Nursing RUG with Therapy minutes on MDS

[BKRNAC48]

We just had an incident where a Medicare assessment had a RUG score of SE3, rather than RVB, as projected.  New Therapy company took over first of year and for some reason missed a day treating this woman (with one additional day treatment, resident would have been a RVB instead of RHB).  They did not miss anyone else.  Our last therapy company was just paid a small amount when this happened.  This manager mentioned billing a different way so therapy could be compensated for their high therapy minutes.  I had never heard of a "special billing code" before.   Thoughts or input?  Thanks in advance.
