HIPPS Updates and Structure Changes
120.1 - HIPPS Updates and Structure Changes
(Rev. 4409, Issued: 10-04-19, Effective: 11-05-19, Implementation: 11-05-19)
Under PDPM, the HIPPS code is structured differently, as a result of there being five
case-mix adjusted rate components under the revised model. The first position represents
the Physical and Occupational Therapy case-mix group. The second position represents
the Speech-Language Pathology case-mix group. The third character represents the
nursing case-mix group. The fourth character represents the Non-Therapy Ancillary
(NTA) case-mix group. The fifth character represents the AI code. CMS would note that
this also affects the number of potentially valid HIPPS codes under PDPM, as compared
to RUG-IV.
The PPS assessment schedule under PDPM is also significantly different from that used
under RUG-IV. The only assessments under PDPM that would produce a HIPPS code
would be the initial Medicare (“5-day”) PPS assessment, which follows the same
schedule as under the previous RUG-IV model, and the optional Interim Payment
Assessment (IPA), which may be completed at any point during a PPS stay.
