ERA - MN-ITS - Modifier

Hello, we have recently starting billing using the UC modifier (UC = HH + U5) for Complex Medical Services. 

We are getting service agreements approved with the new Modifier even for our MICD clients. This way we can always under bill or have prior approval if the client upgrades their treatment from MICD to Complex/Co-occurring. 

We were told that since UC is a combiniation that include HH if we bill the HH rate they will only pay that. My question is when we look at the MN-ITS website we see they are paying the MICD rate; however, it shows the UC modifier still. Does it matter if the Modifier on the ERA does not match the treatment exactly. Again, they pay the correct rate. 

Just seems a bit weird to me. 

Thank you :)
