A TPA is the operational engine of a health policy: issuing e-cards, running the network-hospital helpdesk, approving cashless requests, and processing reimbursement claims. Employees rarely deal with the insurer directly - they deal with the TPA. TPA service quality (turnaround time, denials, helpline) hugely shapes how employees feel about their insurance, regardless of the policy on paper.
In India
Some insurers use in-house claims teams instead of an external TPA. A key renewal question is “who administers claims, and what's their cashless approval TAT?”
In practice
An employee is admitted at 9 pm. The hospital sends a cashless pre-authorisation to the TPA; the TPA approves ₹1.2 lakh within two hours, so the family walks in without paying upfront. Reimbursement, by contrast, would mean paying first and claiming back.
