Poisoning by vitamins, accidental (unintentional), sequela

This code signifies a long-term health condition or complication that arose from an accidental overdose or toxic exposure to vitamins. It indicates that the acute phase of the poisoning has passed, but residual effects persist, impacting the patient's current health status.

Apply this code when documenting a patient presenting with chronic symptoms or lasting damage directly attributable to a past, unintentional vitamin poisoning. Examples include persistent organ damage (e.g., liver damage from hypervitaminosis A), neurological deficits, or metabolic disturbances that are a direct consequence of the prior toxic event.

• Always sequence this code after the code(s) identifying the specific sequela (e.g., K71.1 for toxic liver disease).
• Ensure documentation clearly links the current condition to a past accidental vitamin poisoning.
• Do not use for acute vitamin poisoning; this code is exclusively for sequelae.
