Encounter subject


Support to Advance Encounter Subject

  • The PACIO (Post-Acute Care Interoperability) Project, established February 2019, is a collaborative effort between industry, government, and other stakeholders, with the goal of establishing a framework for the development of FHIR implementation guides to facilitate health information exchange.
  • The PACIO Community has published a Re-Assessment Timepoints FHIR implementation guide ( that profiles the US Core Encounter to support the representation of subsets of the longer encounters such as those found in post-acute care, behavioral health, and other residential settings. Because they represent parts of the larger encounter that is already a data class within USCDI, we believe that field-level requirements within that guide provide anecdotal support to proposed encounter data elements, including status, subject, identifier, participant, and reason for encounter. By providing real-world experience from implementations of the standard, we hope the Re-Assessment Timepoints implementation guide will help motivate the inclusion of these Encounter data elements within a future version of USCDI.
  • The PACIO Community also believes that the concept of an encounter subset that is at the core of the Re-Assessment Timepoints implementation guide is a useful data element to include within USCDI and we will propose this as a new data element.

MedMorph submitted multiple…

MedMorph submitted multiple elements for the Encounter class that were modeled directly from the mustSupport elements of the US Core Encounter profile. What has been proposed in USCDI does not reflect the same structure and we believe will cause difficulty by those using the US Core structure. It has been noted that several elements of an Encounter Participant (e.g., role, NPI, name, etc.) are found in the Care Team Member class, but what information would be exchanged using the USCDI Encounter Participant element? We have been told that the Encounter Participant NPI is found in Care Team Member.Provider NPI. Is the Encounter Participant element simply a link or reference to the Care Team Member class? If so, that needs to be defined/explained in USCDI.
