S99.191P
ICD-10-CMOther physeal fracture of right metatarsal, subsequent encounter for fracture with malunion
This code signifies a fracture affecting the growth plate (physis) of a metatarsal bone in the right foot, excluding those specifically classified as Salter-Harris types. The fracture is currently in a healing phase, but the bone segments have united in an anatomically incorrect or misaligned position. This malunion can lead to functional impairment and pain.
Use this code for follow-up encounters where a patient is being treated for a right metatarsal physeal fracture that has healed with malunion. This applies when the malunion is the primary focus of the encounter, such as for evaluation of symptoms related to the malunion or planning for corrective procedures. It should be used after the initial treatment of the acute fracture.
