Sltr-haris Type IV physl fx low end rad, unsp arm, 7thK

This code indicates a specific type of growth plate fracture (Salter-Harris Type IV) affecting the lower end of the radius, where the fracture has failed to heal properly (nonunion). It signifies that the patient is receiving ongoing care for this unhealed fracture, rather than initial treatment. The "unspecified arm" component means the laterality of the injury is not documented.

Apply this code when a patient presents for follow-up care, such as cast changes, physical therapy, or surgical planning, for a previously diagnosed Salter-Harris Type IV fracture of the distal radius that has not united. This code is appropriate for subsequent encounters after the initial treatment phase, specifically when nonunion has been identified.

• Ensure documentation clearly states "nonunion" and that the encounter is for ongoing management of the unhealed fracture.
• Verify the fracture type is specifically Salter-Harris Type IV and located at the lower end of the radius.
• Only use this code if the laterality (left or right arm) is not specified in the medical record. If known, a more specific code should be used.
