RXE - Pharmacy/Treatment Encoded Order Segment

The RXE segment details the pharmacy or treatment application's encoding of the order. It also contains several pharmacy-specific order status fields, such as RXE-16-number of refills remaining, RXE-17-number of refills/doses dispensed, RXE-18-D/T of most recent refill or dose dispensed, and RXE-19-total daily dose.

Note that ORC-7-quantity/timing has a different meaning from RXE-1-quantity/timing and RXG-3-quantity/timing. The pharmacy or treatment department has the "authority" (and/or necessity) to schedule dispense/give events. Hence, the pharmacy or treatment department has the responsibility to encode this scheduling information in RXE-1-quantity/timing and RXG-3-quantity/timing. ORC-7-quantity/timing does not change: it always specifies the requested give/dispense schedule of the original order.

RXE-1: Quantity/Timing

(Definition from ORC.7 in Ch. 4)

Attention: The ORC-7 field was retained for backward compatibility only as of v 2.5 and the detail was withdrawn and removed from the standard as of v 2.7. The reader is referred to the TQ1 and TQ2 segments described in sections 4.5.4 and 4.5.5, respectively.

(Definition from OBR.27 in Ch. 4)

Attention: The OBR-27 element was retained for backward compatibility only as of v 2.5 and the detail was withdrawn and removed from the standard as of v 2.7.

(Definition from RXE.1 in Ch. 4A)

Attention: The RXE-1 field was retained for backward compatibilty only as of v 2.5 and the detail was withdrawn and removed from the standard as of v 2.7.

(Definition from RXG.3 in Ch. 4A)

Attention: The RXG-3 field was retained for backward compatibilty only as of v 2.5 and the detail was withdrawn and removed from the standard as of v 2.7.

Note: The contents of fields 3-8 should be identical to the comparable fields in the RXE (RXE-2 thru 5).


(Definition from OBR.27 in Ch. 7)

Attention: The OBR-27 element was retained for backward compatibility only as of v 2.5 and the detail was withdrawn and removed from the standard as of v 2.7.

RXE-2: Give Code (CWE) 00317

(Definition from RXE.2 in Ch. 4A)

Definition: This field identifies the medical substance or treatment that has been ordered to be given to the patient, as encoded by the pharmacy or treatment supplier; it is equivalent to OBR-4-universal service ID in function. In the RXE segment, this give code must be fully encoded. The dispense fields, which define the units and amount of what is to be issued to the patient (see RXE-10-dispense amount and RXE-11-dispense units below) do not necessarily correlate with the instructions of what amount is to be "given" or administered with each dose, and may or may not be specified with the order. For example, the "give" part of the order may convey the field-representation of give 250 mg of Ampicillin, while the request to dispense part of the order may convey issue 30 tablets of generic equivalent for this outpatient prescription.

The coding system used is conditional on both the nature of the medical substance or treatment ordered and site-specific implementation considerations. For vaccines, HL7 Table 0292 – Vaccines Administered is the preferred coding system. For non-vaccine products, the coding system may be a local implementation of User-defined Table 0479 – Pharmaceutical Substances or an external coding system. Examples of external coding systems include, but are not limited to, National Drug Codes (NDC), Medispan Generic Product Identifier (MGPI), Drug Descriptor Identifier (DDID), and other drug codes listed in HL7 Table 0396 – Coding Systems. The following examples illustrate some code tables other than User-defined Table 0479:

NDC:                0006915404^Norvasc 10mg Tabs^NDC

DDID:                015189^Norvasc 10mg Tabs^DDID

CVX (HL70292):            30^HBIG^CVX

(Definition from RXG.4 in Ch. 4A)

Definition: This field is the identifier of the medical substance/treatment ordered to be given to the patient; it is equivalent to OBR-4-Universal service ID in function. See the RXE segment for a complete definition of the RXE-2-Give code. If the substance given is a vaccine, CVX codes may be used to code this field (see HL7 Table 0292 - Vaccines administered in Chapter 2C, Code Tables).

RXE-3: Give Amount - Minimum (NM) 00318

(Definition from RXE.3 in Ch. 4A)

Definition: This field contains the ordered amount as encoded by the pharmacy or treatment supplier. In a variable dose order, this is the minimum ordered amount. In a non-varying dose order, this is the exact amount of the order.

Note:    This field is not a duplication of the first component of the quantity/timing field, since in non-pharmacy/treatment orders, that component can be used to specify multiples of an ordered amount.

Another way to say this is that, for pharmacy/treatment orders, the quantity component of the quantity/timing field refers to what is to be given out at each service interval; thus, in terms of the RX order, that first component always defaults to 1. Hence, in the actual execution of the order, the value of 1 in the first component of the quantity/timing field always refers to one administration of the amount specified in this field (the requested Give Amount field).


(Definition from RXG.5 in Ch. 4A)

Definition: This field contains the ordered amount as encoded by the pharmacy/treatment supplier. In a variable dose order, this is the minimum ordered amount. In a non-varying dose order, this is the exact amount of the order.

Note: This field is not a duplication of the first component of the quantity/timing field, since in non-pharmacy/treatment orders, that component can be used to specify multiples of an ordered amount.

Another way to say this is that, for pharmacy/treatment orders, the quantity component of the quantity/timing field refers to what is to be given out at each service interval; and thus, in terms of the RX order, that first component always defaults to 1. Hence, in the actual execution of the order, the value of 1 in the first component of the quantity/timing field always refers to one administration of the amount specified in this field (the requested Give Amount field).


RXE-4: Give Amount - Maximum (NM) 00319

(Definition from RXE.4 in Ch. 4A)

Definition: In a variable dose order, this is the maximum ordered amount. In a non-varying dose, this field is not used.

(Definition from RXG.6 in Ch. 4A)

Definition: In a variable dose order, this is the maximum ordered amount. In a non-varying dose order, this field is not used.

RXE-5: Give Units (CWE) 00320

(Definition from RXE.5 in Ch. 4A)

Definition: This field contains the units for the give amount as encoded by the pharmacy or treatment (e.g., respiratory therapy) application. Refer to Table 0715 - Give Units in Chapter 2C for valid values.

Note: These units can be a "compound quantity"; i.e., the units may contain the word "per." For example, micrograms per KG (micg/kg) is an acceptable value, which means that the units are micrograms per KG (of body weight).


A table of standard units that contains compound units is needed. Until such a table is agreed on, a user-defined table is needed for each site.

(Definition from RXG.7 in Ch. 4A)

Definition: This field contains the units for the give amount. Refer to Table 0735 - Give Units in Chapter 2C for valid values.

Note: These units can be a "compound quantity;" i.e., the units may contain the word "per." For example, micrograms per KG (micg/kg) is an acceptable value, which means that the units are micrograms per KG (of body weight).


A table of standard units that contains compound units is needed. Until such a table is agreed on, a user-defined table is needed for each site.

RXE-6: Give Dosage Form (CWE) 00321

(Definition from RXE.6 in Ch. 4A)

Definition: The dosage form indicates the manner in which the medication or treatment is aggregated for dispensing, e.g., tablets, capsules, suppositories. In some cases, this information is implied by the give code in RXE-2-Give Code. Use the RXE-6-Give Dosage Form when the give code does not specify the dosage form. Refer to Table 0716 - Give Dosage Form in Chapter 2C for valid values.

(Definition from RXG.8 in Ch. 4A)

Definition: The dosage form indicates the manner in which the medication/treatment is aggregated for dispensing, e.g., tablets, capsules, suppositories. In some cases, this information is implied by the give code in RXG-4-Give Code. Use this field when the give code does not specify the dosage form. Refer to Table 0736 - Give Dosage Form in Chapter 2C for valid values.

RXE-7: Provider's Administration Instructions (CWE) 00298

(Definition from RXO.7 in Ch. 4A)

Definition: This field identifies the ordering provider's instructions to the patient or to the provider administering the drug or treatment. If coded, a user-defined table must be used. If transmitted as free text, place a null in the first component and the text in the second, e.g., |^this is a free text administration instruction|.Refer to Table 0752 - Provider's Administration Instructions in Chapter 2C for valid values.

(Definition from RXE.7 in Ch. 4A)

Definition: This field contains the ordering provider's instructions to the patient or the provider administering the drug or treatment. If coded, a user-defined table must be used; if free text (describing a custom IV, mixture, or salve, for example), place the text in the second component, e.g., |^this is a free text administration instruction|.Refer to Table 0718 - Provider's Administration Instructions in Chapter 2C for valid values.

RXE-8: Deliver-To Location

(Definition from RXO.8 in Ch. 4A)

Attention: The RXO-8 field was retained for backward compatibilty only as of v 2.6 and the detail was withdrawn and removed from the standard as of v 2.8.

(Definition from RXE.8 in Ch. 4A)

Attention: The RXE-8 field was retained for backward compatibilty only as of v 2.5 and the detail was withdrawn and removed from the standard as of v 2.7.

RXE-9: Substitution Status (ID) 00322

(Definition from RXE.9 in Ch. 4A)

Definition: Refer to HL7 Table 0167 - Substitution Status in Chapter 2C, Code Tables, for valid values. If a substitution has been made, and a record of the original requested give code (RXO-1-requested give code) is needed, the optional RXO segment can be included in the RDE message.

(Definition from RXD.11 in Ch. 4A)

Definition: Refer to HL7 Table 0167 - Substitution Status in Chapter 2C, Code Tables, for suggested values.

(Definition from RXG.10 in Ch. 4A)

Definition: Refer to HL7 Table 0167 - Substitution Status in Chapter 2C, Code Tables, for valid values.

Note: The next two fields are equivalent to the corresponding fields of the RXE segment. They are included (optionally) in the RXG so that it may "stand alone" as a "give" instruction segment.


RXE-10: Dispense Amount (NM) 00323

Definition: This field contains the amount to be dispensed as encoded by the pharmacy or treatment supplier.

RXE-11: Dispense Units (CWE) 00324

(Definition from RXE.12 in Ch. 4A)

Definition: This field contains the total original number of refills. Outpatient only.

RXE-13: Ordering Provider's DEA Number (XCN) 00305

(Definition from RXO.14 in Ch. 4A)

Attention: This field was retained for backward compatibilty only as of v 2.7 and the detail was withdrawn and removed from the standard as of v 2.9. The reader is referred to the PRT segment described in Chapter 7.

(Definition from RXE.13 in Ch. 4A)

Definition: This field is retained for backward compatibility only as of v 27. The reader is referred to the PRT segment described in Chapter 7.

This field is defined as conditional because it is required when the substance requested is a controlled substance (e.g., a narcotic). If the person referenced in this field is also referenced in PRT segment, they must contain the same information. However, if there is a difference, then PRT segment takes precedence.

RXE-14: Pharmacist/Treatment Supplier's Verifier ID (XCN) 00306

(Definition from RXO.15 in Ch. 4A)

Definition: This field is the provider ID of the pharmacist/treatment supplier verifier. Use if required by the pharmacy or treatment application or site on orders (or some subgroup of orders), in addition to ORC-11-verified by.

Example:    

The site requires a "verified by" provider (such as a nurse) and a "verifying pharmacist/treatment supplier" on the order. In this case the first field, ORC-11-verified by, is already present; but the second field, RXO-15-pharmacist/treatment supplier's verifier ID, is needed.

(Definition from RXE.14 in Ch. 4A)

Definition: This field is retained for backward compatibility only as of v 27. The reader is referred to the PRT segment described in chapter 7.

This field contains the provider ID of Pharmacist/treatment supplier's verifier. Use if required by the pharmacy or treatment application or site on orders (or some subgroup of orders). If the person referenced in this field is also referenced in PRT segment, they must contain the same information. However, if there is a difference, then PRT segment takes precedence.

(Definition from RXE.15 in Ch. 4A)

Definition: This field contains the prescription number as assigned by the pharmacy or treatment application. Equivalent in uniqueness to the pharmacy/treatment filler order number. At some sites, this may be the pharmacy or treatment system (internal) sequential form. At other sites, this may be an external form. This is a required field in RXE when used in pharmacy/treatment messages, but it is not required when used in product experience messages (see Chapter 7).

(Definition from RXD.7 in Ch. 4A)

Definition: This field is equivalent in uniqueness to the pharmacy/treatment supplier filler order number. At some sites, this may be the pharmacy/treatment supplier (internal) sequential form. At other sites, this may be an external number.

(Definition from FT1.42 in Ch. 6)

Definition: This field contains the prescription number as assigned by the pharmacy or treatment application. Equivalent in uniqueness to the pharmacy/treatment filler order number. At some sites, this may be the pharmacy or treatment system (internal) sequential form. At other sites, this may be an external form.

RXE-16: Number of Refills Remaining (NM) 00326

Definition: This field contains the total daily dose being dispensed as expressed in terms of the actual dispense units.

Note:    The next two fields are equivalent to the corresponding fields of the RXE segment. They are included (optionally) in the RXD so that it may "stand alone" as a dispense result instruction segment.


RXE-20: Needs Human Review (ID) 00307

(Definition from RXO.16 in Ch. 4A)

Definition: This field uses HL7 Table 0136 - Yes/No Indicator in Chapter 2C, Code Tables. The values have the following meaning for this field:

Y    Yes - Indicates that the pharmacist or non-pharmacist treatment supplier filling the order needs to pay special attention to the text in the RXO-6-provider's pharmacy/treatment instructions. A warning is present.

N    No - No warning is present. This is the equivalent default (null) value.

An example of the use of this field is given by the following case:

A smart Order Entry application knows of a possible drug or treatment interaction on a certain order, but the provider issuing the order wants to override the condition. In this case, the pharmacy or treatment application receiving the order will want to have a staff pharmacist or non-pharmacist treatment supplier review the interaction and contact the ordering physician.

(Definition from RXE.20 in Ch. 4A)

Definition: This field uses HL7 Table 0136 - Yes/No Indicator in Chapter 2C, Code Tables. The values have the following meaning for this field:

Y    Yes - Indicates that a warning is present. The application receiving the encoded order needs to warn the person administering the drug or treatment to pay attention to the text in RXE-21-pharmacy/treatment special dispensing instructions.

N    No - Indicates no warning is present. This is the equivalent default (null) value.

(Definition from RXD.14 in Ch. 4A)

Definition: Refer to HL7 Table 0136 - Yes/no indicator for valid values. The values have the following meaning for this field:

Y    Yes - Indicates that a warning is present. The application receiving the dispense order needs to warn the person dispensing/administering the drug or treatment to pay attention to the text in RXD-15-Special dispensing instructions.

N    No - Indicates no warning is present. This is the equivalent default (null) value.

(Definition from RXG.12 in Ch. 4A)

Definition: Refer to HL7 Table 0136 - Yes/No Indicator for valid values. The values have the following meaning for this field:

Y    Yes - Indicates that a warning is present. The application receiving the dispense order needs to warn the person dispensing/administering the drug or treatment to pay attention to the text in RXG-13-Special administration instructions.

N    No - Indicates no warning is present. This is the equivalent default (null) value.

RXE-21: Special Dispensing Instructions (CWE) 00330

(Definition from RXE.21 in Ch. 4A)

Definition: This field contains the pharmacy or treatment supplier's provider-generated special instructions to the provider dispensing/administering the order. Refer to Table 0721 - Special Dispensing Instructions in Chapter 2C for valid values.

(Definition from RXD.15 in Ch. 4A)

Definition: This field contains the amount (number) of substance/treatment to be administered.

RXE-24: Give Rate Units (CWE) 00333

(Definition from RXE.24 in Ch. 4A)

Definition: This field contains the units for RXE-23-give rate amount. May be composite. The ratio of the RXE-23-give rate amount and RXE-24-give rate units defines the actual rate of administration. Thus, if RXE-23-give rate amount = 100 and RXE-24-give rate units = ml/hr, the requested rate of administration is 100 ml/hr. (See ISO+ figure 7-9 in Chapter 7 for possible compound units codes.) Refer to Table 0722 - Give Rate Units in Chapter 2C for valid values.

(Definition from RXG.16 in Ch. 4A)

Definition: This field contains the units for RXG-15-give rate amount. May be composite. The ratio of the RXG-15-give rate amount and RXG-16-give rate units fields define the actual rate of administration. Thus, if RXG-15-give rate amount = 100 and RXG-16-give rate units = ml/hr, the requested rate of administration is 100 ml/hr. Refer to Table 0740 - Give Rate Units in Chapter 2C for valid values.

RXE-25: Give Strength (NM) 01126

(Definition from RXE.25 in Ch. 4A)

Definition: Use when RXE-2-give code does not specify the strength. This is the numeric part of the strength, used in combination with RXE-26-give strength units.

(Definition from RXG.17 in Ch. 4A)

Definition: Use when RXG-4-Give code does not specify the strength. This is the numeric part of the strength, used in combination with RXG-18-Give strength units.

RXE-26: Give Strength Units (CWE) 01127

(Definition from RXE.26 in Ch. 4A)

Definition: Use when RXE-2-Give Code does not specify the strength. This is the unit of the strength, used in combination with RXE-25-Give Strength. Refer to Table 0723 - Give Strength Units in Chapter 2C for valid values.

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 (micg/h) is an acceptable value. These compound units are contained in the ISO+ table. See Chapter 7 for full definition of ISO+ units.


(Definition from RXG.18 in Ch. 4A)

Definition: Use when RXG-4-Give Code does not specify the strength. This is the unit of the strength, used in combination with RXG-17-Give Strength. Refer to Table 0741 - Give Strength Units in Chapter 2C for valid values.

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 (micg/h) is an acceptable value. These compound units are contained in the ISO+ table. See Chapter 7 for full definition of ISO+ units.


RXE-27: Give Indication (CWE) 01128

Definition: This field identifies the condition or problem for which the drug/treatment was prescribed. May repeat if multiple indications are relevant. Refer to Table 0724 - Give Indication in Chapter 2C for valid values.
