To calculate the national prospective 60-day episode payment, CMS uses the following:
(a) Medicare cost data on the most recent audited cost report data available.
(b) Utilization data based on Medicare claims.
(c) An appropriate wage index to adjust for area wage differences.
(d) The most recent projections of increases in costs from the HHA market basket index.
(e) OASIS assessment data and other data that account for the relative resource utilization for different HHA Medicare patient case-mix. An HHA must submit to CMS the OASIS data described at Sec. 484.55(b)(1) and (d)(1) in order for CMS to administer the payment rate methodologies described in Sec. Sec. 484.215, 484.230 and 484.235.
