Toxic effect of unsp spider venom, assault, subs encntr

This code signifies a harmful reaction to venom from an unidentified spider, occurring as a result of an intentional act of violence. The "subsequent encounter" indicates that the patient is receiving follow-up care for the initial injury, such as wound management, monitoring for systemic effects, or ongoing treatment.

Apply this code when documenting an outpatient visit or inpatient stay for a patient who is being treated for complications or ongoing effects of a spider bite sustained during an assault. This includes situations where the specific type of spider is unknown, and the patient is no longer in the acute phase of treatment.

• Ensure documentation clearly states the bite was due to an assault and that it's a follow-up visit.
• Do not use for initial encounters; a different seventh character would be appropriate for the initial treatment.
• If the specific spider is identified, a more precise code from the T63.3 category should be used.
