Credentialing a group practice is not one process, it is two running in parallel: an organizational track for the practice itself, and an individual track for every clinician inside it. The organization gets its own Type 2 National Provider Identifier (NPI) from CMS and typically holds the actual payer contracts; each clinician separately keeps their own Type 1 NPI, which never changes no matter where they work. Most payers still require each clinician to maintain their own CAQH ProView profile and individually authorize the payer to view it, even though the group is the one contracted. For Medicare specifically, the individual enrolls on a CMS-855I, the group enrolls on a CMS-855B, and the individual's Medicare benefits are then reassigned to the group, a link that either side can end without touching the individual's own underlying Medicare enrollment.
What happens when a clinician leaves the group is not settled by one universal rule; it is payer-specific, so check the actual contract rather than assume. The one piece that is federally defined, Medicare's reassignment of benefits, follows the clinician, not the group: ending a reassignment leaves the individual's own Medicare enrollment untouched.
Does the group's credentialing cover its clinicians too?
No. The group's own credentialing and each clinician's own credentialing are two separate tracks that both have to be done, not one process that substitutes for the other. The organization becomes a contracting entity with its own identity to payers; each clinician inside it is independently checked against the same payer's credentialing standards. A group holding a contract does not mean every clinician automatically bills under it until that clinician's own piece is also complete.
Why does a group need two different NPIs?
Because CMS treats the organization and the individual as two separate enumerated entities, each with its own NPI, and a claim needs both. CMS's own NPI guidance defines Entity Type 1 (Individual) for practitioners, including sole proprietors, and Entity Type 2 (Organization) for a group practice, facility or corporation. On a standard CMS-1500 claim, the individual clinician's Type 1 NPI goes in the rendering-provider field and the group's Type 2 NPI goes in the billing-provider field. A clinician's Type 1 NPI is permanent and travels with them to any future employer; the group's Type 2 NPI stays with the organization regardless of which clinicians come and go.
| NPI type | Who applies | Does it change if the clinician moves? | |
|---|---|---|---|
| Individual clinician | Type 1 | The clinician, with their own SSN or ITIN | No, it is permanent |
| Group practice | Type 2 | The organization, with its EIN | No, it stays with the organization |
Does joining a group mean I no longer need my own CAQH profile?
No. Most payers still require each individual clinician to keep their own CAQH ProView profile current and to separately authorize each payer to view it, even though the group as a whole holds the contract. A practice manager can use CAQH's group tooling to enter shared details once (the practice's own name, address and tax ID), but the clinical and credentialing content of the profile is still submitted and attested to by the individual, on a roughly 120-day re-attestation cycle. If a payer cannot see an individual's authorized, current profile, that clinician's own piece of the group's credentialing is not actually finished, regardless of the group's own contract status.
A group contract is not a shortcut around CAQH. It can make the paperwork easier to coordinate, since shared details are entered once, but it does not remove any individual clinician's own profile, attestation or payer authorization requirement.
How does this work specifically for Medicare?
Medicare enrolls the individual and the organization separately, then links them through a reassignment of benefits, which either side can end on its own. The individual practitioner enrolls using CMS-855I; the group or organization enrolls separately using CMS-855B. Once both are enrolled, the individual reassigns their Medicare billing rights to the group, typically through PECOS online or the paper CMS-855R process; both the individual and the organization have to be enrolled, or concurrently enrolling, before that reassignment can take effect. Ending the reassignment later does not cancel the individual's own underlying Medicare enrollment, which is theirs independent of any group.
What happens if a clinician leaves the group? Does their credentialing go with them?
It depends on the payer and the specific contract; no single federal rule or cross-payer standard settles this, so check the actual agreement rather than assume either way. The one piece that is federally defined is Medicare's reassignment mechanic: because the individual's own Medicare enrollment is separate from the group's, ending the reassignment when someone leaves does not touch their personal enrollment, so they can reassign those same benefits to a new employer without re-enrolling from zero. For commercial payers, whether a departing clinician stays in-network, needs their own new contract, or loses network status immediately is set by that specific payer's own provider agreement, and it varies.
What the group needs
Its own Type 2 NPI, its own payer contracts, and (for Medicare) its own CMS-855B enrollment, kept current regardless of staff changes.
What each clinician needs
Their own permanent Type 1 NPI, their own authorized CAQH profile, and (for Medicare) their own CMS-855I enrollment that stays theirs if they ever leave.
Where does Telesure fit in this?
Telesure is not a payer or a credentialing vendor; it matches a clinician or a practice manager with an independent licensing and credentialing specialist who can map out exactly which pieces are organizational, which are individual, and what a specific payer's own contract says about departures, before anything is submitted.
Adding a new clinician to an existing group contract is still two tracks, not one. Even where a payer lets new hires join an existing group agreement quickly, that clinician's own individual credentialing, CAQH profile and NPI still have to be in place; the group's contract speeds up the organizational side, not the individual one.
Need this handled rather than researched?
Telesure matches clinicians with licensing and credentialing specialists so you can compare scope, timeline and price before committing to anyone.
