CMS Pub. 100-16, ch. 5, § 30.2.1
HOS-Modified
The HOS-Modified (HOS-M) is a shorter, modified version of the Medicare HOS and
contains 6 ADL items as the core items used to calculate an annual frailty adjustment
factor for PACE organizations. The survey also includes 12 physical and mental health
status questions from the VR-12. The HOS–M survey is cross–sectional, measuring
the physical and mental health functioning of beneficiaries at a single point in time.
HOS-M reporting requirements specify that all PACE organizations with a Medicare
contract in effect on or before January 1st of the previous year and a minimum enrollment
of 30 report the HOS-M for current year reporting.
Similar to the HOS, the HOS-M design is based on a randomly selected sample of 1,200
individuals from each participating PACE Organization. All eligible members are
included in the sample for plans with populations of less than 1,200.
The survey protocols for the HOS and HOS-M data collection efforts are similar. The
HOS and HOS-M technical specifications are updated annually by NCQA and published
each February in HEDIS® Volume 6: Specifications for the Medicare Health Outcomes
Survey. Additional information is available from NCQA’s web site at
http://www.ncqa.org under HEDIS® and Quality Measurement.
