About coding lightning
The ICD-10-CM code for lightning is T75.00 (Unspecified effects of lightning). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on T75.00.
Within T75.0, choose T75.00 (Unspecified effects of lightning) only when documentation doesn't support a more specific option: shock due to being struck by lightning (T75.01) and other effects of lightning (T75.09).
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.
