Can a listed hospital deny cashless hospitalization to me? What should I do?

Yes, there are instances when cashless hospitalization may be denied by a network hospital. Reasons are insufficient sum insured, inadequate information to justify hospitalization, discrepancy in details furnished, if the ailment is not covered by the policy and if the TPA does not receive preauthorization request in time. If any of these apply, the insured must bear the costs and claim reimbursement later as per policy terms.
