How CAQH ProView credentialing works
CAQH ProView is a free centralized repository where providers maintain their credentialing data once and authorize payers to access it. Providers attest to data accuracy every 120 days. Payers pull data on enrollment and re-credentialing (every 36 months for most plans). Required data includes practice information, education and training, hospital privileges, malpractice insurance, work history, professional licenses, DEA, and disclosure questions. Incomplete profiles, missed attestations, and unauthorized payer access are the three most common causes of credentialing delays.
- Free centralized credentialing repository
- 120-day attestation cycle required

CAQH ProView: The Provider Credentialing Repository, Explained
By MedPrecision Operations Team · Published
CAQH ProView is the centralized credentialing repository used by most U.S. commercial health plans and many Medicaid managed care organizations to collect provider credentialing data. Run by the Council for Affordable Quality Healthcare, ProView is free for providers and lets payers access a single canonical credentialing record rather than collecting the same information separately. Understanding how ProView works — and the specific failure points that cause credentialing delays — is what separates a smooth payer enrollment from a six-month backlog.
What CAQH ProView Is
CAQH ProView (Council for Affordable Quality Healthcare Provider Data Exchange) is the U.S. healthcare industry's centralized credentialing data repository. CAQH is a non-profit alliance of health plans, providers, and trade associations. ProView lets a provider maintain credentialing data once in a single record and grant access to participating payers, replacing the historical practice of completing duplicate credentialing applications for each payer. The service is free for providers. Most major commercial health plans (UnitedHealthcare, Aetna, Cigna, Anthem, Humana, BCBS plans, and most regional commercial payers) use CAQH for primary credentialing data collection. Many Medicaid managed care organizations also accept CAQH data, though some state Medicaid fee-for-service programs maintain their own enrollment portals separately.
The Required Data Sections
A complete CAQH profile contains data across roughly 20 sections. Personal Information (legal name, NPI, DEA, SSN). Education and Training (medical school, residency, fellowship with dates and program names). Specialties and Board Certifications (with certifying board, certificate number, expiration). Practice Locations (each address where the provider sees patients, including office hours, languages, accessibility). Hospital Affiliations (current and prior privileges with status). Work History (continuous from medical school graduation, with explanations for any gaps over 30 days). Professional References (typically three peer references). Malpractice Insurance (current carrier, policy number, limits, coverage dates, history of claims). Professional Liability Claims History (any settled or pending claims, judgments, or denials of coverage). Disclosure Questions (criminal history, license actions, hospital privilege actions, Medicare/Medicaid sanctions). Many sections require document uploads — current malpractice declarations page, DEA certificate, board certification documents, state license verification.
The 120-Day Attestation Cycle
CAQH requires providers to attest to data accuracy every 120 days. Attestation is a simple confirmation that the data on file remains current; it can be completed in 5 minutes if no data has changed. Missed attestations cause the profile to lapse into 'Reattestation Required' status, and any payer attempting to pull data during the lapse receives a flag indicating the profile is not current. Many payers will hold credentialing or re-credentialing decisions until attestation is complete. The CAQH system sends email reminders 30, 14, and 3 days before attestation is due. The most common cause of attestation lapse is the email reminders going to a former practice manager or to an outdated email address — when a practice changes administrative staff, updating the CAQH contact email is essential.
Authorizing Payer Access
By default, no payer can access a CAQH profile. Each payer must be specifically authorized by the provider through the ProView portal. Providers can authorize individual payers, all CAQH-participating payers (called global authorization), or any combination. When initiating credentialing with a new payer, the standard sequence is: provider completes or updates the CAQH profile, provider authorizes the new payer in ProView, payer pulls the data and begins credentialing review, payer requests any payer-specific items not in CAQH (typically a payer-specific application supplement, W-9, or specialty form). Practices new to a market should complete CAQH first and then authorize each target payer rather than waiting for each payer's request — this front-loads the data submission and shortens the credentialing timeline.
Why Credentialing Stalls in CAQH
Five specific failures account for most credentialing delays involving CAQH. First, incomplete profile — required sections marked partially completed, or required document uploads missing. The CAQH portal flags incomplete sections explicitly; an incomplete profile cannot be authorized for payer access. Second, missed attestation, leaving the profile in 'Reattestation Required' status during a payer's pull. Third, unauthorized payer access — the provider completed CAQH but didn't grant access to the specific payer being pursued. Fourth, work history gaps over 30 days without documented explanation — payers commonly hold credentialing pending explanation. Fifth, malpractice insurance lapse or change of carrier without prompt update in CAQH — payers will not credential a provider showing lapsed coverage on file.
Re-Credentialing Cycles
Most commercial payers re-credential providers every 36 months under NCQA accreditation standards (NCQA Credentialing and Recredentialing CR 1-7). The re-credentialing pull from CAQH occurs in advance of the cycle date and uses whatever data is currently on file. This makes the 120-day attestation cycle critical — a missed attestation in the months before re-credentialing can delay it by 30-60 days while the provider scrambles to re-attest and the payer reschedules the review. The re-credentialing review typically focuses on continued license validity, malpractice insurance currency, any new disclosure events (license actions, criminal charges, malpractice claims), and continued participation in the practice's payer panels. Providers who maintain CAQH consistently rarely have re-credentialing issues; providers with stale data routinely face 30-90 day re-credentialing delays.
What CAQH Doesn't Replace
CAQH ProView covers commercial credentialing for participating payers, but it does not replace several other enrollment requirements. Medicare enrollment is performed through PECOS (Provider Enrollment, Chain, and Ownership System) — a separate CMS portal with its own application process under Form CMS-855I (individuals), CMS-855B (organizations), or CMS-855R (reassignment of benefits). State Medicaid enrollment varies — some states accept CAQH for credentialing data but require a separate state Medicaid application; others maintain entirely separate enrollment portals. Hospital privileging is a separate process at each facility with its own application and committee review. Workers' compensation, no-fault auto, and Tricare each have their own enrollment processes. CAQH is the largest single time-saver for commercial credentialing but represents perhaps half of the total enrollment work for a multi-payer practice.

Get a Free Billing Audit arrow_forwardIs CAQH ProView free for providers?
Yes. CAQH ProView is free for providers — there is no charge to create or maintain a profile, attest, or authorize payer access. CAQH is funded by participating health plans, which pay for access to provider data and for the platform's ongoing maintenance. The free model is intentional — CAQH's mission is to reduce administrative burden across the healthcare credentialing system, and provider participation is the foundation. Practices should be cautious of third-party services that charge providers for CAQH-related work; the underlying CAQH service is always free, though credentialing services that include CAQH maintenance as part of broader enrollment work can be a legitimate value-add when performed by experienced credentialing specialists.
How often do I need to attest in CAQH?
CAQH requires attestation every 120 days. The system sends email reminders at 30, 14, and 3 days before attestation is due. Attestation is a simple confirmation that the data on file remains current and takes about 5 minutes if no information has changed. Missing the attestation deadline puts the profile in 'Reattestation Required' status, and any payer attempting to pull data during the lapse will see the flag and may delay credentialing or re-credentialing decisions until attestation is complete. The most common cause of missed attestation is the reminder emails being sent to a former practice manager or outdated email address. When administrative staff change, updating the CAQH primary contact email is one of the first transitions to handle.
Which payers use CAQH ProView?
Most major commercial health plans use CAQH ProView for primary credentialing data collection — UnitedHealthcare, Aetna, Cigna, Anthem, Humana, the Blue Cross Blue Shield plans, and most regional commercial payers. Many Medicaid managed care organizations also use CAQH, though state-by-state variation exists. CAQH does not replace Medicare enrollment (handled through PECOS), state Medicaid fee-for-service enrollment in states that maintain separate portals, hospital privileging, or specialty payers like workers' compensation and Tricare. As a rough guide, CAQH covers commercial credentialing for the majority of providers' payer panels but represents about half of the total enrollment work for a multi-payer practice. The CAQH website maintains a current list of participating organizations.
How long does CAQH credentialing take?
CAQH itself is fast — a complete profile can be set up in 4-8 hours of work spread over a few days, mostly because of the document gathering required. The longer timeline is the payer-side credentialing review that follows. After CAQH data is authorized for a specific payer, the payer's credentialing review typically takes 60-120 days under NCQA standards, during which the payer verifies licenses, board certifications, malpractice history, work history, and disclosure responses. Some payers complete review faster (45-60 days) when the CAQH profile is complete and clean; others take longer when the profile has gaps requiring follow-up. The total elapsed time from beginning CAQH setup to receiving an effective payer participation date is typically 90-180 days depending on the payer and the cleanliness of the profile.
What happens if my CAQH attestation lapses?
When a CAQH attestation lapses, the profile enters 'Reattestation Required' status. Existing authorizations to payers remain in place, but any payer pulling data during the lapse will see a status flag indicating the profile is not current. Payers handle the flag differently — some pause active credentialing or re-credentialing reviews, others continue with the most recent attested data and add the case back to the queue when attestation is complete. The practical impact is that a lapsed attestation during an active enrollment or re-credentialing process can add 30-60 days to the timeline. Re-attestation is straightforward (5 minutes in the portal) but the downstream payer queue can take days or weeks to re-engage. Setting calendar reminders independently of CAQH email notifications, especially around staff transitions, is the simplest preventive.
Do I need to update CAQH when I change practices?
Yes — practice information is one of the sections that requires updating in CAQH whenever there is a change. New practice address, phone, fax, EIN, billing entity, hospital affiliations, and supervising physician (for non-physician practitioners under collaborative practice agreements) all require updates. Beyond updating CAQH, the provider also needs to handle the payer-side notification — payers require their own change-of-information forms when a provider moves practices, and the effective date of participation at the new practice depends on payer-specific timelines. CAQH update alone is necessary but not sufficient; the parallel payer notifications must happen for billing under the new practice to be processed correctly. Failing to update both leads to a common pattern where claims under the new practice deny because the payer's records still show the provider at the old practice.
