To my knowledge...., it would include...
the effective date of the patient's coverage;
type of plan that the member has coverage with;
if you are not in network, you should also verify if the patient has out of network benefits;
if you know the type of treatment that has been planned, you may also mention the same and verify if that would be covered;
coordination of benefits;
copay amount for office visits; etc.
Let me look forward for better answers.
