Section 510.315 - Composite quality scores for determining reconciliation payment eligibility and quality incentive payments(a)General. A participant hospital's eligibility for a reconciliation payment under § 510.305(g) , and the determination of quality incentive payments under paragraph (f) of this section, for a performance year or performance year subset depend on the hospital's composite quality score (including any quality performance points and quality improvement points earned) for that performance year or performance year subset.(b)Composite quality score. CMS calculates a composite quality score for each participant hospital for each performance year or performance year subset which equals the sum of the following:(1) The hospital's quality performance points for the hospital-level risk-standardized complication rate following elective primary total hip arthroplasty and/or total knee arthroplasty measure (NQF #1550) described in § 510.400(a)(1) . This measure is weighted at 50 percent of the composite quality score.(2) The hospital's quality performance points for the Hospital Consumer Assessment of Healthcare Providers and Systems Survey measure (NQF #0166) described in § 510.400(a)(2) . This measure is weighted at 40 percent of the composite quality score.(3) Any additional quality improvement points the hospital may earn as a result of demonstrating improvement on either or both of the quality measures in paragraphs (b)(1) and (2) of this section, as described in paragraph (d) of this section.(4) If applicable, 2 additional points for successful THA/TKA voluntary data submission of patient-reported outcomes and limited risk variable data, as described in § 510.400(b) . Successful submission is weighted at 10 percent of the composite quality score.(c)Quality performance points. CMS computes quality performance points for each quality measure based on the participant hospital's performance relative to the distribution of performance of all subsection (d) hospitals that are eligible for payment under IPPS and meet the minimum patient case or survey count for that measure.(1) For the hospital-level risk-standardized complication rate following elective primary total hip arthroplasty and/or total knee arthroplasty measure (NQF #1550) described in § 510.400(a)(1) , CMS assigns the participant hospital measure value to a performance percentile and then quality performance points are assigned based on the following performance percentile scale: (i) 10.00 points for [GREATER THAN EQUAL TO]90th.(ii) 9.25 points for [GREATER THAN EQUAL TO]80th and [LESS THAN]90th.(iii) 8.50 points for [GREATER THAN EQUAL TO]70th and [LESS THAN]80th;(iv) 7.75 points for [GREATER THAN EQUAL TO]60th and [LESS THAN]70th.(v) 7.00 points for [GREATER THAN EQUAL TO]50th and [LESS THAN]60th.(vi) 6.25 points for [GREATER THAN EQUAL TO]40th and [LESS THAN]50th.(vii) 5.50 points for [GREATER THAN EQUAL TO]30th and [LESS THAN]40th.(viii) 0.0 points for [LESS THAN]30th.(2) For the Hospital Consumer Assessment of Healthcare Providers and Systems Survey measure (NQF #0166) described in § 510.400(a)(2) , CMS assigns the participant hospital measure value to a performance percentile and quality performance points are assigned based on the following performance percentile scale:(i) 8.00 points for [GREATER THAN EQUAL TO]90th.(ii) 7.40 points for [GREATER THAN EQUAL TO]80th and [LESS THAN]90th.(iii) 6.80 points for [GREATER THAN EQUAL TO]70th and [LESS THAN]80th.(iv) 6.20 points for [GREATER THAN EQUAL TO]60th and [LESS THAN]70th.(v) 5.60 points for [GREATER THAN EQUAL TO]50th and [LESS THAN]60th.(vi) 5.00 points for [GREATER THAN EQUAL TO]40th and [LESS THAN]50th.(vii) 4.40 points for [GREATER THAN EQUAL TO]30th and [LESS THAN]40th.(viii) 0.0 points for [LESS THAN]30th.(d)Quality improvement points.(1) For performance year 1, if a participant hospital's quality performance percentile on an individual measure described in § 510.400(a) increases from the corresponding time period in the previous year by at least 2 deciles on the performance percentile scale, then the hospitals is eligible to receive quality improvement points equal to 10 percent of the total available point for that individual measure up to a maximum composite quality score of 20 points.(2) For each of performance years 2 through 4, each of performance year subsets 5.1 and 5.2, and each of performance years 6 through 8, if a participant hospital's quality performance percentile on an individual measure described in § 510.400(a) increases from the previous performance year or performance year subset by at least 2 deciles on the performance percentile scale, then the hospital is eligible to receive quality improvement points equal to 10 percent of the total available point for that individual measure up to a maximum composite quality score of 20 points.(e)Exception for hospitals without a measure value. In the case of a participant hospital without a measure value that would allow CMS to assign quality performance points for that quality measure, CMS assigns the 50th percentile quality performance points to the hospital for the individual measure.(1) A participant hospital will not have a measure value for the-(i) Hospital-level risk-standardized complication rate following elective primary total hip arthroplasty and/or total knee arthroplasty measure (NQF #1550) described in § 510.400(a)(1) if the hospital does not meet the minimum 25 case count; or(ii) Hospital Consumer Assessment of Healthcare Providers and Systems Survey measure (NQF #0166) described in § 510.400(a)(2) if the hospital does not meet the minimum of 100 completed survey and does not have 4 consecutive quarters of HCAHPS data.(ii) For either of the measures described in paragraphs (e)(1) or (2) of this section, if CMS identifies an error in the data used to calculate the measure and suppresses the measure value.(f)Quality incentive payments. CMS provides incentive payments to participant hospitals that demonstrate good or excellent quality performance on the composite quality scores described in paragraph (b) of this section. These incentive payments are implemented in the form of the following reductions to the effective discount factors or applicable discount factors described in § 510.300(c) : (1)Performance years 1 through 5. For performance years 1 through 5- (i) A 1.0 percentage point reduction to the effective discount factor or applicable discount factor for participant hospitals with good quality performance, defined as composite quality scores that are greater than or equal to 6.9 and less than or equal to 15.0; or(ii) A 1.5 percentage point reduction to the effective discount factor or applicable discount factor for participant hospitals with excellent quality performance, defined as composite quality scores that are greater than 15.0.(2)Performance years 6 through 8. For performance years 6 through 8- (i) A 1.5-percentage point reduction to the effective discount factor or applicable discount factor for participant hospitals with good quality performance, defined as composite quality scores that are greater than or equal to 6.9 and less than or equal to 15.0; or(ii) A 3-percentage point reduction to the effective discount factor or applicable discount factor for participant hospitals with excellent quality performance, defined as composite quality scores that are greater than 15.0. 80 FR 73540 , Nov. 24, 2015, as amended at 82 FR 615 , Jan. 3, 2017; 85 FR 71201 , Nov. 6, 2020; 86 FR 23573 , May 3, 2021 82 FR 615, 2/18/2017; 85 FR 71201, 11/6/2020; 86 FR 23573, 7/2/2021
