2017/18 ICD-10-CM Diagnosis Code T68

Hypothermia

Applicable To
  • Accidental hypothermia
  • Hypothermia NOS

Use Additional Help
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

    • Exposure to weather conditions
    Type 1 Excludes

Type 1 Excludes
Type 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as T68. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • hypothermia following anesthesia (

    • hypothermia NOS (accidental) (T68)
    • hypothermia due to anesthesia (T88.51)
    • hypothermia due to low environmental temperature (T68)
    • newborn hypothermia (P80.-)

  • hypothermia of newborn (

    )
Type 2 Excludes
Type 2 Excludes Help
A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (T68) and the excluded code together.
  • frostbite (T33-T34

    • hypothermia and other effects of reduced temperature (T68, T69.-)

    • T34 Frostbite with tissue necrosis
