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.
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.

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.

Type 2 Excludes
- hypothermia and other effects of reduced temperature (T68, T69.-)
- T33 Superficial frostbite
- T34 Frostbite with tissue necrosis
- A disorder characterized by an abnormally low body temperature. Treatment is required when the body temperature is 35c (95f) or below.
- Abnormal low body temperature
- Abnormally low body temperature.
- Abnormally low body temperature. Treatment is required when the body temperature is 35c (95f) or below. Symptoms include decreased mental function, lethargy, and disorientation.
- Body temperature below normal range
- Cold weather can affect your body in different ways. You can get frostbite, which is frozen body tissue. Your body can also lose heat faster than you can produce it. The result is hypothermia, or abnormally low body temperature. It can make you sleepy, confused and clumsy. Because it happens gradually and affects your thinking, you may not realize you need help. That makes it especially dangerous. A body temperature below 95![degree sign]! f is a medical emergency and can lead to death if not treated promptly. Anyone who spends much time outdoors in cold weather can get hypothermia. You can also get it from being cold and wet, or under cold water for too long. Babies and old people are especially at risk. Babies can get it from sleeping in a cold room. Centers for Disease Control and Prevention.
- Lower than normal body temperature, especially in warm-blooded animals.
