When a new physician joins your practice or a specialist signs on with a hospital, the first question that often arises is: What is credentialing in medical billing, and why does it take so long?
Medical credentialing is more than just paperwork. It’s the backbone of trust in healthcare, a rigorous process that verifies a provider’s qualifications, experience, licensure, and ability to deliver care. But it’s also a key pillar of a smooth revenue cycle management strategy. If your provider isn’t properly credentialed with payers, claims will be denied, simple as that.
Let’s walk through the provider credentialing process, how it works, where it goes wrong, and what best practices your organization should follow.
What Is Credentialing in Healthcare?
At its core, credentialing is the process of validating that healthcare providers, from physicians and nurse practitioners to therapists and specialists, meet the standards required by hospitals, insurance plans, and regulatory bodies.
This includes verifying:
- Professional education and training
- Board certifications
- Licenses and DEA registration
- Work history
- Malpractice claims or disciplinary actions
- Hospital privileges
Credentialing is not a one-and-done process. It’s required upon hire and must be revalidated every 2-3 years, depending on payer or facility requirements. According to the Centers for Medicare & Medicaid Services (CMS), failure to keep credentials up-to-date is a leading cause of claim rejections, directly impacting reimbursements. You also need to keep yourself updated with HIPAA rules for medical billing.
Why Medical Credentialing Is Essential for Revenue Integrity
Many practices view credentialing as red tape, a necessary evil. But in truth, it’s a compliance-driven, revenue-protecting function.
If a provider isn’t properly credentialed:
- Claims will be denied
- Patients can’t be billed through insurance
- The practice may face penalties or clawbacks
- Payers may delay enrollment of the entire group
This means every delay or error in healthcare provider credentialing is a potential bottleneck for revenue flow.
According to a 2023 HFMA study, over 35% of denied claims stem from eligibility or credentialing-related issues, many of which could have been avoided with early intervention. So, if you are not aware of it, medical billing and coding services can easily handle this for you.
The Step-by-Step Medical Provider Credentialing Process
Understanding how to credential a provider is critical, especially for revenue cycle professionals overseeing onboarding. The process involves:
-
Gathering Core Documents
Start by collecting the provider’s license, board certification, malpractice insurance, CV, work history, references, and more.
-
Primary Source Verification (PSV)
Each qualification must be confirmed directly from the issuing body (e.g., medical school, state license board). This ensures no credentials are falsified.
-
Application Submission to Payers
Submit credentialing applications to all insurance carriers that the provider will work with. Each has its timeline, typically 60 to 120 days, but delays are common.
-
CAQH Enrollment
Most payers require a profile on the Council for Affordable Quality Healthcare (CAQH). Providers must attest and update their CAQH profile regularly.
-
Payer Approval and Enrollment
Once verified, the payer issues a participating provider number. Only then can claims be submitted on the provider’s behalf.
Common Revenue Pitfalls in Credentialing
Let’s clarify this with a realistic scenario.
A pain management clinic hires a new MD but delays credentialing with a significant commercial payer. They assume the MD can bill under a supervising physician temporarily. However, after 45 days of service, the clinic receives denials citing “non-credentialed provider” and loses $50,000 in revenue.
This isn’t rare. Such errors happen due to assumptions about billing rules, incomplete applications, or CAQH profiles left unauthenticated. The takeaway? Credentialing errors can create cascading losses in medical billing software workflows and disrupt the practice’s cash flow.
Best Practices for Streamlining Credentialing
For practices and billing teams, adopting these provider credentialing process best practices can significantly reduce delays and denials:
- Start early: Begin credentialing 90–120 days before a provider’s start date.
- Centralize credentialing tasks: Use a credentialing management platform integrated with your medical billing software for small businesses or large group practices.
- Maintain CAQH regularly: Payers will not process outdated or unauthenticated CAQH profiles.
- Track payer timelines: Keep a checklist of all participating payers and their approval cycles.
- Document thoroughly: Save every communication, submission, and approval in a central file accessible to billing and compliance teams.
How Technology Is Transforming Credentialing
Many medical billing software now offer credentialing modules or integrations that automate parts of the process, from tracking expirations to verifying licenses.
For example, systems like Kareo, AdvancedMD, or ModMed offer modules where you can view pending credentials, upload documents, or get alerts on renewals. Some platforms even interface with CAQH to automatically update profiles.
If you’re a healthcare provider, choosing the right medical billing software with credentialing support can give your team a competitive edge, especially when managing multiple providers or specialties.
Compliance Reminders You Shouldn’t Ignore
Credentialing isn’t just about avoiding payment delays; it’s a compliance obligation. Regulatory bodies like The Joint Commission and NCQA require healthcare organizations to have structured credentialing and privileging processes.
You must also:
- Ensure credentialing policies match CMS and payer guidelines
- Update credentials promptly when a provider changes states or roles
- Re-verify credentials before reappointments or audits
Neglecting this can trigger CMS audits or even loss of network participation, both costly mistakes.
