Non-magnetic metal bead entering via natural orifice, init

This code signifies the accidental entry of a non-magnetic metal bead into a patient's body via a natural opening, such as the nose, ear, mouth, or rectum. This foreign body is typically small and smooth, distinguishing it from other types of ingested or inserted objects.

Apply this code when documenting the initial presentation and treatment for a patient who has, for example, inhaled a small metal bead, inserted one into an ear canal, or ingested one that has not yet passed. This code is appropriate for the first encounter related to this specific foreign body event.

• Ensure the foreign body is explicitly documented as a "non-magnetic metal bead" and entered through a "natural orifice."
• Confirm this is the initial encounter for the foreign body; subsequent encounters would use a different seventh character.
• Always code with an external cause code (V00-Y99) to describe the circumstances of the event.
