eLTSS FHIR Reference Implementation Guide - Altarum Institute

The eLTSS (Electronic Long-Term Services and Supports) initiative is a CMS-ONC partnership. Pilots in the initiative will facilitate the development of basic elements for eventual inclusion in electronic standards. These standards will enable the creation, exchange and re-use of interoperable service plans by beneficiaries, community-based long-term services and supports providers, payers, health care providers and the individuals they serve. Altarum Institute is a nonprofit research and consulting organization that creates and implements solutions to advance health among vulnerable and publicly insured populations. Altarum Institute developed an eLTSS FHIR reference implementation guide to provide a testing ground for applications to request eLTSS compliant data or to validate eLTSS compliant FHIR bundles.
