External constriction of flank, sequela

This code describes the long-term effects or complications resulting from an external force or object constricting the flank area. This could include chronic pain, nerve damage, scarring, or impaired function that persists after the initial injury has healed. It indicates that the constriction is no longer present, but its lasting consequences are being addressed.

Use this code when documenting a patient presenting with a sequela (late effect) directly attributable to a past external constriction of the flank. Examples include chronic pain from a previous tight belt injury, nerve damage from prolonged pressure, or scar tissue formation impacting mobility. The initial acute injury must have resolved, and the current encounter addresses the residual condition.

• Always sequence this code after the code for the specific sequela (e.g., chronic pain, scar, nerve damage).
• Ensure documentation clearly links the current condition to a past external constriction of the flank.
• Do not use for acute or current external constriction; this code is specifically for sequelae.
