§ 412.624 Methodology for calculating the Federal prospective payment rates.

(a) Data used. To calculate the prospective payment rates for inpatient hospital services furnished by inpatient rehabilitation facilities, we use—

(1) The most recent Medicare data available, as of the date of establishing the inpatient rehabilitation facility prospective payment system, to estimate payments for inpatient operating and capital-related costs made under part 413 of this subchapter;

(2) An appropriate wage index to adjust for area wage differences;

(3) An increase factor to adjust for the most recent estimate of increases in the prices of an appropriate market basket of goods and services included in covered inpatient rehabilitation services; and

(4) Patient assessment data described in § 412.606 and other data that account for the relative resource utilization of different patient types.

(b) Determining the average costs per discharge for fiscal year 2001. We determine the average inpatient operating and capital costs per discharge for which payment is made to each inpatient rehabilitation facility using the available data specified under paragraph (a)(1) of this section. The cost per discharge is adjusted to fiscal year 2001 by an increase factor, described in paragraph (a)(3) of this section, under the update methodology described in section 1886(b)(3)(B)(ii) of the Act for each year through the midpoint of fiscal year 2001.

(c) Determining the Federal prospective payment rates—(1) General. The Federal prospective payment rates will be established using a standard payment amount referred to as the standard payment conversion factor. The standard payment conversion factor is a standardized payment amount based on average costs from a base year that reflects the combined aggregate effects of the weighting factors, various facility and case level adjustments, and other adjustments.

(2) Update the cost per discharge. CMS applies the increase factor described in paragraph (a)(3) of this section to the facility's cost per discharge determined under paragraph (b) of this section to compute the cost per discharge for fiscal year 2002. Based on the updated cost per discharge, CMS estimates the payments that would have been made to the facility for fiscal year 2002 under part 413 of this chapter without regard to the prospective payment system implemented under this subpart.

(3) Computation of the standard payment conversion factor. The standard payment conversion factor is computed as follows:

(i) For fiscal year 2002. Based on the updated costs per discharge and estimated payments for fiscal year 2002 determined in paragraph (c)(2) of this section, CMS computes a standard payment conversion factor for fiscal year 2002, as specified by CMS, that reflects, as appropriate, the adjustments described in paragraph (d) of this section.

(ii) For fiscal years after 2002. The standard payment conversion factor for fiscal years after 2002 will be the standardized payments for the previous fiscal year updated by the increase factor described in paragraph (a)(3) of this section, including adjustments described in paragraph (d) of this section as appropriate.

(4) Applicable increase factor for FY 2014 and for subsequent FY. Subject to the provisions of paragraphs (c)(4)(i) and (c)(4)(ii) of this section, the applicable increase factor for FY 2014 and for subsequent years for updating the standard payment conversion factor is the increase factor described in paragraph (a)(3) of this section, including adjustments described in paragraph (d) of this section as appropriate.

(i) In the case of an IRF that is paid under the prospective payment system specified in § 412.1(a)(3) that does not submit quality data to CMS in accordance with § 412.634, the applicable increase factor specified in paragraph (a)(3) of this section, after application of subparagraphs (C)(iii) and (D) of section 1886(j)(3) of the Act, is reduced by 2 percentage points.

(ii) Any reduction of the increase factor will apply only to the fiscal year involved and will not be taken into account in computing the applicable increase factor for a subsequent fiscal year.
