An action that is or was performed on or for a patient. This can be a physical intervention like an operation, or less invasive like long term services, counseling, or hypnotherapy.

Business identifiers assigned to this procedure by the performer or other systems which remain constant as the resource is updated and is propagated from server to server.

Allows identification of the procedure as it is known by various participating systems and in a way that remains consistent across servers.

This is a business identifier, not a resource identifier (see discussion). It is best practice for the identifier to only appear on a single resource instance, however business practices may occasionally dictate that multiple resource instances with the same identifier can exist - possibly even with different resource types. For example, multiple Patient and Person resource instances might share the same social insurance number.

The URL pointing to a FHIR-defined protocol, guideline, order set or other definition that is adhered to in whole or in part by this Procedure.

The URL pointing to an externally maintained protocol, guideline, order set or other definition that is adhered to in whole or in part by this Procedure.

This might be an HTML page, PDF, etc. or could just be a non-resolvable URI identifier.

A reference to a resource that contains details of the request for this procedure.

A larger event of which this particular procedure is a component or step.

The MedicationAdministration resource has a partOf reference to Procedure, but this is not a circular reference. For example, the anesthesia MedicationAdministration is part of the surgical Procedure (MedicationAdministration.partOf = Procedure). For example, the procedure to insert the IV port for an IV medication administration is part of the medication administration (Procedure.partOf = MedicationAdministration).

A code specifying the state of the procedure. Generally, this will be the in-progress or completed state.

The "unknown" code is not to be used to convey other statuses. The "unknown" code should be used when one of the statuses applies, but the authoring system doesn't know the current state of the procedure.

This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid.

Captures the reason for the current state of the procedure.

This is generally only used for "exception" statuses such as "not-done", "suspended" or "aborted". The reason for performing the event at all is captured in reasonCode, not here.

A code that classifies the procedure for searching, sorting and display purposes (e.g. "Surgical Procedure").

The specific procedure that is performed. Use text if the exact nature of the procedure cannot be coded (e.g. "Laparoscopic Appendectomy").

0..1 to account for primarily narrative only resources.

The person, animal or group on which the procedure was performed.

The Encounter during which this Procedure was created or performed or to which the creation of this record is tightly associated.

This will typically be the encounter the event occurred within, but some activities may be initiated prior to or after the official completion of an encounter but still be tied to the context of the encounter.

Estimated or actual date, date-time, period, or age when the procedure did occur or is occurring. Allows a period to support complex procedures that span more than one date, and also allows for the length of the procedure to be captured.

This indicates when the procedure actually occurred or is occurring, not when it was asked/requested/ordered to occur. For the latter, look at the occurence element of the Request this Procedure is "basedOn". The status code allows differentiation of whether the timing reflects a historic event or an ongoing event. Ongoing events should not include an upper bound in the Period or Timing.bounds.

Age is generally used when the patient reports an age at which the procedure was performed. Range is generally used when the patient reports an age range when the procedure was performed, such as sometime between 20-25 years old. dateTime supports a range of precision due to some procedures being reported as past procedures that might not have millisecond precision while other procedures performed and documented during the encounter might have more precise UTC timestamps with timezone.

The date the occurrence of the procedure was first captured in the record regardless of Procedure.status (potentially after the occurrence of the event).

Individual who recorded the record and takes responsibility for its content.

Indicates if this record was captured as a secondary 'reported' record rather than as an original primary source-of-truth record. It may also indicate the source of the report.

Reported data may have different rules on editing and may be visually distinguished from primary data.

Limited to "real" people rather than equipment.

Distinguishes the type of involvement of the performer in the procedure. For example, surgeon, anaesthetist, endoscopist.

Allows disambiguation of the types of involvement of different performers.

Indicates who or what performed the procedure.

A reference to Device supports use cases, such as pacemakers.

The organization the device or practitioner was acting on behalf of.

Practitioners and Devices can be associated with multiple organizations. This element indicates which organization they were acting on behalf of when performing the action.

The location where the procedure actually happened. E.g. a newborn at home, a tracheostomy at a restaurant.

Ties a procedure to where the records are likely kept.

The coded reason or reference why the procedure was performed. This may be a coded entity of some type, or may simply be present as text, or may be a reference to one of several resources that justify the procedure.

Use Procedure.reason.concept when a code sufficiently describes the reason. Use Procedure.reason.reference when referencing a resource, which allows more information to be conveyed, such as onset date. Procedure.reason.concept and Procedure.reason.reference are not meant to be duplicative. For a single reason, either Procedure.reason.concept or Procedure.reason.reference can be used. Procedure.reason.concept may be a summary code, or Procedure.reason.reference may be used to reference a very precise definition of the reason using Condition | Observation | Procedure | DiagnosticReport | DocumentReference. Both Procedure.reason.concept and Procedure.reason.reference can be used if they are describing different reasons for the procedure.

Detailed and structured anatomical location information. Multiple locations are allowed - e.g. multiple punch biopsies of a lesion.

If the use case requires attributes from the BodySite resource (e.g. to identify and track separately) then use the standard extension procedure-targetbodystructure.

The outcome of the procedure - did it resolve the reasons for the procedure being performed?

If outcome contains narrative text only, it can be captured using the CodeableConcept.text.

This could be a histology result, pathology report, surgical report, etc.

There could potentially be multiple reports - e.g. if this was a procedure which took multiple biopsies resulting in a number of anatomical pathology reports.

Any complications that occurred during the procedure, or in the immediate post-performance period. These are generally tracked separately from the notes, which will typically describe the procedure itself rather than any 'post procedure' issues.

If complications are only expressed by the narrative text, they can be captured using the CodeableConcept.text.

Any complications that occurred during the procedure, or in the immediate post-performance period.

This is used to document a condition that is a result of the procedure, not the condition that was the reason for the procedure.

If the procedure required specific follow up - e.g. removal of sutures. The follow up may be represented as a simple note or could potentially be more complex, in which case the CarePlan resource can be used.

Any other notes and comments about the procedure.

A device that is implanted, removed or otherwise manipulated (calibration, battery replacement, fitting a prosthesis, attaching a wound-vac, etc.) as a focal portion of the Procedure.

The kind of change that happened to the device during the procedure.

The device that was manipulated (changed) during the procedure.

Identifies medications, devices and any other substance used as part of the procedure.

Used for tracking contamination, etc.

For devices actually implanted or removed, use Procedure.device.
