About coding aorta thoracic injury
The ICD-10-CM code for aorta thoracic injury is S25.00 (Unspecified injury of thoracic aorta). The official index lists 7 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S25.00.
Within S25.0, choose S25.00 (Unspecified injury of thoracic aorta) only when documentation doesn't support a more specific option: minor laceration of thoracic aorta (S25.01), major laceration of thoracic aorta (S25.02) and other specified injury of thoracic aorta (S25.09).
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.
