The Milliman Long-Term Care Guidelines (Guidelines) are a set of comprehensive benchmark morbidity assumptions that can be used for a variety of purposes. The Guidelines include separate assumptions for claim incidence, disabled life mortality, claim recovery, and transfers, and are customizable to reflect either a starting situs or current situs definition of claim.

Milliman devotes significant resources to the research and development of the Guidelines, which are updated on a regular basis. There have been nine editions of the Guidelines, starting with the 1992 Guidelines, up through the most recent edition of the 2023 Guidelines. The 2023 Guidelines are based primarily on claims from 2010 through 2019, with consideration for experience during the COVID-19 pandemic in 2020 and 2021. The final product is based on observed data and incorporates the collective judgment of Milliman LTC actuaries on the future level of morbidity.

Each update of the Guidelines considers recent claim data, along with past analysis and research. The 2023 Guidelines dataset includes roughly 460,000 claims and 30 million life years of exposure during the primary study period, and represents experience from 18 of the top 25 LTC insurers (based on lives in-force). The inception-to-date Guidelines dataset includes over 1.1 million claims and 82 million life years of exposure. In addition to the insured data analyzed, other research and industry studies are considered and have an indirect influence on the Guidelines.
