Displaced fracture of lunate, unspecified wrist, sequela

This code indicates a past injury involving a displaced fracture of the lunate bone in the wrist, where the specific wrist (left or right) was not documented at the time of the initial injury. The "sequela" designation means this code is used for conditions or complications arising as a direct result of that previous fracture, even after the acute phase of healing has passed.

Use this code when a patient presents with a long-term complication or residual effect from a previously sustained, displaced lunate fracture where the laterality was unspecified. This could include chronic pain, stiffness, nonunion, malunion, or post-traumatic arthritis directly attributable to the old injury. It is appropriate for follow-up encounters addressing these persistent issues.

• Always ensure documentation clearly links the current condition to the previous lunate fracture.
• Do not use this code for the initial treatment of an acute fracture; it is strictly for sequelae.
• If laterality is now known or documented, use a more specific sequela code (e.g., S62.121S for right, S62.122S for left).
