Poisoning by electrolytic, caloric, and water-balance agents

This code signifies an adverse reaction or overdose due to substances that regulate electrolytes, calories, or water balance within the body. This includes poisoning from agents like antacids, laxatives, diuretics, or substances that alter fluid and electrolyte levels. The poisoning can result from accidental ingestion, therapeutic misadventure, or intentional self-harm.

Use this code when documentation clearly indicates a poisoning event caused by medications or substances primarily affecting electrolyte, caloric, or water homeostasis. This applies to acute toxic effects, not long-term complications or chronic conditions. Supporting documentation should specify the substance ingested and the resulting adverse effects.

• Always sequence this code first if it is the primary reason for the encounter, followed by codes for specific manifestations of the poisoning.
• Distinguish between poisoning (adverse effect due to incorrect use or overdose) and adverse effect (correct use of medication).
• Ensure the documentation specifies the substance involved to confirm it falls under "electrolytic, caloric, and water-balance agents."
