This October 1, the Patient-Driven Payment Model (PDPM) will introduce variable per-diem payment adjustments to providers paid under the Skilled Nursing Facility Prospective Payment System (SNF PPS). PDPM has five case-mix-adjusted components that each have an associated payment based on the case-mix group classification: physical therapy (PT), occupational therapy (OT), speech-language pathology services (SLP), nursing, and nontherapy ancillaries (NTA). For the PT, OT, and NTA components, case-mix group payments will decrease over the course of a Part A patient’s stay according to the predetermined schedules and adjustment factors found in Table 20, PT and OT Variable Per Diem Adjustment Factors, and Table 21, NTA Variable Per Diem Adjustment Factors, on page 6-48 of the draft version 1.17 Long-Term Care Facility Resident Assessment Instrument 3.0 User’s Manual.
