CPT® Code 90705

Deleted

The CPT® Code 90705 refers to the measles virus vaccine, which is a live vaccine administered subcutaneously. Vaccines, unlike immune globulins that provide short-term, passive immunity, are designed to elicit an active immune response. This is achieved by introducing altered versions of specific viruses or bacteria into the body, prompting the immune system to produce its own antibodies. The primary goal of vaccination is to establish long-term immunity, allowing the body to "remember" how to produce these antibodies upon subsequent exposure to the same pathogen. The measles vaccine specifically contains an attenuated, or weakened, form of the measles virus. This attenuation ensures that while the vaccine can stimulate an immune response and antibody production, it does not possess the virulence necessary to cause the disease itself. The measles vaccine is part of a broader category of live virus vaccines, which also includes those for mumps and rubella. Each of these vaccines is administered subcutaneously, and they are reported using specific CPT® codes. For instance, code 90704 is designated for the mumps vaccine, 90705 for the measles vaccine, and 90706 for the rubella vaccine. Additionally, there are combination vaccines such as the MMR (measles, mumps, rubella) vaccine, reported under code 90707, and the MMRV (measles, mumps, rubella, and varicella) vaccine, reported under code 90710. It is important to note that these codes specifically report the vaccine product used, rather than the administration or any associated services.
