Who do you send a pre-existing questionaire to?

[Guest Damien]

I am hoping for some feedback on a procedure that I have never questioned before: who do you send a pre-existing lookback questionaire to? I always assumed the plan member. I spoke recently with someone who told me they send theirs to the person's treating physician, asking for medical records. In other words they never ask the member about prior treatment, diagnosis, etc.

I could see contacting the physician as a cross-check against the information provided by a member, but failing to ask the member at all seems imprudent to me.

Has anyone seen this approach before? I would be interested to know if this question is addresseed in the regs anywhere.
