Displ subtrochnt fx l femr, 7thM

This code describes a situation where the upper part of the left thigh bone, specifically below the lesser trochanter, has broken and the bone fragments are no longer aligned. This particular fracture was initially an open fracture (meaning the skin was broken), classified as Type I or II, and has now failed to heal properly, resulting in a nonunion. The patient is presenting for follow-up care or treatment related to this ongoing healing complication.

Use this code for a patient who has previously undergone treatment for an open subtrochanteric fracture of the left femur, and during a subsequent visit, the physician documents that the fracture has not healed and is considered a nonunion. This applies when the initial open fracture was classified as Type I or II. This code is appropriate for encounters involving ongoing management, surgical intervention for nonunion, or evaluation of the nonunion.

• Ensure documentation clearly specifies "nonunion" and that the initial fracture was an "open fracture type I or II."
• Verify the laterality (left femur) and the specific anatomical site (subtrochanteric).
• This "M" encounter code indicates subsequent care for the nonunion, not the initial treatment of the acute fracture.
