Poisoning by anticoagulants, intentional self-harm, sequela

This code signifies a long-term consequence or residual effect resulting from a deliberate overdose of anticoagulant medication. It indicates that the patient intentionally self-poisoned with blood thinners, and they are now experiencing a chronic or late-developing complication directly attributable to that event. This is not for the acute poisoning itself, but for its lasting impact.

Apply this code when documenting a patient presenting with a sequela (e.g., chronic bleeding disorder, organ damage, or other persistent health issues) that is directly linked to a past intentional self-harm event involving anticoagulants. This code is appropriate for follow-up encounters addressing these chronic complications, long after the initial acute poisoning has been treated.

• 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 intentional anticoagulant overdose.
• Do not use for acute poisoning or adverse effects of properly administered anticoagulants.
