SAS Name
MDCR_NF_MOS
This variable is the total count of months during the year where the beneficiary was in a nursing facility (NF), according to the Minimum Data Set (MDS) assessment. A hierarchical algorithm is used, so that NF is only counted for the month if there is not a Medicare long-term care hospital or skilled nursing facility claim.
CCW creates a Medicare Timeline file to identify the type of facility or level of acuity of care received by the beneficiary each day. Using CMS rules, CCW employs a hierarchy of claims and MDS assessment data. If the beneficiary does not have Medicare claims for inpatient hospitalization, or skilled nursing facility (SNF), then CCW determines if there is an MDS assessment for the day. For MMLEADS, CCW calculates the number of months during the year when the beneficiary was in a NF. Note that the number of months with a Medicare long-term care hospital claim or a SNF claim are captured in the MDCR_LTCH_MOS and MDCR_SNF_MOS variables, respectively.
Values: 1-12, or null/missing (if no Medicare enrollment)
