This code system http://hl7.org/fhir/us/cdmh/CodeSystem/pcornet-encounter-type-codes defines the following codes:

Code | Display | Definition
AV | Ambulatory Visit | Includes visits at outpatient clinics, physician offices, same day/ambulatory surgery centers, urgent care facilities, and other same-day ambulatory hospital encounters, but excludes emergency department encounters.
ED | Emergency Department | Includes ED encounters that become inpatient stays (in which case inpatient stays would be a separate encounter). Excludes urgent care facility visits. ED claims should be pulled before hospitalization claims to ensure that ED with subsequent admission won't be rolled up in the hospital event. Does not include observation stays, where known.
EI | Emergency Department Admit to Inpatient Hospital Stay (permissible substitution) | Permissible substitution for preferred state of separate ED and IP records. Only for use with data sources where the individual records for ED and IP cannot be distinguished.
IP | Inpatient Hospital Stay | Includes all inpatient stays, including: same-day hospital discharges, hospital transfers, and acute hospital care where the discharge is after the admission date. Does not include observation stays, where known.
IS | Non-Acute Institutional Stay | Includes hospice, skilled nursing facility (SNF), rehab center, nursing home, residential, overnight non-hospital dialysis, and other non-hospital stays.
OS | Observation Stay | Hospital outpatient services given to help the doctor decide if the patient needs to be admitted as an inpatient or can be discharged. Observations services may be given in the emergency department or another area of the hospital.” Definition from Medicare, CMS Product No. 11435, https://www.medicare.gov/Pubs/pdf/11435.pdf.
IC | Institutional Professional Consult (permissible substitution) | Permissible substitution when services provided by a medical professional cannot be combined with the given encounter record, such as a specialist consult in an inpatient setting; this situation can be common with claims data sources. This includes physician consults for patients during inpatient encounters that are not directly related to the cause of the admission (e.g. a ophthalmologist consult for a patient with diabetic ketoacidosis) (guidance updated in v4.0).
TH | Telehealth | Includes telemedicine or virtual visits, which can be conducted via video, phone or other means.
OA | Other Ambulatory Visit | PIncludes other non-overnight AV encounters such as hospice visits, home health visits, skilled nursing visits, other non-hospital visits, as well as telemedicine, telephone and email consultations. May also include 'lab only' visits (when a lab is ordered outside of a patient visit), 'pharmacy only' (e.g., when a patient has a refill ordered without a face-to-face visit), 'imaging only', etc.
NI | No information | Patient Encounter Type has No information.
UN | Unknown | Patient Encounter Type is Unknown.
OT | Other | Patient Encounter Type is Other.
