If you’re looking for a career in healthcare, medical billing and coding may be the opportunity you’ve been seeking. Medical billing and coding is an essential part of the healthcare system that is used in every medical office, hospital, clinic, and healthcare facility. Campus now offers an Online Medical Billing and Coding program for students in Ohio. This program is designed to provide foundational training in medical billing and coding and prepare students for certification and entry-level opportunities in the field.
This program covers ICD-10-CM codes, CPT codes, procedural coding, claims processing, and more. Upon successful completion of the program, students may be eligible to sit for applicable medical billing and coding certification examinations and pursue entry-level opportunities in the field, subject to employer requirements and other factors.
What is Medical Billing and Coding?
Medical billers and coders encode the details of a patient visit into universally understood alphanumeric codes used by healthcare facilities, insurance companies, and government agencies. These codes are used to prepare and submit reimbursement claims to health insurance companies and government health plans, and also for updating electronic health records.
Billers and coders must select codes that most accurately describe the diagnoses, treatments, procedures, medical equipment, and other details of a patient visit. When claims are submitted for reimbursement, if the codes do not accurately match the services provided, the claims may be denied or adjusted.
Medical billing and coding are two distinct roles, but they can be done by the same person in a small organization, or by specialized people in a larger organization.
Medical coders encode all the details of a patient appointment into standardized codes used by healthcare organizations and insurance carriers across the entire country. The alphanumeric codes correspond to different diagnoses, procedures, treatments, prescriptions, and medical equipment. These codes are then used to create and submit reimbursement claims to insurance companies and also to update medical records. Accuracy is the top priority when matching codes to procedures and treatments, because insurance companies can deny claims if the codes don’t match the services provided.
Medical billers work with the codes provided by medical coders or healthcare providers and create, scrub, and submit claims. Great care is taken by the medical biller to check different fields, attach necessary documentation, and double check information before submitting each claim. Each insurance company has their own internal protocol for claims approval — the specificity, accuracy and completeness of each claim is analyzed before they are approved. Medical billers work with the insurance companies to fix any errors that are detected and troubleshoot claims before submission to ensure claims are approved in a timely manner.
Together, medical coders and medical billers make sure insurance reimbursement claims are filled out accurately, and medical offices are reimbursed promptly, maintaining the revenue cycle.
Why Become a Medical Coder and Biller?
Medical billing and coding functions are essential to healthcare operations and are performed by healthcare organizations either internally or through contracted service providers. Accurate billing and coding is necessary for encoding patient appointments and preparing reimbursement claims. Billers and coders are an essential part of the revenue cycle which helps medical offices run smoothly.
For an entry-level healthcare job, the pay differs from state to state, but can increase with experience. According to the American Association of Professional Coders (AAPC)[2], earning specialized medical coding certifications later in your career can help you earn more and increase your salary.
This job is different from many healthcare jobs, as many medical billers and coding positions may offer remote or hybrid work opportunities, depending on the employer and position. Many of these jobs became work-from-home in the early 2020s. If commuting is a challenge, medical billing and coding may provide opportunities to explore remote or hybrid work arrangements, depending on the employer needs and role.
If you enjoy analytical work, attention to detail, and problem-solving, medical billing and coding may be a career path worth exploring. The profession plays an important role in healthcare operations and may offer a variety of work environments and career opportunities depending on an individual’s skills, interests, and goals.

What Coding Standards Does a Medical Biller and Coder Need to Know?
Medical billing and coding is reliant on selecting the most specific, accurate codes for a given diagnosis, procedure, or treatment. You must be able to select the code that fits best, and when to select that code, in addition to any code modifiers. When you enroll in a medical billing and coding program, you’ll learn the intricacies of procedural coding and the coding standards that are used in every healthcare organization across the country. With hands-on experience, you will also learn more about how insurance companies evaluate the codes used in reimbursement claims, and what each insurer looks for in order to approve claims.
There are thousands of specific healthcare diagnoses, procedures, treatments, and corresponding codes. Most of these can be covered by three major coding sets, which are used in every healthcare facility in the United States.
ICD-10-CM: International Classification of Diseases, Tenth Revision, Clinical Modification. This is maintained by the World Health Organization (WHO).
CPT®: Current Procedural Terminology codes, these were created by the American Medical Association (AMA), currently maintained by the CPT Editorial Panel, appointed by the AMA.
HCPCS: Healthcare Common Procedure Coding System, created for use by government agencies such as Medicare and Medicaid.
