Exposure to other animate mechanical forces (W64)
The ICD-10 code W64 and its related subcategories identify and classify injuries caused by exposure to other animate mechanical forces, primarily animal-related injuries such as bites, stings, scratches, and crushes. These codes are used specifically to document encounters involving wounds or trauma inflicted by animals and other living creatures.
W64.XXXA indicates the initial encounter for such injuries, covering a broad range of cases including animal bites to fingers, feet, face, and limbs, and stings by various sea and land creatures like jellyfish or stingrays. The detailed synonyms like "open wound due to animal bite" or "fish sting" support precise coding, helping coders relate common injury descriptions to this specific code group. Subsequent encounters and sequelae after the initial treatment are coded with W64.XXXD and W64.XXXS, respectively, enabling ongoing monitoring or complications following the injury. This classification facilitates accurate reporting and treatment documentation for injuries resulting from animate mechanical forces, distinguishing them from other external causes.

Instructional Notations
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- exposure to nonvenomous animal NOS
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- contact with venomous animal T63
7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
- The appropriate 7th character is to be added to code W64
