Health and benefits TPAs
Health and benefits third-party administrators process medical claims, manage eligibility, networks, cost-containment programs and member service for employers that pay their own employee health claims. The employer keeps the claim risk and pays the TPA a fee to run the plan.

ActiveSeveral sponsors already own TPA platforms that are buying family-owned regional TPAs, but many independents remain and change of control needs only state notices.
- Fragmentation
- High
- Outside the carrier ASO units the market is made up mostly of regional independent TPAs.
- Universe from a public registry
- Medium
- Free state DOI lists name every licensed or registered TPA, but there is no national list and no size data.
- Recurring revenue
- High
- Admin fees are charged per enrolled employee each month and renew with the employer contract.
- Change-of-control friction
- Low
- The NAIC model requires notice to the regulator rather than prior approval, so the friction is mainly contract review and multi-state filings.
- AI operating leverage
- High
- Claims adjudication, eligibility, appeals and stop-loss filings are rule-driven document work done by large clerical teams.
Our view. For change-of-control friction, High means harder to close.

Registry
North Carolina Department of Insurance TPA Directory (one example of the state DOI lists). Lists every TPA licensed or registered to operate in North Carolina, with status, address and phone, and offers a CSV export. It covers life, health and annuity administrators, includes out-of-state firms, and has no size, lives or revenue data. There is no national registry, so a full US list means merging all state DOI lists and removing duplicates.
No public source gives a national count of health TPAs. Each state keeps its own list, and one TPA often appears on many state lists.
Our view
North Carolina requires a TPA license, but a firm that serves only ERISA-preempted employer plans registers with the state each year instead. Administrators of Section 125, HRA and HSA accounts must also register.
In 2026, 71% of covered workers were in a self-funded health plan, according to KFF.

In KFF's 2026 survey, 85% of covered workers at firms with 200 or more workers were in a self-funded plan, compared with 25% at smaller firms.

In KFF's 2026 survey, thirty-eight percent of covered workers at firms with 10 to 199 workers were in level-funded plans.

Brokers control most employer placements and re-bid TPAs at renewal. Client loss after a claims system conversion or a service drop is the most common value leak in a TPA deal.
Our view
Insurers sell most level-funded plans, which pulls small-group self-funding toward carriers. Venture-backed TPA software firms and carrier ASO units also compete on price and technology.

Fragmentation
A Fall 2024 market report by investment bank Hyde Park Capital describes the TPA sector as notably fragmented. It says the sector is made up mostly of regional service providers.

The same report says M&A has mostly been larger TPAs or insurers buying smaller competitors. It adds that outside investors have become more active in recent years.

The largest administrators of self-funded plans are the ASO units of the national health insurers. Independent TPAs split the rest, and even the leading independent platforms are small next to the carriers.
Our view
Revenue model
KFF says employers with self-funded plans typically contract with a TPA or an insurer to administer the plan.

The NAIC TPA model allows TPA pay to be based on premiums or charges collected or on the number of claims processed.

In KFF's 2026 survey, 75% of covered workers in self-funded plans at firms with 200 or more workers were in plans with stop-loss insurance.
Source: KFF, Oct 22, 2026
Core revenue is a per-employee-per-month admin fee on annual employer contracts, plus fees for networks, cost containment and stop-loss placement. Revenue recurs as long as the employer renews, and broker-led re-bids at renewal are the main churn point.
Our view
Change of control
Under the NAIC TPA model act, a TPA must notify the commissioner within thirty days of a material change in its ownership or control.
Source: NAIC, Oct 2011
North Carolina requires both licensed and registered TPAs to file notice of a change of ownership and of changes in officers or directors with the DOI.
The NAIC model bars a TPA from acting without a written agreement with the payor.
Source: NAIC, Oct 2011
The model sets a notice duty, not a prior approval like a Form A for insurers. The real friction is commercial, because a buyer must file notices in every state where the target operates and review each employer, stop-loss and network contract for change-of-control terms.

Where AI changes the cost base
Most TPA labor sits in claims examiners, eligibility and enrollment staff, member and provider service, and stop-loss and subrogation recovery teams.
Our view
Claims adjudication is rule-driven work that checks each claim against the plan document, eligibility, pricing and coordination of benefits. Appeals, stop-loss reimbursement packets and plan document drafting are also document heavy.
Our view
Many small TPAs run licensed legacy claims systems, so automation gains depend on migrating acquired books onto one platform. A rollup that consolidates systems first gets more from AI than one that leaves each add-on on its own stack.
