stage | Key Activities |
|---|---|
| 1. Patient Scheduling & Pre-Registration | Collect demographics, verify insurance, obtain referrals |
| 2. Registration & Check-In | Confirm identity, collect copays, sign consent forms |
| 3. Charge Capture | Document services rendered using encounter forms and progress notes |
| 4. Medical Coding | Assign ICD-10-CM diagnosis codes, CPT procedure codes, and HCPCS Level II codes |
| 5. Claim Submission | Complete CMS-1500 paper claims or 837P electronic claims, then transmit to payer or clearinghouse |
| 6. Payment Posting & Adjudication | Interpret remittance advice, post payments, and apply adjustments |
| 7. Denial Management & Appeals | Analyze rejections, correct errors, resubmit claims, and file formal appeals |
Each stage connects directly to one or more CBCS exam domains. Insurance eligibility maps to the front-end stages. Coding and guidelines map to charge capture and code assignment. Billing and reimbursement maps to claim submission, adjudication, payment posting, and denial management.
What Are the CMS-1500 Form Basics Tested on the CBCS?
The CMS-1500 form is the standard paper claim form used by physicians and other non-institutional providers to bill Medicare and many other payers. CMS identifies the 837P Professional transaction as the standard electronic format used by healthcare professionals and suppliers to transmit professional claims electronically.
The CMS-1500 has 33 numbered fields organized into key sections. The CBCS exam expects candidates to know the most critical fields and how information flows into a professional claim.
| Box | Field Name | What It Contains |
|---|---|---|
| Box 1 | Insurance Type | Medicare, Medicaid, TRICARE, CHAMPVA, Group, FECA, Other |
| Box 2 | Patient Name | Must match insurance card exactly |
| Box 21 | Diagnosis Codes | ICD-10-CM codes establishing medical necessity |
| Box 24A | Date of Service | When the service was provided |
| Box 24B | Place of Service | 2-digit POS code, such as 11 for office or 21 for inpatient hospital |
| Box 24D | CPT/HCPCS Codes | Procedure or service codes with modifiers |
| Box 24G | Days or Units | Quantity of services rendered |
| Box 24J | Rendering Provider NPI | National Provider Identifier of the performing clinician |
| Box 33 | Billing Provider Info | Name, address, NPI, and Tax ID of billing entity |
Clean claims depend on correct demographic information, valid insurance data, accurate diagnosis and procedure coding, correct modifiers, proper provider identifiers, and payer-specific requirements.
What Coding Systems Does the CBCS Exam Cover?
The CBCS exam tests foundational knowledge of three major coding systems. Because candidates can no longer bring printed coding manuals into the testing room, preparation should focus on understanding what each code set is used for and how coding logic is applied.
ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification)
- Purpose: Classifying diagnoses and reasons for healthcare encounters.
- Structure: 3–7 character alphanumeric codes, such as E11.65 for Type 2 diabetes mellitus with hyperglycemia.
- Key conventions: Placeholder "X" characters, 7th-character extensions, code-first notes, use-additional-code notes, Excludes1 and Excludes2 notes.
- CBCS focus: Coding to the highest level of specificity and sequencing diagnoses correctly.
CPT (Current Procedural Terminology)
- Purpose: Reporting medical procedures and services performed by providers.
- Structure: 5-digit numeric codes organized into sections such as Evaluation & Management, Anesthesia, Surgery, Radiology, Pathology/Laboratory, and Medicine.
- Key conventions: Add-on codes, modifier usage, parent codes, standalone codes, and indented codes.
- CBCS focus: Selecting procedure codes based on documentation and applying modifiers when supported.
HCPCS Level II (Healthcare Common Procedure Coding System)
- Purpose: Coding supplies, equipment, drugs, and services not covered by CPT.
- Structure: One letter followed by four digits, such as J-codes for certain drugs and injections.
- Key conventions: Alphanumeric code categories, temporary codes, durable medical equipment codes, and payer-specific use.
- CBCS focus: Identifying when HCPCS Level II codes apply, especially for Medicare and Medicaid claims.
How Is the CBCS Exam Scored?
The CBCS uses NHA's scaled scoring system. Raw scores are converted to a scale of 200–500, with a passing score of 390. Scaled scoring helps ensure fairness across different versions of the exam.
Because NHA uses scaled scoring, a score of 390 does not mean you need exactly 78% of questions correct. The actual raw-score requirement may vary slightly depending on the difficulty of the exam form.
The 25 pretest items on the exam are experimental questions being evaluated for future exams. They do not count toward your score, but you will not know which items are pretest. Treat every question as scored.
How Does the CBCS Compare to a Coding-Focused Credential?
If you are deciding between an entry-level billing-and-coding credential and a more coding-focused credential, the right choice depends on your career goal. The CBCS is designed for candidates who want a fast entry into revenue cycle, claims, billing, front-office insurance, and foundational coding roles.
| Feature | NHA CBCS | Coding-Focused Credential |
|---|---|---|
| Primary Focus | Revenue cycle, billing, claims, compliance, and foundational coding | Deeper outpatient coding, auditing, and documentation review |
| Best For | Career starters and billing-focused roles | Candidates pursuing long-term coding specialization |
| Exam Style | Multiple-choice, scenario-based billing and coding knowledge | Often longer and more code-intensive |
| Reference Materials | CBCS manuals are not permitted on current exams | Some coding-focused exams may allow manuals depending on the certifying body |
| Career Target | Billing specialist, claims processor, patient account representative, revenue cycle specialist | Medical coder, coding auditor, documentation review specialist |
| Study Priority | Revenue cycle workflow, payer rules, claims, compliance, and code-set logic | Advanced code selection, guideline navigation, specialty coding, and audits |
A practical strategy is to start with CBCS if you want an accessible first credential for billing, claims, and revenue cycle work. Later, you can add a more specialized coding credential if your career goal shifts toward dedicated coding, auditing, or compliance roles.
