Sltr-haris Type IV physeal fx phalanx of left toe, 7thK

This code signifies a complex fracture involving the growth plate (physis) of a phalanx in the left toe, specifically a Salter-Harris Type IV injury. This type of fracture extends through the epiphysis, physis, and metaphysis, carrying a higher risk of growth disturbance. The "subsequent encounter for fracture with nonunion" indicates that the fracture has failed to heal properly after an initial treatment period.

Use this code when documenting follow-up care for a patient with a previously diagnosed Salter-Harris Type IV physeal fracture of the left toe phalanx, where imaging or clinical assessment confirms that the fracture fragments have not united. This applies to ongoing management, such as planning for revision surgery, bone grafting, or continued conservative treatment for the nonunion.

• Ensure documentation clearly specifies "left toe" and "phalanx" to support laterality and anatomical site.
• Verify that the encounter is for subsequent care and that nonunion is explicitly stated or clearly implied in the medical record.
• Distinguish from malunion, which would require a different subsequent encounter code.
