Before a provider can see patients as part of a payer's network, the payer usually reviews who that provider is and whether their qualifications check out. Hospitals and other healthcare organizations run similar reviews of their own. For practices, credentialing comes up when hiring clinicians, joining payer networks, opening a practice, adding locations, and maintaining participation over time. The exact steps depend on the payer or organization, but the reasons behind them are consistent.
What does it mean for a provider to be credentialed?
Credentialing is a payer's or healthcare organization's review of a provider's qualifications and professional information. Many organizations confirm key items directly with the body that issued them, a step called primary source verification. Depending on the payer, the review can cover:
- Current, unrestricted professional licenses
- DEA or state controlled substance registration, where applicable
- Education and training, and board certification where the provider reports it
- Work history
- Malpractice coverage and malpractice claims history
- License restrictions, state sanctions, and Medicare and Medicaid sanctions or exclusions
A provider who has completed this review is often described as credentialed with that payer. The approval is specific to each payer or organization and does not carry over to others.
Why do healthcare providers need credentialing?
Payers and healthcare organizations need confidence in the providers they work with. In practice, credentialing matters for several reasons:
- Payer participation. Commercial health plans generally credential providers before admitting them to their networks. UnitedHealthcare, for example, begins its network process with credentialing.
- Verified qualifications. The review confirms that licenses, training, and professional history match what the provider reports.
- Accurate payer records. Approved provider details, such as specialties and practice locations, feed the information payers keep in their systems and provider listings.
- Ongoing participation. Payers periodically recredential the providers in their networks, so credentialing records need to stay current after the first approval.
When does a provider typically need credentialing?
Common situations include:
- A provider joins an existing practice and needs to be added to its payer networks
- A new practice is opening and wants payer participation in place before billing as in-network
- The practice decides to accept a new payer
- A practice location is added or changes
- Recredentialing comes due with a payer the provider already works with
Requirements differ by payer, so confirm what each payer needs for each provider and location. If you are opening a practice, our overview of new-practice billing setup covers related steps.
Credentialing and becoming in-network are not the same thing
Being credentialed is usually one step toward joining a network, not the whole process. Becoming in-network typically involves several steps, which can include:
- Credentialing: the payer reviews the provider's qualifications
- Contracting: the provider or group signs a participation agreement with the payer
- Enrollment and setup: the payer adds the provider to its systems, usually with an effective date
UnitedHealthcare, for example, describes credentialing first, then contracting, then setting up the provider's portal profile. Until each required step is complete and the payer confirms participation and an effective date, a credentialed provider may not yet be in-network with that payer. Some networks may also be closed or limited in certain areas.
Credentialing vs. payer enrollment
Credentialing asks whether a provider meets the payer's requirements. Payer enrollment is the administrative process of connecting the provider, and often the practice, to the payer's records so claims can be submitted under the right arrangement. Government programs rely heavily on enrollment: federal rules require providers to be enrolled in Medicare to receive payment for covered services (42 CFR 424.505), and that enrollment is generally handled through CMS's PECOS system. The two processes overlap, but finishing one does not complete the other.
Credentialing vs. hospital privileging
Hospital privileging is a separate process. A hospital's medical staff examines a provider's credentials and recommends whether to grant medical staff membership and privileges, which define the clinical services the provider may perform at that facility. Medicare's hospital conditions of participation (42 CFR 482.22) require this review. Hospital privileges do not make a provider credentialed or in-network with a payer, and payer credentialing does not grant hospital privileges.
Where CAQH fits
Many payers use CAQH's provider data system, now offered as DataSpring, powered by CAQH, to collect the information they need for credentialing. The provider completes the profile, keeps it current, re-attests it on schedule, and authorizes each payer to view it. CAQH does not approve credentialing or enroll providers; each payer makes its own decision. Our CAQH profile guide explains profiles and re-attestation in more detail.
What practices should prepare before credentialing starts
Payers set their own requirements, but having these ready usually saves time:
- Provider identifying information and NPI
- Current state licenses and, where applicable, DEA or state controlled substance registration
- Education, training, and board certification details
- Work history
- Malpractice coverage certificate and claims history
- Practice and group information, including each practice location
- A current, attested CAQH profile where the payer uses one
Our provider credentialing readiness checklist walks through these records in more detail.
What can delay provider credentialing?
- Incomplete applications or missing signatures
- Information that does not match across the application, CAQH profile, and other records
- An outdated or unattested CAQH profile
- Expired licenses, certificates, or coverage documents
- Incorrect practice location or contact details
- Slow responses to payer requests for more information
Each payer sets its own review process and timeline, so starting early and responding promptly are among the few factors a practice controls.
When credentialing support may help
Credentialing is detailed administrative work that grows with every provider, payer, and location. Practices often look for outside help when adding several providers, managing many payer applications at once, opening a new practice, or keeping up with recredentialing. All State RCM can coordinate credentialing and payer enrollment work within an agreed scope, while payers make their own decisions and set their own timelines.

Frequently asked questions
Why do providers need to be credentialed?
Payers and healthcare organizations credential providers to confirm their qualifications before the provider participates with them. For most practices, it is a required step toward joining payer networks.
Is credentialing required for every insurance payer?
Requirements vary. Commercial health plans generally credential providers before network participation, while Medicare relies on its own enrollment process. Check each payer's current requirements.
Is credentialing the same as payer enrollment?
No. Credentialing reviews a provider's qualifications, while payer enrollment connects the provider to the payer's records for billing. Many payers require both.
Does being credentialed mean a provider is in-network?
Not necessarily. Network participation can also require a signed participation agreement and the payer's confirmation of an effective date.
Does CAQH approve provider credentialing?
No. CAQH holds profile information that payers can view with the provider's authorization. Each payer makes its own credentialing decision.
When should a new practice start credentialing providers?
As early as practical, once provider and practice information is ready, because each payer sets its own processing time. Payers do not guarantee approval or a particular effective date.
