S99.821S
ICD-10-CMThis code indicates a long-term or late effect resulting from a previous injury to the right foot, where the specific nature of the injury is not precisely defined by other more specific codes. It signifies that the patient is experiencing ongoing problems directly attributable to an old, resolved trauma to the right foot.
Apply this code when documenting residual symptoms, deformities, or functional limitations in the right foot that are clearly a consequence of a past injury. This is appropriate for conditions like chronic pain, stiffness, or altered gait that persist after the acute phase of the original right foot injury has passed and the injury itself is no longer active.
