Poisoning by mercurial diuretics

This code signifies an adverse health effect resulting from the ingestion, absorption, or exposure to mercurial diuretics. It represents a toxic reaction to medications containing mercury, historically used for their diuretic properties, leading to various systemic symptoms.

Apply this code when documentation clearly indicates a patient's illness or injury is directly attributable to poisoning by a mercurial diuretic. This typically involves cases of overdose, accidental ingestion, or adverse drug reactions where toxicity is the primary concern.

• Always sequence this code as a primary diagnosis when it is the reason for the encounter.
• Look for specific mention of "mercurial diuretic" in the medical record; do not assume based on general diuretic poisoning.
• Consider additional codes for specific manifestations of the poisoning (e.g., renal failure, neurological symptoms).
