Medical billing and coding careers can offer rewarding healthcare employment without spending the time and money on a medical or nursing degree. These professionals handle payments for healthcare providers, insurance companies, and patients. The need for medical billers and coders has increased with the rise in healthcare services.

Unique medical codes tell what the provider charges for services. Coders update medical records and claims with the right codes that describe patients' treatments and services.

Medical billers use these codes to create and submit claims to patients, insurance companies, and other payers.

This guide explores how to enter a career in medical billing and coding, including education requirements, certification pathways, and salary prospects.

What Is a Medical Biller?

While often one person does medical billing and coding, they are two jobs with different skill sets. Medical billers and coders do not provide patient care, but billers are more likely to work with patients. Billers must have good communication skills to discuss medical charges with patients, healthcare providers, and insurance carriers.

A medical biller uses special software to input medical codes and file claims with insurance companies or government agencies such as Medicare. The biller also submits a statement to the patient for any amount not covered by insurance. A medical biller may also:

  • Verify insurance coverage, pre-authorizations, and referrals
  • Correct statements and payments
  • Set up payment plans and collect on past due accounts
  • Appeal denied insurance claims
  • Be knowledgeable in HMO/PPO, Medicare, and Medicaid coverage

The U.S. Bureau of Labor Statistics (BLS) projects these healthcare professionals to grow by 9% between 2020 and 2030. The expected increase reflects the growing demand for healthcare by older adults and the expansion of insurance coverage among all age groups.

According to the American Association of Professional Coders (AAPC), a medical biller earns an average annual salary of $61,000, but earnings vary with setting, education level, certifications, and experience.

What Is a Medical Coder?

Medical coders assign codes to medical terms. These terms can refer to treatments, procedures, equipment, and services. Medical coders enter these codes into billing systems. With these codes, healthcare providers can receive correct payments through insurance or directly from patients.

Medical coders help keep billing and payments accurate and in line with regulations. Although coders usually work independently, they must communicate well with medical billers, physicians and nurses, and administrative staff.

Because medical coders work in many different healthcare settings, their day-to-day tasks may vary. However, common responsibilities include:

  • Analyzing patient records and clinical reports
  • Researching reimbursement and payment information
  • Translating medical information into codes for billing
  • Maintaining federal and state compliance
  • Performing audits for accuracy

Like medical billers, coders can expect an expanding job market through the end of the decade. AAPC reports that coders make an average yearly salary of $54,890, but they can earn much more with certifications. Earnings also vary by specializations, educational level, and experience.

    Associate-level graduates can find career opportunities in insurance companies, government, and healthcare providers. Students often transfer their associate degree credits to bachelor's programs.

  • Pass certification examinations.

    Healthcare employers generally prefer billers and coders who have earned professional certifications. These certifications ensure mastery of complex billing and government-mandated coding requirements.

    Certification can lead to more job opportunities and higher salaries.

  • Find employment.

    Many schools that offer medical billing and coding training offer career services. The career office can help learners prepare resumes, practice interview skills, and find job openings.

    Job candidates should include any internships and relevant work experience in their applications. Individuals can read AAPC's information on the cities and states that have the best job opportunities and highest salaries.

Medical Billing and Coding Certification

Diploma programs and associate degrees prepare students to enter this field and for professional certification exams. Most students pursue either the certified professional biller (CPB) or the certified professional coder (CPC) credentials.

While these are separate credentials, many programs offer dual certifications as CPBs and CPCs.

Working in Medical Billing and Coding

According to the BLS, employment for medical records and health information specialists will increase by a slightly faster-than-average rate of 9% from 2020-2030. Most jobs will be in these settings:

Hospitals (State, Local, and Private)

Hospitals are the major employer of medical records and health information specialists, hiring 37% of all workers in this category. While specific duties depend on the hospital size, medical billers and coders help manage revenue cycles. With accurate and up-to-date revenue data, hospitals can receive insurance reimbursements and payments from patients on schedule.

Doctors' offices need reliable medical coding and billing services. Larger clinics may offer higher salaries, but smaller offices might provide a less stressful environment with lower caseloads. Doctors' offices, especially smaller practices, often hire individuals who perform both billing and coding roles.

Administrative and Support Services

Many healthcare providers, government agencies, and insurance carriers rely on medical billers and coders in administrative and support roles. They design and carry out procedures that can boost efficiency and profitability.

Large healthcare facilities hire IT specialists and consultants to streamline coding and billing work. In smaller settings, administrative assistants with coding and billing expertise handle patient questions and process claims.

At insurance agencies, these professionals verify claims and work with patients to gather information and explain benefits.

Professional, Scientific, and Technical Services

This category includes colleges, law offices, insurance agencies, and IT companies. Colleges and technology schools hire experienced medical coders to train the next generation. Law offices hire coding and billing specialists to investigate fraud claims.

As the use of electronic health records becomes more prevalent, IT departments will hire more medical billing and coding experts to create, improve, and modify coding and billing systems.

Government agencies hire medical billers and coders to work on research projects. In these settings, they collect and analyze medical data for population health studies and healthcare policy reform.

Management of Companies and Enterprises
