Displacmnt of int fix of bones of hand and fingers, sequela

This code signifies a long-term complication arising from the displacement of an internal fixation device previously implanted in the bones of the hand or fingers. It indicates that the device, such as a plate, screw, or pin, has shifted from its intended position, leading to ongoing issues. This displacement is not an acute event but rather a residual effect or late complication of the initial fixation.

Use this code when documenting a patient presenting with symptoms or conditions directly attributable to a dislodged or migrated internal fixation device in the hand or fingers, and the displacement occurred in the past. This applies to follow-up encounters where the sequela of the displacement is being managed, even if the original injury or surgery occurred months or years prior.

• Always assign this code as a secondary diagnosis, with the primary diagnosis reflecting the current condition or reason for the encounter (e.g., pain, nonunion, infection).
• Ensure documentation clearly states the displacement is a sequela or late effect rather than an acute event.
• Do not use this code for acute displacement; instead, refer to the appropriate acute displacement codes within the T84.2 category.
