S99.199P
ICD-10-CMOther physeal fracture of unspecified metatarsal, subsequent encounter for fracture with malunion
This code signifies a fracture affecting the growth plate (physis) of an unidentifiable metatarsal bone in the foot. The patient is in a subsequent phase of care, and the fracture has healed improperly, resulting in a malunion.
Apply this code when documenting follow-up care for a patient who previously sustained a physeal fracture of a metatarsal, and imaging or clinical assessment confirms that the bone has healed in an abnormal alignment. This would be used for ongoing management of the malunion, such as planning for corrective surgery or managing residual symptoms.
