Complete transverse atyp femoral fracture, left leg, sequela

This code signifies a complete fracture of the femur that extends across the bone, specifically on the left leg, and is considered atypical. It indicates that the fracture is a long-term complication or late effect of an initial injury or condition, rather than an acute event. This type of fracture is often associated with prolonged use of certain medications, such as bisphosphonates.

Apply this code when documentation clearly states a complete, transverse, atypical femoral fracture of the left leg, and the encounter is for the management of a sequela. This includes follow-up care, treatment of nonunion or malunion, or addressing chronic pain directly resulting from the previous fracture. Documentation must specify "sequela" or indicate a late effect.

• Ensure the documentation explicitly identifies the fracture as "atypical" and "complete transverse" to differentiate from other femoral fractures.
• Verify the laterality is "left leg" as specified by the 5th character.
• The 7th character "S" indicates sequela; do not use for initial or subsequent encounters for active treatment.
