Nondisplaced transverse fracture of unsp acetabulum, sequela

This code describes a past injury involving a fracture of the acetabulum, specifically a transverse fracture that did not shift from its original position. The exact location within the acetabulum is not specified. The "sequela" designation indicates that this code is used to report a condition or complication arising directly from the original fracture, even after the acute phase of the injury has passed.

This code is appropriate when a patient presents with a long-term problem or residual effect directly attributable to a previously sustained, nondisplaced transverse acetabular fracture of an unspecified site. Examples include chronic pain, stiffness, or degenerative changes in the hip joint that are documented as a consequence of the old fracture. It should be used when the patient is no longer in the active treatment phase for the initial fracture.

• Always assign an additional code to describe the specific sequela (e.g., M16.11 for unilateral primary osteoarthritis, right hip).
• Ensure documentation clearly links the current condition to the old acetabular fracture.
• Verify that the fracture was indeed nondisplaced and transverse, and that the encounter is for a sequela, not the initial treatment or routine follow-up during the healing phase.
