Bitten by squirrel, initial encounter

This code signifies an injury resulting from a squirrel bite. It specifically indicates the initial presentation for medical attention related to this incident, implying the first time the patient is seen for evaluation and treatment of the bite wound.

Apply this code when a patient presents to a healthcare facility with a documented squirrel bite. This includes emergency department visits, urgent care consultations, or initial primary care appointments for wound assessment, cleaning, and potential prophylactic treatment.

• Always assign an external cause code (W53.21XA) in conjunction with a code for the specific bite wound (e.g., S61.01XA for open wound of finger).
• Ensure the encounter is truly the "initial encounter" for this specific injury. Subsequent care would use a different seventh character.
• Verify documentation clearly states the animal involved was a squirrel to differentiate from other rodent bites.
