ICD-10 code for effects of exposure

The ICD-10-CM code for effects of exposure is T73.9 (Effect of deprivation, unspecified).

Within T73, choose T73.9 (Effect of deprivation, unspecified) only when documentation doesn't support a more specific option: Starvation (T73.0), deprivation of water (T73.1), exhaustion due to exposure (T73.2), exhaustion due to excessive exertion (T73.3) and other effects of deprivation (T73.8).

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.

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