Poisn by histamine H2-receptor blockers, assault, sequela

This code indicates a long-term health problem or complication resulting from an intentional overdose or poisoning by histamine H2-receptor blockers, such as cimetidine or ranitidine, where the poisoning was inflicted by another person. The patient is experiencing persistent effects directly attributable to this past assault.

Use this code when documenting a patient presenting with a chronic condition or lasting injury that is a direct consequence of a previous poisoning by an H2-receptor blocker, and the poisoning was determined to be an assault. This code is appropriate for follow-up encounters where the sequelae are being managed, even if the acute poisoning event occurred in the distant past.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past H2-receptor blocker poisoning and specifies the assault intent.
• Do not use for acute poisoning events; this code is exclusively for the long-term effects.
