Long-term Institutionalized Status

Acronym: LTI

CMS identifies whether a Medicare beneficiary is in a long-term institution for both model development and risk score calculation purposes. CMS considers a beneficiary as having long term institutional status if they have been in an institution for 90 days or more. CMS obtains this information from the Minimum Data Set (MDS), which stores dates of 90-day assessments reported by nursing homes.
