Nondisp fx of base of nk of l femr, 7thK

This code signifies a patient's follow-up visit for a left femoral neck fracture, specifically at the base of the neck, which was initially treated without surgical intervention (nondisplaced, closed). The key clinical finding for this encounter is the presence of nonunion, meaning the bone fragments have failed to heal together adequately.

Use this code for subsequent encounters when a patient with a previously diagnosed and treated nondisplaced closed fracture of the base of the left femoral neck presents with evidence of nonunion. This would typically involve follow-up imaging (e.g., X-rays) and clinical assessment confirming the lack of healing.

• Ensure documentation clearly specifies "nonunion" for the closed fracture.
• Verify the laterality (left femur) and the specific fracture site (base of neck).
• This "K" seventh character indicates a subsequent encounter for a closed fracture with nonunion; do not use for initial treatment or routine follow-up without nonunion.
