Superficial foreign body of anus, sequela

This code indicates a superficial foreign object located in the anus, with the encounter being for the management of a sequela (late effect) of that foreign body. This means the initial foreign body has been removed or is no longer present, but the patient is experiencing a residual condition directly resulting from its prior presence.

Use this code when a patient presents with a complication or long-term effect directly attributable to a previously removed or resolved superficial foreign body in the anus. Examples include chronic pain, scarring, or fistula formation that developed after the foreign body was no longer present. Do not use for the initial removal or acute treatment of the foreign body.

• Requires an additional code to specify the nature of the sequela (e.g., chronic pain, scar).
• Confirm the foreign body is no longer present and the current encounter addresses a residual condition.
• Distinguish from acute foreign body encounters, which would use codes from the S30.857A or S30.857D series.
