Official Description

Lyme disease vaccine, adult dosage, for intramuscular use

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 90665 refers to the Lyme disease vaccine specifically formulated for adult dosage and intended for intramuscular administration. Vaccines, unlike immune globulins, are designed to provide active, long-term immunity. This is achieved by introducing altered versions of specific pathogens, such as viruses or bacteria, into the body. The immune system responds by producing its own antibodies, which are crucial for defending against future infections by the same pathogen. In the case of Lyme disease, the causative agent is the bacterium Borrelia burgdorferi, which is primarily transmitted through the bite of infected ticks. Lyme disease can lead to serious complications if left untreated, potentially affecting the heart, joints, and nervous system. The use of this vaccine is essential in preventing the onset of Lyme disease by equipping the immune system to recognize and combat the bacterium effectively. It is important to note that this code specifically reports the vaccine product used, rather than the administration or any associated services.
