Agree about the Med Exec approach. Coding convention states, report the service provided to the highest level of specificity. Many other scenarios fit in this question. How about a short dated ONeg unit that has been irradiated? Yep, you guessed it, you should report the services provided includding an irradiated unit that may have not been specifically by the phyiscian. Clinically this is important as well as reporting properly for cost accounting and claims preparation. I suggest you create a fairly extensive blood substituion policy, which most of us have it is just not formalized. This is a major step in inventory control. Sorry to highjack the topic...... :>)
