The Department of Health says it won't provide costs for each type of procedure undertaken at Noble’s Hospital.
It says introducing a costing system would be largely irrelevant because there is only one hospital on the Island.
The information is released by NHS hospitals in the UK but the department says that is because they are competing against each other for healthcare business.
MHK Howard Quayle raised the issue in Tynwald earlier this month saying a system of benchmarking was needed.
He says taxpayers must know where the £170 million budget is being spent:
Where has government found £11m in savings?
Is there border security for Irish sailings?
Emergency powers used to fell trees
Busy road in West to close next week
Free period products would cost £90k in 1st year
MHK wants to know about bail condition breaches
1,500 A&E patients weren't registered with GP
Will the Island's mad cow disease risk status improve?
