Source Synopsis

Web site:
http://www2a.cdc.gov/vaccines/iis/iisstandards/vaccines.asp?rpt=cvx

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 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 RxNorm intermittently and occurs when new CVX content represented in RxNorm becomes available.

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]

Data Examples with Sample Database Queries

This section lists source terminology specific data examples and sample database queries using Structured Query Language (SQL) to obtain the data. For more information about RxNorm data and files, see the RxNorm Technical Documentation.

Names and Codes in RXNCONSO.RRF

Here are sample source terminology code, source string, RxNorm Concept Unique Identifier (RXCUI), RxNorm string, RxNorm term type (TTY), and suppress values.

SOURCE_CODE SOURCE_STR RXCUI RXNORM_STR RXNORM_TTY SUPPRESS
12 diphtheria antitoxin 3510 Diphtheria Antitoxin IN N
12 diphtheria antitoxin 3510 diphtheria immunoglobulin SY N

Here is a sample database query to retrieve the data above:

SELECT distinct rc1.code as source_code, rc1.str as source_str, rc1.rxcui, rc2.str as rxnorm_str, rc2.tty as rxnorm_tty, rc2.suppress
FROM rxnconso rc1, rxnconso rc2
WHERE rc1.code in ('12')
     AND rc1.sab = 'CVX'
     AND rc1.rxcui = rc2.rxcui
     AND rc2.sab = 'RXNORM';
