infections

[Suzieq130]

Hi all
have had a major controversy going on at our facility. Here is the question say you have a patient come in with MRSA in the nares with lab results but no s/s of infection.  Do you take it in I section, what if some one had +VRE in urine 6 months ago asymptomatic and never had repeat labs, do you take it in i section? What if you had some one with Hx of Hepatitis C on a consult do you code it under viral hepatitis?  And again a wound with MRSA which never had repeat labs and is healed over?
The CRC in our facilty will not claim if not active in past 7 days, state came in and said it has to be on the MDS during our survey and were cited for it.  Coorporate states not to take it unless it affects the current picture of patient.  What I am looking for and yes we read and reread the RAI manual,  but need to know what to do in these cases. Thanks in advance suzieq
