Certified Billing and Coding Specialist (NHA) Exam: Full Comparison

The Certified Billing and Coding Specialist (CBCS) credential from the National Healthcareer Association (NHA) validates skills in medical billing, coding, and claims processing. If you are weighing it against a clinical certification like the CCMA or CMA, or a coding-focused credential like the CPC, the right choice depends on the kind of role you want: administrative and revenue-cycle work versus hands-on patient care. This page compares the CBCS against three commonly considered exams so you can pick the path that matches your goals.

At a glance

All four credentials sit in the allied-health field, but they split into two lanes: administrative/coding (CBCS, CPC) and clinical medical assisting (CCMA, CMA). Choosing between them is mostly a question of scope, not prestige.

Scope of each exam

• Certified Billing and Coding Specialist (CBCS, NHA): Focused on the revenue cycle — medical coding (ICD-10-CM, CPT/HCPCS), claims submission, insurance/payer rules, compliance, and billing workflows. It is a broad billing-and-coding overview credential. The CBCS exam has 100 scored questions and a 180-minute time limit.
• Certified Professional Coder (CPC, AAPC): The most code-specialized of the four. It goes deep on physician/outpatient coding accuracy across ICD-10-CM, CPT, and HCPCS Level II, with heavy emphasis on applying coding guidelines to case scenarios. It is generally considered the gold-standard coding credential for coder roles.
• Certified Clinical Medical Assistant (CCMA, NHA): Clinical, not administrative — covers patient care fundamentals such as taking vitals, assisting with exams, phlebotomy, EKGs, and basic pharmacology, along with some administrative duties.
• Certified Medical Assistant (CMA, AAMA): Also clinical, spanning both clinical and administrative competencies for medical assistants, with a strong emphasis on ambulatory patient care.

Difficulty

Difficulty depends on the skill being tested rather than a single ranking. The CPC is widely regarded as the most demanding because it requires precise, guideline-driven coding on complex scenarios. The CBCS is broad but more introductory, making it an accessible entry point into billing and coding. The CCMA and CMA are clinically oriented, so their difficulty comes from mastering patient-care procedures rather than coding rules — the CMA (AAMA) in particular is known for rigorous eligibility and content standards.

Who each is for

• CBCS — Best for people who want an administrative, back-office role in billing, coding, or claims and want a recognized entry-level credential to get started.
• CPC — Best for those who want to specialize as a professional medical coder and pursue coder-specific roles.
• CCMA — Best for those who want a hands-on clinical role assisting providers with direct patient care.
• CMA — Best for those seeking a widely recognized clinical medical-assistant credential, often through an accredited program.

Prerequisites

Prerequisites differ by certifying body and program, and can change, so always confirm current eligibility directly with each organization. In general, the CBCS and CCMA (NHA) are typically pursued after completing a relevant training program or with qualifying work experience. The CMA (AAMA) is known for requiring graduation from an accredited (CAAHEP/ABHES) medical assisting program. The CPC (AAPC) can be taken by candidates who prepare through AAPC coursework, though AAPC recommends coding experience and confers full certification status once an experience requirement is met.

Cost note

Fees vary by organization and are subject to change; verify the current price with each certifying body before registering. As one grounded reference point, the CBCS exam fee is $129.
