Sltr-haris Type III physl fx upper end rad, unsp arm, sqla

This code describes a chronic or late effect of a Salter-Harris Type III fracture affecting the growth plate (physis) at the upper end of the radius. This specific fracture type involves a break that extends through the physis and then longitudinally through the epiphysis, but not into the joint. The "sequela" designation indicates that this code is used for conditions arising as a direct result of the initial injury, even after the acute phase has passed.

Use this code when documenting long-term complications or residual effects stemming from a Salter-Harris Type III physeal fracture of the proximal radius. This includes conditions like growth arrest, angular deformity, limb length discrepancy, or chronic pain directly attributable to the original injury. It is appropriate for follow-up visits addressing these persistent issues.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., M21.02 for valgus deformity).
• Ensure documentation clearly links the current condition to the previous Salter-Harris Type III fracture of the radial physis.
• Verify that the "unspecified arm" designation is appropriate; if the laterality is known, a more specific code should be used.
