4.8.14.0 RXA field definitions

4.8.14.1 Give sub-ID counter (NM) 00342

Definition: Use this field if matching this RXA segment to its corresponding RXG segment. If the two applications are not matching RXG and RXA segments, this field’s value is zero.

4.8.14.2 Administration sub-ID counter (NM) 00344

Definition: This field starts with 1 the first time that medication is administered for this order. Increments by one with each additional administration of medication.

Note: More than one RXA segment can be "matched" to a single RXG segment, as is the case when recording a change of the rate of administration of an IV solution.

4.8.14.3 Date/time start of administration (TS) 00345

Definition: If the order is for a continuous administration (such as an IV), and the rate is changed at a certain time after the start, an RAS message can be issued to record the change. For such an RAS message, this field records the time the rate was changed to the new value recorded in the RXA-12-administered per (time unit) of the same message.

4.8.14.4 Date/time end of administration (if applies) (TS) 00346

Definition: If null, the date/time of RXA-3-date/time start of administration is assumed.

4.8.14.5 Administered code (CE) 00347

Components: <identifier (ST)> ^ <text (ST)> ^ <name of coding system (ST)> ^ <alternate identifier (ST)> ^ <alternate text (ST)> ^ <name of alternate coding system (ST)>

Definition: This field contains the identifier of the medical substance administered. It is equivalent to OBR-4-universal service ID code in function. If the substance administered is a vaccine, CVX codes may be used to code this field (see HL7 table 0292 - Vaccines administered).

4.8.14.6 Administered amount (NM) 00348

Definition: This field contains the amount administered.

4.8.14.7 Administered units (CE) 00349

Components: <identifier (ST)> ^ <text (ST)> ^ <name of coding system (ST)> ^ <alternate identifier (ST)> ^ <alternate text (ST)> ^ <name of alternate coding system (ST)>

Definition: This field is conditional because it is required if the administered amount code does not imply units. This field must be in simple units that reflect the actual quantity of the substance administered. It does not include compound units.

4.8.14.8 Administered dosage form (CE) 00350

Components: <identifier (ST)> ^ <text (ST)> ^ <name of coding system (ST)> ^ <alternate identifier (ST)> ^ <alternate text (ST)> ^ <name of alternate coding system (ST)>

Definition: The dosage form indicates the manner in which the medication is aggregated for dispensing, e.g., tablets, capsules, suppositories. In some cases, this information is implied by the dispense/give code in RXA-5-administered code. Use this field when the administered code does not specify the dosage form.

4.8.14.9 Administration notes (CE) 00351

Components: <identifier (ST)> ^ <text (ST)> ^ <name of coding system (ST)> ^ <alternate identifier (ST)> ^ <alternate text (ST)> ^ <name of alternate coding system (ST)>

Definition: This field contains notes from the provider administering the medication. If coded, requires a user defined table. If free text (describing a custom IV, mixture, or salve, for example) place a null in the first component and the text in the second, e.g., |^this is a free text administration note|.

4.8.14.10 Administering provider (XCN) 00352

Components: <ID number (ST)> ^ <family name (ST)> ^ <given name (ST)> ^ <middle initial or name (ST)> ^ <suffix (e.g., JR or III) (ST)> ^ <prefix (e.g., DR) (ST)> ^ <degree (e.g., MD) (ST)> ^ <source table (IS)> ^ <assigning authority (HD)> ^ <name type code(ID)> ^ <identifier check digit (ST)> ^ <code identifying the check digit scheme employed (ID )> ^ <identifier type code (IS)> ^ <assigning facility (HD)>

Subcomponents of assigning authority: <namespace ID (IS)> & <universal ID (ST)> & <universal ID type (ID)

Subcomponents of assigning facility: <namespace ID (IS)> & <universal ID (ST)> & <universal ID type (ID)

Definition: This field contains the provider ID of the person administering the pharmaceutical.

4.8.14.11 Administered at location (CM) 00353

Components: <point of care (IS)> & <room (IS) ^ <bed (IS)> & <facility (HD) & <location status (IS) & <patient location type (IS)> & <building (IS)> & <floor (IS)> ^ < street address (ST)> & <other designation (ST)> & <city (ST)> & <state or province (ST)> & <zip or postal code (ST)> & <country (ID)> & <address type (ID)> & <other geographic designation (ST)>

Definition: The first component contains the inpatient or outpatient location at which the drug or treatment was administered (if applicable). The default (null) value is the current census location for the patient. Site specific table. This first component has the same form as PV1-3-assigned patient location.

The second component can be used to specify an address. This could be used to fill mail orders to a patient or provider, or to account for home health care.

4.8.14.12 Administered per (time unit) (ST) 00354

Definition: This field contains the rate at which this medication was administered as calculated by using RXA-6-administered amount and RXA-7-administered units. This field is conditional because it is required when a treatment is administered continuously at a prescribed rate, e.g., certain IV solutions.

4.8.14.13 Administered strength (NM) 01134

Definition: Use when RXA-5-administered code does not specify the strength. This is the numeric part of the strength, used in combination with RXA-14-administered strength unit.

4.8.14.14 Administered strength unit (CE) 01135

Components: <identifier (ST)> ^ <text (ST)> ^ <name of coding system (ST)> ^ <alternate identifier (ST)> ^ <alternate text (ST)> ^ <name of alternate coding system (ST)>

Definition: Use when RXA-5-administered code does not specify the strength. This is the unit of the strength, used in combination with RXA-13-administered strength.

Note: These units can be a "compound quantity"; i.e., the units may express a quantity per unit of time. For example, micrograms per hour (ug/h) is an acceptable value. These compound units are contained in the ISO+ table. See Chapter 7 for full definition of ISO+ units.

4.8.14.15 Substance lot number (ST) 01129

Definition: This field contains the lot number of the medical substance administered.

Note: The lot number is the number printed on the label attached to the container holding the substance and on the packaging which houses the container. If the substance is a vaccine, for example, and a diluent is required, a lot number may appear on the vial containing the diluent; however, any such identifier associated with a diluent is not the identifier of interest. The substance lot number should be reported, not that of the diluent.

4.8.14.16 Substance expiration date (TS) 01130

Definition: This field contains the expiration date of the medical substance administered.

Note: Vaccine expiration date does not always have a "day" component; therefore, such a date may be transmitted as YYYYMM.

4.8.14.17 Substance manufacturer (CE) 01131

Components: <identifier (ST)> ^ <text (ST)> ^ <name of coding system (ST)> ^ <alternate identifier (ST)> ^ <alternate text (ST)> ^ <name of alternate coding system (ST)>

Definition: This field contains the manufacturer of the medical substance administered.

Note: For vaccines, code system MVX may be used to code this field (see Section 4.10, "VACCINE ADMINISTRATION DATA"). This field may be used if the manufacturer of the substance is not identified by the code used in RXA-5 Administered Code.

4.8.14.18 Substance refusal reason (CE) 01136

Components: <identifier (ST)> ^ <text (ST)> ^ <name of coding system (ST)> ^ <alternate identifier (ST)> ^ <alternate text (ST)> ^ <name of alternate coding system (ST)>

Definition: This field contains the reason the patient refused the medical substance. Any entry in the field indicates that the patient did not take the substance.

4.8.14.19 Indication (CE) 01123

Components: <identifier (ST)> ^ <text (ST)> ^ <name of coding system (ST)> ^ <alternate identifier (ST)> ^ <alternate text (ST)> ^ <name of alternate coding system (ST)>

Definition: This field contains the identifier of the condition or problem for which the drug/treatment was prescribed. May repeat if multiple indications are relevant.

4.8.14.20 Completion status (ID) 01223

Definition: Status of treatment administration event. Refer to HL7 table 0322 - Completion status for valid values.
