Hello,  Help me please.  My providers are using a diagnosis of M72.6, necrotizing soft tissue infection but they are not sure what the "causative" organism is.  Path comes back as "polymicrobial" which I have researched and found could be either bacterial, viral or fungal or a combination.  How would we code for the NSTI, M72.6 with a finding of this polymicrobial organism?
