Superficial foreign body, unspecified thigh, sequela

This code indicates a past injury to an unspecified thigh caused by a foreign object lodged superficially under the skin, with persistent symptoms or complications arising from that previous injury. The "sequela" designation signifies that the original acute injury has resolved, but its long-term effects are still being addressed.

Use this code when documenting a patient presenting with ongoing issues, such as chronic pain, scarring, nerve damage, or infection, that are directly attributable to a superficial foreign body injury of the thigh that occurred in the past. This code is appropriate when the foreign body itself may or may not still be present, but the current encounter is for the aftermath of the injury.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the original injury, if known.
• Do not use this code for acute foreign body injuries; instead, use the appropriate S70.35-A code for initial encounters.
• Ensure documentation clearly links the current symptoms or condition to the previous superficial foreign body injury of the thigh.
