Bitten by nonvenomous snake, initial encounter

This code signifies an injury resulting from a bite by a nonvenomous snake. Such bites typically cause localized trauma, including puncture wounds, lacerations, bruising, and potential secondary infection, but do not involve systemic envenomation.

Apply this code for the initial presentation and treatment of a patient who has sustained a bite from a snake confirmed or presumed to be nonvenomous. This includes emergency department visits, urgent care encounters, or initial physician office visits for wound assessment and management.

• Always assign an external cause code (e.g., Y92.830 for wilderness area) in conjunction with this code to fully describe the circumstances of the injury.
• Do not use this code for bites from venomous snakes; refer to the T63.0- series for those cases.
• Ensure the "A" for initial encounter is appropriate; subsequent encounters for follow-up care or complications will require different seventh characters.
