Sltr-haris Type II physl fx lower end of unsp femur, sequela

This code describes a long-term complication or late effect stemming from a Salter-Harris Type II fracture that occurred at the growth plate (physis) of the lower part of an unspecified femur. This type of fracture involves a break through the physis and into the metaphysis, but not into the epiphysis. The "sequela" designation indicates that this code is used to report conditions that are residual effects of the original injury, rather than the acute fracture itself.

Use this code when documenting a patient presenting with a current condition or complication directly attributable to a previously sustained Salter-Harris Type II physeal fracture of the distal femur. Examples include growth arrest, angular deformity, leg length discrepancy, or chronic pain at the fracture site, occurring months or years after the initial injury has healed. This code is appropriate when the acute phase of the fracture has passed and the patient is being treated for the lasting consequences.

• Always assign an additional code to specify the nature of the sequela (e.g., M21.05 for valgus deformity of femur).
• Do not use this code for the initial or subsequent encounter for the acute fracture; use the appropriate acute fracture code.
• Ensure documentation clearly links the current condition to the previous Salter-Harris Type II fracture of the distal femur.
