CPT® Code 0901T

The procedure described by CPT® Code 0901T involves the placement of a bone marrow sampling port, which is a specialized device used to facilitate the extraction of bone marrow fluid and tissue. Bone marrow sampling is typically performed on the posterior superior iliac crest, which is the upper part of the hip bone located at the back. This site is preferred due to its accessibility and the absence of major blood vessels or nerves, minimizing the risk of complications. However, bone marrow samples can also be obtained from alternative sites such as the front of the iliac crest, the humerus (the upper arm bone), the calcaneus (the heel bone), or the tibia (the shin bone). The ideal specimen for bone marrow analysis includes both a liquid aspirate, which is the fluid component, and a solid sample that contains the bone and marrow. The procedure begins with the administration of a local anesthetic to numb the area at the sampling site after it has been properly marked and cleansed to reduce the risk of infection. A small incision is made to allow for the insertion of a special hollow needle, which is guided through the bone, often with imaging assistance to ensure accuracy. A syringe attached to this needle is then used to aspirate a small volume of bone marrow liquid. Following this, a larger needle is employed to obtain a biopsy sample, which consists of a small piece of bone along with the marrow. After the samples are collected, the needle is withdrawn, pressure is applied to the site to control any bleeding, and the area is subsequently bandaged to promote healing.
