What about medical billing?

Medical coding and medical billing are separate jobs with unique roles and responsibilities.

Billers and coders work together to facilitate the healthcare revenue cycle. Coders interpret the care provided into the language a computer system can understand, and billers use these instructions to file insurance claims and post payments to accounts.

Develop enough experience in the field and you can potentially earn a larger role in both medical billing and coding—but many students pursue either billing or coding.

Frequently Asked Questions

Our goal is to best prepare you to become an excellent medical coder who is ready to excel right away in your first entry-level coding job.

While earning a degree/diploma is not always required to earn certain coding certifications, getting educated can help you qualify for more job openings, hit the ground running at full speed and position you best for career advancement.

Herzing University offers several undergraduate healthcare degree and diploma options that you may earn online, in addition to medical coding and billing:

Each program is positioned uniquely to build a foundation for you to pursue the type of job in healthcare you’re looking for—whether it’s directly caring for patients, focusing on day-to-day administrative tasks or leading the way in a managerial role.


Medical coding is a great career choice for detail-oriented people who work well on their own (a good option for introverts!) and seek a growing career field with opportunities for advancement.

Getting educated is your first step to finding the job you love. Become possible with Herzing University.


Herzing’s program features 100% online coursework for both the diploma and associate degree options.

The program does include a required research project or internship as part of the curriculum.

You can complete the research project online. If you choose the internship (pending eligibility in your state), you will be able to gain experience in a real working environment to best prepare you for your first entry-level job in medical coding.

Technology increasingly influences the evolution of the healthcare industry. Digital coding software called “encoders” can streamline the coding process and have provoked many to wonder about the future of medical coding.

Software can help to reduce the probability of human error but certainly does not replace what a human medical coder brings to the table: ability to decipher human documentation and the reasoning skills to accurately translate them into instructions for billing.

According to the 2019 projection from the Bureau of Labor Statistics, employment for medical records and health information technicians (including medical coders) is expected to increase 11% from 2018-2028, much faster than the average U.S. occupation.

Inpatient coding refers to a diagnosis report for patients who require hospitalization and must be admitted for an extended stay. Inpatient coding uses Internal Classification of Diseases, Tenth Revision (ICD-10) coding systems.

Outpatient coding refers to reports outlining services for patients who aren’t required to be hospitalized, typically those who are released within 24 hours. Outpatient coding uses Current Procedural Terminology (CPT) coding systems.

Inpatient and outpatient coding also deal with unique payment and reimbursement systems you will need to be familiar with.

You may learn inpatient and/or outpatient coding depending on whether you choose the associate degree or diploma path.

According to 2019 data from the Bureau of Labor Statistics (BLS), medical records and health information technicians (including medical coders) earn an average salary of $46,590 per year ($22.40 per hour).*

An affordable, career-focused education is within your reach. You may consider many different options for financial aid, including grants, scholarships, loans or student employment.

Medical coders translate the care provided to a patient into codes a computer system can understand. Coders categorize both diagnoses and procedures performed to convert a story of medical treatment into concise codes used for determining the cost of care.

Coders must work closely with physicians, billers and other healthcare personnel to ensure costs are distributed appropriately and claims are filed correctly. Accurate coding helps the business of healthcare run much more smoothly.

I love my instructors and the staff at the Herzing University. Their help and encouragement is what helped me achieve my degree. At the age of 54, who knew that I had this kind of potential? Herzing did, my family and friends did, and finally I did after I saw what I could do. Herzing is the best, and I am possible!
