Switching TPAs without disrupting claims

Updated October 21, 2026

To switch TPAs without disrupting claims, start early, read the termination and run-out terms in your current contract, and move eligibility, accumulators, authorizations and open cases to the new TPA before the effective date. Line up stop-loss coverage so no claim falls between policies, and get new ID cards and updated plan documents to members before they need care.

When is it time to switch TPAs?

It is time to look when routine monitoring keeps finding the same problems and the TPA does not fix them. DOL says an employer should review its service providers at reasonable intervals and decide whether to keep them or look for replacements, which includes reviewing performance, reading reports, checking actual fees and following up on participant complaints.

Common signs include:

• Repeated claim errors, reprocessing or backlogs of pended claims.
• Reports that arrive late, or claim-level data you cannot get. Plans may not agree to terms that restrict their access to de-identified claims data.
• Fees above the contract, or new charges that were never quoted.
• A steady stream of member and provider complaints.
• Compliance tasks that slip, such as files or notices the TPA agreed to handle.
• Stop-loss reimbursements denied for late or incomplete filings.
• A plan that has outgrown the TPA, with new states, a new plan type or services it does not offer.

If you are starting a search, the guide on how to choose a TPA covers the RFP and the questions to ask.

How long does a TPA switch take?

Plan on months, not weeks, and work backward from the effective date. Selection, contract notice, system build, data testing and member mailings all have to happen before the first claim arrives, and the outgoing TPA’s run-out work continues well after.

Timing the switch to the plan year usually keeps the moving parts in step. Stop-loss policies are written with one-year terms, and attachment points start over when a policy renews. Plan changes made outside a renewal can also trigger notice deadlines, covered below.

What should you check in your current TPA contract?

Check three terms first: how much notice you must give, who processes run-out claims, and how your data comes back.

• Termination notice. The length of the notice period, the date it must be received, whether it must be in writing, and any fees for leaving early.
• Run-out claims. Whether the outgoing TPA keeps processing claims incurred before the termination date, for how long, and at what fee. Include appeals on claims it decided. The National Association of Insurance Commissioners (NAIC) notes that some claims take as long as 18 months to run out, partly because of internal and external appeals.
• Data return. The format, fields, history and timing of the final data extract, and any fee. Under HIPAA, a business associate contract must require the business associate, at termination and if feasible, to return or destroy the protected health information it holds, so confirm you receive the data before it is destroyed.

The TPA contract is also where run-out, run-in and the transition process at renewal or termination should be spelled out. If it is silent, negotiate a transition agreement with the outgoing TPA.

What has to move to the new TPA?

The new TPA needs everything required to pay the first claim correctly and to honor what the old TPA already decided.

Eligibility files

Send a full eligibility file with history, dependents, COBRA participants and retirees, then test the ongoing feed and reconcile member counts before go-live. If COBRA administration is moving too, compare TPAs that list COBRA services.

Deductible and out-of-pocket accumulators

If the switch happens mid-year, transfer each member’s year-to-date deductible and out-of-pocket totals. Self-funded plans are subject to out-of-pocket maximum limits, so the new TPA needs those totals to apply the limit correctly. Even at a plan year start, check carryover provisions and family accumulators.

Prior authorizations and open claims

Transfer open authorizations for scheduled surgeries, ongoing therapy and equipment, and agree that the new TPA will honor them through their end dates. Its review staff must be ready on day one: plans must decide urgent care claims within 72 hours and pre-service claims within 15 days. Agree in writing which TPA finishes open, pended and appealed claims.

Large and ongoing cases

Hand off case management files for transplants, cancer treatment, dialysis, high-risk pregnancies and other active cases, ideally with a call between the two care teams. If the switch also changes your network, the No Surprises Act gives continuing care patients, such as those in treatment for a serious and complex condition or receiving pregnancy care, up to 90 days of continued in-network terms when a provider’s network status changes in the situations the law covers. Ask your benefits counsel whether your change triggers those protections.

Pharmacy, if the pharmacy benefit manager changes

Move open refills, mail-order prescriptions and specialty drug authorizations, compare formularies, and put the new pharmacy information on ID cards. Settle which vendor supplies which data for the plan’s prescription drug data collection (RxDC) report. The pharmacy benefits filter shows TPAs that list that service.

Compliance tasks

Reassign recurring duties. If a TPA agrees to post Transparency in Coverage files and fails, the plan violates the disclosure requirements. Decide who submits the gag clause attestation due each December 31 for the year of the switch.

How do you keep stop-loss coverage aligned?

Match the stop-loss contract basis to the TPA handoff so every large claim falls inside a policy period. Providers do not always file right away, so a claim incurred before the switch may be paid after it.

Without an extension, a stop-loss policy reimburses only claims incurred and paid in the same policy year. Two extensions fill the gap:

• Run-out covers claims incurred during the 12-month contract period and paid within a stated period at least 90 days after it ends, in Louisiana’s definition. The NAIC notes this is commonly called tail coverage.
• Run-in covers claims incurred during a stated period before the effective date and paid during the contract period. The NAIC also uses the term nose coverage.

Contracts are named with two numbers. A stop-loss disclosure form published by Nevada’s Division of Insurance explains that the first is the months covered and the second is those months plus the run-out period, so a 12/15 has a three-month run-out. A 15/12 runs the other way, covering claims incurred in the three months before the effective date and paid during the 12-month contract.

Before you give notice, confirm the stop-loss carrier accepts the change. Some stop-loss insurers end coverage if the employer changes TPAs, and the Texas Department of Insurance lists changing your TPA among the reasons coverage can end. Then check that the outgoing TPA’s run-out work fits inside the policy’s run-out window. The Nevada form warns that a plan sponsor may be fully responsible for claims paid outside stop-loss run-out periods. The stop-loss coordination filter shows TPAs that list that service.

What do members need to know, and when?

Members need new ID cards before the effective date, and the plan’s documents should reflect the new administrator.

• ID cards. Cards must show any deductibles, any out-of-pocket maximums, and a phone number and website for more information. Add the new claims address, provider service line and pharmacy details.
• SPD and SMM. The summary plan description (SPD) includes the claims procedure, procedures for using network providers and contact information, so a TPA change may require updates. A summary of material modifications (SMM) or updated SPD is due within 210 days after the end of the plan year in which the change was adopted, or within 60 days of adopting a material reduction in covered services or benefits.
• SBC. A material change that affects the summary of benefits and coverage, outside a renewal, requires notice 60 days before it takes effect.
• Plain instructions. Tell members what changes, what stays the same, where to call, and where to send claims for care received before the effective date.

What belongs on a TPA transition checklist?

A transition checklist should cover every handoff above, with an owner and a deadline for each.
