Resource Profile: ACH Monthly Event Encounter

This profile contains Required and Must Support data elements for reporting encounter information to the NHSN Acute Care Hospital (ACH) Monthly Digital Quality Measure. This profile is based on the HL7 FHIR® US Core Encounter Profile v3.1.1.

Usages:

• Examples for this Profile: Encounter/encounter-example-ach-monthly-pass1, Encounter/encounter-example-ach-monthly-pass2-emergency, Encounter/encounter-example-ach-monthly-pass2-inpatient, Encounter/encounter-example-ach-monthly-pass3-acute and Encounter/encounter-example-ach-monthly-pass3-short-stay
