Magnetic metal coin entering via natural orifice, subs

This code signifies a follow-up encounter for a patient who previously ingested or otherwise had a magnetic metal coin enter their body via a natural opening (e.g., mouth, nose, ear). The initial event has already been addressed, and this visit pertains to ongoing management, complications, or monitoring related to the foreign body.

Apply this code for subsequent visits where a patient is being monitored for the passage of a magnetic coin, experiencing delayed symptoms, or undergoing follow-up imaging after initial intervention. It is appropriate for encounters addressing complications such as obstruction, perforation, or erosion caused by the magnetic coin.

• Always pair this code with an external cause code (V00-Y99) to describe the circumstances of the event.
• Ensure the "D" seventh character is used for subsequent encounters, indicating ongoing care after the initial treatment.
• Do not use this code for the initial encounter; a code with an "A" seventh character would be appropriate for the initial presentation.
