CPT® Code 28020

The procedure described by CPT® Code 28020 refers to an arthrotomy, which is a surgical operation involving the opening of a joint. This specific code pertains to the intertarsal or tarsometatarsal joints, which are located in the foot. The intertarsal joints consist of the articulations between the seven tarsal bones: the talus, calcaneus, cuboid, navicular, and three cuneiform bones. The tarsometatarsal joints are formed where the cuboid and cuneiform bones connect with the metatarsal bones. An arthrotomy may be indicated for various reasons, including the exploration of the joint, drainage of fluid, or removal of loose or foreign bodies that may be causing pain or dysfunction. During the procedure, the surgeon will make an incision to access the joint capsule, which is the protective covering surrounding the joint. Once the joint capsule is exposed, it is opened to allow for direct visualization and intervention. If there is an infection present, the surgeon will drain any accumulated fluid, which may include blood and pus. Cultures may be taken for laboratory analysis to identify any infectious agents. The joint is then thoroughly flushed with saline to clear out debris and any remaining foreign materials. If any foreign bodies are identified, they are carefully removed. After the necessary interventions are completed, the joint may be drained if needed, and the incision is closed in layers to promote proper healing. A dressing is then applied to protect the surgical site. It is important to use the correct CPT® code based on the specific joint being treated, with 28020 designated for intertarsal or tarsometatarsal joints, while other codes are available for different joints in the foot.
