Poisoning by oth vaccines and biolg substnc, self-harm, init

This code signifies a deliberate act of self-poisoning using a vaccine or other biological substance, such as antitoxins, immune globulins, or blood products. The patient intentionally administered or ingested the substance with the intent to cause harm to themselves.

Apply this code when documentation clearly indicates a suicide attempt or intentional self-inflicted injury involving a biological substance. This is for the initial encounter where the patient is first seen for this poisoning event.

• Always assign an additional code for the specific vaccine or biological substance if known and documented.
• Ensure the documentation explicitly states "intentional self-harm" or "suicide attempt" to support this code.
• This "initial encounter" code is used as long as the patient is receiving active treatment for the poisoning.
