We Hired a New Provider. Now What?

By Brad Becker, CRCR, Regional Billing Manager at AMS Solutions. 14-page printable PDF, free.

The offer letter is signed, the start date is on the calendar and the practice is preparing the schedule. What needs to happen before you can bill insurance for this provider under your practice? Hiring a provider and adding that provider to your payer contracts are two different processes. A clinician may already have an NPI, an active CAQH profile, Medicare participation and several commercial credentials, and still not be ready to bill under your group. The core question the onboarding process must answer is simple: is this provider properly connected to this practice for this payer?

What’s inside

Who it’s for

Practice administrators, office managers and credentialing coordinators onboarding a new physician, NP, PA or other clinician, and owners who want to know why “they’re already credentialed” is not the end of the conversation.

First, separate the moving parts

Credentialing conversations get confusing because several related processes are described with the same word. An NPI identifies an individual provider (usually Type 1) or an organization (usually Type 2); it does not mean the provider is enrolled or credentialed with any payer. Credentialing is the payer or organization verifying professional qualifications such as licensure, education, training, malpractice coverage and work history. Enrollment establishes the provider with a payer so services can be billed and processed under that payer’s requirements. Group affiliation or reassignment is the payer recognizing the relationship between the individual provider and your practice; for Medicare this may involve reassignment of benefits to an enrolled organization, while commercial payers use different terminology.

The most common misunderstanding: “the provider is already credentialed.” That does not automatically mean the provider is ready to bill through your group. Existing payer relationships may be tied to another practice, location or billing arrangement. The goal is not simply to verify the provider; it is to connect the provider, the practice, the location and the payer correctly before claims begin flowing, which is why credentialing should begin before the provider’s first day whenever possible.

Steps 1-3: build the foundation before you apply

Build the provider file once and use it across every payer application: full legal name and contact information, date of birth and SSN, individual NPI and taxonomy, professional license information, DEA registration where applicable, CAQH information, Medicare and Medicaid information where applicable, education and training history, work history with gap explanations, board certification, malpractice coverage, CV and certificates, the group NPI, TIN, locations and W-9, and the provider start date and practice contacts. Review NPPES: do not assume the NPI record is accurate because an NPI exists, and remember that updating NPPES does not update every payer or Medicare record. Review CAQH: for many commercial plans it is a core part of the file, so check demographics, licenses, malpractice, education, work history, practice information, supporting documents, authorizations and attestation status before submissions begin. A weak foundation multiplies the same problem across every application.

Step 4: build the payer map

Do not apply everywhere. Start with the plans that matter to the practice and the population the provider will actually see: Medicare, state Medicaid, Medicaid managed-care plans, major commercial plans, Medicare Advantage plans, specialty networks, workers’ compensation or other relevant programs, and any payer important to the current patient population. Then create a payer-by-payer tracker: is the group already participating, is the provider already participating, does the provider need individual credentialing or group affiliation, is a roster submission sufficient or is a full application required, does the payer require contracting, are additional documents needed, has the application been submitted, what is the confirmed effective date, is the provider actually loaded in the payer’s system, and who owns the next action. Do not stop at “approved”: approval on paper and readiness in the payer’s claims system are not always the same moment.

Steps 5-6: Medicare and Medicaid need their own workflows

Medicare enrollment is managed through PECOS. When an eligible practitioner will bill through a Medicare-enrolled organization, the reassignment relationship must also be established. The question is not “does this provider have Medicare?” but “is this provider properly enrolled and connected to our Medicare group?” Confirm the individual enrollment, the organization enrollment, the reassignment, the practice location and the effective date before treating the provider as billing ready. Medicaid is state-specific and should not be treated as an extension of Medicare; the provider may need state enrollment, group affiliation, managed-care enrollment, location additions or other state-specific actions. A provider enrolled through another organization may still need updates before billing through your practice. Do not let “they already have Medicaid” end the conversation.

Step 7: commercial payers, payer by payer

Commercial requirements vary substantially: one payer requires full credentialing, another relies on CAQH, another accepts a roster add, another uses a provider-add form, a contract amendment or a location action. The requirement can change by provider type, specialty, location, state, existing group contract or payer product. There is no reliable button labeled “add this provider to every insurance company.” The safest model is payer-by-payer ownership and tracking.

Step 8: submitting the application is the beginning

Every application should carry a clear status: not started, ready to submit, submitted, pending, additional information requested, approved, effective date confirmed, loaded and billing ready, or escalation needed. “Pending” is not a credentialing strategy. If an application has been pending for weeks, ask when it was submitted, whether receipt was confirmed, whether it is complete, whether information was requested, when the last follow-up was, whether there is a case number, what the next action is and who owns it.

Protect the revenue before the schedule fills

A provider’s employment start date and payer effective date are not automatically the same. The provider may be ready for EHR training and clinical orientation while enrollment is still being completed. Before scheduling insured patients, understand the provider’s status with each applicable payer; seeing the patient and getting paid correctly for the visit are two different questions. Should you hold claims until credentialing is complete? Sometimes, but never as an automatic strategy without understanding payer rules, effective dates, timely-filing limits, retrospective-billing policies and contract requirements, and never without knowing which claims are held, for which payer and provider, why, what effective date is expected, what the filing deadline is and who is monitoring them.

Finish the last mile

Credentialing does not end at the approval email. Verify what was actually approved: provider identity, group or billing entity, service location, effective date, network or product, billing information, payer-specific limitations and whether the billing team can confirm readiness. Then make sure the information reaches billing, scheduling, the front desk, practice management, coding and the provider. If billing does not know the provider became effective, claims stay held unnecessarily; if scheduling assumes participation before confirmation, the opposite problem occurs. A provider already with the same payers makes parts of the process easier, but never confuse participating with the payer with participating with the payer through your group. A provider who works at multiple practices still needs your organization’s own affiliation, location, billing arrangement and effective-date details configured correctly.

Timing and red flags

Once the start date is firm and you have the information to begin, credentialing should move. Processing times vary by payer, provider type, market and completeness, so no universal timeline is reliable; work backward from the start date. Watch for these phrases: “They are already credentialed, so we are good” (maybe; verify the relationship with your group). “We submitted everything, now we just wait” (submission without follow-up is not credentialing management). “Everything is pending” (with whom, since when, for what reason?). “We will just bill it once they start” (that creates denials, filing-limit exposure and avoidable A/R). “Billing will figure it out” (billing cannot manufacture enrollment after the claim denies). “The payer approved them” (what effective date, group, location and product?).

The checklists and the five questions

The downloadable guide includes a provider-readiness and practice-readiness checklist to use before applications go out, and a payer plan and application management checklist that runs from “Medicare reviewed” through “billing team notified” and “provider released for scheduling.” Before the provider’s first day, ask: Which payers is the provider completely ready to bill? Which are still outstanding? What is preventing each one from being completed? What happens to patients scheduled with those plans? Who owns every remaining credentialing task? The simplest way to think about it: who are they (NPI, licenses, CAQH), where are they practicing (group, tax ID, locations), who needs to recognize the relationship (Medicare, Medicaid, commercial plans) and when can we bill (confirmed effective dates, affiliations and payer readiness). A strong onboarding process connects credentialing, operations, scheduling and billing.
