Poisn by anticoag antag, vit K and oth coag, slf-hrm, sqla

This code signifies the long-term effects or complications arising from an intentional overdose or self-poisoning with anticoagulant antagonists, vitamin K, or other coagulant medications. These sequelae can include chronic bleeding disorders, organ damage, or other persistent health issues directly attributable to the original poisoning event.

Apply this code when documenting a patient presenting with a current condition that is a direct consequence of a past intentional self-harm poisoning involving anticoagulant antagonists, vitamin K, or other coagulants. This is used for follow-up care or when the sequela is the primary reason for the encounter, long after the acute poisoning has been treated.

• Ensure documentation clearly links the current condition as a residual effect of the past intentional self-harm poisoning.
• Do not use this code for the acute poisoning event itself; use the acute poisoning code with the appropriate seventh character.
• Always sequence this code after the code(s) for the specific sequela being treated.
