Sltr-haris Type IV physl fx low end r tibia, 7thK

This code signifies a complex growth plate fracture (Salter-Harris Type IV) affecting the lower end of the right shin bone, where the fracture line extends through both the growth plate and a portion of the bone's shaft. "Nonunion" indicates that the fracture has failed to heal completely after the expected healing period. This diagnosis is made during a follow-up visit for ongoing management of the unhealed fracture.

Use this code for subsequent encounters when a patient is being treated for a Salter-Harris Type IV fracture of the distal right tibia that has not healed. This applies to situations where the patient is receiving further treatment, such as cast changes, physical therapy, or surgical planning, specifically due to the nonunion. It should be assigned after the initial treatment phase has concluded and the fracture continues to show no signs of bony bridging.

• Ensure documentation clearly states "nonunion" and specifies the Salter-Harris Type IV classification for the distal right tibia.
• Verify that the encounter is for ongoing management of the nonunion, not for initial treatment or routine follow-up of a healing fracture.
• Always sequence this code as a primary diagnosis when the nonunion is the focus of the encounter.
