Kkh subsidies. Is it a norm to pay a medical fee to kkh when doing up on maternity insurance plan?

My gynae directed me to medical reporting unit to submit the insurance form for completion. However they came back asking to pay a fee $147 for the release of medical information to insurance provider. But the checklist from the plan is basically a yes or no question. I don't get why I need to pay this fee to kkh for them to release the medical information when it's just a yes or no checkbox. Is this a norm?,
