About T75.3

T75.3 is the ICD-10-CM diagnosis code for motion sickness. 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 (other and unspecified effects of other external causes), T75.3 is specifically for motion sickness. Related codes cover effects of lightning (T75.0), unspecified effects of drowning and nonfatal submersion (T75.1), effects of vibration (T75.2), 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.

Use an additional code for: external cause code to identify vehicle or type of motion (Y92.81-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
