NHA CBCS Pass Rate 2026: 71.33% — What the Data Shows

What is the CBCS exam pass rate?

According to the National Healthcareer Association (NHA), the Certified Billing and Coding Specialist (CBCS) exam had a pass rate of 71.33% in its most recent annual report, with 7,878 candidates passing out of 18,006 who tested. In other words, roughly seven in ten first-time-and-repeat test-takers earn the credential each year — a healthy pass rate, but one that still leaves nearly three in ten candidates short. Understanding why those candidates fall short is the fastest way to make sure you land in the passing majority.

How the CBCS exam is scored

The CBCS is a 100-question exam that you have 180 minutes to complete. That works out to a little under two minutes per scored item — comfortable pacing, but not so generous that you can afford to stall repeatedly on unfamiliar coding scenarios. NHA reports your result as a scaled score rather than a raw percentage correct: scaled scores range from 200 to 500, and you must reach a scaled passing score of 390 or higher to pass.

Scaling matters because it accounts for small differences in difficulty between exam versions. Two candidates who see different question sets are held to the same standard of competence, not the same number of raw correct answers. Practically, this means you can't reverse-engineer an exact "how many can I miss" figure — you should aim to demonstrate solid mastery across every content area rather than banking on a comfortable cushion.

What drives pass and fail outcomes

With a 71.33% pass rate, the gap between passing and failing usually comes down to preparation depth rather than raw ability. The candidates who struggle tend to have thin exposure to real coding workflows — ICD-10-CM, CPT, and HCPCS conventions, claim life cycles, payer rules, and compliance concepts such as HIPAA. Because the exam is scaled to a fixed 390 threshold, uneven preparation is punishing: strength in one domain won't rescue a weak one if your overall scaled score lands below the line.

NHA builds a genuine second chance into the process. If you don't pass, you may retake the exam after a 30-day waiting period, and candidates are allowed up to three attempts, with that minimum 30-day wait between each. That structure rewards candidates who treat a first-attempt miss as a diagnostic — reviewing weak domains during the wait — rather than immediately re-sitting the same material cold.

How to improve your odds

Because eligibility for the CBCS only requires a high school diploma or GED, many candidates come to the exam without formal coding experience — which makes structured preparation the single biggest lever on your outcome. NHA itself supports candidates with study guides and practice tests, and working through realistic questions under timed conditions is the closest proxy for the actual scored exam. A focused prep plan should:

• Rehearse under the real clock — 100 questions in 180 minutes — so pacing becomes automatic.
• Target the domains you score weakest on, since a scaled 390 rewards balanced competence.
• Build fluency with code-set conventions and claim scenarios rather than memorizing isolated facts.

After you pass: keeping the credential

Earning the CBCS is the beginning, not the end. The certification is valid for two years, and to stay current you must renew every two years by completing 10 continuing education (CE) credits within each two-year period. If a certification lapses, NHA permits reinstatement within one year of the expiration date, though reinstatement requires evidence of 15 CE credits plus the applicable fees — a meaningfully steeper bar than routine renewal, and a strong reason to track your CE well before your expiration date.

Why the CBCS credential carries weight

The credential's value rests partly on the organization behind it. NHA has been serving allied health since 1989 and offers eight allied health certifications in total, of which CBCS is one. The program is accredited by the National Commission for Certifying Agencies (NCCA), the accreditation that signals an exam meets recognized standards for validity and fairness — which is also why the scaled-scoring and fixed-threshold approach described above isn't arbitrary but part of a defensible testing standard. At a registration cost of $129, the CBCS is an accessible entry point into medical billing and coding, and the 71.33% pass rate confirms that candidates who prepare deliberately have a strong probability of clearing it.
