T75.23Vertigo from infrasound

T75.23 is the ICD-10-CM diagnosis code for vertigo from infrasound. 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 T75.2 (effects of vibration), T75.23 is specifically for vertigo from infrasound. Related codes cover unspecified effects of vibration (T75.20), Pneumatic hammer syndrome (T75.21), traumatic vasospastic syndrome (T75.22) and other effects of vibration (T75.29).

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 T75.23 together with the conditions in its Excludes1 note: vertigo NOS (R42).

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