In simple words: This code represents a late effect (sequela) of a displaced fracture of the growth plate at the bottom of the thigh bone. The growth plate is the area of developing bone near the knee joint. It doesn't specify whether the original injury was to the right or left thigh bone.

Displaced fracture of the lower epiphysis (separation) of an unspecified femur, sequela. This code describes a condition resulting from a previous displaced fracture of the growth plate located at the lower end of the femur (thigh bone). It is used when the affected femur (right or left) is not specified.

Example 1: A patient presents with a leg length discrepancy and limited knee range of motion years after sustaining a fracture of the lower femoral epiphysis as a child. The original fracture was displaced. The affected side is not specified in the current encounter., A young adult experiences chronic knee pain and instability following a childhood injury where they suffered a displaced fracture of the lower growth plate of their femur. The current physician does not specify which leg was affected in the childhood injury., A patient has ongoing difficulty with weight-bearing activities due to a previous displaced fracture of the lower femoral epiphysis, which happened several years prior. The current documentation does not specify which femur was affected.

Documentation should clearly indicate the presence of a sequela (late effect) resulting from the original displaced fracture. Details of the original injury, including imaging reports, should support the diagnosis. Any current symptoms or functional limitations related to the sequela should also be documented.

** The code specifically refers to sequelae (long-term effects). Do not use this code to describe the acute fracture. This code should not be used if the specific side (right or left) of the original fracture is known.
