ICD-10-CMSalter-Harris Type II physeal fracture of phalanx of right toe, subsequent encounter for fracture with nonunion
This code signifies a specific type of growth plate fracture (Salter-Harris Type II) affecting a toe bone in the right foot, where the fracture is not healing as expected (nonunion). It indicates that the patient is in a later stage of care for this particular injury, beyond the initial treatment.
This code is appropriate for follow-up encounters when a patient with a previously diagnosed Salter-Harris Type II fracture of a right toe phalanx is presenting with evidence of nonunion. This could include visits for ongoing management, evaluation of healing progress, or planning for further intervention due to the lack of bone fusion.
