974.4
ICD-9-CMThis code represents an adverse health event resulting from the toxic effects of diuretics other than those specifically classified elsewhere. It indicates a patient has experienced poisoning due to an overdose, accidental ingestion, or adverse reaction to a diuretic medication not falling into categories like mercurial, loop, or thiazide diuretics. The poisoning can manifest with various symptoms depending on the specific diuretic and dose.
Use this code when documentation clearly states poisoning by a diuretic that is not a mercurial, loop, or thiazide type. This includes scenarios such as an accidental overdose of a potassium-sparing diuretic or an intentional self-harm attempt involving a miscellaneous diuretic. Supporting documentation should specify the diuretic involved and the toxic effects observed.
