About coding Trichophytobezoar
The ICD-10-CM code for Trichophytobezoar is T18.9 (Foreign body of alimentary tract, part unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on T18.9.
Within T18, choose T18.9 (of alimentary tract, part unspecified) only when documentation doesn't support a more specific option: in mouth (T18.0), in esophagus (T18.1), in stomach (T18.2), in small intestine (T18.3), in colon (T18.4), in anus and rectum (T18.5) and in other parts of alimentary tract (T18.8).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
