This variable is the total count of months during the year when CCW identified a Medicare claim for a Long-term Care Hospital (LTCH) stay.
Comments
CCW uses a CMS algorithm to identify LTCH: Using the Inpatient Claims File, identify claims where the 3rd and 4th digits of the provider number (source variable called PRVDR_NUM) = 20, 21, 22.
CCW creates 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 long-term care hospital. Note that the number of months with a Medicare SNF claim or a Minimum Data Set (MDS) assessment are captured in the MDCR_SNF_MOS and MDCR_NF_MOS variables, respectively.
Values: 1-12, or null/missing (if no Medicare enrollment)
