Hello out there;

I need help regarding coding for hemodialysis grafts - whenever we 
use the ICD code 996.7 for stenosis, thrombosis, etc of a access 
graft using the duplex of the access graft code we are denied 
payment.  Of course this is only a medicare problem, but every renal 
failure pt. is medicare.  Medicare tell us it has to be a problem 
because  from manufacturing of the device!!!  Any suggestions or 
other possible codes.  

Thanks - Gail UMMS
