Poisoning by vitamins, undetermined, sequela

This code signifies a long-term or residual effect resulting from a past poisoning by vitamins, where the intent of the poisoning (e.g., accidental, intentional self-harm) could not be determined. It indicates that the patient is currently experiencing a health problem directly attributable to a previous, unclarified vitamin overdose.

Apply this code when a patient presents with a chronic condition or persistent symptom that is documented as a consequence of a prior vitamin poisoning event, and the medical record does not specify whether the poisoning was accidental, intentional, or assault. This is appropriate for follow-up encounters addressing these lasting effects.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past vitamin poisoning and states the undetermined intent.
• Avoid using this code for acute poisoning events; it is strictly for residual effects.
