Other plastic object entering via natural orifice, sequela

This code signifies a long-term or residual effect resulting from a foreign body, specifically a plastic object, that entered the body through a natural opening. The initial acute event has passed, and the patient is now experiencing ongoing issues directly attributable to the past presence of this plastic object.

Use this code when documenting a patient presenting with complications such as strictures, chronic inflammation, scarring, or other persistent sequelae after a plastic foreign body (e.g., a toy part, button, or other plastic item) was previously ingested, inserted, or otherwise entered a natural orifice and has since been removed or passed. This applies when the current encounter addresses these lasting effects, not the initial foreign body event itself.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., K22.2 for esophageal obstruction).
• Ensure documentation clearly links the current condition to a past event involving a plastic foreign body entering a natural orifice.
• The "S" in the 7th character indicates sequela; do not use this for initial encounters or subsequent encounters for active foreign body removal.
