CPCS Certification Guide (2026)
Unlike some healthcare fields with several competing certifications, credentialing has one clear standard: CPCS. Here's what it is and how to earn it.
What is the CPCS certification?
The Certified Provider Credentialing Specialist (CPCS) is issued by NAMSS (National Association Medical Staff Services) and is the main professional credential for healthcare credentialing professionals. NAMSS notes that its certifications are the only NCCA-accredited credentials for the medical services profession. The CPCS is held by specialists working in hospitals, health plans, medical groups, and credentialing verification organizations nationwide.
Eligibility requirements
- Currently employed or contracted in the medical services profession for at least 12 consecutive months within the last 24 months
- A total of 3 years of experience in the medical services profession within the last 5 years
- A completed application and paid exam fee
Provider enrollment specialists are not eligible for the CPCS. NAMSS offers a separate credential, the CPES, for that role.
How to earn your CPCS
- Meet eligibility - confirm you have the required medical services experience (our guide on how to become a credentialing specialist covers building it)
- Apply through NAMSS - submit your application by the deadline for one of NAMSS's three testing periods each year (spring, summer, or fall)
- Study the content areas - credentialing and privileging, primary source verification, compliance with standards, and medical staff services operations
- Pass the exam - 150 multiple-choice questions in three hours, requiring a scaled score of at least 400
Why it's worth earning
Beyond the professional credibility, NAMSS reports that more than a quarter of current certificants received a salary increase as a result of earning it. NAMSS also says certification signals to supervisors and accreditation surveyors that you're an expert in the field.
What's next after CPCS?
NAMSS also offers the CPMSM (Certified Professional in Medical Services Management), a more advanced credential aimed at medical services managers overseeing credentialing departments rather than individual specialists.
