Closed fracture of unspecified part of neck of femur

This code signifies a break in the femoral neck, the narrow region connecting the femoral head to the shaft, where the precise location of the fracture within the neck is not specified. It represents a closed injury, meaning the skin remains intact over the fracture site. This type of fracture often compromises blood supply to the femoral head, increasing the risk of avascular necrosis.

Apply this code when documentation confirms a closed fracture of the femoral neck, but lacks specificity regarding the subcapital, transcervical, or basicervical location. This is appropriate when the physician's notes or imaging reports simply state "femoral neck fracture" without further anatomical detail.

• Avoid using this code if the documentation specifies the exact location within the femoral neck (e.g., subcapital, transcervical, basicervical); more specific codes exist.
• Ensure the fracture is explicitly documented as "closed." If an open fracture is present, a different code from the 820 series would be appropriate.
• Always review the entire medical record for laterality (left or right) and any associated complications, which may require additional coding.
