In simple words: This code describes a patient who has a broken left thigh bone near the hip, where the bone pieces are separated. The break happened in the past, it did not break the skin, and it has not healed properly.

A displaced midcervical fracture of the left femur (thigh bone) is a break that goes through the middle part of the femoral neck. In this specific scenario, the broken pieces of bone are separated and do not meet. This is a subsequent encounter, meaning the patient has been seen for this injury before. The fracture is closed, meaning it didn't break the skin, and it has not healed correctly (nonunion).

Example 1: A patient is seen for follow-up after a car accident where they sustained a closed, displaced midcervical fracture of the left femur. The bone has not united, and the patient is experiencing pain and limited mobility., An elderly patient fell at home several weeks ago and suffered a displaced midcervical fracture of the left femur. They are being seen today and imaging reveals nonunion at the fracture site., A patient was treated for a closed, displaced midcervical fracture of the left femur months ago. Today they are being seen for persistent pain and during the encounter, imaging studies show that the fracture has failed to unite.

Documentation should include details of the original injury, subsequent treatments, imaging studies confirming the displaced nature of the fracture and the nonunion status, and the patient's current symptoms.
