Poisoning by purine derivative diuretics

This code signifies an adverse reaction or overdose resulting from a purine derivative diuretic medication. These drugs, such as theophylline, are primarily used for their diuretic and bronchodilator effects, and their toxicity can manifest in various systemic symptoms.

Apply this code when documentation clearly indicates a patient's condition is due to poisoning, overdose, or an adverse effect from a purine derivative diuretic. This includes accidental ingestions, intentional overdoses, or therapeutic misadventures. Supporting documentation should specify the drug class and the resulting clinical presentation.

• Always code the specific manifestation of the poisoning (e.g., convulsions, cardiac arrhythmias) in addition to this code.
• Distinguish between poisoning (adverse effect, overdose) and therapeutic use with adverse effects not classified as poisoning.
• Review medication lists and toxicology screens to confirm the involvement of a purine derivative diuretic.
