Why Is Insurance Credentialing Taking So Long? 8 Common Causes

Key Takeaways 

• Standard insurance credentialing runs 60 to 120 days per payer, though Medicaid and certain regional plans can take longer.  

• NCQA tightened its primary source verification window in July 2025. Accredited plans now have 120 days to complete PSV, and certified CVOs have just 90. That leaves payers less slack than before, which can ripple into provider-facing delays.  

• CAQH, now operating as DataSpring, powered by CAQH, remains the single most common source of stalled applications when a provider’s profile goes stale.  

• Payer backlogs and internal processing capacity account for a real share of delays that have nothing to do with the provider’s paperwork.  

• A provider who doesn’t respond to a payer’s request for more information within the stated deadline often loses their place in the review queue entirely.  

• Actively tracking an application, rather than waiting to hear back, is the single habit that separates a 60-day approval from a 150-day one. 

One of the most frustrating things for providers is when insurance credentialing takes longer than expected. There’s usually no clear reason for this. Provider-side backlogs, requests for original source proof, and daily paperwork mistakes contribute. This can turn a process meant to take 60 to 120 days into something that quietly slips into its fifth or sixth month.  

This book lists the eight main reasons credentialing takes longer than it should, along with what providers and businesses can do to speed things up. 

How Long Does Insurance Credentialing Usually Take? 

Most business payers say it takes 60 to 120 days to complete an application from start to finish. Medicare usually moves during the same window. Medicaid varies by state, and depending on demand and staffing, some state programs take longer than 120 days.  

That range assumes the application is error-free and complete. If you add even one of these problems, the timeline gets very long very quickly. One open question about the timeline can turn a 90-day estimate into 150 days.  

Times also change based on the type of application. It usually takes longer for a brand-new provider to join a payer’s network for the first time than for a current in-network provider to add service at a new location. This is because the payer has to do full primary source verification instead of just checking the information it already has on file. Because most payers need to be recredentialed every two to three years, the process moves faster than the first time someone signs up. The file is already there. The payer is just making sure it’s still correct; they’re not making it from scratch.  

It helps to know what a service can handle and what it can’t. Application completeness, document accuracy, and response speed to payer requests are on the service side. Payer staffing levels, processing times, and how quickly a residency program responds to a request for verification are not. Knowing which category a delay falls into changes what needs fixing and how much time and effort it takes. 

Why Is Insurance Credentialing Taking So Long? 

Most delays trace back to a small set of recurring problems on both the provider and customer sides. In the order that providers see them most often, these things slow down the process. 

Incomplete or Incorrect Applications 

Most of the time, this is still the most basic reason. A blank field, no signature, or an NPI number typed incorrectly. Payers usually won’t start their internal clock until all required fields are filled out correctly. This means that an incomplete submission doesn’t just slow things down; it also pushes back the start date. 

Missing Provider Documents 

Board certifications, malpractice history, copies of state licenses, and DEA registration. Each payer needs a slightly different set of documents, and if an application is missing even one thing, it is generally put on hold until the missing item is found and completed. Some payers will not tell a provider what’s missing for weeks, which adds a full cycle to the schedule without being noticed. 

CAQH Information Not Updated 

Even though it changed its name to DataSpring, powered by CAQH, in June 2026, CAQH is still the shared data source that most payers use. Since existing logins, profiles, and papers weren’t affected by the rebrand, the name change isn’t the issue. An old profile is. If a liability carrier is out of date, a profile hasn’t been verified in 120 days, or the practice address hasn’t been updated, it will show up on all related payment applications, not just one. 

Payer Verification Delays 

Sometimes the wait time has nothing to do with the service. Payers check qualifications directly with medical schools, state boards, and the NPDB, and those groups respond on their own timelines. If a residency program’s records office takes too long to respond, an otherwise complete file can be held up for weeks. Often, the only thing a provider can do is follow up and wait. 

Errors in Provider Information 

The CAQH profile and the payment application may have mismatched dates, different names on two forms, and an address that doesn’t match. A payer’s review team will see these differences as red flags, even if they’re just honest mistakes. Fixing them usually means asking for more paperwork. 

Delays in Primary Source Verification 

The new NCQA guidelines for 2025 say that approved organizations have 120 days to finish PSV and qualified CVOs have 90. That’s a lot shorter than the 180-day window that used to be in place. That should make payers move faster, right? In real life, it also means less room for mistakes, so a provider-side mistake that used to cost two weeks can now take up a larger portion of the total available window. 

Payer Backlogs and Processing Times 

Credentialing departments handle a set volume of applications with a fixed number of staff, and that capacity doesn’t always scale with demand. A payer processing a surge of new applications, whether from seasonal hiring patterns or a network expansion, can genuinely be backed up regardless of how clean any individual application is. This is the one cause a provider usually can’t fix directly, only work around through active follow-up. 

Failure to Respond to Additional Requests 

Payers often send back a form that’s missing something or ask a question, and they almost always include a due date. The app doesn’t just pause if you miss it. Often, it goes back to the beginning of the review queue, erasing weeks of work. This is one of the most avoidable reasons for delay on this list, and it also costs a lot when it does happen. 

What to Do When Insurance Credentialing Is Delayed 

First, make sure your CAQH or DataSpring record is up to date and fully verified. A surprising number of stuck applications can be fixed with that one check. After that, contact the payer directly instead of waiting for an update. Ask the provider exactly what stage the application is in and whether anything else needs to be done.  

If the payer says there is a backlog but doesn’t say what the problem is, ask for an estimated date when the problem will be fixed and get it in writing or by email if you can. That record matters if the wait goes on much longer than the payer said and you need to bring it to their attention.  

When a provider is working on several client applications at the same time, a shared tracker that tracks due dates, follow-up dates, and unfinished tasks keeps one application from getting lost while the provider focuses on another.  

Also, check whether the delay is tied to a specific NCQA date. Right now, accredited plans have 120 days to work within the PSV window, and certified CVOs have 90 days. If a payer is close to its internal deadline, it may move faster when pushed, because the file needs to clear before its compliance clock runs out. A clear question about where an app is in relation to the window can get people to move in ways that a general state question wouldn’t.  

Lastly, let the person in charge of billing or the practice’s revenue cycle know as soon as you know there will be a delay. If a provider hasn’t been approved yet, the payer can’t pay them. Finding out after claims have been sent adds to the delay because it’s harder to fix the problem. 

How Providers Can Track Credentialing Progress 

Most payers have a site or a specific person to contact to check your claim status. If you use it regularly, usually once every one to two weeks, you can find problems early and fix them. If you wait for a payer to contact you, you might not find out about a missing document until three months have passed instead of three weeks.  

Instead of letting each staff member follow up on their own, a practice that handles insurance credentialing for multiple doctors is better off keeping everything in one place. When five providers work with different payers at different stages, informal tracking can easily fall apart. That’s when an application usually slips past its due date without anyone noticing until a claim is denied. The same level of care is needed to maintain CAQH credentials, since that profile is used in almost all of a provider’s future client applications.  

If a practice doesn’t have the resources to keep up with this level of detail, working with a partner that handles medical credentialing services and ongoing credentialing maintenance removes the guesswork about where an application stands. Because credentialing delays directly lead to reimbursement delays, it’s a good idea to connect that tracking to the team in charge of medical billing services so no one bills for a provider who isn’t fully enrolled yet. 

Frequently Asked Questions 

Why is my insurance credentialing taking longer than 120 days? 

Usually an old CAQH profile, an unanswered payer request, or a payer-side wait that has nothing to do with the quality of your application. 

Does CAQH becoming DataSpring affect credentialing speed? 

No. Only the name was changed in June 2026. We made no changes to the process; we migrated profiles, logins, and documents. 

Can I speed up insurance credentialing myself? 

Yes, to a point. You can avoid most common delays by keeping your CAQH profile up to date and replying quickly to payment requests. 

What’s the average insurance credentialing timeline in 2026? 

Most commercial payers take between 60 and 120 days. The Medicaid process can take longer and varies more by state. 

Should I follow up with a payer if I haven’t heard back? 

Yes. When you check in every one to two weeks, you find problems early instead of after months of waiting. 

Final Thoughts 

Often, insurance credentialing takes so long because of avoidable paperwork issues and payer issues the provider can’t fully control. You can fix the paperwork part: keep CAQH up to date, respond quickly to requests, and track every application yourself instead of waiting for a payer to contact you first.  

The other half just needs patience and persistence. When the wait isn’t the provider’s fault, you can use tools like tracking every conversation, following up on a set schedule, and reporting when a plan goes well past what was promised. It’s better to stay involved in the process than to just submit an application and hope for the best.
