MNits 132 and 153 denial code?

Has anyone started having troubles in the past week or two that there claims are denying on MNits for 132 and 153? I've been calling nonstop to DHS but always get the message that there is too high of a call volume and get hung up on. We are billing SUD IOP and its happening to all of the codes, H2035, H2035 HQ, H0038 U8 and T1016 U8 HN. Anyone have any insight on this or gotten through to them? We have four locations and its happening to all four so I think there is something bigger going on that's effecting all the claims.
