Toxic effect of venom of spider, intentional self-harm, subs

This code signifies a patient presenting for follow-up care related to a toxic reaction caused by the venom of a spider other than a black widow or other specified spider. The poisoning was intentionally self-inflicted, indicating a suicide attempt or deliberate self-harm. The patient is no longer in the acute phase of treatment.

Apply this code when documenting subsequent encounters for managing complications, monitoring recovery, or providing ongoing care after an intentional self-poisoning from an unspecified spider's venom. This includes follow-up appointments for wound care, systemic effects, or mental health evaluations after the initial treatment. Do not use for the initial treatment of the acute poisoning.

• Requires an additional code for the specific type of spider if known and not otherwise classified.
• Always sequence this code after any codes for the specific manifestations of the toxic effect.
• Ensure documentation clearly states "intentional self-harm" and "subsequent encounter" to support code assignment.
