7 Credentialing Mistakes That Could Be Costing Your Practice—and How to Fix Them!

If you’re running a busy healthcare practice, you already know: credentialing isn’t just a formality. It’s the backbone of getting paid and staying compliant. But here’s the catch—credentialing isn’t just time-consuming; it’s high-stakes. A small mistake here and there can easily spiral into claim denials, delayed reimbursements, and frustrated providers who can’t see patients.

And the worst part? These mistakes are way more common than you might think.

At Practolytics, we work with over 1,400 providers and support practices in 31 states, handling over 5 million claims every year. That gives us a unique view into what really goes wrong with credentialing—and what to do about it. This blog is your deep dive into the 7 most common credentialing mistakes, how to fix them, and how to finally stop credentialing from slowing your clinic down.

Let’s start from the top.

One Mistake That Starts Everything Off Wrong: Waiting Too Long!!!

Let’s be honest—most practices don’t begin the healthcare credentialing process early enough. Maybe you just hired a new physician and they’re starting in two months. That sounds like enough time, right?

Unfortunately, no. Credentialing is slow by design. Whether it’s Medicare, Medicaid, or commercial payers, most applications take 90 to 180 days to process. And that’s assuming no hiccups along the way.

Starting late puts you in a bind. The provider is seeing patients, but your claims are either being denied or not being submitted at all. That means a billing backlog, compliance risks, and a frustrated team.

How Practolytics Helps: 

We encourage all clients to start credentialing 4–6 months before a provider’s start date. Our team integrates credentialing into your onboarding process, so no time is wasted, and everyone knows where things stand.

Mistake #2:The Silent Killer- Incomplete or Incorrect Applications

You’d be surprised how often applications are rejected because of the tiniest issues—a misspelled name, wrong NPI number, missing malpractice certificate, or an outdated license. And many payers don’t notify you immediately; instead, your application just sits in limbo.

This creates unnecessary delays, often requiring a complete resubmission.

Real-world stat: In a recent industry survey, 44% of payer delays were due to missing or incorrect documentation.

How Practolytics Helps: 

We use a combination of manual oversight and tech-enabled tools to validate every single document before submission. Our clients also get real-time status updates and checklists, so nothing slips through the cracks.

Mistake #3: Credentialing’s Sneaky Enemy- Document Expirations

Let’s say your provider was fully credentialed last year. Great! But now their DEA registration expired last month and you didn’t catch it. Suddenly, they’re flagged as non-compliant by payers. That means denied claims and a risk of being dropped from networks.

The worst part? This isn’t just about one document. Credentialing is full of expiration dates:

• DEA licenses
  
• State licenses
  
• Malpractice insurance
  
• Board certifications
  
• CAQH attestations
  

Miss one, and the whole revenue cycle is compromised.

How Practolytics Helps: 

We track all expiration dates for every provider in your group. You get automated alerts well in advance, so there’s no last-minute scramble or revenue disruption.

Mistake #4: When “One Size Fits All” Falls Flat

Credentialing is not universal. Different specialties face different credentialing hurdles. A pediatrician credentialing with Medicaid isn’t facing the same process as an orthopedic surgeon dealing with workers’ comp networks.

That’s where most in-house teams struggle—they try to use the same process for every provider, every payer, and every location. That just doesn’t work.

How Practolytics Helps: 

We’ve supported 28+ specialties, including psychiatry, cardiology, orthopedics, podiatry, primary care, and more. Our credentialing team understands specialty-specific rules, payer nuances, and state-by-state regulations. We tailor your credentialing roadmap to match exactly how your practice operates.

Here’s What the Real Cost Looks Like

To truly understand how costly these mistakes can be, take a look at the breakdown below:

Credentialing mistakes don’t just delay payments. They completely stop the flow of revenue until they’re corrected—and by then, you’ve lost weeks (or months) of income.

A Quick Word on Group vs. Individual Credentialing

Here’s a technical but critical misstep: when a new provider joins your practice, they need to be credentialed individually and also linked correctly to your group NPI and TIN. Many practices overlook this linkage part and assume being credentialed individually is enough.

It’s not. Without the link, payers will treat the provider as out-of-network—even if the group is already in-network.

How Practolytics Helps: 

We ensure every credentialing case includes proper group-affiliation verification. Our credentialing managers manually confirm this with payers so you can bill under your group’s NPI without issues.

Mistake #5: Not Linking the Provider to the Group NPI Correctly

This might sound like a small administrative detail—but in credentialing, small mistakes have big consequences.

When a new provider joins your practice, most teams focus on getting them credentialed with payers individually. But they miss a key step—linking that individual provider to the group’s NPI and Tax ID.

If this doesn’t happen correctly, payers won’t process claims under your group contract. Even worse, the provider might show as out-of-network, even if your practice is in-network.

The Fix with Practolytics: 

We go beyond credentialing forms—we ensure each provider is formally affiliated with your group TIN and NPI across all payers. Our credentialing managers follow up directly with payer reps to verify this connection is recognized and active before the provider starts seeing patients.

Mistake #6: Not Following Up with Payers After Submission

This one is huge.

Many practices assume that once they submit an application, the payer will take care of the rest. Unfortunately, that’s not how it works. Credentialing departments at payer organizations are often overwhelmed. Applications sit in queues, requests for clarifications go unanswered, and no one’s calling you back.

If you’re not actively following up, you might not even know your application was marked incomplete weeks ago.

The Fix with Practolytics:

We maintain weekly follow-ups with every payer until credentialing is complete. Our team documents every interaction, escalates when needed, and ensures your application doesn’t fall through the cracks. You’ll always know exactly where things stand—without having to chase anyone.

Mistake #7: Forgetting About Re-credentialing and Re-attestation

Credentialing isn’t something you do once and forget.

Most commercial and government payers require re-credentialing every 2–3 years. If you miss that window, the provider is automatically deactivated. You could be billing for weeks without realizing claims are being denied—and now you’re not just dealing with credentialing, you’re cleaning up billing chaos.

Here’s the scary part:

Some payers don’t send warnings. They just cut off participation when re-credentialing deadlines are missed.

The Fix with Practolytics:

We track every re-credentialing and re-attestation deadline and begin the process months in advance. From CAQH re-attestation to re-enrollment with Medicare and commercial plans, we handle the full cycle—so your providers stay in-network and your payments stay uninterrupted.

Why These Mistakes Keep Happening (and How to Break the Cycle)?

The truth is, credentialing is too complex to be handled as a part-time responsibility. In most practices, it gets passed between office managers, medical billing staff, or administrators who already wear too many hats. With limited payer access, evolving rules, and a mountain of documentation, it’s easy to understand why even the best teams get overwhelmed.

And unfortunately, the cost isn’t just administrative. According to a report by the Council for Affordable Quality Healthcare (CAQH), inefficient credentialing processes contribute to over $2 billion in excess administrative costs each year in the U.S. healthcare system.

That’s why we believe it’s time for a smarter approach.

Why More Clinics Are Now Outsourcing Credentialing?

Let’s have a real moment here.

Outsourcing credentialing doesn’t mean giving up control. It means giving up the stress, the missed deadlines, and the uncertainty. You stay informed and in charge, while credentialing specialists take care of the details you shouldn’t have to worry about.

Here’s what you gain when you outsource to a team like Practolytics:

• Faster approvals because we have dedicated payer contacts

• Ongoing compliance with zero missed expirations or deadlines
  
• Customized workflows built around your specialty, payers, and goals
  

You also free up your internal team to focus on patient care, growth, and operations—instead of chasing credentialing status updates.
