officers do not change what the clinician prescribed but actually, in testimony we heard earlier from pva, that is not the case, that their testimony states that contract officers when they do receive the orders, the request for the devices is modified and even denied in cases because of the cost. so that is a huge concern. there seem to be a disconnect from what you're hearing versus what the vsos are hearing because that is not the case. the cost is a factor. it's not the veterans' health care. so do you want to comment on that? >> yes, sir. thank you. first of all, contracting officers, all contracting officers do have a mandate under federal acquisition regulations to ensure that there's a price reasonableness aspect to the cost we are providing. i don't know if that is a concern or not. can't really speak to what may have happened before but i have put out to the contracting community that under 8123, if a contract -- if the contracting office receives a physician's consult for a specific product, we will do due diligence to ensure we pay a fair and reasonable price for that product
