Introduction
Enrolling your providers with a payer? Are you Delegated or Non-Delegated? And what is the difference? Here's the easy way to remember the distinction: It all comes down to who's doing the credentialing and primary source verification. If credentialing and verification are handled by the payer, you're in a non-delegated model. If they're handled in-house by the medical group or through a credentials verification organization (CVO) — with payer approval — that's delegated credentialing. This one distinction shapes how quickly new providers can get in-network, how soon you can bill, how much control you have over data accuracy, and how efficiently your team can scale. Let's break it down. If you are already confused with all of the credentialing and enrollment terms being used — check out our article Demystifying Credentialing.
Payer managed credentialing
In a non-delegated credentialing model, the payer controls the entire process. When you submit a provider to join a network, that payer performs:
● Primary Source Verification (PSV) — verifying licenses, education, board certifications, and malpractice history directly with original sources.
● Credentialing Committee review — the payer's internal review process before approval.
● Network enrollment — once approved, the provider is added to the payer's systems. That means each payer performs its own full review, even if the provider has already been credentialed elsewhere. This model works fine for smaller practices or those contracting with only a few payers, but it comes with longer timelines, less visibility, and more administrative overhead. You don't control the overall timeline — the payer does. The process can take 90--120 days for the payer to credential your provider and for them to be fully enrolled and "in-network." Your team has to submit the same information to multiple payers, track credentialing statuses across several portals, and hope nothing falls through the cracks during the payer's credentialing process.
Delegated credentialing
In a delegated provider credentialing model, the payer gives the medical group or a CVO the authority to handle credentialing tasks on their behalf. A CVO (Credentials Verification Organization) is a third-party or internal unit that performs credentialing work for a provider network. They verify licenses, board certifications, education, malpractice coverage, and sanctions, and then issue credentialing decisions under defined standards. In a delegated model, the payer and the organization (medical group or CVO) sign a delegation agreement — a formal contract that spells out exactly:
● What credentialing and re-credentialing work the organization will perform.
● How often provider rosters and credentialing reports must be submitted.
● What performance metrics and audit standards the payer will use to monitor compliance. Essentially, the payer trusts the organization to credential providers correctly. The payer audits periodically to ensure compliance with NCQA, CMS, and their own internal standards. Payers don't delegate credentialing lightly. Before agreeing, they usually expect the organization or CVO to demonstrate six to twelve months of proven credentialing performance. Requirements often include:
Delegation requirements
1. Documented Policies and Procedures — Credentialing policies aligned with NCQA or CMS standards; a defined credentialing committee structure; and a written re-credentialing process scheduled every 2--3 years.
2. Primary Source Verification (PSV) Process — Organizations must verify licenses, education, board certifications, malpractice, and sanctions directly from the source; and maintain auditable documentation.
3. Data Accuracy and Audit Readiness — Clean provider data (CAQH, licenses, DEA, NPI, etc.) and systems prepared for on-site or virtual audits.
4. Technology and Data Controls — Secure credentialing systems with role-based access, audit logs, and reporting capabilities like rosters and PSV summaries.
5. Quality Metrics and Oversight — Payers retain audit rights, can revoke delegation, and expect timely responses to corrective actions. Some payers also look for NCQA or URAC certification, though it's not required if the payer performs its own audit.
Benefits of delegation
Delegated credentialing gives medical groups and MSOs a major speed advantage. When you control credentialing internally:
● You onboard new providers faster. ● You ensure more accurate provider data.
● You control credentialing timelines rather than waiting on payer schedules.
● You eliminate redundant work across payers.
● You quickly submit roster updates and re-credentialing files. For organizations managing hundreds or thousands of providers, delegation turns credentialing from a bottleneck into a scalable, repeatable workflow.
CAQH and verification
CAQH ProView remains a central repository for provider data. Delegated and non-delegated organizations both use it, but delegated entities treat CAQH as one of many data sources (licenses, NPPES, OIG, DEA, etc.). A complete CAQH profile is critical for non-delegated credentialing and enrollment. Meanwhile, Primary Source Verification (PSV) is required in both models. PSV validates that provider credentials are verified directly from the issuing source. In delegated models, PSV is the core of your credentialing program and the primary focus of payer audits.
Choosing the right arrangement
The difference between delegated and non-delegated credentialing comes down to one question: Who is doing the credentialing and verification work — you or the payer? If it's the payer, expect longer timelines and less control but fewer internal responsibilities. If it's you, expect faster onboarding and more control — but also higher compliance demands and auditing requirements. Both models have their place. But for large, multi-payer organizations, delegation is becoming the standard for speed, control, and data accuracy. With a modern credentialing platform like CredFlow AI, both delegated and non-delegated organizations can streamline payer follow-ups, automate roster ingestion, monitor network accuracy, and track credentialing requirements in real time.
