Poisn by electrolytic/caloric/wtr-bal agnt, acc, sequela

This code signifies a long-term or residual effect stemming from an accidental poisoning by substances that disrupt the body's electrolyte, caloric, or water balance. These agents can include things like excessive intake of certain minerals, diuretics, or substances causing severe dehydration or overhydration. The sequela represents the lasting health problems that persist after the acute poisoning event has resolved.

Apply this code when documenting chronic kidney disease, persistent neurological deficits, or ongoing cardiac arrhythmias that are directly attributed to a past accidental poisoning by electrolytic, caloric, or water-balance agents. This code is appropriate for follow-up encounters where the primary focus is managing these enduring complications.

• Always code the specific sequela first, followed by this code to indicate the external cause.
• Ensure documentation clearly links the current condition to the past accidental poisoning.
• Do not use this code for the initial acute poisoning event; use the acute poisoning code with the appropriate seventh character for initial encounter.
