ICD-10-CMSalter-Harris Type III physeal fracture of phalanx of unspecified toe, initial encounter for closed fracture
This code signifies a specific growth plate fracture affecting the phalanx (bone segment) of an unidentifiable toe. It's a Salter-Harris Type III injury, meaning the fracture line extends through the growth plate and then turns to exit through the epiphysis (end of the bone). This type of fracture can impact future bone growth.
Apply this code when documentation confirms a Salter-Harris Type III fracture of a toe phalanx, but the specific toe (e.g., great toe, second toe) is not specified. This code is appropriate for the initial treatment encounter of a closed fracture, meaning the skin remains intact over the injury site.
