NHA CPT vs CBCS: Which Certification Fits Your Career?
The Certified Phlebotomy Technician (CPT) and Certified Billing and Coding Specialist (CBCS) are both two year credentials from the National Healthcareer Association (NHA), but they test different jobs. As of October 2026, the CPT has 120 questions (100 scored, 20 unscored) and a 2 hour limit, while the CBCS has 125 questions (100 scored, 25 unscored) and a 3 hour limit. Both use a passing scaled score of 390 on a 200 to 500 scale, both renew every 2 years for $195 plus 10 continuing education (CE) credits, and both are delivered through PSI test centers, at your school or sponsoring organization, or by live remote proctoring. The CPT is a hands on clinical credential that requires documented evidence of at least 30 venipunctures and 10 capillary or finger sticks. The CBCS is an administrative credential, closed book since September 24, 2024, with 65 of its 100 scored items in coding and billing. NHA does not publish an exam fee for either credential on its public pages. Choose by the work you want to do, not by difficulty.

What the Table Says About Two Different Careers
The shared rows (scoring, renewal, retake rules, delivery) come from the same NHA Candidate Handbook, so neither credential is cheaper to keep or easier to retake. The differences are time, item mix, hands on documentation, and what the exam measures.
A certified phlebotomy technician collects and processes blood specimens. The CPT test plan reflects that work directly: 28 scored items cover routine blood collections, 26 cover safety and compliance, 20 cover patient preparation, 14 cover processing, and 12 cover special collections. You spend most of a shift with patients and specimens. Our guide to what’s on the NHA CPT exam breaks the blueprint down topic by topic.
A certified billing and coding specialist works with records and payers rather than patients. The CBCS test plan puts 33 scored items on billing and reimbursement, 32 on coding and coding guidelines, 20 on insurance eligibility and payer requirements, and 15 on the revenue cycle and regulatory compliance. The job centers on turning clinical documentation into accurate claims and keeping the practice compliant. It is desk based. See what’s on the CBCS exam for the full domain breakdown.
Eligibility Routes Compared
Both credentials share the same NHA framework, as of October 2026. Every candidate needs a high school diploma or equivalent, or must be scheduled to earn one (up to 18 months on NHA’s certification pages). NHA then offers two pathways; CPT requirements and CBCS requirements cover each credential’s specifics.
Pathway 1, training program. You complete a training program in the field within the past 5 years. The Candidate Handbook lists several routes: an accredited or state recognized institution, a U.S. Department of Labor registered apprenticeship, formal military training, the coursework portion of an employer based program (training finished within 180 days of the exam date), or the coursework portion of a program with an externship pending (finished within 90 days of the exam date). A score earned on one of the last two routes is held until the training is reported complete.
Pathway 2, work experience. You have 1 year of supervised work experience in the field within the last 3 years, or 2 years within the last 5 years. No formal program is needed.
The CPT adds one requirement the CBCS does not have: evidence that you have performed at least 30 venipunctures and 10 capillary or finger sticks on live individuals. This is the clearest practical barrier between the two credentials: a CBCS candidate needs only the training or work history.
Exam Experience: Clinical Judgment vs Closed Book Reasoning
The CPT is the shorter exam. Its items test procedure: order of draw, site selection, handling complications, infection control, and specimen processing. The CBCS gives you more time because many items require working through a scenario step by step, such as selecting the right code or deciding why a claim was denied.
The CBCS has been closed book since September 24, 2024. Coding manuals are not allowed in the testing room, and the reference information a coding question needs is provided in the question itself. Study advice built around manual lookup speed no longer matches the exam; understanding coding logic matters more. For the CPT, the handbook states that no reference books are allowed during any NHA examination.
Scoring works the same way on both. Score reports post to your NHA account within 48 hours for PSI test center and live remote proctoring sittings, and show each major content area as above, near, or below the passing standard, which helps direct a retake. NHA’s 2024 pass rate report lists 75.96% passing for the CPT (57,457 exams administered) and 73.82% for the CBCS (6,905 exams administered), as of October 2026. The rates are computed from all 2024 examinations, and NHA does not split first attempts from retakes. The two exams draw different candidate populations, so treat the figures as rough context, not a difficulty ranking.
Cost and Renewal
NHA does not list a fixed exam fee for either credential on its public certification pages. The fee is shown in the NHA Shop and at registration, so check the number there. Each attempt, including a retake, requires the full exam fee, with a 30 day wait between attempts and a 1 year wait after the third.
Holding either credential costs the same. As of October 2026, NHA’s renewal page lists $195 every 2 years, which NHA describes as about $8 per month, plus 10 CE credits. Two hours of qualifying CE equal 1 credit. CE credits can count toward more than one NHA certification, so someone holding both needs 10 credits for the cycle, not 20. A credential that lapses between 30 days and 1 year costs $391.50 to reinstate ($292.50 renewal plus a $99 reinstatement fee) and needs 15 CE credits. After 1 year, reinstatement is not available and you must retake the exam.
Which One Fits Whom
If you like working with people, can tolerate blood and needles, and want to be on your feet, the CPT matches that job. If you prefer quiet, detail oriented work, are comfortable with medical terminology and insurance rules, and want an administrative office role, the CBCS matches that one. The two are not ranked against each other; they open different doors.
Some people hold both, since CE credits can be shared across NHA certifications. That suits someone at a clinic who covers both specimen collection and billing tasks. If you are unsure, the eligibility rows decide quickly: with no documented live draws yet, the CBCS is the route you can apply for sooner.
Whichever you choose, build your study plan around the weights above: routine blood collections and safety and compliance carry 54 of 100 scored CPT items, and billing and reimbursement plus coding carry 65 of 100 scored CBCS items.

Frequently Asked Questions
Is the NHA CPT or CBCS exam longer?
The CBCS is longer. As of October 2026, it allows 3 hours (180 minutes) for 125 questions, while the CPT allows 2 hours (120 minutes) for 120 questions. Each exam has 100 scored questions plus unscored pretest items that are not identified during the test.
Do the CPT and CBCS have the same passing score?
Yes. NHA scores its exams on a scaled range of 200 to 500 and requires a scaled score of 390 or higher to pass, according to the Candidate Handbook.
Can I take the CBCS without hands on experience, unlike the CPT?
Yes. The CBCS has no procedure log; it needs only the diploma plus training or supervised work experience described above. The CPT also requires documented evidence of at least 30 venipunctures and 10 capillary or finger sticks on live individuals.
Does it cost more to renew one than the other?
No. NHA lists the same renewal terms for both: $195 every 2 years and 10 CE credits, as of October 2026. CE credits can be applied to more than one NHA certification.
