Insurance Credentialing & Payer Enrollment Services

Insurance credentialing is the process of getting approved to join a payer’s network so your claims are paid in-network. It typically runs 90–150 days per payer and requires a complete provider file, an attested CAQH profile, and separate applications for Medicare, Medicaid and each commercial plan. Effective dates decide when you can actually bill.

Getting in-network is the gate between holding a license and getting paid. Do it yourself and it’s a part-time job: every payer has its own portal, its own forms, and its own queue — and one stale CAQH attestation or missing document quietly adds 60 days. Most delays aren’t the payer being slow; they’re files sitting untouched with nobody following up.

We run credentialing as a production process: your file is built once, applications go out clean, and every open application gets touched weekly until the panel says yes and the effective date is in writing.

Doing it yourself instead? Start with the provider credentialing checklist — every document, who issues it, how long it takes to obtain, and how often it expires.

Which payers we credential you with

Medicare. Enrollment runs through PECOS, and the application is federal — but the group structure underneath it is not boilerplate. Whether an added provider is straightforward or painful usually comes down to whether your PTAN and group setup can absorb them.

State Medicaid. In several states this is two steps, not one: you enroll with the state program first, and only then can each managed-care plan enroll you into its network. Texas works exactly this way through TMHP’s PEMS portal. Practices that file the plan contract at the same time as the state enrollment have not saved time — they have filed one application twice. See Medicare & Medicaid enrollment.

Commercial plans. BCBS, UnitedHealthcare, Aetna, Cigna and Humana are the core in most markets, and each one runs its own review on its own schedule. Nearly all of them pull your credentials from CAQH, which is why the profile gets built before anything is filed.

Regional and managed-care plans. The plans that decide real volume in a given market are often the ones missing from a national checklist — a locally operated Medicaid MCO, a provider-sponsored plan, a regional Blues affiliate. These are also the panels where network-adequacy arguments work best, because the plan actually knows it has a gap.

Panel strategy, before applications. Not every open panel is worth joining, and not every closed panel is permanently closed. Part of the work is telling you which panels in your specialty and geography carry enough volume to justify the file, and in what order to file them.

What the timeline actually looks like

These are the ranges we plan against, not best cases. The number that matters more than any of them is the effective date, because that is the first day a claim can be paid — not the approval date, and not the date you started seeing patients.

What we need from you

Roughly thirty minutes of your time, once:

• Current licenses for every state you practice in, plus DEA where applicable
• Individual NPI, and the group’s Type 2 NPI and TIN if you’re enrolling an entity
• Malpractice face sheet showing limits and dates
• Work history with month-and-year dates and any gaps explained
• CAQH login, or permission to create the profile for you
• The payers you want to join — or a conversation about which ones are worth it

Everything after that is ours. You will hear from us with status, not with requests to chase your own paperwork.

What actually delays applications

Almost none of it is exotic, which is exactly why a process fixes it.

A stale CAQH attestation. Profiles must be re-attested every 120 days. A payer pulling your profile mid-review finds expired data and stops — usually without telling you which item caused it. This is the most common invisible delay in credentialing.

Unexplained work-history gaps. Any gap beyond about 30 days triggers a reviewer query, and the file waits in the meantime. The gap is rarely the problem; the silence is.

Filing before the entity is settled. A group application whose EIN, ownership or NPI structure changes afterward does not get amended. It re-queues, and the position you waited two months for is gone.

Documents that expire mid-review. A license or malpractice policy that lapses during the payer’s review sends the application back to the start of the queue.

Nobody following up. The single largest difference between a 100-day file and a 200-day file is whether someone contacts the payer every week. Applications do not advance because time passes.

When a panel is closed

Closed does not always mean no. Payers are required to maintain adequate networks, and a closed panel with a genuine gap — an underserved specialty, a language need, a geographic hole, long appointment wait times — can be appealed on those grounds. We build that argument with the plan’s own network data where we can get it.

Sometimes the honest answer is that a panel is genuinely shut. When that is the case we say so rather than billing you to keep filing, and we redirect the effort to the payers that will actually open.

Where credentialing hands off to billing

This is the part most credentialing companies do not own, and it is where the money leaks.

Approval alone does not make a claim payable. What makes it payable is the effective date — the day the payer considers you in-network — and every payer treats the gap between “approved” and “effective” differently. Some backdate. Some allow a retro-billing window if you file within a set period. Some pay nothing before the effective date no matter what your approval letter says.

Get that wrong and the denials are entirely predictable: claims rejected because the provider was not enrolled on the date of service, or because the claim went out under a group the provider had not yet been linked to. Those denials are not billing errors. They are credentialing errors that surface in the billing system weeks later, usually after the timely-filing clock has started running.

So we close the loop: effective dates confirmed in writing per payer, retro-billing rules checked before you schedule against them, roster linkage verified so claims go out under the right group, and re-credentialing and revalidation dates diarized before they lapse. If we also run your medical billing, the same team owns both sides of that handoff — which is the whole point of running credentialing and billing as one pipeline instead of two vendors pointing at each other.
