We'll map which payers you need and what to file first.

What does waiting on payers cost you?

Until a payer approves you, visits with its patients can't be billed to it. Move the sliders to match your practice.

Visits you can't bill yet

Every working day a payer is still processing your file adds to this number. Filing every payer at once keeps the longest wait from stacking on top of the others.

Changes

New providers and updates

Adding a doctor to your group, a new location or a new tax ID, updated with each payer.

From first call to first claim.

Four steps. You gather documents once; we handle the payers.

  1. Free credentialing plan

    We list the payers you need and the documents each one asks for.

  2. CAQH done first

    Your profile is completed and attested so commercial payers can pull it.

  3. All payers filed together

    Medicare in PECOS, Medicaid and commercial applications go out in the same window.

  4. Approved, then billed

    We follow up until each effective date. Then our billing team can take your claims too.

Built for where you are right now.

Pick your situation. We credential providers in all specialties, from solo practices to growing groups.

    Credentialing and billing under one roof.

    The team that enrolls you is the team that bills your claims, so we know which payers have approved you before the first claim goes out. No claims sent to a payer that hasn't loaded your enrollment yet.

    How long does credentialing take?

    Each payer sets its own clock. Industry-reported ranges are about 60–90 days for Medicare, 30–180+ days for Medicaid depending on the state, and 90–150 days for commercial payers.

    Because payers work in parallel, your total wait is set by the slowest payer you need. That's why we file them together and start as early as possible.

    What documents will you need from me?

    It varies by payer, but most applications ask for:

    • State medical license and DEA registration
    • Board certification and education details
    • Malpractice insurance certificate
    • CV with work history
    • NPI and practice tax ID (IRS letter or W-9)
    • Practice address and bank details for payments

    Your free plan includes a checklist for the payers you choose.

    Can I see Medicare patients before I'm approved?

    Medicare can allow physicians to bill retrospectively for up to 30 days before their enrollment effective date, if circumstances prevented enrolling earlier. The effective date is tied to when the application is filed, so filing early matters.

    Commercial payers and Medicaid programs set their own rules, so check each one before seeing their patients.

    Why does CAQH come first?

    Most commercial payers pull your information from your CAQH ProView profile. If it's incomplete or not attested, their applications stall. Completing it first lets every commercial application move at once. The profile also has to be re-attested every 120 days.

    What does credentialing cost?

    It depends on how many providers you have and how many payers you need. Your free credentialing plan includes a quote for your exact list, so you know the cost before anything is filed.

    I'm joining an existing group. Do I still need this?

    Yes. Each new provider needs their own enrollment with every payer, even if the group is already in-network. For Medicare, that also means reassigning your benefits to the group so it can bill for your visits.

    Get approved. Start billing sooner.
