Which Medical Billing and Coding Certification Should You Get? (2026 Comparison)

Updated September 2, 2026 · Medical Billing Path Editorial Team

Advertising disclosure: listings marked "Sponsored Listings" are paid placements. See how we make money.

Key takeaway: Pick the certification by the job you want, not by the exam that sounds easiest. Physician practice and outpatient coding: CPC, CCA, or CBCS. Billing and revenue cycle: CPB or CBCS. Hospital inpatient coding: CCS. Health information roles with a two-year degree: RHIT. Then choose a program that maps to that exam.

You do not need every credential. You need the one that shows up in the postings you would actually apply to. Finishing a program is not the same as being certified, and AAPC’s CPC comes with an apprentice designation (CPC-A) until you document experience. This site is not affiliated with AAPC, AHIMA, NHA, or CAHIIM. Exam formats, eligibility, and fees change; confirm current rules on each body’s site. We do not quote exam fees.

The comparison

Credential	Body	Typical use	Prerequisite (as published)	Apprentice period	Setting emphasis
CPC	AAPC	First coding job in a practice or outpatient center	None required; education recommended	Yes (CPC-A)	Physician, outpatient
CCA	AHIMA	First coding job, no apprentice label	High school diploma	No	Fundamentals across settings
CBCS	NHA	Combined billing and coding at entry level	Diploma plus training or experience	No	Practice billing and coding
CPB	AAPC	Billing and revenue cycle roles	None required	No	Billing
CCS	AHIMA	Hospital inpatient coding	Pathways combining credentials, coursework, or experience	No	Inpatient and outpatient
RHIT	AHIMA	Health information roles	CAHIIM-accredited degree	No	Health information management

Confirm eligibility and exam format with the certifying body before you register. Summaries on this site are descriptive, not official policy.

A decision path you can finish in ten minutes

Do you want to code, bill, or manage health information? Billing: CPB or CBCS. Health information: RHIT, which means a CAHIIM-accredited degree. Coding: continue.
Physician practice or hospital? Practice or outpatient: CPC or CCA. Hospital inpatient: CCS, usually after the CCA or a degree, not as a first exam.
Does the apprentice period bother you? If yes, the CCA avoids it. If you are fine starting as CPC-A, the CPC is the credential most often named in practice postings.
Which exam is your intended program built around? Match the program to the answer above. If admissions cannot name an exam, pick a different program.

Read the postings, not the brochure

Before you commit, search “medical coder” and “medical biller” plus your city. Open ten listings. Tally which credentials appear in the requirements. Employers, not certifying bodies, decide which letters matter where you live.

A military spouse who will move in two years should weight nationally recognized credentials (CPC, CCA, CCS, RHIT) over a school-only certificate. A parent who needs the shortest path into a local clinic can let those ten postings pick the exam, then find a program that maps to it.

Open-book exams, renewal, and second credentials

The exam is open-book for the manuals, and it is still hard. Speed with the books is a skill. Programs that skip timed practice leave you short.
Membership and renewal are separate from passing. AAPC, AHIMA, and NHA each have their own cycle, usually two years, with continuing education units. Budget time for that after you are hired.
Holding two credentials is common later, not on day one. A CPC plus a CCS is a career move after you have inpatient exposure. Do not pay for a second exam until a job or a posting asks for it.
A school “exam voucher” is not a pass. It is a prepaid attempt. Ask whether unused vouchers expire and what happens after a fail.

Which certification pays the most?

BLS does not publish pay by credential. There is no official “CPC salary” or “CCS salary” table. The occupation that includes billers and coders had a median of $51,140 in May 2025, with a 10th percentile of $37,000 and a 90th of $81,150. Across the industry, hospital inpatient and specialty coding (often CCS-level work) are described as sitting higher in that range than entry billing, but that is observation, not a BLS split. Pick the credential the job you want names.

How the exams differ in plain language

CPC (AAPC). Deep on CPT, the procedure codes used in physician offices. Open manuals. The one you will see named most often in outpatient job ads. Details: CPC guide.

CCA (AHIMA). Fundamentals across hospital and physician settings, including a first look at ICD-10-PCS. No apprentice label. A common first AHIMA credential on the way to the CCS. Details: CCA guide.

CCS (AHIMA). Hospital coding in earnest: ICD-10-PCS, DRG assignment, and scenario coding. Most people are not ready for this as a first exam. Details: CCS guide.

CBCS (NHA). Combined billing and coding at entry level. Common in career-school programs and accepted in many practices. For coding-only hospital roles, compare it with CPC or CCA first. Details: CBCS guide.

CPB (AAPC). Billing depth: payer rules, claims, denials, collections. Pair it with a coding credential later if you do both. Details: CPB guide.

RHIT (AHIMA). Not a coding-only credential. Health information management, including coding, tied to a CAHIIM-accredited degree. Details: RHIT guide.

Questions to ask before you register

Does the program’s syllabus map to this exam’s published blueprint?
Do graduates sit for this exam, and will the school say how many did last year?
Are current-year CPT, ICD-10-CM, and HCPCS manuals included, or do you buy them?
For the CPC: do you understand you will be CPC-A until experience is documented?
For the RHIT: is the program CAHIIM accredited, not just the college?

Frequently asked questions

Which medical coding certification do employers ask for?

In physician practice and outpatient postings, the CPC is the credential most often named, with the CCA and CBCS frequently accepted as equivalents. In hospital health information departments, the CCS and RHIT are more often requested. The reliable way to decide is to read ten job postings for the roles you want in your area and count which credentials appear.

Can I hold more than one certification?

Yes, and experienced coders often do, for example a CPC plus a CCS, or a CPB plus a CPC. Each is renewed separately with continuing education. Confirm current renewal rules with AAPC, AHIMA, or NHA.

Should I get certified before or after I find a job?

Most entry-level postings ask for certification or eligibility, so candidates usually certify first. Some employers hire graduates who are scheduled to test. The CPC’s apprentice designation means even certified new coders start as CPC-A.

Is certification required by law?

No state licenses medical billers or coders, and no law requires certification. In practice most employers ask for one because it is the standardized proof that you can code or bill accurately.

Does the CCA have an apprentice period like the CPC?

No. Unlike AAPC’s CPC-A, AHIMA’s CCA has no apprentice label. That is one reason some new coders choose the CCA first, especially if they are aiming at hospital settings where AHIMA credentials are well known.

Can I take the RHIT without a degree?

No. AHIMA requires graduation from a CAHIIM-accredited health information program. A coding certificate does not make you eligible. Check CAHIIM accreditation before you enroll in any two-year program for this credential.

Which certification should a career changer get first?

If you want a physician office or billing-company job, start with the CPC, CCA, or CBCS, matching whatever exam your program is built around. If you want hospital inpatient coding, plan for the CCS after an entry credential or a health information degree. Do not pick an exam because it sounds easier.
