CPT® Code 87001

Deleted

The CPT® Code 87001 refers to the procedure of inoculating a small animal with infected tissue, followed by a period of observation to study the effects of the infection. This process is typically conducted in a controlled environment where the animal's response to the infection can be monitored closely. The term "inoculation" refers to the introduction of pathogens or infected tissue into the animal's body to assess how the organism reacts to the infection. The observation phase is crucial as it allows researchers or veterinarians to gather data on the progression of the infection, the animal's immune response, and any clinical signs that may develop as a result. It is important to note that if the animal is subsequently dissected for further examination, the appropriate code to use would be CPT® Code 87003, which specifically addresses the dissection of the animal following inoculation.
