Disp fx of anterior wall of left acetabulum, sequela

This code signifies a past fracture of the front portion of the left hip socket that was out of alignment, and the patient is now experiencing residual effects or complications from that old injury. These sequelae could include ongoing pain, limited range of motion, post-traumatic arthritis, or other long-term issues directly attributable to the healed or healing displaced anterior acetabular fracture.

Apply this code when documenting a patient presenting with chronic problems directly stemming from a previously sustained and treated displaced fracture of the anterior wall of the left acetabulum. This is appropriate for follow-up encounters where the primary reason for the visit is to address the long-term consequences of the old injury, not the acute fracture itself.

• Always use this code as a secondary diagnosis, following a code describing the specific sequela (e.g., M16.4 for post-traumatic arthritis of the hip).
• Ensure documentation clearly links the current condition to the old displaced anterior acetabular fracture.
• Do not use this code for the initial treatment of the acute fracture or for routine follow-up without documented sequelae.
