When should CPT code 99000 be reported?

CPT code 99000 is specifically used for reporting the services related to the preparation and handling of specimens for laboratory transport. This code is appropriate when a healthcare office collects a specimen—such as blood, urine, or tissue—and packages it for delivery to a laboratory for analysis. The purpose of this code is to account for the additional work involved in preparing specimens, which includes ensuring they are properly labeled, secured, and packaged in a way that meets laboratory requirements.

In contrast, the other options provided relate to different types of services that are not encompassed by CPT 99000. Surgical procedures on lesions have distinct CPT codes that address the specific surgical work being performed. A venipuncture, which is the process of drawing blood from a patient, is also covered by its own specific code that reflects the service rendered. Lastly, administering immunizations involves another set of designated codes that pertain specifically to vaccine administration and related counseling or management. Therefore, the correct application of CPT code 99000 distinctly relates to the preparation of specimens rather than any of the other services described.
