Superficial foreign body, left knee, sequela

This code describes the long-term effects or complications arising from a superficial foreign body embedded in the left knee. It indicates that the initial injury has resolved, but residual issues related to the foreign object are still present. These sequelae could include chronic pain, scarring, or restricted movement.

Use this code when documenting a patient presenting with ongoing symptoms or conditions directly attributable to a previously removed or retained superficial foreign body in the left knee. This applies to follow-up encounters where the primary injury has healed, but its lasting impact is being addressed.

• Always ensure documentation clearly links the current symptoms to the past superficial foreign body in the left knee.
• This code requires a seventh character "S" for sequela, indicating a late effect.
• Do not use this code for acute foreign body encounters; those require an initial encounter or subsequent encounter seventh character.
