Source Synopsis

Authority
HL7 Table 0292, Vaccine Administered (CVX) is a product of the National Center of Immunization and Respiratory Diseases (NCIRD). NCIRD is part of the Centers for Disease Control and Prevention (CDC).

The NCIRD developed and maintains CVX.

Purpose
CVX is a HL7 standard code set. The codes are used for immunization messages with either HL7 2.3.1 or HL7 2.5.1.

Description
CVX includes approximately 200 active and inactive vaccine terms for the United States (US). It also indicates a vaccine’s current availability and the last update time for the vaccine code. Inactive vaccine codes allow users to transmit historical immunization data.

Update Frequency
CVX is updated daily.

RxNorm Update Frequency
CVX is updated in each RxNorm monthly release.

Summary of Changes

There are no changes since the last monthly release.

Source Provided Files:

The CVX drug data is available from: http://www2a.cdc.gov/vaccines/iis/iisstandards/vaccines.asp?rpt=cvx

The two NDC files are available from: https://www2a.cdc.gov/vaccines/iis/iisstandards/ndc_tableaccess.asp

The following three files are used for RxNorm source processing.

# CVX Field Name Description RxNorm Representation
1 CVX Code Indicates the product used in a vaccination. There are three codes indicating that the concept is not a vaccine: 998 = "no vaccine administered", 999 = "unknown vaccine or immune globulin", and 99 = "RESERVED - do not use". RXNCONSO.CODE
2 CVX Short Description Vaccine short name RXNCONSO.STR (TTY = AB)
3 Full Vaccine Name Vaccine full name RXNCONSO.STR (TTY = PT)
4 Note More information about the vaccine RXNSAT.ATN = SOS
5 VaccineStatus Indicates if the vaccine is currently available in the United States RXNSAT.ATN = VACCINE_STATUS
6 internalID Not applicable Not applicable
7 nonvaccine A value of "True" indicates that the concept is a non-vaccine. There are three concepts with nonvaccine = "True," indicating that the concept is not a vaccine: "no vaccine administered", "unknown vaccine or immune globulin", and "RESERVED - do not use". All other concepts have a nonvaccine value of "False". RXNSAT.ATN = NON_VACCINE
8 update_date Indicates the last time this particular vaccine code was updated in this file RXNSAT.ATN = DATE_LAST_MODIFIED

RxNorm Representation

This section lists RxNorm data elements and traces them back to the specific CVX data that populates them.

Summary of Changes

There are no changes since the last monthly release.

Source Provided Files:

File Name Description
web_cvx.xlsx Excel file containing information on both active and inactive vaccines available in the US
NDC_Unit_Use.xlsx Excel file containing NDC unit of use information facilitating the use of NDCs to identify vaccines
NDC_Unit_Sale.xlsx Excel file containing NDC unit sale information facilitating the use of NDCs to identify vaccines

RxNorm Identifiers:

Identifiers are assigned as follows:

Identifier Origin
CODE CVX Code
SAUI Not applicable
SCUI Not applicable
SCUI Not applicable

Atoms (RXNCONSO):

Term Type Origin
PT CODE = web_cvx.xlsx.CVX Code
STR = web_cvx.xlsx.Full Vaccine Name
AB CODE = web_cvx.xlsx.CVX Code
STR = web_cvx.xlsx.CVX Short Description
RXN_PT (RxNorm editor created atom) CODE = Same code as PT
STR = RxNorm editor created name (for a given NDC); brand name appended using NDC_Unit_Sale.xlsx.OuterPropName and NDC_Unit_Use.xlsx.UseUnitPropName

If a source atom has more than one NDC and the NDCs have different meanings, new RXN_PT atoms are created by an RxNorm editor to separate the NDCs which can then be associated with proper RxNorm forms. The original atom remains a TTY = PT atom.

For example,
PT atom string:
hepatitis A vaccine, adult dosage

RXN_PT atom strings:
hepatitis A vaccine, adult dosage vial [HAVRIX]
hepatitis A vaccine, adult dosage syringe [HAVRIX]
hepatitis A vaccine, adult dosage vial [VAQTA]
hepatitis A vaccine, adult dosage syringe [VAQTA]

Attributes (RXNSAT):

ATN Origin
DATE_LAST_MODIFIED web_cvx.xlsx.update_date
SOS web_cvx.xlsx.Note
VACCINE_STATUS web_cvx.xlsx.VaccineStatus
NON_VACCINE web_cvx.xlsx.nonvaccine
NDC NDC_Unit_Use.xlsx.NDC11 and NDC_Unit_Sale.xlsx.NDC11
(assigned to TTY = RXN_PT atoms only; TTY = PT atoms lack NDCs)

Relationships (RXNREL):

REL RELA/Inverse RELA Description
RO (RxNorm editor created relationship) mapped_to
mapped_from
Connects PT and RXN_PT atoms with same CVX Code. Created when an RxNorm editor creates a TTY = RXN_PT atom.
