OB/GYN Credentialing & Payer Enrollment

Why credentialing is a revenue problem

Credentialing feels administrative, but every gap in it shows up directly in your collections. A new OB/GYN joins the practice and starts seeing patients — but she's not yet enrolled with two of your largest commercial plans. Claims go out under her name, the plans deny them, and by the time anyone notices, months of visits and a few deliveries are sitting in A/R with no clear path to payment.

The same thing happens when a CAQH attestation lapses, a Medicare revalidation is missed, a practice moves locations without updating enrollment, or a provider's taxonomy doesn't match how the claims are billed. Each of these is preventable.

We've handled OB/GYN credentialing and enrollment alongside billing for more than eight years, so we approach it with one question in mind: when can this provider's claims be paid, and is billing ready for that date?

What our credentialing service covers

Provider identifiers and setup

• NPI — Type 1 (individual) and Type 2 (organization) registration and updates in NPPES
• Taxonomy — 207V00000X for Obstetrics & Gynecology, or the subspecialty code that matches the provider's practice (see our OB/GYN taxonomy code guide)
• CAQH ProView — profile creation, document uploads, payer authorizations and quarterly re-attestation

Government payer enrollment

• Medicare — enrollment and revalidation through PECOS, reassignment of benefits to the group, and practice location updates
• Medicaid — state Medicaid enrollment and Medicaid managed care plan credentialing, which often run as separate processes
• TRICARE — regional contractor enrollment where applicable

Commercial payer credentialing and contracting

Applications to UnitedHealthcare, Aetna, Cigna, Blue Cross Blue Shield plans, Humana and regional plans — including follow-up until approval and confirmation of the effective date, fee schedule and provider ID.

Hospital privileges support

Coordination of the documentation hospitals typically request for obstetric and surgical privileges, so delivering providers can start on schedule.

Re-credentialing and maintenance

Payer re-credentialing cycles, Medicare revalidation, license and DEA renewal tracking, malpractice certificate updates and CAQH re-attestations — all on a calendar so nothing quietly expires.

OB/GYN credentialing specifics

Credentialing for women's health has a few wrinkles worth knowing:

• Subspecialty taxonomy matters. Maternal-fetal medicine, reproductive endocrinology and urogynecology providers may need subspecialty taxonomy codes to be recognized correctly in payer directories and for certain services.
• Midwives and advanced practice providers. Certified nurse-midwives and NPs have their own enrollment rules, and some payers require them to bill under their own NPI rather than incident-to a physician.
• Delivering providers and hospital affiliation. Some payers want hospital affiliation listed before they'll credential a delivering provider.
• Medicaid matters more in obstetrics. Medicaid covers a large share of births in the US, so state Medicaid and Medicaid managed care enrollment is often the most important application for an obstetric practice.

How we run a credentialing project

1. Intake. We collect licenses, board status, malpractice, education and work history, and practice information once — not separately for every payer.
2. Gap check. We compare existing enrollments against the payers you bill and identify what's missing or expiring.
3. Applications. Each application is completed, submitted and logged with a follow-up date.
4. Follow-up. We chase applications with each payer until they're approved, and resolve requests for additional information quickly.
5. Confirmation. Effective date, provider ID and fee schedule are recorded and shared with billing.
6. Maintenance. Re-credentialing and revalidation dates are tracked going forward.

Avoiding the credentialing revenue gap

The single best way to protect revenue when adding a provider is to start early — ideally as soon as the employment agreement is signed. While applications are in process, we help you:

• Schedule the new provider with patients whose plans are already effective
• Hold claims that can be billed later if a payer grants a retroactive effective date
• Avoid billing under another provider's NPI, which can create compliance problems

Credentialing and billing, together

Because we also handle revenue cycle management, credentialing status feeds directly into billing. Claims aren't released to a payer before the provider is effective, and credentialing-related denials are routed back to the enrollment team to fix at the source. If you're opening a new practice, see our new practice billing setup service, which includes enrollment from day one.

Common credentialing mistakes that cost OB/GYN practices money

These are the problems we see most often when a practice comes to us after a credentialing gap has already happened:

• Starting too late. The single most common issue. A new physician's start date is set before anyone opens a payer application, and the first two or three months of claims go out-of-network or deny outright.
• Incomplete CAQH profiles. A missing document, an expired malpractice certificate or an unsigned attestation can stall every commercial application at once, because most plans pull from CAQH.
• Wrong or mismatched taxonomy. The taxonomy on the NPPES record, the payer enrollment and the claim should agree. A gynecologic oncologist enrolled under the general 207V00000X code, or a midwife billed under a physician taxonomy, can trigger rejections and directory errors.
• Group vs. individual confusion. Commercial plans often need the provider linked to the group's tax ID and Type 2 NPI. If the individual is credentialed but never linked to the group contract, claims under the group can still deny.
• Missed Medicare revalidation. Medicare revalidates enrollment on a cycle, and a missed deadline can lead to deactivation — with a gap in billing privileges that's hard to recover.
• Location changes not reported. Opening a satellite office or moving the main office without updating payer records leads to claims denied for an unrecognized service location.

What we need from you to get started

To keep the process moving, we collect everything once and reuse it across payers:

1. State medical license(s) and DEA/state controlled-substance registrations
2. Board certification status (or board-eligible dates)
3. Current malpractice insurance face sheet and claims history
4. Education, training and work history with no unexplained gaps
5. Hospital privileges or admitting arrangements
6. Practice details: legal name, tax ID, Type 2 NPI, service locations and hours
7. A list of the payers you want to participate with, in priority order

Once we have those, we handle the applications, the follow-up calls and the paperwork requests — and we give you a simple status report so you always know where each application stands.

Credentialing for midwives and advanced practice providers

Certified nurse-midwives (CNMs), nurse practitioners and physician assistants are a growing part of OB/GYN care teams, and their enrollment deserves the same attention as a physician's. Some plans credential APPs fully and list them in directories; others only recognize them for incident-to billing under a supervising physician, which has strict requirements. Medicaid programs frequently enroll CNMs as independent billing providers. We map out how each payer treats each provider type so your schedule, billing and supervision arrangements line up with what the payer will actually pay.
