Nondisp fx of greater trochanter of r femr, 7thN

This code describes a situation where a patient has a non-displaced fracture of the greater trochanter on their right femur, and they are receiving ongoing care for a complication where the bone is failing to heal (nonunion). This specific nonunion is associated with an initial open fracture that was severe, classified as type IIIA, IIIB, or IIIC.

Use this code for follow-up encounters when a patient with a previously diagnosed nondisplaced greater trochanteric fracture of the right femur is being treated for a nonunion. The original injury must have been an open fracture of a severe type (IIIA, IIIB, or IIIC). This code is appropriate for subsequent visits related to the nonunion management, such as cast changes, wound care, or evaluation for further surgical intervention.

• Ensure documentation clearly specifies "nonunion" as the reason for the subsequent encounter.
• Verify the original fracture was an open fracture, specifically type IIIA, IIIB, or IIIC, as this impacts the "N" seventh character.
• Do not use for initial treatment of the fracture or for routine follow-up without evidence of nonunion.
