Is it standard for insurance company to request you to allow them to access ALL your medical history from ALL hospitals when you are getting them to pay for a procedure?

Hi, I will be doing a minor procedure and have requested for a letter of guarantee from my employer's insurance company. The insurance company has this line on its letter of guarantee for me to sign "I agree and consent to XX company to request from ANY hospital, physician, person or organization, ALL information with respect to ANY illness, injury, medical history and copies of ALL hospital or medical records concerning myself at ANY time and and authorize the prior mentioned organizations to disclose all such information to XX company" whereby XX company is the insurance company. Is this normal?
