The Pre-Authorization Process for Cashless Claims, Explained

Pre-authorization is the insurer's (or TPA's) formal review and approval of expected treatment costs before — or very shortly after — hospitalization. It's the gatekeeping step for cashless claims, and understanding it helps you avoid last-minute surprises.

How pre-authorization works

1. The hospital's insurance desk fills a pre-authorization form with your diagnosis, planned treatment and estimated cost.
2. This is submitted to your insurer or TPA, usually electronically.
3. The insurer reviews it against your policy's sum insured, sub-limits, and exclusions.
4. An initial approval (sometimes for a partial amount) is issued, often within a few hours for straightforward cases.
5. If treatment costs change during hospitalization, the hospital submits an enhancement request for additional approval.

What can slow it down

• Incomplete clinical details on the initial form.
• A diagnosis that needs additional medical justification under policy terms.
• High-value claims that trigger additional insurer review.
• Submitting the request very close to a planned admission date instead of a few days ahead.
