PhdImplementationGuide 0.3.0 - STU 1 (2nd ballot)

This page is part of the Personal Health Device FHIR IG (v0.3.0: STU 1 Ballot 3) based on FHIR R4. The current version which supercedes this version is 1.0.0. For a full list of available versions, see the Directory of published versions

ASN1 BITs Codes

The ASN1 to HL7 code system is the result of mapping 11073 20601 BITs measurements or values to codes. HL7 (in V2, V3, and FHIR) has no native support for BITs type values.

The following tables gives the codes, names, and event or state type for the currently specified BITs measurements and values. The HL7 ASN1 Code is the code entered into the FHIR code elements. The ASN1 name is standardized and is analogous to the reference identifier for the nomenclature codes. If the state type is an event, only the ‘set’ meaning is displayed.

MDS and other Non-Measurement Attributes

MDS Power Status Attribute

Partition:Term Code: 1:2389 32-bit value 67925

Reference identifier: MDC_ATTR_POWER_STAT

Mder Bit HL7 ASN1 Code ASN1 name meaning when set meaning when cleared event or state

MDS Regulation Status from the Reg-Cert-Data-List Attribute

Partition:Term Code: 8:8066 32-bit code 532354

Alert Operational Status Attribute

This attribute is a metric descriptive attribute; it is not a measurement but an extra piece of information saying something about a measurement.

Enumeration Measurements

The following tables give the currently defined BITs measurements. These values are defined in the 11073 104xx specialization standards. The HL7 ASN1 codes for these and future values can be derived directly from the protocol exchange.
