Medical coding continue to be in strong demand as the healthcare industry extends its historic growth. Now may be the perfect time to begin your career as a medical coder.

As the backbone of the healthcare system, medical coding and billing make modern healthcare possible by connecting service providers with insurers to ensure fast processing.

Medical coding classifies healthcare procedures and treatments in a way that both doctors and insurers understand.

Medical billing uses medical codes and standard processes to help ensure that healthcare providers get paid for their services and that claims go smoothly for patients.

Reasons to become a medical coder and biller

As the US healthcare industry continues its growth, the future for medical coding and billing looks bright.

Here are some of the top reasons to consider a career in medical coding and billing:

  • You’ll be working in the growing healthcare industry. With an aging population, increasing healthcare needs keep demand high for medical billing and coding.
  • You don't need to go to medical school. You can train to become a medical coder or biller online and at your own pace. The American Academy of Professional Coders offers online training and certification. In many cases, you can complete your training within 1-2 years.
  • Remote jobs for this career are increasingly popular. Because you're working with data, medical coding and billing work is a good fit for remote work. Often, you can enjoy a flexible schedule and work from the comfort of home.
  • You’ll find plenty of opportunities to move up the ladder. As you gain experience or earn new certifications, you'll find more opportunities for advancement. You can also expect higher average annual earnings as you gain experience.

When working in medical coding, you’ll convert medical services and procedures to the following groups of codes:

  • Diagnostic codes: Medical treatments begin with an exam and diagnosis. As a medical coder, you’ll translate the descriptions of diseases, illnesses, and injuries into their medical classifications.
  • Procedure codes: The various procedures used in healthcare also have medical codes. Procedure codes can refer to the actual procedures performed but can also refer to medical equipment or medications given to the patient.
  • Pharmaceutical codes: Each type of medication has a code as well. However, medical pharmaceutical codes can refer to a specific type of medicine or to an active ingredient.
  • Topographical codes: In medical coding, topographical codes (or topography codes) refer to a specific area of the body. These codes are helpful to both doctors and insurers because they specifically identify the area affected by illness or injury.

Medical codes use a universal coding system to classify illnesses or injuries as well as treatments. These codes can be used to track and understand illnesses but they're also an essential part of medical billing.

In most cases, healthcare is provided as part of a 3-party system which includes the doctor and patient, but which also includes the insurer.

Often, the insurer pays the lion's share of healthcare expenses and medical billing must follow a specific format.

Medical billing uses medical codes to create invoices that can be tracked and paid by the insurer. It's also common for patients to pay a portion of their medical expenses.

  • Front-end medical billing: Front-end billing refers to the portion of the bill for which the patient is responsible. Examples include copayments, deductibles, or procedures not covered by the insurer.
  • Back-end medical billing: Back-end billing refers to Insurance claims and amounts that should be paid by the insurer. Standardized forms are used depending on the type of treatment and coverage. For example, a medical biller might use form CMS-1450 to submit a claim under Medicare Part A. However, a CMS-1500 might be used to submit a claim under Medicare Part B.

What does a medical coder and biller do?

In some job environments, medical coders are distinct from medical billers. In other cases, daily tasks are split between the two roles. Depending on your role and certifications, you may spend part of your day coding and another part of your day billing.

Your daily duties can include the following tasks:

  • Analyze patient’s records, including diagnosis and treatment
  • Convert diagnosis and treatment descriptions to standardized medical codes
  • Use standardized medical codes to invoice patients and submit claims to insurers
  • Work closely with doctors and assistants to ensure the accuracy of coding
  • Submit claims to insurers and follow up on payments
  • Submit invoices to be paid by patients
  • Interact with patients regarding insurance and billing matters

Skills needed for a medical coding and billing career

Your training can give you the knowledge you’ll need to work in medical coding and billing. However, you’ll also need some key traits and basic skills.

  • You’ll benefit from basic computer knowledge. Much of your work centers on using a computer or a dedicated terminal and specialized software.
  • Discretion and integrity are also key. Because you'll be working with personal information for patients, discretion is a must. In fact, HIPAA protections that ensure medical privacy also govern the way medical billing must be submitted in claims.
  • You’ll also need thoroughness. Accuracy is key when coding and billing. Even small errors or omissions can create delays or denied claims.
  • Above all, you’ll need analytical thinking. Context can play a big role in medical billing and there may be multiple ways to bill a procedure. Your ability to analyze all the factors is key.
  • Knowledge of medical science and terminology is essential. A big part of your job is to translate medical jargon and records into standardized codes. You won’t need to perform any medical procedures yourself, but you'll need to understand the diagnosis and the treatment to properly code these items.
