Toxic effect of venom of N & S American snake, acc, subs

This code signifies a toxic reaction resulting from an accidental bite by a North or South American snake species, excluding rattlesnakes, coral snakes, and other specified venomous snakes. The "subsequent encounter" indicates that the patient is receiving follow-up care for the initial injury, such as wound management, monitoring for delayed effects, or rehabilitation.

Apply this code when a patient presents for ongoing treatment of an accidental envenomation from a non-specified North or South American snake. This includes scenarios like follow-up appointments for wound care after initial antivenom administration, management of lingering symptoms, or physical therapy for affected limbs.

• Ensure documentation clearly specifies the encounter as "subsequent" for ongoing care related to the initial bite.
• Verify the snake species is identified as a North or South American type, but not one with a more specific ICD-10-CM code.
• Always sequence this code after the primary diagnosis for the specific toxic effect or injury if applicable.
