AIDS Adjustments

120.4 - AIDS Adjustments (Rev. 4409, Issued: 10-04-19, Effective: 11-05-19, Implementation: 11-05-19) As under the previous RUG-IV model, patients with a “B20” ICD-10 diagnosis code on the SNF claim, meaning the patient has AIDS/HIV, receive an adjustment factor for their PPS rate. Under PDPM, the adjustment factor is different from that used under RUG-IV. Rather than a 128 percent adjustment for the entire PPS per diem rate, the adjustment under PDPM is an increase of 18 percent in the nursing component of the per diem rate and a reclassification under the NTA component to a higher rate category. All other adjustment factors, such as adjustments for geographic variation in wage costs, remain the same under PDPM as under the previous RUG-IV model.
