T68: Hypothermia | ICD-10-CM Code

Clinical notes

Excludes1 (not coded here)

An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).

hypothermia following anesthesia (T88.51)
hypothermia not associated with low environmental temperature (R68.0)
hypothermia of newborn (P80.-)

Excludes2 (not included here)

An Excludes2 note means the excluded condition is not part of this one, but a patient can have both at the same time — in that case both codes may be reported together.

frostbite (T33-T34)

7th character definitions

These definitions specify what each valid 7th-character value means for codes in this category.

[object Object]

7th character note

This category requires a 7th character to indicate additional clinical detail (e.g. encounter type: initial, subsequent, sequela). The code is incomplete without it.

The appropriate 7th character is to be added to code T68

Use additional code

This code represents an underlying condition. When a related manifestation is also present, coding convention calls for an additional code to be listed after this one.

code to identify source of exposure:
Exposure to excessive cold of man-made origin (W93)
Exposure to excessive cold of natural origin (X31)

Documentation support

General coding-documentation guidance — not a substitute for payer-specific requirements or professional coding judgment.

•Confirm the excluded condition(s) listed above are not also present — Excludes1 conditions cannot be coded together with this one.
•If the associated manifestation or related condition noted above is also documented, an additional code should be reported alongside this one.
•This category requires a 7th character. Documentation should clearly indicate the episode of care (initial encounter, subsequent encounter, or sequela).
•As a general rule, code to the highest level of specificity supported by the documentation in the medical record.
