Guide to Medical Coding Certification

To the general public, medical coding is one of the more mysterious aspects of healthcare. There are no prime-time TV dramas about the love lives of the medical coders as they sit behind their desks, assigning specified codes to different medical procedures to keep effective medical records and ensure that bills and payments are accurate.

But what it lacks in drama, the career makes up for stability and growth. According to the Bureau of Labor Statistics (BLS 2021), the number of positions for medical records and health information specialists—including medical coders—is expected to grow 9 percent nationally from 2020 to 2030. Medical coders are required in virtually every private practice, hospital, and clinic. After gaining some experience, many coders are even able to work from home, which adds to the appeal of this profession for many.

However, for someone with little to no experience, medical coding certification is a critical step to take. Certification can improve an applicant’s chance at landing a job and can come along with a higher salary. To become certified, medical coding professionals must demonstrate a thorough knowledge of one or more of the three code sets that are currently in use: Current Procedural Terminology (CPT), ICD-10-CM, and Healthcare Common Procedure Coding System (HCPCS) Level II.

Medical coding certification is available through a few different organizations. The right certification for any coder ultimately depends on a candidate’s experience and intended specialization.

What is Medical Coding Certification?

Although medical coding certification is not a legal requirement to find employment as a medical coder, professionals with certifications are more likely to be employed and earn a better salary than those who have not earned a certification. Certification demonstrates an important foundational knowledge of the three aforementioned key code sets, meaning that certified medical coders can be more efficient and by extension, offer more value to their employer.

There are several different certifications that prospective medical coders can choose to pursue, although three of the most common are the Certified Professional Coder (CPC), the Certified Coding Specialist (CCS), and the Certified Medical Coder (CMC), each of which is offered by a different organization. Coding work can vary greatly depending on the healthcare setting a coder chooses, so it is important that students seeking certification choose the one that matches their ultimate goals.

How to Become a Certified Professional Coder (CPC)

The Certified Professional Coder (CPC) certification may be an ideal path for those interested in working in an outpatient setting, such as a physician’s office or outpatient clinic. The CPC exam is the most popular medical coding certification exam in the field of medical coding.

Certifying Organization

The CPC certification is offered by the American Academy of Professional Coders (AAPC), which is the largest organization of its kind with more than 200,000 members.

Prerequisites for CPC Certification

Although not strictly required, the AAPC recommends that anyone taking the CPC exam have at least an associate’s degree from an accredited institution. Most people who choose to take the CPC exam also have existing experience in the field of medical coding.

It is important to note that successful completion of the CPC exam is not enough to qualify the examinee as a Certified Professional Coder. Those that choose to take the exam without first gaining professional experience in the field will earn a CPC-A certification, which stands for Certified Professional Coder-Apprentice. To become a full CPC, the coder must complete at least two years of professional experience and submit two letters of recommendation to the AAPC.

To qualify for the exam, applicants must be current members of the AAPC and pay an exam fee. Sitting for the CPC exam costs $399 ($325 AAPC Students).

Certifying CPC Exam Details

The CPC exam consists of 150 questions, divided into 12 distinct sections, including:

  1. Surgical procedures (60 questions)
  2. Evaluation and management (10 questions)
  3. Anesthesia (8 questions)
  4. Radiology (10 questions)
  5. Pathology and Laboratory (10 questions)
  6. Medicine (10 questions)
  7. Medical terminology (8 questions)
  8. Anatomy (8 questions)
  9. ICD-10, volumes 1 and 2 (10 questions)
  10. HCPCS Level II Codes (5 questions)
  11. Coding guidelines (6 questions)
  12. Compliance and regulation (5 questions)

An overall score of 70 percent is required to become certified. More than 80 percent of people who take the CPC exam pass on their first attempt.

Ongoing CPC Certification Requirements

Continuing education is required to remain certified. CPCs must complete at least 36 hours of approved Continuing Education Units (CEUs) every two years. CEUs may be earned by attending conferences, online courses, or other approved events.

How to Become a Certified Coding Specialist (CCS)

For those who want to jump-start or grow their career in medical coding at inpatient facilities, the Certified Coding Specialist (CCS) certification program is the most popular choice and is most comparable to the CPC.

Certifying Organization

The CCS is available through the American Health Information Management Association (AHIMA).

Prerequisites for CCS Certification

To sit for the CCS exam, a coder must have at least one of the following:

  • A diploma or degree from a medical coding training program
  • Two years of medical coding experience
  • An existing medical coding certification plus one year of medical coding experience

As with the CPC, examinees must be members of the AHIMA to sit for the exam. Member price is $299, while non-members pay $399.

Certifying CCS Exam Details

The CCS exam covers four main domains, including:

  1. Coding Knowledge and Skills
  2. Coding Documentation
  3. Provider Queries
  4. Regulatory Compliance

The Coding Knowledge and Skills domain comprises the largest portion of the exam at up to 51.9 percent of the questions. The pass rate for first-time testers in 2020 was 83 percent. The passing score for the CCS exam is 300.

Ongoing CCS Certification Requirements

Continuing education is required to remain certified. CCSs must complete at least 20 hours of approved Continuing Education Units (CEUs) every year. In addition, CCSs must complete an annual coding self-assessment.

How to Become a Certified Medical Coder (CMC)

The Certified Medical Coder (CMC) certification is less common than either the CPC or CCS certifications, but it’s increasingly recognized as a comparable certification. In fact, the CMC has an exam format that is thought to be more difficult than the other two exams (which are multiple-choice).

Certifying Organization

The CMC certification is offered by the Practice Management Institute (PMI).

Prerequisites for CMC Certification

Before completing the CPC exam, applicants should have at least one year of professional experience in medical coding. PMI offers an introductory course called Principles of Coding for inexperienced coders. Although PMI offers preparatory courses for the CMC exam, those courses are not a prerequisite for taking the CMC exam.

Certifying Exam Details – CMC

The most significant difference between the CMC exam and the CPC or CCS exam is that it is not offered in a multiple-choice format. Rather, examinees must assess coding scenarios and be able to fill in the blanks accurately. The CMC exam is also only offered in a live, proctored setting.

The CMC online preparatory course comprises 21 hours of high-level coding instruction and practice exercises led by a PMI-approved Instructor. Examinees must earn a minimum of 70 percent to become certified.

Ongoing CMC Certification Requirements

To maintain certification, CMCs must earn 12 CEUs annually and submit proof of completion to PMI.

Specialized Medical Coding Certifications – AAPC

The CPC, CCS, and CMC are among the most common certifications and can act as important entry-level certifications for medical coders who are newer to the profession.

However, in order to open more doors for career advancement and higher salaries, many medical coders choose to specialize even further. The AAPC and AHIMA offer more specialized certification exams for experienced coders.

Certified Outpatient Coder (COC)

The COC certification (formerly known as the CPC-H) is specifically for coders working in hospital settings. The COC exam and certification indicate a high level of competency in coding specific to hospital groups, ambulatory surgical centers, and hospital billing and coding departments.

Certified Inpatient Coder (CIC)

The CIC certification, as the name suggests, is targeted to those working or wishing to work in inpatient settings. According to AAPC, the CIC “validates expert-level knowledge and experience in abstracting information from the medical record for ICD-10-CM and ICD-10-PCS coding, and specialized payment knowledge in MS-DRGs and Inpatient Prospective Payment Systems (IPPS).”

Certified Professional Coder-Payer (CPC-P)

While medical coders have typically worked in healthcare provider settings, increasingly health insurance companies and other healthcare payers are employing their own coders.

The CPC-P certification is designed for those wanting to work on the payer side of the coding practice, demonstrating “proficiency and knowledge of coding guidelines and reimbursement methodologies for all types of services from the payer’s perspective.”

Certified Risk Adjustment Coder (CRC)

The CRC certification is specific to those coders working in the risk adjustment sector. CRC certification is awarded to those who pass an exam indicating knowledge of ICD-10-CM specific to risk adjustment models such as HCC, CDPS, and HHS Risk Adjustment.

Other AAPC Specialty Medical Coding Certifications

The AAPC also offers coding certifications in the following specialties:

  • Ambulatory Surgical Center (CASCC)
  • Anesthesia and Pain Management (CANPC)
  • Cardiology (CCC)
