Which of the following is considered a tubular body part?

• A. Trachea
• B. Small Intestine
• C. Liver
• D. Blood vessel

Answer: (C)

The correct answer is the blood vessel, as it is classified as a tubular body part according to the ICD-10-PCS coding guidelines. Tubular body parts are structures in the body that have a hollow, tubular shape, allowing for the passage of substances. Blood vessels, which include arteries and veins, fall into this category due to their role in transporting blood throughout the circulatory system. In contrast, while the trachea and small intestine might also be considered tubular in a general sense, the correct classification in this particular context is focused on how the ICD-10-PCS system defines these structures. The liver does not fit into the tubular classification as it is a solid organ rather than a hollow structure designed to convey substances through a central lumen.
