Medical Billing Certification: CPB, CBCS, and What Employers Ask For (2026)

Updated September 13, 2026 · Medical Billing Path Editorial Team

Key takeaway: Medical billing certification is optional in law and expected in hiring. The billing-specific exam is AAPC’s CPB. NHA’s CBCS covers billing and coding together. Many practices also accept the CPC. No state licenses billers.

If you searched “billing certification” because coding looks like too many books, stay here. You still need enough CPT and ICD-10-CM to read a claim, and the first job may still be on site. This site is not affiliated with AAPC or NHA.

There is no state license with this name

No state licenses medical billers. “Medical billing certification” in an ad is either a third-party exam (CPB, CBCS, sometimes CPC) or a school diploma. Only the third-party exam is what employers usually mean. This site is not affiliated with AAPC, NHA, or AHIMA.

How to choose in ten minutes

Open ten “medical biller” postings in your city. Tally CPB, CBCS, CPC, and “or equivalent.” Match a program to the winner. If the tally is mixed, a combined certificate that names CBCS or CPC matches more of those ads.

A school diploma is not a CPB or CBCS

“Medical billing certification programs” in an ad may be a school diploma with no third-party exam. Ask “Which body issues the exam, and do your graduates sit it?” If the answer is a shrug, keep shopping. Medical billing programs has the curriculum list.

Frequently asked questions

What certification do I need for medical billing?

No state requires a license. Employers often ask for AAPC’s CPB, NHA’s CBCS, or the CPC. Read local postings. A school completion certificate is not the same as those exams.

Is there a medical billing certification online?

You can complete a billing program online and sit the CPB or CBCS as those bodies currently deliver them (testing center or online proctoring, which changes). Confirm current delivery with AAPC or NHA. Online class is not a remote job guarantee.

CPB or CBCS?

CPB is AAPC and billing-focused. CBCS is NHA and combined billing and coding. Career schools often map to CBCS. Let the program’s exam and your local ads decide.

Do I need the CPC to bill?

Not always. Many billing jobs accept CPB or CBCS. Small practices that want one person to code and bill often list the CPC. Combined work is common.

How long does billing certification take?

A billing or combined certificate commonly runs about four to twelve months full time, then the exam appointment. Part-time takes longer. The exam is separate from the school.

How much does medical billing certification cost?

Program prices vary; compare total published cost including manuals. Exam and membership fees are set by AAPC or NHA and change. We do not quote those amounts. See the program cost guide and the certifying body’s site.
