Bezoar entering via natural orifice, initial encounter

This code signifies the presence of a bezoar, a mass of undigested material, that has entered or is actively passing through a natural body opening. This typically involves the bezoar moving through the gastrointestinal tract, potentially causing obstruction or other complications.

Apply this code when documentation clearly indicates a bezoar is in the process of entering or exiting a natural orifice, such as the mouth, anus, or urethra. This is appropriate for initial presentations where the bezoar's passage is the primary concern or focus of treatment.

• Ensure the documentation specifies "initial encounter" for this specific bezoar event.
• Do not use for bezoars that are merely present within an organ without active passage through an orifice.
• Code any associated complications, such as obstruction or perforation, in addition to this code.
