What Is the CPC Certification?
The CPC (Certified Professional Coder) certification is the gold standard credential for outpatient and physician-based medical coding. Administered by the AAPC — the largest professional association for medical coders worldwide with over 200,000 members — the CPC validates a coder's proficiency in CPT procedure coding, ICD-10-CM diagnosis coding, and HCPCS Level II supply and service coding.
Unlike generic healthcare credentials, the CPC focuses specifically on the technical skill of code assignment used in physician offices, outpatient clinics, and ambulatory surgery centers. Employers across hospitals, insurance companies, coding companies, and private practices widely recognize and often require the CPC for hiring and advancement. Candidates who pass the exam but have fewer than two years of professional coding experience receive an apprentice designation (CPC-A), which converts to a full CPC once the experience requirement is met.
The AAPC also offers specialty CPC credentials — including CPC-H (hospital outpatient), CPMA (auditing), and CPCO (compliance) — but the foundational CPC is the starting point for most coders entering the profession. Preparing with a CPC practice test is one of the most effective strategies for exam readiness.
The CPC exam consists of 150 questions total: 100 scored questions and 50 unscored apprentice questions embedded throughout the exam. Candidates have 5 hours and 40 minutes to complete the exam, making time management a critical skill to develop before test day.
The exam is open book — candidates may bring physical copies of the CPT manual, ICD-10-CM code book, and HCPCS Level II book into the testing room. Tabs and highlights are permitted in physical code books; electronic devices and digital code books are not allowed. This open-book format rewards candidates who know how to navigate the coding manuals quickly and efficiently rather than memorize every code.
Questions are multiple choice, with many requiring the candidate to assign one or more codes based on a brief clinical scenario. Operative report vignettes and complex multi-system cases appear throughout the exam. The passing score is 70% of the 100 scored questions, meaning candidates need at least 70 correct answers on the scored portion to pass. The 50 apprentice questions do not affect the pass/fail result but are used by AAPC for exam development purposes.
The CPC exam is available at AAPC-proctored testing sites and select Pearson VUE locations. Remote proctoring options are also available for candidates who prefer to test at home under live supervision.
CPC Eligibility and Application
One of the most accessible features of the CPC certification is that there are no prerequisites to sit for the exam. No prior coding experience, degree, or training program completion is required. Anyone who believes they are prepared may register and attempt the exam. This open eligibility policy makes the CPC attainable for career changers, recent graduates of medical coding programs, and healthcare professionals transitioning into coding roles.
To apply, candidates create an account on the AAPC website (aapc.com), complete the exam application, and pay the testing fee. AAPC membership ($170/year) is recommended because it reduces the exam fee by $100 and provides access to study resources, local chapter networking, and job boards. After payment, candidates schedule their exam at a convenient testing center or choose the remote proctoring option.
Candidates who pass the exam without having two years of professional coding experience are awarded the CPC-A (apprentice) designation. The CPC-A is a recognized credential, and many employers hire CPC-A holders for entry-level coding positions. Once the candidate documents two years of experience and submits verification to AAPC, the designation upgrades automatically to the full CPC at no additional cost.
For renewal, CPC holders must earn 36 continuing education units (CEUs) every two years. CEUs can be obtained through AAPC webinars, local chapter meetings, online courses, and approved coding conferences. Staying current with annual CPT and ICD-10-CM code updates is essential for maintaining both the credential and coding accuracy in practice.
Medical Coding Salary and Career Outlook
Earning the CPC certification measurably increases earning potential compared to uncertified coders. According to AAPC salary surveys and Bureau of Labor Statistics data, here is how compensation breaks down across experience levels:
- Entry-level medical coders (no certification): $34,000–$44,000 per year
- CPC-A (apprentice, 0–2 years): $38,000–$48,000 per year
- CPC (certified, 2–5 years experience): $45,000–$60,000 per year
- CPC with specialty credential or 5+ years: $55,000–$75,000 per year
- Remote senior coders / coding auditors: $65,000–$85,000+
The demand for certified professional coders continues to grow as healthcare organizations expand coding departments to keep pace with regulatory complexity, value-based care transitions, and increased telehealth billing requirements. The BLS projects medical records and health information specialist roles — which include coders — to grow 8% through 2032, faster than the average for all occupations.
Remote work is a significant advantage of the CPC credential. Many hospitals, health systems, and third-party coding companies hire remote coders, allowing CPC holders to work from home with competitive salaries and benefits. Specialty coding roles in areas such as cardiology, orthopedics, oncology, and risk adjustment command premium salaries and are accessible through additional AAPC specialty credentials after earning the foundational CPC.
