Magnetic metal coin entering via natural orifice, sequela

This code describes the long-term effects or complications arising from a magnetic metal coin having entered the body via a natural opening. It signifies that the initial event of ingestion or insertion has occurred, and the patient is now presenting with sequelae related to that foreign body.

Use this code when documenting a patient presenting with symptoms or conditions that are a direct consequence of a previously ingested or inserted magnetic metal coin. This includes complications such as erosion, perforation, stricture, or other tissue damage identified after the acute event has passed.

• Always use in conjunction with a code describing the specific sequela (e.g., K31.89 for other specified diseases of stomach and duodenum, or K63.8 for other specified diseases of intestine).
• Ensure documentation clearly links the current condition to the prior magnetic metal coin ingestion/insertion.
• Do not use for the initial encounter or acute phase of the foreign body ingestion/insertion.
