Sltr-haris Type IV physl fx lower end radius, unsp arm, sqla

This code signifies a Salter-Harris Type IV fracture affecting the growth plate at the distal end of the radius, where the fracture line extends through the epiphysis, physis, and metaphysis. The "sequela" indicator specifies that this code is used for complications or conditions arising as a direct result of a previous injury, after the acute phase of healing has passed. The arm affected is not specified.

Use this code when documenting long-term complications such as growth arrest, angular deformity, or chronic pain directly attributable to a previously sustained Salter-Harris Type IV physeal fracture of the distal radius. This code is appropriate for follow-up encounters occurring after the initial fracture has healed, but residual issues persist.

• Always sequence this sequela code after the code for the specific complication being treated (e.g., M21.02 for valgus deformity).
• Ensure documentation clearly links the current condition to the previous Salter-Harris Type IV fracture.
• Do not use this code for the initial acute fracture or for routine follow-up without documented complications.
