Poisn by mixed bact vaccines w/o a pertuss, slf-hrm, sequela

This code signifies a long-term consequence or complication arising from a deliberate act of self-poisoning with a bacterial vaccine that does not contain a pertussis component. This could include adverse reactions such as chronic pain, organ damage, or persistent neurological issues that developed after the initial acute poisoning event. The "sequela" aspect indicates that the acute phase of the poisoning has passed, and the patient is now experiencing residual effects.

Apply this code when documenting a patient presenting with chronic health problems directly attributable to a past intentional self-harm event involving a non-pertussis bacterial vaccine. This would be used in follow-up encounters for ongoing management of these long-term effects, rather than for the initial acute poisoning. Examples include a patient seeking treatment for persistent autoimmune reactions or chronic neurological deficits years after such an incident.

• Always use this code as a secondary diagnosis, following a code that describes the specific sequela (e.g., chronic kidney disease, neuropathy).
• Ensure documentation clearly links the current condition to the past intentional self-harm by vaccine, and specifies the absence of a pertussis component.
• Verify that the patient's medical record explicitly states the "intentional self-harm" intent of the original poisoning event.
