Nondisp articular fracture of head of unsp femur, sequela

This code describes a healed or chronic injury involving a fracture of the femoral head that did not shift out of its normal anatomical position. The fracture affects the joint surface of the femur, and the "sequela" designation indicates that this code is used for complications or conditions arising directly from the initial injury, after the acute phase of healing has passed.

Use this code when documenting long-term effects, complications, or follow-up care related to a previously sustained, nondisplaced articular fracture of the femoral head. This is appropriate for patients presenting with ongoing pain, stiffness, or other issues directly attributable to the old fracture, such as post-traumatic arthritis or avascular necrosis. It should be applied when the initial fracture has healed, but its residual effects are still being managed.

• Always assign a seventh character "S" for sequela when the patient is being treated for a complication or late effect of the original fracture.
• Do not use this code for the initial or subsequent encounter for the acute fracture; those require different seventh characters.
• Consider additional codes for specific complications (e.g., M16.x for post-traumatic osteoarthritis of the hip) if documented.
