Poisoning by thrombolytic drug, undetermined, sequela

This code signifies a long-term health problem or complication arising from an indeterminate poisoning by a thrombolytic medication. The original poisoning event's intent (accidental, intentional self-harm, assault) could not be determined at the time of the initial event. The patient is now presenting for care related to a residual effect of that past poisoning.

Apply this code when a patient is being treated for a chronic condition, permanent injury, or lasting sequela directly attributable to a previous thrombolytic drug poisoning where the intent of the poisoning was unknown. Examples include persistent organ damage, neurological deficits, or other long-term complications following such an event. This code is not for the initial acute poisoning.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past thrombolytic poisoning with undetermined intent.
• Do not use for acute poisoning events; those require codes from the initial encounter (A, D, or S) categories.
