CNA to Medical Coder (Medical Billing and Coding): Training, Certification, and How to Switch
Medical coders earn a median of $51,140, $8,880 more than CNAs, after a 4 to 12 month certificate, often fully online, and a certification exam such as the CPC or CCA. You trade patient care for a desk, and with a few years of experience many coders work from home.

Can a CNA Become a Medical Coder?
Fast answer
Yes, and it is one of the cheapest, most flexible ways off the floor. No program requires a CNA, and your medical vocabulary gives you a head start. Coders earn a median of $51,140, and the training is often online and done in under a year. The catches: the raise is smaller than on the two-year paths, the first coding job is the hardest step, and remote work usually comes after a few years. Skip it if you want to keep caring for patients (PTA or LPN) or need a raise within weeks (phlebotomy).
How does medical coding compare to other paths from CNA?
| Path | Training | Median pay | Best for |
|---|---|---|---|
| Phlebotomist | 8–16 weeks | $45,230 | Fastest pivot, a specific technical skill |
| This guideMedical coder | 4–12 months | $51,140 | Leaving bedside care for desk work, with remote work likely after a few years |
| Medical assistant | 9–24 months | $45,690 | Clinic hours, a broader clinical and admin role |
| LPN / LVN | 12–18 months | $64,400 | Solid income and access to the nursing ladder |
| Surgical tech | 12–24 months | $64,650 | The operating room, with a narrower ladder |
| Ultrasound tech | 12–24 months | $96,590 | Highest non-nursing pay, less lifting |
| X-ray tech | 18–24 months | $80,110 | Stable allied health pay with a clean credential ladder |
| Physical therapist assistant | 2 years | $68,380 | A licensed rehab role and a big raise, without nursing school |
| Registered nurse | 2–4 years | $97,550 | Maximum long-term upside and the broadest career |
Median pay: BLS national estimates for each occupation. Training: typical program length.
Who this path fits best
- CNAs whose body needs a break. No lifting, no transfers, no 12-hour shifts on your feet: coders work at a computer.
- CNAs who are good with detail. If you were the one who charted carefully, coding rewards the same habit all day.
- CNAs who need a cheap, flexible route. Many programs are online and some are self-paced, so you can keep working while you study.
- CNAs ready for a slow start. The first job may be onsite and pay little more than CNA work. Remote work and higher pay come with experience.
Who should probably pick a different path
Want to keep helping patients, for a bigger raise? PTA takes about two years and pays far more at the median.
CNA to PTA → 2 years · $68,380
Need a raise within weeks? Phlebotomy training is short, and the job stays hands-on.
CNA to Phlebotomist → 8–16 weeks · $45,230
Want admin work but some patient contact? Medical assistants mix front desk, records and clinical tasks.
CNA to Medical Assistant → 9–24 months · $45,690
Want a big raise and the nursing ladder? LPN takes 12 to 18 months and leads on to RN.
CNA to LPN → 12–18 months · $64,400
Want the highest long-term ceiling? RN opens management, NP and most other healthcare ladders.
CNA to RN → 2–4 years · $97,550
Every year at CNA pay is about $8,880 below the medical coder median. Compare medical billing and coding programs in your state:

What Your CNA Experience Counts For
It helps you learn faster and get noticed, but it is not coding experience. Nothing in coding requires a CNA, and no program we found gives credit for one.
| Area | Does a CNA help? | What it means |
|---|---|---|
| Medical terms and anatomy | Yes | AAPC says coding training needs a high-level knowledge of medical terminology, anatomy and pathophysiology. You know the words, but you still take the courses. AAPC |
| Reading charts | Yes | Coders work from what doctors and nurses write. Years of charting make that record familiar. |
| Getting hired | Sometimes | BLS says a high school diploma plus experience in a healthcare setting is enough for some positions. Your employer's billing or records office is a good first place to ask. BLS |
| Removing the CPC "A" | No | AAPC counts only work using the CPT, ICD-10-CM or HCPCS code sets. CNA work does not use them. AAPC |
| School credit | No | No coding program we found waives a course or gives credit for a CNA certificate. |
AAPC names healthcare staff moving into coding from administrative or clinical support positions as one of the groups its CPC is for. The other half of the job, the code books, guidelines and payer rules, is new to almost everyone, clinical background or not.
CNA vs. Medical Coder: What Changes
You give up patient care and moving around all shift. You get a desk, productivity targets and, in time, often a home office.
| CNA | Medical codermedical records specialist |
|---|---|
| Core work | |
| ADLs (bathing, dressing, feeding), vital signs, repositioning | Reading the medical record and assigning diagnosis and procedure codes for billing |
| Patient contact | |
| All shift | None. BLS calls it one of the few health jobs with no hands-on patient care |
| Main work setting | |
| Nursing homes, hospitals, assisted living | Hospitals, physician offices, billing and management companies, often from home once experienced |
| Hours | |
| 8 or 12-hour shifts, nights, weekends, holidays | Mostly full time at a computer. Hospitals that never close may need nights or weekends |
| Physical demands | |
| Heavy lifting and transfers | Sitting at a computer all day |
| Training length | |

What Do Medical Coders Do?
They turn each patient visit into standard codes, so the provider can bill for it and the data can be counted.
| Task | What it involves |
|---|---|
| Review the record | Read what the provider documented: the diagnosis, the tests and the procedures. |
| Assign the codes | Diagnosis codes (ICD-10-CM) and procedure codes (CPT and HCPCS Level II), following the coding guidelines. |
| Work with billing | BLS describes coders as the liaison between healthcare providers and billing offices. BLS |
| Meet the targets | Employers set productivity and quality targets, and remote coders often sign a telecommuting agreement. AAPC |
Medical Billing vs. Coding: What's the Difference?
Coders translate the chart into codes. Billers use the codes to get the provider paid. In small practices, one person often does both.
| Medical coding | Medical billing |
|---|---|
| The job | |
| Read the medical record and turn diagnoses and procedures into standard codes | Work between patients, providers and insurance companies to get the provider paid |
| Daily tasks | |
| Assigning and checking codes | Claims, insurance rules, payment posting and follow-up |
| Credentials | |
| CPC (AAPC), CCA and CCS (AHIMA) | CPB (AAPC). NHA's CBCS covers billing and coding |
| Pay data | |
| $51,140 median (medical records specialists) | $48,500 median for billing and posting clerks, all industries |
Sources: AAPC, what is medical billing, AAPC CPB, NHA CBCS. Pay: BLS, medical records specialists and billing and posting clerks. BLS has no separate occupation for medical billers.
Most programs, including the program search on this page, teach billing and coding together, which suits jobs in smaller practices.
How Does Medical Coding Training Work?
Most people take a coding certificate or diploma, online or at a community college, then sit a certification exam. A degree is optional and comes later, if at all.
| Route | Length | Example | What to know |
|---|---|---|---|
| College certificate or diplomacommunity or technical college | About a year | Northcentral Technical College, 3 terms Program page | Often online. Community college programs usually accept federal aid, and some are approved by AHIMA's PCAP, such as Santa Fe College's certificate. |
| Self-paced online certificateuniversities, AAPC | 4–8 months | National University, within 6 months Program page | Start any time. National University says its certificates do not qualify for federal aid. |
| Associate degree in health informationCAHIIM-accredited | 2 years | Leads to the RHIT AHIMA | Not needed to start coding. A route into health information technology later. |
Courses cover medical terminology, anatomy and pathophysiology, the code sets and coding guidelines. AAPC's typical time to certify: 4 to 8 months.
Warning
There is no 4-week shortcut
AAPC itself says it is not possible to gain employable coding skills in just weeks, and warns readers to be wary of shortcuts. A course that promises a remote coding job within weeks is selling something else (see how to spot a bad program).
How Long Does It Take to Become a Medical Coder?
Plan for 4–12 months of training, then a job search. Remote work usually takes a few more years.
| Stage | Typical duration | What to know |
|---|---|---|
| Coursework and the CPC examself-paced | 4–8 months AAPC | AAPC's figure for most people |
| College certificate or diplomafull time | About a year | Part time takes longer: Madison College's online diploma is part time only |
| First coding job | Varies | New coders without experience can find it hard to land the first job (AAPC) |
| Removing the "A"CPC-A to CPC | Up to 2 years | Two years of coding work, or less with Practicode and an 80-hour course (see the first-job problem) |
| Remote work | 2–5 yearsof coding experience | What many employers ask before a remote position (AAPC) |
Can you keep working as a CNA?
Yes, more easily than on most paths. Northcentral Technical College, Madison College and National University all teach fully online, and self-paced courses fit around 12-hour shifts. That lets you keep your CNA income until the first coding job.
How Much Does Medical Coding School Cost?
The four online programs we checked cost $2,995 to $6,670, at in-state rates where they differ. Exams, membership and code books add several hundred dollars.
| Program | Cost | What it covers |
|---|---|---|
| National Universityonline professional certificate | $2,995certificate fee Program page | Self-paced, within 6 months. Prepares for the CPC. No federal aid. |
| Santa Fe CollegeFlorida, online certificate | $3,867tuition, residents Program page | 38 credits. Non-residents: $14,360. Books, lab fees, manuals and exams are extra. |

| Your employer | If you work for a hospital system, ask HR about tuition help and openings in its coding or billing office. |
CPC vs. CCA vs. CCS: Which Certification?
Employers may prefer a certification, or expect you to earn one soon after hiring (BLS). New coders usually start with AAPC's CPC or AHIMA's CCA. The CCS is for coders with experience.
| Credential | Who it is for | Exam | Fee | First-time pass rate |
|---|---|---|---|---|
| CPCAAPC | New and working coders. Without 2 years of coding experience you hold it as CPC-A AAPC | 100 questions, 4 hours, 70% to pass | $425–$499 AAPC | — |
| CCAAHIMA | Early-career coders. Needs a high school diploma AHIMA | 105 questions, 2 hours | $199–$299 | 62% |
| CCSAHIMA | Coders experienced with inpatient and outpatient records. Experience recommended, not required AHIMA | 107 questions, 4 hours | $299–$399 | 84% |
| COCAAPC | Outpatient hospital and facility coding AAPC | AAPC core exam | $425–$499 | — |
| CPBAAPC | Medical billing: claims, payment posting, insurance rules AAPC | AAPC core exam | $425–$499 | — |
| CBCSNHA | Billing and coding. Needs a program in the last 5 years or a year of supervised work NHA | NHA exam | See NHA | — |
Fees: the lower figure is one attempt (CPC) or the member price (AHIMA). Pass rates: AHIMA's latest published first-time rates. AAPC keeps your credential active with its $229 yearly membership and 36 continuing education units every two years.
Which one to choose depends on the jobs near you. Search coding job postings in your area and note which credential they ask for, and ask each program which exam it prepares you for.
The First-Job Problem: What CPC-A Means
Passing the CPC without two years of coding experience makes you a CPC-A, an apprentice. AAPC itself says new coders without experience can find it hard to land the first job.
The "A" does not expire as long as you keep your AAPC membership and continuing education, and you can work with it: AAPC lists jobs such as entry-level coder, coding trainee, physician office coder and billing and coding specialist (AAPC). To remove it, AAPC accepts one of four routes:
Two years of coding work.
Verified by employers, using the CPT, ICD-10-CM or HCPCS Level II code sets. Externships count.
One year of coding work plus education.
Practicode or an 80-hour coding course on top of a year on the job.
Practicode plus an 80-hour coding course.
No job needed. Practicode means at least 600 practice cases with an overall score of 70% or higher.
AAPC's Job-Ready Program.
A training package with a guaranteed externship of at least 160 hours for qualified graduates.
Source: AAPC, how to remove your A. Applications take 2 to 4 weeks to process.
Tip
Use your CNA job as the bridge. AAPC suggests working as a medical records clerk, receptionist or registration staff member to gain experience and make connections. If you work in a hospital or a large practice, its records, registration or billing office is the easiest place to start.
Is Medical Coding a Remote Job?
Often, once you have experience. Most experienced coders in AAPC's survey work from home, but many entry-level jobs start onsite or hybrid.
| Figure | What it says |
|---|---|
| 64.8%fully remote | Share of respondents in AAPC's salary survey who work fully remote. 19.8% work onsite and 15.4% hybrid AAPC |
| 13.7 yearsmedian in the field | The same survey's respondents are experienced: the remote share describes them, not new coders |
| 2–5 yearsof coding experience | What many employers ask before offering a remote position, though some let you gain it in-house AAPC |
For a CPC-A, AAPC's answer to "can I work remotely?" is "Sometimes": remote openings exist, but many entry-level roles start onsite or hybrid, and remote work becomes more common with experience and full CPC status.
How Much Do Medical Coders Make? Salary and Job Outlook
A median of $51,140 ($24.59 an hour), $8,880 more than CNAs, or about $740 a month. BLS projects 8% job growth over the decade.
BLS counts coders as medical records specialists. The lowest-paid 10 percent earn under $37,000, below the CNA median, and the top 10 percent over $81,150 (BLS). BLS expects about 14,000 openings a year.
| Where coders work | Median pay |
|---|---|
| Insurance carriers | $62,650 |
| Management of companies | $60,980 |
| Hospitals | $59,120 |
| Home health care | $48,510 |
| Physician offices | $47,120 |
| Nursing homes | $46,940 |
Source: BLS wage data by industry and the BLS handbook. Hospitals employ the most coders (28% of jobs), then physician offices (18%).
What new coders earn
In AAPC's salary survey, first-year coders averaged $45,377 and those with 2 to 4 years $51,073 (AAPC). Survey averages from AAPC members run above the BLS figures, so treat them as a guide. The point for a CNA: the raise grows with experience, not on day one.
Will AI replace medical coders?
BLS still projects growth, with a caveat. It projects 8% growth, much faster than average, but notes that AI tools that make coding more efficient may affect the demand for coders (BLS). Plan on learning the software, and on credentials that show judgment, not just speed.
What CNAs Often Underestimate About Medical Coding
The desk, the targets, and how slowly the first job and remote work come. Knowing this early helps you plan, not quit.
You sit at a computer all day.
After years on your feet, a desk can be a relief and an adjustment. BLS describes the work as typically done at a computer.
You will miss patients, or not.
BLS calls coding one of the few health jobs with no hands-on patient care. If patients are why you became a CNA, think hard about this.
Productivity and accuracy are measured.
Employers set coding productivity and quality targets, and remote coders often sign a telecommuting agreement. Focus and a quiet space matter.
The first job is the hardest step.
AAPC says new coders without experience can find it difficult to crack the job market. Plan for an onsite or hybrid first job, an externship, or a records or billing job first.
The first year may pay about what you earn now.
The BLS 10th percentile for coders is below the CNA median, and AAPC's first-year average is a few thousand dollars above it. The bigger raise comes with experience and credentials.
Keeping the credential costs money every year.
The CPC needs AAPC membership ($229 a year) and 36 continuing education units every two years.
Fast, cheap "remote coder" offers are a red flag.
AAPC says employable coding skills take more than a few weeks, and the FTC warns about pay-first medical billing business offers. See how to spot a bad program.
Where Does Medical Coding Lead Next?
Most coders grow through experience and more credentials. A health information degree opens the next level.
| Next step | What it takes |
|---|---|
| Full CPCthe "A" removed | Two years of coding work, or one of AAPC's other routes |
| CCSAHIMA | Experience with inpatient and outpatient records. AHIMA recommends coursework plus a year of coding, or two years of coding AHIMA |
| More AAPC credentialsCOC, CPB | Outpatient facility coding or medical billing, with AAPC's exam |
| Health information technologistmedian $68,020 | An associate degree from a CAHIIM-accredited health information program, then AHIMA's RHIT AHIMA |
| Medical or health services manager | BLS names it as a step up after a higher certification or a degree in health information technology |
Pay: BLS national median for health information technologists and medical registrars. Advancement: BLS.

Warning
How to spot a bad program or offer
The FTC warns that medical billing business offers charge hundreds or even thousands of dollars, that few buyers find clients, and that doctors usually use established billing firms. It also warns about job scams that sell training or certifications that turn out to be useless. In North Carolina, the Attorney General settled with an unlicensed school that sold billing and coding courses with false statements about job prospects. Walk away from a program that promises a remote job in weeks, will not publish its total cost, or cannot name the exam it prepares you for.
What to ask before enrolling
- Which certification exam does the program prepare me for?
- What is the total cost, and does it include books, membership and the exam?
- Is there an externship or practicum, and how many hours?
- What share of students pass the exam on the first try?
- How many graduates work as coders within a year?
- Can I study online and at my own pace around my shifts?
- Does the program accept federal aid or WIOA funding?

Frequently Asked Questions About Becoming a Medical Coder
Can a CNA become a medical coder?
Yes. No coding program requires a CNA, and none we found gives credit for one, but your medical vocabulary and charting habits help. Most people finish a certificate in 4 to 12 months, often online, then pass a certification exam such as AAPC's CPC or AHIMA's CCA.
Is medical coding a good career move from CNA?
For CNAs who want to leave lifting and bedside care, often. Coders earn a median of $51,140, $8,880 more than CNAs, and BLS projects 8% job growth over the decade. The catches: the first coding job is hard to land, the first year may pay little more than CNA work, and remote work usually comes after a few years.
How long does it take to go from CNA to medical coder?
AAPC says most people finish the coursework and pass the CPC exam in 4 to 8 months. A college certificate or diploma takes about a year full time, longer part time. Then plan for a job search: employers often want coding experience.
Does CNA experience count toward medical coding?
It helps, but it is not coding experience. BLS says healthcare experience is enough for some positions, and you already know medical terms. But AAPC counts only work using the coding code sets (CPT, ICD-10-CM or HCPCS) toward removing the apprentice "A", and no program we found gives credit for a CNA.
Can I become a medical coder online?
Yes. Many programs are fully online, such as Northcentral Technical College and Madison College in Wisconsin, Santa Fe College in Florida and National University.
Is medical coding a remote job?
Often, but usually not at first. In AAPC's salary survey, 64.8% of respondents work fully remote, but they have a median of 13.7 years in the field. AAPC says many employers want 2 to 5 years of coding experience before a remote position, and many entry-level roles start onsite or hybrid.
How much do medical coders make?
BLS counts coders as medical records specialists, with a median of $51,140 a year ($24.59 an hour). The lowest-paid 10 percent earn under $37,000, the top 10 percent over $81,150. Hospitals pay more than physician offices.
What is the difference between medical billing and coding?
Coders read the medical record and turn diagnoses and procedures into standard codes. Billers use those codes to get the provider paid: claims, insurance rules and payments. AAPC notes that in small practices one person often does both.
Should I take the CPC or the CCA?
Both are entry points. The CPC (AAPC) has 100 questions in 4 hours, and without 2 years of coding experience you hold it as CPC-A, an apprentice. The CCA (AHIMA) needs a high school diploma, and 62% passed on the first try in AHIMA's latest figures. Check which one the coding jobs near you ask for.
What does CPC-A mean?
Apprentice. If you pass the CPC without two years of coding experience, AAPC adds an "A". You can remove it with two years of coding work, one year plus Practicode or an 80-hour coding course, Practicode plus an 80-hour course with no job, or AAPC's Job-Ready Program with a 160-hour externship.
Will AI replace medical coders?
BLS still projects 8% job growth over the decade, much faster than average, but it notes that AI tools that make coding more efficient may affect demand. Keeping your credentials current and learning the tools is the best hedge.
Can I keep working as a CNA while I study coding?
Yes, more easily than on most paths. Many programs are fully online, and some are self-paced, so you can study around your shifts. Our CNA jobs page lists openings near you, with a part-time filter.
Information accuracy: training requirements, costs and pay change. Check the details with the program and your state before you decide. If you spot a mistake, let us know.
