CPT Codes Mapped to CVX Codes

This table cross-references Current Procedural Terminology (CPT^TM) codes that are related to vaccines, toxoids and immune globulins with their corresponding CVX codes. The goal of the table is to support mapping of CPT codes to CVX codes in systems that receive CPT codes as part of an electronic data exchange. The CVX and/or NDC code systems are highly recommended when exchanging immunization data, but if a sending system must use CPT codes, this table may be used by the receiving system to translate the CPT code to the single best CVX code equivalent. In all cases, the code utilized, be it NDC, CVX or CPT, should be the most specific and granular representation possible of the vaccine given. Where only a single vaccine exists, the CPT code is mapped to that vaccine specific CVX code. However, in many cases, a single CPT code could be used with multiple vaccines utilizing different CVX codes. In this situation, the CPT code is mapped to the "unspecified formulation" CVX code because it is not possible to infer a specific vaccine formulation from the CPT code alone.
This table is not intended to support mapping from CVX to CPT nor to be a definitive source for CPT codes. Practices must approach billing for vaccines (selection of a CPT code for a given administration) independently from recording and reporting the most specific vaccine codes to an IIS or other clinical trading partner. Active CPT codes, inactive CPT codes and pre-release CPT codes are included. Every effort is made to keep the codes current.
