ICD-10-CMSalter-Harris Type II physeal fracture of phalanx of left toe, subsequent encounter for fracture with nonunion
This code signifies a specific type of growth plate fracture affecting a toe bone in the left foot, where the fracture line extends through the growth plate and then exits into the metaphysis. The "subsequent encounter" indicates the patient is receiving routine care during the healing phase, and "nonunion" specifies that the bone fragments have failed to heal together after a reasonable period.
Use this code for follow-up visits where a patient is being managed for a previously diagnosed Salter-Harris Type II fracture of a left toe phalanx that has not healed. This includes scenarios where the physician is assessing the nonunion, planning further intervention, or providing ongoing conservative management for the unhealed fracture.
