Sltr-haris Type III physeal fx lower end of l femur, sequela

This code signifies a Salter-Harris Type III fracture affecting the growth plate (physis) at the distal end of the left femur, with the "S" indicating a sequela. This specific fracture type involves a break that extends through the physis and then turns to exit through the epiphysis, affecting both the growth plate and the joint surface.

This code is used when documenting a long-term complication or residual effect directly resulting from a previously sustained Salter-Harris Type III physeal fracture of the lower left femur. Examples include growth disturbance, angular deformity, or chronic pain attributable to the old injury. It should not be used for the initial acute injury.

• Ensure documentation clearly links the current condition as a sequela of the specified fracture.
• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., M21.062 for valgus deformity of left knee).
• Verify laterality (left femur) and fracture type (Salter-Harris Type III) are explicitly stated in the medical record.
