TPA vs. In-House Claim Settlement Process in Health Insurance

Your hospital has your discharge papers ready, but you are still waiting for someone to say yes. Who that someone is depends on your insurer. It is either the insurer's own claims team or a separate company, called a Third-Party Administrator (TPA), hired to handle claims. This is the core difference between TPA and in-house claim settlement in health insurance, and it determines how many hand-offs stand between you and your money.

According to the IRDAI Annual Report FY 2024-25, 69% of health claims by number went through TPAs and 31% were settled in-house. But that split covers all policies together. Insurers mostly use TPAs for group policies, while large insurers settle retail claims themselves.

In this guide, we explain how each route works, which documents you need, and what to check before you buy.

What Is TPA-Based Claim Settlement in Health Insurance?

In TPA-based claim settlement, the insurer hires a third-party administrator to handle the day-to-day work on your claim. A TPA is an entity licensed by the Insurance Regulatory and Development Authority of India (IRDAI). It acts as the link between you, the hospital, and the insurer. The insurer retains underwriting authority and the final say on whether it approves or rejects a claim.

The claim process in health insurance moves like this under a TPA:

• Cashless: You show your TPA health card at a network hospital. The hospital sends a pre-authorization request with the treatment estimate. The TPA reviews the request against your coverage, limits, and exclusions, communicates the authorization under the insurer's claims arrangement, and issues an authorization letter. After discharge, it checks the final bill against the approved estimate and sends it to the insurer.
• Reimbursement: You pay the hospital and submit your claim to the TPA. It checks the claim for authenticity, completeness, and policy terms. It then forwards the claim with a recommendation to the insurer, which settles the amount.

Claims are only one part of a TPA's role in health insurance. It also:

• Issues health cards and handles basic policy service requests.
• Coordinates with network hospitals to keep cashless treatment running smoothly.
• Runs helplines and hospital help desks.
• Flags unusual billing patterns and reports claim turnaround data to the insurer.

Many insurers use TPAs in some form, although the extent and purpose differ. Some insurers use them to service group policies and empanel a larger hospital network. Newer or smaller insurers often rely on them more to set up operations and save costs until their own teams are ready.

Popular TPAs include Medi Assist, Family Health Plan (FHPL), MDIndia, Paramount, Vidal, HealthIndia, and Heritage. For the complete and current list, check the list of TPAs registered with IRDAI. 

What Is In-House Claim Settlement in Health Insurance?

In-house claim settlement means the insurance company handles the core claims process through its own claims team instead of relying on a Third-Party Administrator (TPA) to administer claims.

So, what happens when you raise a claim?

If your insurer follows an in-house claims model, its claims team is responsible for:

• Cashless Approvals: Reviewing the hospital's pre-authorization request and deciding whether to approve the claim.
• Medical and Policy Verification: Checking medical records, treatment details, and policy terms to determine claim eligibility.
• Queries and Communication: Raising additional queries with the hospital or policyholder when more information is needed.
• Reimbursement Claims: Reviewing and processing claims where you've paid the hospital bill upfront.
• Claim Escalations: Handling claim-related concerns, disputes, and follow-ups through the insurer's own claims setup.

But Here’s Something Worth Knowing: Not every insurer follows just one claims model. Some handle individual health insurance claims in-house while using TPAs for employer-provided or group health policies.

How Can You Check?

Look for Form NL-48 in the insurer's public disclosures. It provides information about claims handled in-house and through TPAs, helping you understand how the insurer manages its health insurance claims.

Here's what these disclosures show in practice:

• HDFC ERGO: Its NL-48 as of March 31, 2026, shows 7,72,379 claims received by the in-house team. It also discloses multiple TPAs servicing group policies.
• Niva Bupa: Its NL-48 as of March 31, 2026, states that it uses both in-house and TPA claim settlement. The in-house operation received 12,97,295 claims, while its 12 disclosed TPAs together received about 3.04 lakh claims, primarily across group policies. 
• Star Health: Its NL-48 as of March 31, 2026, identifies its primary claims setup as in-house. The disclosure reports 93,39,057 individual policies and 6,844 group policies serviced. Its in-house operation received 33,35,646 claims during FY 2025–26. 
• Aditya Birla: Its NL-48 as of March 31, 2026 states that it uses both in-house and TPA-based claim settlement. The in-house operation received 20,83,187 claims during FY 2025–26, while the insurer also disclosed multiple TPAs handling claims, primarily across group policies. 

TPA vs. In-House Claim Settlement: Key Differences

Regardless of who handles it, the health insurance claim process follows the same broad stages, from claim intimation and document review to authorization or reimbursement and final settlement. Regulatory timelines are the same for TPA-based and in-house claims. 

Ditto’s Take: For retail health insurance, we prefer established in-house claims teams because they remove one external layer from the process. But we do not judge an insurer on this alone. Actual TATs, complaints volume, and overall claims performance still matter more.

Documents Required for TPA and In-House Claim Settlement

The documents required for health insurance claims do not change based on whether a TPA or an in-house team handles it. The checklist depends more on whether the claim is cashless or reimbursement-based, and on the insurer's policy terms.

For cashless claims, the hospital generally shares the medical and billing documents directly with the insurer or TPA. These commonly include:

• Pre-authorization request
• Doctor's diagnosis and hospitalization advice
• Treatment estimate
• Investigation reports and medical records
• Final bill and discharge summary at discharge

You may still need to provide your health card or policy details and a valid photo ID. HDFC ERGO, for example, lists the pre-authorization form, ID proof, and health insurance e-card among the basic documents for cashless claims. 

For reimbursement claims, insurers commonly ask for:

• Completed and signed claim form
• Hospital bill with an itemized breakdown
• Payment receipts
• Discharge summary
• Prescriptions and investigation reports
• Pharmacy bills supported by prescriptions
• Photo ID or Know Your Customer (KYC) documents
• Bank details or a canceled cheque
• FIR or medico-legal report, where applicable for accident claims

The exact checklist varies by insurer, policy, and claim type, so check the claim section of your policy wording or insurer portal before submitting. 

Pros and Cons of TPA and In-House Claim Settlement

Pros and Cons of TPA-Based Claim Settlement

Pros

• Scales Well for Large Group Portfolios: TPAs can handle high claim volumes across employer and corporate health policies without the insurer having to build the entire servicing infrastructure internally.
• Broader Hospital Coordination: Established TPAs often work with multiple hospitals and can support smoother cashless coordination across different locations. 
• Useful for Smaller or Newer Insurers: Outsourcing claims administration can help insurers start servicing policies without immediately building a large internal claims operation.

Cons

• Adds Another Layer to the Claim Process: Queries, medical reviews, and escalations may require coordination between the hospital, TPA, and insurer.
• More Scope for Back-and-Forth: If the TPA needs clarification or insurer approval, communication can move across multiple teams before the claim progresses.
• Service Quality Can Vary by TPA: Your experience may depend not only on the insurer but also on the specific TPA handling your policy.

Pros and Cons of In-House Claim Settlement

Pros

• Fewer External Hand-Offs: The insurer's own team handles the claim, which can simplify coordination when additional information or escalation is required.
• More Direct Accountability: The claims team, escalation team, and insurer sit within the same organization.
• Better Control Over the Customer Journey: The insurer has direct visibility over claim servicing, turnaround times, and internal escalation.

Cons

• Performance Depends on the Insurer’s Own Systems: Weak processes, limited hospital coordination, or poor escalation can affect the experience even without a TPA.
• Less Useful as a Standalone Buying Metric: You still need to check actual turnaround times, complaints, and claims performance instead of assuming that in-house automatically means better claims.

Conclusion

Whether your insurer handles claims in-house or through a TPA can influence your claims experience, but it shouldn't be the only factor you consider.

For retail health insurance, we generally prefer insurers with established in-house claims teams because there are fewer external hand-offs during the claims process. However, a good insurer should also have a high claim settlement ratio, low complaint volume, a wide cashless hospital network, and a reliable claims support system.
