Sltr-haris Type IV physl fx low end ulna, unsp arm, 7thP

This code signifies a Salter-Harris Type IV fracture affecting the growth plate at the distal end of the ulna. This specific type of physeal fracture involves both the epiphysis and metaphysis, extending through the physis. The "subsequent encounter" indicates ongoing treatment for a fracture that has healed in a misaligned position.

This code is appropriate for follow-up visits where a patient is being managed for a malunited Salter-Harris Type IV fracture of the distal ulna. This includes scenarios such as monitoring the malunion, planning for corrective surgery, or managing complications arising from the malunion. It should be used after the initial treatment of the fracture has concluded and the fracture has healed with an unacceptable degree of angulation or rotation.

• Ensure documentation clearly states "malunion" and specifies the "lower end of ulna" and "Salter-Harris Type IV."
• Verify that the encounter is indeed "subsequent" and not an initial treatment or routine follow-up for a normally healing fracture.
• If the laterality (left or right arm) is documented, use the more specific code that includes laterality.
