That number sounds enormous because it is. And the part that drives me absolutely nuts is how much of it is preventable. When practices come to us after a run of denial issues, we almost always trace at least a portion of the problem back to the same root causes — and they're all solvable.
Let me break down the credentialing-specific denial types we see most often and the system we've built to make them stop happening.
The Credentialing-Related Denials That Hit Practices Hardest
Provider's payer enrollment expired or lapsed. Every claim during the gap gets denied. Recovery is nearly impossible retroactively — most payers won't pay for dates of service during a lapse period even after enrollment is restored.
The billing provider NPI or TIN doesn't match what's in the payer's enrollment system. Often caused by a recent practice change, address update, or NPI reassignment that wasn't updated with payers.
The claim goes out in-network but the provider isn't actually credentialed yet, or their contract hasn't taken effect. The patient owes the full bill. The practice has an angry patient and uncollected revenue.
Provider is enrolled but opted out of Medicare or a commercial plan without fully understanding the billing implications. Claims go out with wrong participation status.
Our Solution: Build the Prevention In, Not the Reaction
Most practices manage denials reactively — they get a denial, they figure out why, they try to fix it and resubmit. That system works sometimes, but it's expensive in time and often fails because payer timely filing deadlines have already passed.
Our approach with every managed client is to build the prevention layer so the denial never happens in the first place.
✅ Proactive Enrollment Calendar
We maintain a rolling 12-month calendar of every enrollment expiration and re-credentialing date for every payer contract our clients have. We start the renewal process 180 days out. By the time an expiration date arrives, the new approval is already in hand.
✅ Billing-Credentialing Reconciliation
Every month we cross-reference the provider data in the billing system against the enrollment data on file with each payer. NPI, TIN, effective dates, practice address — if anything is out of sync, we flag it before a claim goes out with wrong information.
✅ New Provider Lock
No new provider bills through a payer until their enrollment is confirmed — not just submitted, confirmed. We maintain a "billing hold" list that the billing team checks before activating any provider in their PM system for a given payer. This sounds simple, but it's the single biggest thing that prevents out-of-network denials on newly hired providers.
✅ CAQH Maintenance on a 90-Day Cycle
CAQH expiry causes payers to start treating your enrollment as unverifiable. We re-attest every CAQH profile on a 90-day cycle without exception. No expired profiles, no silent credentialing failures downstream.
What to Do If You're Already Getting Credentialing-Related Denials
First, pull three months of denial reports and identify every denial with a reason code related to provider enrollment, participation status, or billing provider information. Look for patterns — same payer? Same provider? Same denial reason? That pattern tells you exactly where the credentialing breakdown is.
Second, contact the payer and request a status check on the provider's enrollment. Sometimes what looks like a credentialing problem is actually a data mismatch that can be corrected with a simple provider update form. Don't assume you need to re-credential from scratch until you know exactly what the payer sees on their end.
Third, ask your billing team when they last cross-checked provider data against payer portals. If the answer is "never" or "I don't know," that's your action item today.
