Before a single insurance payer will consider credentialing you, they need to verify who you are. Your license, your work history, your malpractice coverage, your education, your certifications. Collecting that documentation manually - individually, for each payer - used to be a months-long administrative nightmare. CAQH ProView exists to solve that problem. But only if you build your profile correctly the first time.
Most practitioners hear "fill out your CAQH" and treat it like a form. It isn't a form. It's the central record that major payers - Aetna, Cigna, UnitedHealthcare, Humana, and dozens of others - pull directly when they process your credentialing application. An error in your CAQH profile doesn't just affect one application. It creates a ripple that delays every payer in your stack simultaneously.
"CAQH isn't a form you fill out. It's the credentialing record that every major payer reads. One wrong field can delay your entire panel by 60 days."
This guide walks through every major section of a CAQH ProView setup, flags the fields that cause the most errors, and explains how the profile fits into the 90-day launch sequence.
What CAQH ProView Actually Is
CAQH - the Council for Affordable Quality Healthcare - operates ProView as a universal provider data repository. When you register, you create a single, centralized profile containing your professional and practice information. Participating health plans are authorized to access that profile whenever they're processing a credentialing or re-credentialing request.
As of 2026, more than 1,000 health plans and hospitals use CAQH ProView to streamline credentialing. For most commercial payer panels, submitting your CAQH ID along with a credentialing application is required - not optional. CAQH does not initiate credentialing on your behalf. It makes your documentation available so payers can complete their own verification process faster.
CAQH is free for providers to use. You create an account at proview.caqh.org and self-register. Once your profile is live and attested, participating payers can access it with your authorization.
What You Need Before You Start
Attempting to fill out CAQH without your documents assembled first is the single biggest time-waster in the credentialing process. Practitioners who start without their materials end up saving partial profiles, losing data, and making errors when they return to sections they left incomplete.
Gather everything below before you open the CAQH portal.
Documents to Assemble Before Starting CAQH
- NPI Type 1 (individual) - required. You cannot complete CAQH without it.
- NPI Type 2 (group/entity) - required if you are credentialing under your practice entity.
- State license number(s) with issue date, expiration date, and state issuing authority.
- DEA certificate (if applicable) with expiration date.
- Current malpractice insurance certificate - carrier name, policy number, coverage limits, and effective/expiration dates.
- Education records - medical school or graduate program name, graduation date, degree conferred.
- Residency, fellowship, or clinical training program details with completion dates.
- Board certification information with certifying body and expiration date.
- 10-year work history with no unexplained gaps.
- Social Security Number or Tax ID (EIN) for your practice entity.
Step-by-Step: Building Your CAQH Profile
Step 1: Create Your Account and Self-Register
Go to proview.caqh.org and select "Register as a Provider." You will be asked for your NPI Type 1, name, date of birth, and primary practice state. CAQH will search for an existing profile associated with your NPI - if a hospital or previous employer has initiated a profile on your behalf, you may be merging into an existing record rather than creating a new one. Review any pre-populated data carefully before proceeding.
Step 2: Personal and Professional Information
This section captures your legal name, contact information, gender, primary practice specialty, and taxonomy codes. Taxonomy codes are where most practitioners make their first error. Your taxonomy code must match the specialty you are credentialing for. PMHNPs use 363LP0808X. NPs in family practice use 363L00000X. Using the wrong taxonomy code will cause payer applications to flag your profile as mismatched, creating a verification delay you won't notice until 60 days into the process.
Step 3: License and Certification Information
Enter every active clinical license with its exact number, issuing state, issue date, and expiration date. If you hold licenses in multiple states, enter all of them. CAQH also captures DEA registrations, board certifications, and specialty certificates. For each certification, include the certifying body (e.g., ANCC for PMHNPs), certification number, issue date, and expiration date. Expired certifications should still be listed if they fall within the work history window - payers verify continuity.
Step 4: Education and Training
Enter your graduate or professional degree program, institution, and graduation date. If you completed a residency, internship, or fellowship, enter the training institution, specialty, and exact start and end dates. Date gaps are a red flag for payer credentialing reviewers. If you took time off between training and licensure, note it accurately - payers are less concerned about gaps than about unexplained gaps.
Step 5: Work History
CAQH requires a continuous 10-year work history. List each employer, role, start date, and end date. If you have been employed for fewer than 10 years since licensure, list your training programs and supervised hours in earlier positions. Do not leave gaps. If you were not employed between two positions, note it with a brief explanation. This is the section most practitioners underestimate - payers use work history to verify supervision, prescribing authority, and any gaps that might indicate sanctions or license investigations.
Step 6: Malpractice Insurance
Enter your current malpractice carrier, policy number, coverage dates, and per-occurrence and aggregate coverage limits. Most commercial payers require a minimum of $1 million per occurrence / $3 million aggregate. If your coverage does not meet payer minimums, your credentialing application will be placed on hold. Resolve coverage gaps before submitting CAQH - not after.
Step 7: Practice Location Information
Enter your primary practice location - the physical address where you will see patients. If you are building a telehealth-only practice, enter your registered business address (not your home address). Include phone, fax, and billing address. If you are credentialing under a group NPI, enter your NPI Type 2 here and link it to your practice entity information.
Common CAQH Errors That Delay Credentialing
The following errors represent the most frequently reported CAQH issues that practitioners encounter when submitting to payers. Each one can add 30–90 days to your credentialing timeline.
| Error | Section | Typical Delay | How to Fix |
|---|---|---|---|
| Wrong taxonomy code | Personal Info | 45–60 days | Verify your primary taxonomy at NUCC.org before entering |
| Work history gap (unexplained) | Work History | 30–45 days | Add explanation note or fill gap with training/supervised hours |
| Malpractice below payer minimums | Malpractice | Hold until corrected | Confirm payer-specific minimums before credentialing submission |
| Expired license not updated | Licensure | Immediate suspension | Set calendar reminders 90 days before each expiration |
| NPI Type 2 missing or mismatched | Practice Location | 30–60 days | Confirm NPI Type 2 is filed and matches your business entity name exactly |
| Attestation not completed | Attestation | Profile locked out | Attest quarterly - payers cannot access an expired/un-attested profile |
Quarterly Attestation: The Step Practitioners Forget
CAQH requires you to attest - electronically confirm - that your profile information is current and accurate every 120 days. If you do not attest within that window, your profile is marked inactive and payers lose access to your data. That means credentialing applications already in progress can stall, and re-credentialing cycles that depend on your CAQH record cannot proceed.
Set a recurring calendar reminder 30 days before each attestation deadline. The attestation itself takes less than five minutes - you review your data for accuracy and click confirm. The maintenance cost is minimal; the cost of missing it is not.
Where CAQH Fits in the 90-Day Launch Timeline
- Week 1–2: File business entity (LLC/PLLC) and apply for NPI Type 2.
- Week 3: Create CAQH ProView profile and begin populating all sections.
- Week 4: Complete CAQH profile, attest, and authorize payer access.
- Week 4–5: Submit credentialing applications to target payers with CAQH ID.
- Month 2–3: Credentialing clock runs while website and billing infrastructure are built.
- Month 3: Payer approvals arrive; practice opens for insured patients.
CAQH is not the bottleneck in your credentialing timeline - your preparation is. Practitioners who arrive at CAQH with complete documentation set up their profiles in a single session and submit to payers the same week. Practitioners who arrive unprepared spend weeks in partial states, making errors and losing time they cannot recover.
Complete your CAQH profile in one sitting, with every document in front of you, and attest immediately. That single two-hour session starts a 90-day credentialing clock that will determine whether you open your practice on schedule or two months late.
