In case hospitalization expenses exceed the pre-approved amount; you can approach the Corporate / TPA Help Desk to apply for an enhancement of the pre-approved amount. In case you have not exhausted your medical insurance limit, it is most likely that your TPA will approve the application for the enhancement either for the requested enhanced amount or up to your insured limit after deducting the value already utilized by you during the year whichever is less. If the TPA turns down the request for enhancement you will need to pay the amount incurred in excess of your approved amount directly to the hospital before the discharge.
