Credentialing isn’t the most glamorous part of healthcare—but it is one of the most essential. Without proper enrollment, a provider won’t get paid. This is where CAQH (Council for Affordable Quality Healthcare) steps in, revolutionizing how provider data is collected, stored, and shared with payers.
For medical billers, practice managers, and independent providers, understanding CAQH in medical billing is non-negotiable. It’s not just a formality—it’s the foundation for timely reimbursements, network participation, and administrative compliance.
What is CAQH in Medical Billing, Really?
CAQH is a non-profit alliance of health plans and trade associations formed to streamline healthcare administration. Its ProView platform serves as a centralized database for provider credentialing data. But more than just a database, CAQH is a compliance and billing enabler.
Credentialing is the process of verifying a provider’s qualifications—licenses, education, liability coverage, and work history—before they’re allowed to treat patients under insurance contracts. Without CAQH, this would have to be done separately for every insurance payer.
CAQH ProView eliminates that duplication. Once a provider uploads and attests to their information in CAQH, they can authorize multiple payers to access that data instantly.
How Does CAQH Work in the Medical Billing Workflow?
Credentialing affects billing upstream in the revenue cycle. If credentialing is incorrect or incomplete, claims are denied, reimbursements are delayed, and patient scheduling becomes restricted.
Here’s how CAQH ties into that process:
Credentialing Flow:
- Provider joins practice or opens solo clinic
- Billers request a CAQH ID for new provider
- Provider profile is completed in CAQH ProView
- All payers are authorized to access CAQH
- Reattestation is done every 120 days
- Payers verify credentials before network enrollment
- Billers begin claim submission
Delay at Step 3 or Step 5? Claims submitted for a non-credentialed provider will likely be rejected or put on hold by insurance payers.
What Documentation is Required for CAQH?
Setting up a CAQH ProView profile is a detailed task. Medical billers should ensure nothing is skipped—incomplete profiles are a major bottleneck.
Required Information:
- NPI (National Provider Identifier)
- State License(s) for all states of practice
- DEA & CDS Certificates (if applicable)
- Medical Education History (with dates and locations)
- Specialty Board Certifications
- Work History (minimum past 5 years, no time gaps)
- Malpractice Insurance (COI)
- Practice Location(s), Billing Address
- IRS Form W-9
- Hospital Privileges
- Sanctions or Disciplinary Actions (must be disclosed)
Providers must digitally sign the attestation once the profile is complete.
Understanding the Reattestation Requirement
Every 120 days, CAQH requires providers to reattest—confirming all information is still accurate.
📌 Pro Tip for Billers:
Use automated reminders or credentialing software to track attestation windows. Missed reattestations can cause payers to suspend network access.
A missed attestation doesn’t just hurt compliance—it halts cash flow. Some practices lose tens of thousands per month due to lapses in credentialing status.
Best Practices for Maintaining CAQH Profiles
Maintaining a CAQH profile isn’t “set it and forget it.” It’s a living document that reflects real-time changes in a provider’s practice.
Best Practices:
- Update immediately after license renewals or address changes
- Ensure malpractice policy remains active
- Double-check expiration dates on uploaded documents
- Add new specialties, locations, or hospital privileges
- Track payer authorizations—some must be renewed
For large practices, a dedicated credentialing coordinator is often needed to maintain multiple profiles.
CAQH vs Manual Credentialing: Real-World Comparison
Let’s say a provider is joining 8 insurance networks. Here’s what credentialing looks like with and without CAQH:
| Task | Manual Method | CAQH Method |
|---|---|---|
| Fill out forms | 8 different forms | 1 centralized profile |
| Document uploads | Repeated per payer | Uploaded once |
| Errors/duplication | High risk | Significantly reduced |
| Time spent | 2–4 hours per payer | 1–2 hours total |
| Authorization | Case-by-case | Global with a click |
| Maintenance | Reapply with changes | Just reattest |
Without CAQH, credentialing takes weeks. With CAQH, it’s a few hours. That difference could mean thousands in lost revenue if the provider can’t see patients during that time.
CAQH vs PECOS (for Medicare Providers)
Many providers confuse CAQH and PECOS, but they are not the same:
| Feature | CAQH | PECOS |
|---|---|---|
| Ownership | Private non-profit | Federal (CMS) |
| Focus | Commercial plans | Medicare enrollment |
| Data Entry | Single profile | Separate for each provider |
| Automation | Credentialing data hub | No auto-sharing |
| Requirement | Most commercial payers | Mandatory for Medicare billing |
Bottom Line:
If you bill both Medicare and private insurance, you need to maintain both PECOS and CAQH profiles.

Common CAQH Mistakes That Delay Billing
| Mistake | Impact | Fix |
|---|---|---|
| Incomplete education history | Application rejected | Add all training with full dates |
| Missed reattestation | Payer deactivates profile | Set calendar alerts every 90 days |
| Licenses not updated | Denials on new claims | Upload renewed license immediately |
| Payers not authorized | Delays in credentialing | Reauthorize in CAQH dashboard |
| Duplicate accounts | Confusion & delay | Merge or delete old profiles via CAQH support |
Actionable Takeaways
- Start CAQH early—don’t wait for claims to be denied.
- Track expiration dates for licenses and malpractice insurance.
- Perform internal audits of profiles every quarter.
- Automate credentialing tasks if managing more than 3 providers.
- Educate providers about their role in reattestation and data accuracy.
