ICD-10-CMOther physeal fracture of phalanx of unspecified toe, initial encounter for open fracture
This code signifies an open fracture involving the growth plate (physis) of a phalanx in an unspecified toe, excluding the great toe. An open fracture indicates that the skin and soft tissue overlying the fracture site have been compromised, exposing the bone. This is the initial encounter for treatment of this specific injury.
This code is appropriate for documenting the initial treatment of a patient presenting with a growth plate fracture of any phalanx in a toe other than the hallux, where there is an associated open wound. This would include scenarios such as a crush injury or direct trauma to the toe resulting in both a physeal fracture and a skin laceration communicating with the fracture.
