Disp fx of anterior wall of right acetabulum, sequela

This diagnosis describes a past injury involving a break in the front part of the right hip socket that was out of alignment. The "sequela" indicates that this code is used for complications or conditions arising directly from the initial fracture, even after the acute phase of healing has passed. These long-term effects could include chronic pain, nonunion, malunion, or post-traumatic arthritis.

This code is appropriate for documenting ongoing issues or late effects directly attributable to a previously displaced fracture of the anterior wall of the right acetabulum. It should be used when the patient is presenting for treatment of these residual problems, not for the initial acute injury. Examples include follow-up visits for chronic pain management, evaluation of limited range of motion, or surgical intervention for complications like avascular necrosis stemming from the original fracture.

• Always assign an additional code(s) to specify the nature of the sequela (e.g., M16.4 for unilateral post-traumatic osteoarthritis, right hip).
• Ensure documentation clearly links the current condition to the previous displaced anterior acetabular fracture.
• Do not use this code for the initial treatment of the acute fracture; use the appropriate acute fracture code for that encounter.
