CPT® Code 28050

The procedure described by CPT® Code 28050 involves an arthrotomy with biopsy specifically targeting the intertarsal or tarsometatarsal joint. The intertarsal joints consist of the articulations between the seven tarsal bones, which include the talus, calcaneus, cuboid, navicular, and three cuneiform bones. These joints play a crucial role in foot mobility and stability. The tarsometatarsal joints are formed where the cuboid and the three cuneiform bones articulate with the metatarsal bones, connecting the midfoot to the forefoot. This procedure is performed to obtain tissue samples from the joint for diagnostic purposes, which may include evaluating for conditions such as arthritis, infection, or tumors. The surgical approach is determined by the specific joint being biopsied, and it involves careful dissection to expose the joint capsule, which is then opened to allow for the collection of tissue samples. These samples are subsequently sent for laboratory analysis, which is reported separately. The procedure concludes with the closure of the incision in layers and the application of a dressing to promote healing.
