Special payment provision for short-stay outliers.

§ 412.529 Special payment provision for short-stay outliers.

(a) Short-stay outlier defined. “Short-stay outlier” means a discharge with a covered length of stay in a long-term care hospital that is up to and including five-sixths of the geometric average length of stay for each LTC-DRG.

(b) Adjustment to payment. CMS adjusts the hospital's Federal prospective payment to account for any case that is determined to be a short-stay outlier, as defined in paragraph (a) of this section, under the methodology specified in paragraph (c) of this section.

(c) Method for determining the payment amount—(1) Discharges occurring before July 1, 2006. For discharges from long-term care hospitals described under § 412.23(e)(2)(i), occurring before July 1, 2006, the LTCH prospective payment system adjusted payment amount for a short-stay outlier case is the least of the following amounts:

(i) One hundred and twenty (120) percent of the LTC-DRG specific per diem amount determined under paragraph (d)(1) of this section.

(ii) One hundred and twenty (120) percent of the estimated cost of the case determined under paragraph (d)(2) of this section.

(iii) The Federal prospective payment for the LTC-DRG determined under paragraph (d)(3) of this section.

(2) Discharges occurring on or after July 1, 2006 and before July 1, 2007 and discharges occurring on or after December 29, 2007 and before December 29, 2012. For discharges from long-term care hospitals described under § 412.23(e)(2)(i) occurring on or after July 1, 2006 and before July 1, 2007 and discharges occurring on or after December 29, 2007 and before December 29, 2012, the LTCH prospective payment system adjusted payment amount for a short-stay outlier case is the least of the following amounts:

(i) One hundred and twenty (120) percent of the LTC-DRG specific per diem amount determined under paragraph (d)(1) of this section.

(ii) One hundred (100) percent of the estimated cost of the case determined under paragraph (d)(2) of this section.

(iii) The Federal prospective payment for the LTC-DRG as determined under paragraph (d)(3) of this section.

(iv) An amount payable under subpart O computed as a blend of an amount comparable to the hospital inpatient prospective payment system per diem amount determined under paragraph (d)(4)(i) of this section and the 120 percent of the LTC-DRG specific per diem payment amount determined under paragraph (d)(1) of this section.

(A) The blend percentage applicable to the 120 percent of the LTC-DRG specific per diem payment amount determined under paragraph (d)(1) of this section is determined by dividing the covered length-of-stay of the case by the lesser of five-sixths of the geometric average length of stay of the LTC-DRG or 25 days, not to exceed 100 percent.

(B) The blend percentage of the amount determined under paragraph (d)(4)(i) of this section is determined by subtracting the percentage determined in paragraph (A) from 100 percent.

(3) Discharges occurring on or after July 1, 2007 and before December 29, 2007 and discharges occurring on or after December 29, 2012 and on or before September 30, 2017. For discharges from long-term care hospitals described under § 412.23(e)(2)(i) occurring on or after July 1, 2007, and on or before December 29, 2007 and discharges occurring on or after December 29, 2012, and on or before September 30, 2017, the LTCH prospective payment system adjusted payment amount for a short-stay outlier case is adjusted by either of the following:
