How to claim a cashless facility in health insurance?

Today, most insurance companies in India offer cashless claim facility to health insurance policyholders. For cashless claim, the policyholder must seek treatment at any of the hospitals that is part of the insurer’s network. Upon completion of the treatment, the hospital files for a claim with the insurer, and the insurance company settles the bill directly with the hospital. Policy holders need not pay a single penny for cashless claim.
