About coding barotrauma
The ICD-10-CM code for barotrauma is T70.29 (Other effects of high altitude). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on T70.29.
Within T70.2, choose T70.29 (Other effects of high altitude) only when documentation doesn't support a more specific option: unspecified effects of high altitude (T70.20).
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.
