Toxic effect of venom of gila monster, undetermined, subs

This code signifies a toxic reaction to gila monster venom where the intent (accidental, intentional self-harm, assault) is not documented or cannot be determined. The "subsequent encounter" indicates that the patient is receiving follow-up care for the initial toxic effect, such as monitoring for lingering symptoms or managing complications.

Apply this code when a patient presents for ongoing treatment or evaluation of symptoms stemming from a gila monster bite, and the medical record does not specify whether the exposure was accidental, intentional, or due to an assault. This is appropriate for follow-up visits after the acute phase of treatment.

• Requires an additional code for the specific symptoms or manifestations of the toxic effect.
• Only use for subsequent encounters; an initial encounter would use the 'A' seventh character.
• Ensure documentation clearly supports the "undetermined" intent and the follow-up nature of the visit.
