FindingStatus		required	Indicates whether the finding is preliminary, amended, final, etc..
Category	from http://hl7.org/fhir/ValueSet/observation-category (if covered)	0 or more	A class or division of people or things having particular shared characteristics
BodySite		optional	A location or structure in the body, including tissues, regions, cavities, and spaces, for example, right elbow, or left ventricle of the heart.
ChangeFlag		optional	Indicator of significant change (delta) from the last or previous measurement.
Details		optional	An text note containing additional details, explanation, description, comment, or summarization. Details can discuss, support, explain changes to, or dispute information.
Interpretation		optional	A clinical interpretation of a finding.
ObservationQualifier		0 or more	A description of the conditions or context of an observation, for example, under sedation, fasting or post-exercise. Body position and body site are also qualifiers, but handled separately. A qualifier cannot modify the measurement type; for example, a fasting blood sugar is still a blood sugar.
Specimen		optional	Sample for analysis
Device		optional	A specific durable physical device used in diagnosis or treatment. The value is the coding for a type of device, for example, a CPAP machine. The same device might be used on multiple patients.
ReferenceRange		0 or more	The usual or acceptable range for a test result.
Members		required	Members represent the elements of a group of a related but independent observations. Examples are the measurements that compose a complete blood count (CBC), or the elements of a pathology report. Each member is an independent observation, but the grouping reflects a composite lab order, shared specimen, or a single report author. Typically the Category and Reason are not given for individual findings that are part of the panel, but rather given at the level of the panel itself.
Subject		optional	The person or thing that this entry relates to, usually the Person of Record. However, not all entries have health information specifically about the patient, but in different contexts, could refer to a fetus, family member (living or dead), device, location, organization, finding, condition, or intervention.
FocalSubject		optional	For use when FHIR's subject does not allow the desired type of Subject in the Finding.Subject field.
FocalSubjectReference		optional	For use when FHIR's subject does not allow the desired type of Subject in the Finding.Subject field.
FindingMethod		optional	The technique used to create the finding, for example, the specific imaging technical, lab test code, or assessment vehicle.
Evidence		0 or more	A symptom, observation, or other item, for example, a radiology report, that serves as evidence for the current assessment.
RelatedEncounter		optional	If content was generated during a patient encounter, related encounter is the encounter where the information was gained.
Author		optional	The person or organization who created the entry and is responsible for (and may certify) the content.
Informant		optional	The person or entity that provided the information in the entry, as distinct from who created the entry, e.g. the subject (patient), medical professional, family member, device or software program.

WoundTunneling

A discharging blind-ended track that extends from the surface of an organ to an underlying area or abscess cavity. The track is invariably lined with granulation tissue. In chronic cases this may be augmented with epithelial tissue. C0406830

Based On Observation

Value:  CodeableConcept	must be from YesNoUnknownVS		A set of codes drawn from different coding systems, representing the same concept.
ObservationComponent	includes optional ClockDirection includes optional Length	0 or more	A simplified, non-separable observation consisting of a observation code, value (or value absent reason), reference range, and interpretation. The subject of the observation component is the same as in the parent observation.
ValueAbsentReason		optional	Provides a reason why the value of the observation is missing, if it is expected (some observations are not expected to have a value).
ObservationCode		required	A code that represents what the finding concerns, for example, the subject's height, blood pressure, disease status, wound dimensions, diabetes risk, etc. Although named ObservationCode, in different contexts the same attribute might be more naturally referred to as a property, observable, or test code. In assertions (observations without an explicit question), the observation code is defaulted to a value representing 'assertion'.
ClinicallyRelevantTime		optional	The time or time period that the finding addresses. The clinically relevant time is not necessarily when the information is gathered or when a test is carried out, but for example, when a specimen was collected, or the time period referred to by the question. Use a TimePeriod for a measurement or specimen collection continued over a significant period of time (e.g. 24 hour Urine Sodium).

WoundUndermining

Assessment of deep tissue (subcutaneous fat and muscle) damage around the wound margin. Tunneling is just under the skin surface and doesn't involve deep tissue, and sinus tracts are a narrow tract that are away from the wound margins and go downward into the wound.
