This element describes the type of condition this observation is referring to.

The element if present points to the text describing the problem being recorded; including any dates, comments, et cetera. The contains a URI in value attribute. This URI points to the free text description of the problem in the document that is being described.

When used it shall refer to the narrative, typically #{label}-{generated-id}, e.g. #xxx-1

A clinical document normally records only those condition observation events that have been completed, not observations that are in any other state. Therefore, the shall always have code='completed'.

The effectiveTime, also referred to as the “biologically relevant time” is the time at which the observation holds for the patient. For a provider seeing a patient in the clinic today, observing a history of heart attack that occurred five years ago, the effectiveTime is five years ago.

The <low> and <high> values should be no more precise than known, but as precise as possible.

The effectiveTime/low (a.k.a. "onset date".html) asserts when the condition became biologically active.

The effectiveTime/high (a.k.a. "resolution date".html) asserts when the condition e became biologically resolved. If the date of resolution is not known, then effectiveTime/high will be present with a nullFlavor of "UNK".If this condition is known to be resolved, then the effectiveTime/high would be present.

The <value> is the condition that was found. It may a coded or an un-coded string, but its type is always coded. The coded form shall be used also to indicate known absent conditions or the nonavailability of information about them.

The <originalText> element within the <code> element described above is used as follows: the <value> contains a <reference> to the <originalText> in order to link the coded value to the problem narrative text (minus any dates, comments, et cetera.html). The <reference> contains a URI in value attribute. This URI points to the free text description of the problem in the document that is being described.

The URI given in the value attribute of the element points to an element in the narrative content that contains the complete text describing the medication. In a CDA document, the URI given in the value attribute of the element points to an element in the narrative content that contains the complete text describing the medication.

The translation element may be used to transmit a set of other concept descriptors, using for example ICD-10 or other international or jurisdictional code systems.

When valued in an instance, this attribute signals the imposition of a set of template-defined constraints. The value of this attribute provides a unique identifier for the templates in question

If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.

A human readable name or mnemonic for the assigning authority. The Assigning Authority Name has no computational value. The purpose of a Assigning Authority Name is to assist an unaided human interpreter of an II value to interpret the authority. Note: no automated processing must depend on the assigning authority name to be present in any form.

Specifies if the identifier is intended for human display and data entry (displayable = true) as opposed to pure machine interoperation (displayable = false).

A unique identifier that guarantees the global uniqueness of the instance identifier. The root alone may be the entire instance identifier.

A character string as a unique identifier within the scope of the identifier root.

This element describes the type of condition this observation is referring to.

The element if present points to the text describing the problem being recorded; including any dates, comments, et cetera. The contains a URI in value attribute. This URI points to the free text description of the problem in the document that is being described.

If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.

For character-based encoding types, this property specifies the character set and character encoding used. The charset shall be identified by an Internet Assigned Numbers Authority (IANA) Charset Registration [] in accordance with RFC 2978 [].

Indicates whether the raw byte data is compressed, and what compression algorithm was used.

The integrity check is a short binary value representing a cryptographically strong checksum that is calculated over the binary data. The purpose of this property, when communicated with a reference is for anyone to validate later whether the reference still resolved to the same data that the reference resolved to when the encapsulated data value with reference was created.

Specifies the algorithm used to compute the integrityCheck value. The cryptographically strong checksum algorithm Secure Hash Algorithm-1 (SHA-1) is currently the industry standard. It has superseded the MD5 algorithm only a couple of years ago, when certain flaws in the security of MD5 were discovered. Currently the SHA-1 hash algorithm is the default choice for the integrity check algorithm. Note that SHA-256 is also entering widespread usage.

For character based information the language property specifies the human language of the text.

Identifies the type of the encapsulated data and identifies a method to interpret or render the data.

Data that is primarily intended for human interpretation or for further machine processing is outside the scope of HL7. This includes unformatted or formatted written language, multimedia data, or structured information as defined by a different standard (e.g., XML-signatures.)

A telecommunication address (TEL), such as a URL for HTTP or FTP, which will resolve to precisely the same binary data that could as well have been provided as inline data.

If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.

When used it shall refer to the narrative, typically #{label}-{generated-id}, e.g. #xxx-1

Specifies the periods of time during which the telecommunication address can be used. For a telephone number, this can indicate the time of day in which the party can be reached on that telephone. For a web address, it may specify a time range in which the web content is promised to be available under the given address.

One or more codes advising a system or user which telecommunication address in a set of like addresses to select for a given telecommunication need.

An abbreviated rendition of the full data. A thumbnail requires significantly fewer resources than the full data, while still maintaining some distinctive similarity with the full data. A thumbnail is typically used with by-reference encapsulated data. It allows a user to select data more efficiently before actually downloading through the reference.

A clinical document normally records only those condition observation events that have been completed, not observations that are in any other state. Therefore, the shall always have code='completed'.

If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.

The plain code symbol defined by the code system. For example, "784.0" is the code symbol of the ICD-9 code "784.0" for headache.

Specifies the code system that defines the code.

The common name of the coding system.

If applicable, a version descriptor defined specifically for the given code system.

A name or title for the code, under which the sending system shows the code value to its users.

The valueSet extension adds an attribute for elements with a CD dataType which indicates the particular value set constraining the coded concept.

The valueSetVersion extension adds an attribute for elements with a CD dataType which indicates the version of the particular value set constraining the coded concept.

The text or phrase used as the basis for the coding.

Specifies additional codes that increase the specificity of the the primary code.

A set of other concept descriptors that translate this concept descriptor into other code systems.

The effectiveTime, also referred to as the “biologically relevant time” is the time at which the observation holds for the patient. For a provider seeing a patient in the clinic today, observing a history of heart attack that occurred five years ago, the effectiveTime is five years ago.

The <low> and <high> values should be no more precise than known, but as precise as possible.

If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.

A quantity specifying a point on the axis of natural time. A point in time is most often represented as a calendar expression.

Specifies whether the limit is included in the interval (interval is closed) or excluded from the interval (interval is open).

A code specifying whether the set component is included (union) or excluded (set-difference) from the set, or other set operations with the current set component and the set as constructed from the representation stream up to the current point.

The effectiveTime/low (a.k.a. "onset date".html) asserts when the condition became biologically active.

The effectiveTime/high (a.k.a. "resolution date".html) asserts when the condition e became biologically resolved. If the date of resolution is not known, then effectiveTime/high will be present with a nullFlavor of "UNK".If this condition is known to be resolved, then the effectiveTime/high would be present.

The difference between high and low boundary. The purpose of distinguishing a width property is to handle all cases of incomplete information symmetrically. In any interval representation only two of the three properties high, low, and width need to be stated and the third can be derived.

The arithmetic mean of the interval (low plus high divided by 2). The purpose of distinguishing the center as a semantic property is for conversions of intervals from and to point values.

The <value> is the condition that was found. It may a coded or an un-coded string, but its type is always coded. The coded form shall be used also to indicate known absent conditions or the nonavailability of information about them.

Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
