What Credentialing Delays Cost a Practice, and How to Plan Ahead

A credentialing delay costs you every insured visit a new provider can't bill in network, while you are already paying their salary. Payers set their own processing times, and some take several months from a complete application to an effective date. What you control is when you start, how complete the application is, and how closely it is followed. Start late and the money is often gone for good: Medicare, for one, lets a newly enrolled physician or practitioner bill back only 30 days before the effective date.

What a delay costs: a worked example

The figures below are an example. Put in your own.

Say your practice hires a nurse practitioner who will see 16 insured patients a day, four days a week, at an average allowed amount of $110 a visit.

For those eight weeks you are paying the provider either way. You have three options, and none is free:

• Keep the schedule light. See self-pay patients and those whose payers have already approved the provider, and give up the rest of the visits.
• See patients and hold the claims. This works only if the payer will pay for dates before its effective date. Medicare allows up to 30 days back if circumstances prevented enrolling earlier (42 CFR 424.521). For a commercial payer it depends on its contract, so ask before you count on it.
• Bill under another provider's number. Don't. It is generally not allowed and creates compliance risk; Medicare permits it only in narrow cases such as locum tenens arrangements.

The cost shows up in other places too: patients who book elsewhere because the new provider is "not in network yet", claims that went out before the effective date and come back denied, and the staff hours spent reworking them.

Why enrollment is slow

• Every payer runs its own process. Medicare enrolls through PECOS or paper CMS-855 forms, each state's Medicaid program has its own, and each commercial plan has its own application, committee and timeline.
• The application isn't complete or doesn't match. A missing document, an expired license or malpractice certificate, or a name or address that differs between the application, the CAQH profile and the NPI record sends the file back.
• The CAQH profile isn't ready. Many commercial payers read a provider's data from CAQH, now branded DataSpring, powered by CAQH (Fierce Healthcare). A profile that isn't complete, attested and released to the payer holds the application up.
• Nobody follows up. An application can wait at the payer for one missing item without anyone at the practice knowing.
• It starts on the provider's first day. By then, the weeks before the effective date are already lost.
• Some panels are closed. A commercial network may not be taking new providers in a specialty or area, which you want to know before you promise patients.

A step-by-step plan for enrolling a provider

1. Start when the offer is signed. Collect the state license, DEA registration if they prescribe, board certification, the malpractice insurance certificate, a CV with work history and any gaps explained, the NPI, and the practice's tax ID and W-9.
2. Check the NPIs. The provider needs an individual (Type 1) NPI with a current address in NPPES. The group bills under its organizational (Type 2) NPI, and a new practice enrolls the group as well as each provider.
3. Bring CAQH up to date. Complete the profile, upload the documents, attest, and authorize each payer you are applying to so it can view the profile.
4. Apply to Medicare early. File the provider's enrollment and the reassignment of their benefits to your group in PECOS. The effective date is the later of two dates: the day you filed the application that Medicare's contractor goes on to approve, or the day the provider began seeing patients at that practice location (42 CFR 424.520(d)). Every week you wait to file is a week later the effective date can be.
5. Apply to Medicaid and each commercial plan. Start with the payers most of your patients use. When you apply, ask each one how it sets the effective date, whether it pays for visits before that date, and how long applications usually take.
6. Follow up on a schedule. Keep one log: payer, date sent, reference number, contact, what was asked for, and the next follow-up date. Check each open application every week or two and answer requests the same day.
7. Confirm before you bill. When a payer approves, get the effective date in writing and check that the provider is linked to the right group, tax ID and location. Then set the provider up in your billing system and open the schedule to that payer's patients.

Keeping a provider enrolled

Enrollment isn't one-time. Put these dates on a shared calendar:

• CAQH re-attestation every 120 days. A lapsed profile can hold up credentialing with the payers that use it.
• Medicare revalidation every five years (three for DMEPOS suppliers). CMS posts due dates up to seven months ahead on its revalidation list. A late revalidation can lead to a hold on payments or deactivation, and Medicare doesn't pay for services furnished while deactivated (CMS).
• Commercial re-credentialing, typically every three years.
• License, DEA and malpractice expiry dates, each on its own date.
• Changes you must report. Medicare gives physicians and other practitioners 30 days to report a change of ownership, an adverse legal action or a change of practice location, and 90 days for other changes (42 CFR 424.516(d)). Commercial payers set their own notice rules in their contracts.

Frequently Asked Questions

How long does medical credentialing take?

It depends on the payer. Each sets its own process and timeline, and some take several months from a complete application to an effective date, so there is no single number to plan around. Ask each payer when you apply. Missing documents and an incomplete CAQH profile are frequent causes of delay, and both are within your control.

What's the difference between credentialing and payer enrollment?

Credentialing verifies a provider's qualifications, licenses and history. Payer enrollment is the separate step of formally adding that provider to an insurance network so claims can be reimbursed. Both must be completed before billing.

Can a provider see patients before credentialing is complete?

Providers can see patients, but claims submitted before enrollment is finalized are often denied. Billing those visits under a different provider's number is generally not allowed and creates compliance risk; Medicare permits it only in narrow cases such as locum tenens arrangements. Medicare does let a newly enrolled physician or practitioner bill for services up to 30 days before the enrollment effective date, if circumstances prevented enrolling earlier (42 CFR 424.521).

How often does credentialing need to be renewed?

Commercial payers typically recredential every three years, Medicare requires revalidation every five years (three for DMEPOS suppliers) (CMS), and CAQH profiles need re-attestation every 120 days. Missing these deadlines can cause a provider to fall out of network unexpectedly.

Does credentialing apply to new practices as well as new hires?

Yes. New practices must complete credentialing and enrollment for every provider and often for the group itself (via NPI Type 2 enrollment) before any claims can be submitted to payers.

Where Beeline fits

Beeline's credentialing and enrollment service gathers the documents, checks that the details match across them, applies to the payers you choose, keeps the CAQH profile current, and follows each application until the provider has an effective date, then tracks re-credentialing dates. Payers still set their own processing times. That page's tool, "A credentialing checklist and your CAQH date", lists what to collect and works out your next re-attestation.
