Code D2394 covers filling a back tooth with tooth-colored composite material when four or more surfaces need restoration, typically following extensive decay or damage. Patients commonly receive this procedure after large cavities affect multiple sides of a posterior tooth. This code generally has higher reimbursement rates than simpler fillings due to the additional surfaces and complexity involved.
