About T75.1
T75.1 is the ICD-10-CM diagnosis code for unspecified effects of drowning and nonfatal submersion. It belongs to category T75 (other and unspecified effects of other external causes), block T66-T78 (other and unspecified effects of external causes) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
Within T75, choose T75.1 (Unspecified effects of drowning and nonfatal submersion) only when documentation doesn't support a more specific option: effects of lightning (T75.0), effects of vibration (T75.2), motion sickness (T75.3), electrocution (T75.4) and other specified effects of external causes (T75.8).
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.
Don't report T75.1 together with the conditions in its Excludes1 note: specified effects of drowning- code to effects.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
