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.

| # | 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 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] |

Connects PT and RXN_PT atoms with same CVX Code. Created when an RxNorm editor creates a TTY = RXN_PT atom. |
