Most people think of doctors and nurses when they consider careers in health care. However, there is a large group of professionals behind the scenes who help the system work, and two of the most important are medical billing and medical coding.
Many people consider medical billing and coding as a career option because they want to work in health care without going to medical school for many years. It is also a good option for those who like office work, as the professions involve routine and provide stability in a growing industry.
In this blog, I will discuss the workings of a medical biller and a medical coder, the differences between the two, available jobs, expected salaries, required skills, and the advantages and disadvantages of the profession. By the end, I hope to clarify the importance of medical billing and coding careers and help you determine if this profession suits your strengths, goals, and lifestyle.
Medical Billing vs. Coding
Even though medical billing and medical coding are often used together and professionals may sometimes wear both hats, these are actually different roles. Appreciating the difference will help you see how both fields operate side by side to assist healthcare providers, healthcare patients, and the healthcare insurer.
What Is Medical Billing?
Medical billing attends to the long tail of healthcare billing services. The link between providers of healthcare and the healthcare insurer is the medical biller. The biller ensures the bill is paid and services rendered are provided in a timely manner.
Here are the typical tasks performed by a medical biller:
- Claims preparation and submission: The biller takes the patient’s coded medical info post-care and prepares it as a claim for healthcare services rendered to the patient.
- Insurance provider communication: Billers verify claims that are pending and follow up to resolve any denials and rejections.
- Patient billing: When the patient’s insurance does not cover the services fully, the biller sends the patient an invoice and may set up a healthcare payment plan.
- Compliance: Billers are responsible for claims to meet the guidelines of federal compliance, insurance billing requirements, and healthcare laws.
To put it concisely, medical billing involves managing finances within the healthcare system, ensuring both the providers and the patients understand and accept the costs.
What is Medical Coding?
Coding, however, is the language of healthcare and involves translating patient records, including all the documentation, diagnosis, and treatment, into codes. These codes are universal and necessary for billing, insurance, healthcare analytics, and research purposes.
Here are some responsibilities of medical coders.
- Reviewing clinical documentation: Coders analyse and interpret doctors’ notes, lab reports, and discharge summaries.
- Assigning codes: Coders use the ICD-10 (International Classification of Diseases), CPT (Current Procedural Terminology), and HCPCS Level II and other coding manuals to provide a complete and detailed code for every diagnosis and procedure performed.
- Supporting accurate billing: Coders ensure that the assigned codes reflect the services the provider performed and determine payment and claim approvals from insurance providers.
- Ensuring accuracy and compliance: Coders are tasked with monitoring coding changes, compliance with other healthcare regulations, and accuracy of healthcare services documentation.
While billers manage finances and coders manage information, each is vital to the system’s smooth operation.
How They Work Together
Think of it this way: medical coding is a language, and medical billing is a conversation using that language.
Without accurate coding, billing would be impossible because insurers wouldn’t know what services were provided. Without billing, codes would be meaningless because providers wouldn’t receive payment. Together, these roles form the backbone of healthcare administration.
Imagine a patient scenario: A patient visits a general practitioner for a consultation and a blood test. After the appointment, the medical coder looks at the notes and codes them for both the consultation and the test. The biller then takes those codes and submits a claim to the patient’s insurance provider. After the claim is approved, the healthcare provider receives their payment, and the patient receives a bill for the remaining balance.
This is why coding and billing are viewed as two sides of the same coin – they are distinct, but their separation is impossible.
Medical Billing and Coding Jobs
One of the biggest draws for medical billing and coding is the job variety. As the healthcare industry continues to grow, so does the need for trained billing and coding professionals to ensure recorded information is accurate and payments are processed on time.
Job outlook for medical coders
The healthcare sector is growing quickly, both in the UK and the world, and so is the demand for medical billers and coders. This is due to advancements in technology, the increasing number of patients, and the growing number of older patients in the population. Research shows that the demand for health information management jobs, which include medical billing and coding, will continue to grow for the next ten years.
This demand is driven by the following:
- Increased need for medical documentation: More patients mean more documentation, more records to file, and more claims to bill.
- Compliance and regulation: With more regulations for billing, insurance, and healthcare documentation, the need for annotated and precise coding and billing is critical.
- The use of technology: The introduction of Electronic Health Records (EHRs) and automated systems for billing and coding has made the need for specialized staff more critical.
This means job security, which is a great advantage, especially if you want a job that is not likely to be automated.
Work environments for medical coders
The job of a medical biller and coder is not limited to one type of workplace. Below are the most common work environments you will encounter:
- Hospitals: Large healthcare facilities recruit whole teams of medical coders and billers for the management of extensive patient loads and medical procedures.
- Clinics and General Practice: In smaller practices, one or two billing and coding professionals may be employed.
- Insurance Providers: Some professionals work on the other side of the process by evaluating claims as well as making sure they are accurate.
- Speciality Practice: Every speciality in healthcare, from dentistry to physiotherapy, requires healthcare coders and billers.
- Remote Work: As digital health records become the norm, more healthcare coding and billing jobs can be done from home. This appeals to those prioritising flexible work arrangements.
The variety helps narrow down to a work environment of your choosing. If the high energy of a hospital isn’t for you, you can opt to work in a more tranquil environment of a private clinic.
