Contact with crocodile or alligator (W58)
The ICD-10 code W58 series is used to classify injuries and accidents involving contact with crocodiles or alligators. These codes precisely identify the nature of the encounter, such as being bitten, struck, or crushed by these reptiles.
The codes under W58 cover various scenarios, including initial, subsequent, and sequela (long-term) encounters with crocodiles or alligators. For example, W58.01XA denotes an initial encounter with a bite from an alligator, also known as a "Bite of alligator" or "Bite of reptile." Similarly, W58.11XA refers to an initial bite by a crocodile, helping coders assign the correct code for medical records related to reptile-related injuries. Other codes in this section specify injuries like being struck or crushed by these animals. This classification plays an essential role in capturing the precise cause of injury related to crocodile or alligator contact for clinical documentation and reporting purposes.

Instructional Notations
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 each code from category W58
