Open bite of unspecified hand, initial encounter

This code signifies an open wound on an unspecified hand caused by a bite, where the skin and underlying tissues have been penetrated. This type of injury carries a risk of infection due to the nature of the bite.

Apply this code for the initial treatment of a patient presenting with an open bite wound to either the left or right hand, when the specific hand is not documented. This includes animal bites, human bites, or other bite-related injuries that break the skin.

• Ensure the documentation clearly states an "open bite" and specifies the hand as "unspecified" or lacks laterality.
• This code is for the initial encounter only; subsequent care will require a different seventh character.
• Always code the external cause of the injury (e.g., W53.01XA for bite by dog) in addition to this diagnosis.
