# Enroll with payers, again
> Build a payer-by-payer enrollment and transition plan for a new state, entity, location, or acquisition without assuming contracts, identifiers, or effective dates transfer.
Payer participation is controlled by each contract and program. A new professional entity ordinarily has a new EIN and Type 2 NPI, but that alone does not tell you whether a payer requires a new contract, assignment, change-of-ownership filing, TIN addition, location addition, or provider-linkage update. Build the matrix before setting the closing or opening date. Use each payer's written determination as the authority for post-transition billing rather than relying on the purchase agreement.
## What must be determined again
| Item | Question for the payer or program |
| ------------------------------ | -------------------------------------------------------------------------------------------------------------------------- |
| **Group contract** | Is assignment allowed or consent required? Is a new agreement or TIN addendum needed? |
| **Delta Dental relationship** | Which member company serves the location, and what contract and credentialing process applies there? |
| **Type 2 NPI and TIN** | Which billing entity and identifiers must appear after the transaction or expansion? |
| **Rendering-provider linkage** | Is each dentist credentialed and linked to the correct entity, contract, and location for the date of service? |
| **Medicaid** | Which state enrollment, ownership/control disclosure, change-of-ownership, screening, and managed-care steps apply? |
| **Seller participation** | Does the payer permit assignment or continuation, require notice or consent, or require a new contract and effective date? |
| **EDI, ERA, and EFT** | Which submitter, receiver, bank, reassociation, and enrollment records must change, and when? |
| **Fee schedule** | Which schedule applies to the entity, provider, network, and date of service after the change? |
## What you may be able to reuse
Clean first-state records can reduce repeat work:
| | How it helps |
| ---------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| **Dentists' Type 1 NPIs** | Generally remain with the person. Add the new practice location in NPPES. |
| **CAQH profiles** | Update with the new state license and the new practice location; re-attest. No rebuild. |
| **Existing carrier relationships** | Ask whether the existing relationship supports a TIN or location add, provider link, or roster update, or requires a new agreement. Cigna maintains a DSO credentialing channel, and MetLife uses the multi-payer SKYGEN Dental Hub, but the required action remains carrier-, product-, entity-, and location-specific.1 |
| **Your process** | The tracking grid, the follow-up cadence, and the documents packet are all reusable. |
| **Malpractice carrier** | Often extends to the new state; confirm limits meet the new payers' minimums. |
**Contact existing payers' provider relations before applying.** Ask each carrier, Delta member company, Medicaid program, plan, or administrator whether the change is handled as a new agreement, assignment, TIN or location add, provider link, roster update, or another process. Do not infer the workflow from national branding.
## Delta Dental is 39 separate companies
"Delta Dental" is a national association of **39 independent member companies**, each serving a defined area.2 Participation with one member company does not by itself establish participation with another. Route through Delta's state-specific process and obtain the applicable member company's written contract, credentialing, location, and effective-date instructions.3
You also make the **Premier vs PPO decision again**, per member company: Premier's broader network and higher allowables against PPO's deeper discounts and steerage. The answer you reached in state one does not automatically hold in state two's market. See the [Delta Dental profile](/reference/payers/profiles/delta-dental).
## Medicaid means a new state-specific delivery-model analysis
States use fee-for-service, dental carve-outs, medical managed-care organizations with dental vendors, or mixed models. Complete state enrollment and any separate plan, administrator, contracting, credentialing, or affiliation steps required by the current delivery model; do not infer the count from the number of plan names.4
For Bluebird, the task is to start with the state agency's current provider and member materials, identify every applicable fee-for-service, managed-care, and dental-administrator path, and record the authorized claim receiver, contract, fee schedule, prior-authorization rules, and effective date. See [Enroll in state Medicaid](/guides/enrollment/enroll-in-medicaid).
If the entry is an acquisition, add a **change-of-ownership** workstream. The state program and each managed-care or dental administrator determine whether the facts require notice, a new enrollment, screening, revalidation, assignment, or new contracting. Do not infer the answer solely from whether the purchase agreement calls the transaction an asset or equity deal.
## Medicare, briefly
Traditional Medicare excludes routine dental by statute (SSA § 1862(a)(12)), so for most dental groups there is no Medicare enrollment to repeat.5 The exceptions worth checking as you expand: DMEPOS enrollment if you bill sleep-apnea appliances, and the narrow "inextricably linked" medical-dental scenarios. Medicare Advantage dental is separate again; those plans ride the same commercial and DBA infrastructure, with plan-by-plan contracts. See [Medicare and dental](/reference/payers/profiles/medicare-and-dental).
## Review network leasing again
A new state brings new proposed contracts and leasing terms. PPO networks may make contracted rates available to other payers, TPAs, and umbrella networks. One sign is an EOB from a payer the practice did not contract with directly that applies a network discount.6
Before signing anything in the new state:
* Read every proposed contract's **leasing and affiliate clauses**: who can access the rate, and whether you can opt out of downstream lessees
* Check the new state's leasing statute. Roughly 30 states require notice or opt-out rights, and Colorado's 2026 law requires affirmative opt-in consent before a dentist's contract can be leased.7
* Model the *effective* fee schedule per payer after leasing rather than relying only on the direct-contract rate
The ADA's Contract Analysis Service reviews proposed PPO contracts, including leasing clauses, free through state dental societies.6 See [Network leasing](/concepts/payments/network-leasing).
## Managing the revenue gap
The new PC may incur expenses before in-network revenue begins. Plan for that gap:
**Sequence the launch around written payer requirements, not an assumed clock.** Initiate each required application or change process as soon as the payer or program accepts it and the required entity, location, ownership, and transaction facts are available. Some processes require a service location, inspection, executed transaction document, or other evidence before processing.
**Fund the gap in a permitted, documented form.** Work with counsel and the CPA to choose the appropriate form, such as a loan, capital contribution, or another permitted arrangement. Document terms that account for professional-practice, entity, tax, solvency, and fair-market-value rules. See [Intercompany loans between DSO and PC](/reference/legal/intercompany-loan-note).
**Model lawful pre-effective-date care explicitly.** Depending on the payer contract, program rules, patient disclosures, and state law, options may include delaying covered care, cash-pay or membership-plan services, authorized out-of-network billing, or holding claims within the timely-filing period. Confirm the patient's network and cost-sharing treatment before scheduling; using the new entity's identifiers does not by itself authorize a claim. See [The No Surprises Act, briefly](/concepts/compliance/no-surprises-act).
**Ask about retroactive effective dates in writing** when the payer accepts the request. Some payers permit them under stated conditions; do not build the launch model on an unconfirmed date.
**Do not improvise a billing identity.** Before the first post-transition claim, obtain each payer or program's written determination of assignment, change-of-ownership or notice duties, TIN/NPI and location requirements, rendering-provider linkage, effective date, and any interim-billing process. Submit only under the identifiers and participation status authorized for that date of service. A purchase agreement cannot bind the payer, and an unsupported "out-of-network" label does not cure an inaccurate billing provider or enrollment record.8
## The tracking grid, expanded
Your single-state grid becomes a three-dimensional one. Track, per row:
| Column | Example |
| ------------------------ | -------------------------------------------- |
| Entity | Bluebird Dental of Texas, PC |
| Tax ID | 88-XXXXXXX |
| Group NPI | 1XXXXXXXXX |
| Payer | Delta Dental member company (TX) |
| Network | PPO / Premier; record which |
| Dentist | Dr. Tran |
| Contract status | Executed |
| Contract effective date | 2027-02-01 |
| Credentialing status | Committee review |
| Provider effective date | Pending |
| Leasing clause reviewed | ✅ opt-out exercised |
| EDI / ERA / EFT enrolled | ✅ (EFT → payer-authorized receiving account) |
| Timely filing limit | 90 days |
| Recredentialing due | Not yet set |
A spreadsheet may be sufficient at low volume. As the number of entities, payers, and clinicians grows, consider credentialing software when reminders, evidence, ownership, or reporting become difficult to maintain in one file. See [Track licenses, revalidations, and expirables](/guides/enrollment/maintain-revalidations).
