Is there any waiting period for claims under a Family health plan?

When you buy a family medical insurance policy for the first time, there is a waiting period of 30 days before you can file a claim under the policy coverage, starting from the coverage commencement date. During this period, no claim will be accepted by the company. But this waiting period of 30 days is waived off in case the hospitalization is due to an accident. Policies that are pending for renewal do not have any such waiting period applicable.
