What is CAQH ProView and why does it matter?
CAQH ProView is a centralized online credentialing database used by more than 1,000 commercial health plans, Medicare Advantage plans, hospitals, and other healthcare organizations across the United States. When a healthcare provider applies for network participation with a commercial payer, that payer pulls the provider credentials directly from CAQH ProView rather than requiring the provider to complete a separate application for each organization. This centralization saves providers hundreds of hours of duplicated paperwork and gives payers a standardized data source for credentialing decisions.
The importance of CAQH ProView in the US healthcare credentialing ecosystem cannot be overstated. For commercial payer credentialing, CAQH is effectively mandatory. While a small number of payers use proprietary credentialing systems, the vast majority pull credentials from CAQH as their primary data source. An incomplete, outdated, or incorrectly configured CAQH profile creates downstream problems across every credentialing application that relies on it, making it the single most impactful element of commercial credentialing infrastructure.
CAQH ProView is distinct from PECOS, the Medicare enrollment system. CAQH handles commercial and managed care credentialing. PECOS handles Medicare Part B enrollment. Most providers need both systems active and current simultaneously, but they serve different payer segments and have different maintenance requirements.
Setting up your CAQH ProView profile from scratch
Creating a new CAQH ProView profile begins with registration at proview.caqh.org. You will need your NPI number, state medical license information, and basic practice details to begin the registration process. CAQH assigns a unique CAQH Provider ID upon registration, which becomes your permanent identifier in the system across all payer interactions.
The profile itself is organized into sections covering personal information, education and training, work history, hospital affiliations, professional references, malpractice insurance, state licenses, DEA registration, board certifications, practice locations, and disclosure questions about sanctions, disciplinary actions, and malpractice history. Each section must be completed accurately because payers use this information for primary source verification during the credentialing review process.
One of the most common mistakes providers make during initial setup is rushing through the profile to check the completion box without verifying accuracy in every section. CAQH reports your profile as complete based on whether all required fields have entries, not whether those entries are accurate. A profile can be marked complete while containing outdated addresses, expired malpractice certificates, or incorrect taxonomy codes that will trigger development letters from every payer that accesses it.
Document uploads are a critical part of profile setup. You must upload current copies of your state medical licenses, DEA registration certificates, board certification certificates, malpractice insurance certificate of insurance with claims history, and curriculum vitae. All uploaded documents must be current, meaning they must reflect the most recent renewal or issuance. Uploading an expired document is worse than uploading no document at all because it signals to payers that you may be practicing with expired credentials.
Payer authorization: controlling who accesses your credentials
CAQH ProView includes a payer authorization management feature that controls which organizations can access your profile data. By default, no payers have access to a new profile. You must explicitly authorize each payer you want to credential with to access your CAQH data. This is a critical step that many providers overlook, resulting in submitted credentialing applications that the payer cannot process because they cannot access the provider credentials in CAQH.
We recommend authorizing all payers you currently bill or plan to bill, plus any payers that commonly appear in your geographic market. Unauthorized payers who receive a credentialing application from you will send a development letter requesting CAQH access authorization, adding 2 to 4 weeks to your credentialing timeline while the authorization is configured and confirmed. Proactively authorizing payers eliminates this avoidable delay entirely.
The authorization list should also be reviewed periodically to remove payers you no longer work with or do not want to have access to your credential data. While CAQH data is not particularly sensitive beyond what is already public record, maintaining a clean authorization list is a compliance best practice that some practices prioritize.
The 120-day attestation requirement
CAQH requires providers to re-attest their profile every 120 days. Re-attestation is the formal confirmation that all information in your profile remains accurate and current. When the 120-day attestation deadline passes without re-attestation, CAQH automatically marks the profile as inactive. Payers who query an inactive profile receive an inactive status response, which halts any pending credentialing applications and may trigger re-credentialing reviews from payers where you are already enrolled.
The attestation process itself is straightforward, typically taking 15 to 30 minutes if no updates are needed. You log into CAQH ProView, review each section of your profile, make any necessary updates, and confirm that all information is current. If you have made changes since the last attestation, you update those sections before attesting. If nothing has changed, you simply confirm accuracy and submit the attestation.
The 120-day cycle is the single most common source of CAQH-related credentialing problems. Many providers set up their profile, authorize payers, and then forget about the quarterly attestation requirement until they receive a notice from a payer that their CAQH profile is inactive. By that point, pending applications may have been delayed or rejected, and re-credentialing reviews may have been triggered unnecessarily. Our CAQH management service includes automated attestation tracking and completion to prevent this entirely.
For group practices with multiple providers, attestation management becomes a significant recurring task. Each provider has a separate CAQH profile with a separate attestation cycle. A 10-provider group has 10 attestation deadlines to track on 10 different 120-day schedules. Consolidating CAQH management through a credentialing service eliminates the operational burden of tracking these individual deadlines.
Document expiration tracking and renewal management
Every document uploaded to CAQH ProView has an expiration date. State medical licenses expire on 1 to 3 year cycles depending on the state. DEA registrations expire every 3 years. Malpractice insurance certificates typically renew annually. Board certifications have their own renewal cycles. When any uploaded document expires, payers accessing the profile see an expired document, which triggers development letters from every payer simultaneously.
The cascade effect of a single expired document in CAQH is one of the most disruptive events in credentialing operations. If your malpractice certificate expires in CAQH on January 1 and you do not upload the renewal until February 15, every payer that accessed your profile during that 45-day window received an expired document. Each of those payers then sends a development letter requesting the current document, each with its own response deadline. A single expired document can generate 10 to 15 simultaneous development letter responses depending on how many payers are actively accessing your profile.
Proactive document management prevents this cascade entirely. The approach is to upload renewal documents before the existing document expires, not after. If your malpractice certificate expires March 1, the renewal should be uploaded to CAQH no later than February 15. If your state license expires June 30, the renewal should be uploaded by June 1. This buffer ensures payers never see an expired document regardless of when they access your profile.
Common CAQH mistakes and how to avoid them
The most frequent CAQH errors we encounter when onboarding new clients fall into predictable categories. Incomplete practice location information is the most common, with providers listing their main office but omitting secondary locations where they also render services. Each service location must be listed in CAQH for payers to properly credential you at that address.
Taxonomy code errors are the second most common issue. Your CAQH taxonomy code must match your NPI taxonomy code in NPPES and must be accepted by each payer for your specialty type. Taxonomy mismatches cause systematic claim denials even after credentialing approval because the billing taxonomy does not match the enrolled taxonomy. We verify taxonomy code consistency across CAQH, NPPES, and each target payer during our intake process.
Outdated work history is another frequent gap. CAQH requires a complete 10-year work history with no unexplained gaps. Providers who have moved between practices, completed training, or taken time off sometimes leave gaps in their work history that trigger payer inquiries and extend credentialing timelines. Accounting for every period in your work history, including training, leaves, and transitions, prevents these inquiries.
Finally, failure to disclose required information on the CAQH disclosure section is a serious issue. The disclosure section asks about malpractice claims history, license sanctions, hospital privilege restrictions, and other background items. Answering these questions honestly is essential because payers conduct independent background verification. A disclosure omission discovered during background checking can result in credentialing denial even when the underlying event would not have prevented approval if properly disclosed.
