Sltr-haris Type III physl fx low end ulna, unsp arm, 7thD

This code describes a specific type of growth plate fracture (Salter-Harris Type III) at the lower end of the ulna bone. This particular injury involves a fracture line that extends through the growth plate and into the joint surface, occurring in an unspecified arm. The "D" suffix indicates that this is a subsequent encounter for a fracture that is healing routinely.

Use this code when a patient presents for follow-up care of a previously diagnosed Salter-Harris Type III fracture of the distal ulna. This applies when the fracture is progressing as expected without complications, such as during cast changes, wound checks, or routine radiographic evaluations during the healing phase.

• Ensure documentation specifies "subsequent encounter" and "routine healing" for the "D" suffix.
• Verify the fracture type is explicitly Salter-Harris Type III and located at the lower end of the ulna.
• Do not use for initial treatment or for encounters with delayed healing, nonunion, or malunion.
