CPT® Code 28052

The procedure described by CPT® Code 28052 refers to an arthrotomy with biopsy specifically targeting the metatarsophalangeal joint. The metatarsophalangeal joints are critical articulations located at the base of the toes, where the metatarsal bones connect with the proximal phalanges. This procedure involves a surgical opening of the joint capsule to obtain tissue samples for diagnostic purposes. The term 'arthrotomy' indicates that the joint is surgically accessed, allowing for direct visualization and manipulation of the joint structures. During the procedure, the surgeon carefully dissects the surrounding tissues to expose the joint capsule, which is then incised to facilitate the collection of tissue samples. These samples are essential for laboratory analysis to diagnose various conditions affecting the joint. After the biopsy is completed, the incision is meticulously closed in layers to promote optimal healing, and a dressing is applied to protect the surgical site. It is important to note that this code is specifically used for the metatarsophalangeal joint, distinguishing it from similar procedures performed on other joints, such as the intertarsal or tarsometatarsal joints, which are coded differently.
