Poisoning by other specified agents affecting blood constituents

This code signifies an adverse effect resulting from exposure to a specified substance that primarily impacts the composition or function of the blood. This includes conditions like methemoglobinemia, sulfhemoglobinemia, or other hematologic dyscrasias caused by drug or chemical intoxication. The poisoning directly alters blood components rather than causing systemic organ damage.

Assign this code when documentation clearly states a poisoning event (accidental, intentional, or undetermined) where the primary manifestation is a disruption of blood constituents. Examples include poisoning by aniline dyes, nitrites, or certain medications leading to abnormal hemoglobin states or other blood disorders. Supporting documentation should identify the specific agent and the resulting hematologic abnormality.

• Always code the specific substance responsible for the poisoning using an E-code (E850-E869, E950-E952, E960-E962, E980-E982).
• Distinguish from poisonings affecting other body systems; this code is specific to blood constituent effects.
• Consider an additional code for any associated symptoms or definitive diagnoses if not fully captured by the poisoning code itself.
