Most discussions about revenue cycle management focus on claims, denials, and collections, the parts of the process that happen after a patient is seen. But one of the costliest revenue bottlenecks happens before a provider sees a single patient: credentialing.
Credentialing and payer enrollment can take 60 to 180 days or more, depending on the payer and how complete the application is. During that window, a fully qualified provider may be unable to bill certain payers for the care they deliver, leaving a direct revenue gap for the practice.
Much of that gap can be shortened. Here is where the time goes, what it costs, and which parts you control.
What Credentialing Involves
Credentialing is the process a payer uses to verify a provider’s qualifications, including education, training, licensure, malpractice history, and work history, before adding the provider to its network. Payer enrollment then registers the provider so claims can be billed under the provider’s or practice’s identifiers. In practice, this usually means keeping an up-to-date CAQH ProView profile (which most commercial payers pull from), an active NPI in the NPPES registry, and, for Medicare, an approved enrollment through PECOS.
Both processes require extensive documentation, verification from primary sources such as medical schools and licensing boards, and often a committee review on the payer’s side. All of this takes time, and the practice cannot speed most of it up on its own.
5 Common Causes of Credentialing Delays
1. Incomplete or Inaccurate Applications
The most common cause is an incomplete application: missing documents, expired licenses or certifications, or unexplained gaps in work history. Payers usually stop processing until every item is provided, so each round of back-and-forth adds weeks.
2. Payer Processing Times and Backlogs
Each payer has its own processing timeline, and backlogs during busy periods can stretch it considerably. Practices often have little visibility into where an application sits in the payer’s queue.
3. Slow Primary Source Verification
Verifying credentials directly with medical schools, residency programs, and licensing boards can be slow, especially when those institutions are unresponsive or have their own backlogs.
4. Committee Review Cycles
Many payers hold credentialing committee meetings only monthly or quarterly. An application that misses one cutoff date waits for the next meeting, no matter how complete it is.
5. Starting Too Late
The most preventable cause. Many practices wait until a hire is finalized to begin credentialing instead of starting well before the new provider’s first day.
How Credentialing Delays Affect the Revenue Cycle
Lost Revenue
A provider who is seeing patients but is not yet credentialed with a payer usually cannot bill that payer for those visits. Services delivered during the gap may never be reimbursed.
Retroactive Billing Is Not Guaranteed
Some payers allow retroactive billing back to the provider’s start date once credentialing is approved, but not all do. Even when it is allowed, someone must identify and resubmit every affected claim, which is easy to miss without careful tracking.
Limited Scheduling and Patient Access
Some practices limit a new provider’s schedule to certain payers or self-pay patients until credentialing with major payers is complete. This restricts patient access and slows the provider’s ramp-up to a full panel.
Heavy Administrative Workload
When a provider must be credentialed with dozens of payers, tracking each application and following up on delays becomes a job of its own. It often falls to whoever has time rather than a dedicated credentialing specialist.
Locum Tenens Coverage Gaps
When delays leave a departing provider’s patients without coverage, some practices bring in locum tenens providers. Depending on payer policy, those providers may have separate credentialing requirements, which adds another layer of work.
6 Ways to Reduce Credentialing Delays
1. Start Early
Begin credentialing 90 to 180 days before the provider’s expected start date, depending on your payer mix. Do not wait until the hire is finalized.
2. Keep Every Provider File Complete and Current
Keep licensure, malpractice insurance, board certifications, and work history organized and up to date for every provider. Re-attest the CAQH ProView profile every 120 days as CAQH requires, because an expired attestation can stall applications at payers that rely on it.
3. Track Application Status Across All Payers
Do not wait for payers to contact you. Use a tracking system that flags applications nearing each payer’s typical processing time, so delays are escalated early.
4. Learn Each Payer’s Committee Schedule
Knowing when each payer’s credentialing committee meets lets you time submissions so you do not miss a cycle by a few days.
5. Confirm Retroactive Billing Policies Upfront
Before the provider starts, ask each payer whether retroactive billing to the start date will be allowed after approval, so your financial planning reflects a realistic revenue timeline.
6. Use Dedicated Credentialing Support
Credentialing takes specialized knowledge and constant follow-up. Practices onboarding several providers or entering new markets usually get better results from dedicated support than from adding it to someone’s existing workload. We compare both options in in-house vs. outsourced RCM.
Why Credentialing Is Often Part of RCM Services
Because credentialing directly affects when revenue starts coming in, many full-service revenue cycle management providers include credentialing and payer enrollment in their services. FAS Medical Summit offers medical credentialing services alongside billing, tracking application status across payers and helping practices start early enough to shorten the revenue gap when new providers join.
Credentialing Readiness Checklist
- Did credentialing begin at least 90 to 180 days before the provider’s expected start date?
- Is the provider’s documentation (licensure, malpractice insurance, board certifications, work history) complete and current?
- Is application status tracked for every payer the provider needs to enroll with?
- Have retroactive billing policies been confirmed with each payer in advance?
- Is there a plan for scheduling and patient access during the credentialing gap?
Start Credentialing Before You Hire
Credentialing delays are among the most preventable and most expensive gaps in the revenue cycle, especially while a new provider is onboarding. Practices that keep the gap short start early, track every application, and manage credentialing with the same discipline they apply to claims and denials.
If you are planning to add providers or join new payer networks, contact FAS Medical Summit to get credentialing support in place before the first patient visit.
