Superficial foreign body of scalp, sequela

This code describes a superficial foreign object embedded in the scalp, where the current encounter is for a sequela or late effect of the initial injury. This indicates that the initial foreign body removal or treatment has already occurred, and the patient is now presenting with a complication or residual condition directly attributable to that past event.

Use this code when a patient presents with a long-term complication, such as scarring, chronic pain, infection, or nerve damage, directly resulting from a previously treated superficial foreign body in the scalp. Documentation should clearly link the current condition to the prior foreign body injury and specify that the current encounter addresses a sequela.

• Always use a seventh character "S" for sequela when the current encounter is for a complication or late effect of the initial injury.
• Code the specific sequela (e.g., scar, chronic pain) first, followed by this code to indicate the cause.
• Ensure documentation explicitly states the foreign body was superficial and located on the scalp, and that the current presentation is a sequela.
