CPT® Code 36400

Venipuncture, younger than age 3 years, necessitating the skill of a physician or other qualified health care professional, not to be used for routine venipuncture; femoral or jugular vein

The CPT® Code 36400 refers to the procedure of venipuncture performed on patients younger than 3 years of age, which requires the specialized skills of a physician or another qualified healthcare professional. This code is specifically designated for instances where routine venipuncture is not applicable, particularly when accessing more challenging veins such as the femoral or jugular vein. In infants and young children, common sites for venipuncture include the scalp, external jugular, femoral, saphenous, dorsal veins of the hand, or the dorsal arch of the foot. The procedure necessitates careful consideration of the site selection, ensuring that the most appropriate vein is chosen based on the individual patient's anatomy and condition. Prior to the procedure, it is essential to document the circumstances that require the expertise of a qualified professional and to obtain the necessary consent from the parent or guardian. The selected site must be prepared to ensure sterile entry, and once the vein is punctured, blood samples are collected for laboratory studies that can be reported separately. It is important to note that this code should not be used for routine venipuncture, as it is specifically intended for more complex cases involving younger patients.
