Poisn by anticoag antag, vit K and oth coag, asslt, sequela

This code signifies a long-term or residual effect resulting from an intentional act of poisoning with anticoagulant antagonists, vitamin K, or other coagulant agents. These are substances typically used to reverse the effects of anticoagulants or promote clotting. The "sequela" aspect indicates that the acute poisoning event has passed, but the patient is still experiencing lasting health problems directly attributable to that assault.

Use this code when documenting chronic or persistent health issues that are a direct consequence of a past assault involving the administration of anticoagulant antagonists, vitamin K, or other coagulants. This would apply to conditions like ongoing bleeding disorders, organ damage, or neurological deficits that developed after the acute poisoning and are now considered a permanent or long-standing problem.

• Always sequence this sequela code after the code(s) describing the specific residual condition(s) being treated.
• Ensure documentation clearly links the current sequela to a past assault involving the specified substances.
• Do not use this code for the initial acute poisoning event; instead, use the appropriate acute poisoning code with the "A" (initial encounter) or "D" (subsequent encounter) seventh character.
