Certified Clinical Medical Assistant (NHA) Exam: Full Comparison

If you're weighing the Certified Clinical Medical Assistant (CCMA) exam from the National Healthcareer Association (NHA) against other allied-health credentials, it helps to see them side by side. The CCMA is a clinical-plus-administrative credential, while the exams below range from a rival clinical MA certification to specialized coding and billing credentials. This page compares scope, difficulty, ideal candidates, and prerequisites so you can pick the path that fits your career goals.

At a Glance

The CCMA is a broad medical-assisting credential covering both patient-facing clinical tasks and front-office duties. The exams it's most often compared with fall into two buckets: another general medical-assistant certification (CMA from AAMA) and coding/billing specialist credentials (CPC and CBCS).

• Certified Clinical Medical Assistant (NHA) — CCMA: The exam has 150 scored questions and a 180-minute time limit, with a scaled passing score of 390. The exam fee is $165.
• Certified Medical Assistant (AAMA) — CMA: A competing general medical-assistant credential, also covering clinical and administrative competencies.
• Certified Professional Coder (CPC) — AAPC: A specialist credential focused on translating clinical documentation into medical codes.
• Certified Billing and Coding Specialist (NHA) — CBCS: A specialist credential focused on the billing and coding revenue cycle.

Scope

The CCMA and CMA (AAMA) both certify hands-on clinical skills (vitals, phlebotomy, EKG, assisting with procedures, patient intake) combined with administrative competencies. In contrast, the CPC and CBCS are non-clinical: they certify the ability to work with documentation, code sets, claims, and reimbursement rather than direct patient care. If you want to work chairside with patients, a medical-assistant credential fits; if you prefer a desk-based revenue-cycle role, a coding or billing credential fits.

Difficulty

Because the CCMA covers a wide breadth of clinical and administrative topics, its difficulty comes from range rather than depth in any single area. The CMA (AAMA) is comparably broad and is often regarded as rigorous within the MA field. The CPC is widely considered the most demanding of these four because it requires detailed mastery of multiple code sets (such as CPT, ICD, and HCPCS) and coding guidelines. The CBCS is more narrowly scoped than the CPC, making it a common entry point into coding and billing.

Who Each Is For

• CCMA (NHA): Aspiring medical assistants who want a versatile, employer-recognized clinical + administrative credential.
• CMA (AAMA): Medical assistants — often graduates of accredited MA programs — seeking the AAMA's long-established clinical credential.
• CPC (AAPC): Individuals aiming for a dedicated medical-coding career, including outpatient/physician coding roles.
• CBCS (NHA): Those entering the billing and coding side of the revenue cycle who want an accessible starting credential.

Prerequisites

Eligibility requirements differ by certifying body and can change, so confirm the current criteria directly with each organization before applying. Generally, medical-assistant credentials expect a mix of relevant education and/or hands-on training, while coding and billing credentials emphasize coursework or experience with code sets and claims. Always verify eligibility, required documentation, and any experience or training pathways with the issuing organization.
