Toxic effect of chewing tobacco, undetermined, subs encntr

This code describes the toxic effects resulting from exposure to chewing tobacco where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. The "D" seventh character indicates this is for a subsequent encounter, meaning the patient is receiving follow-up care for the initial toxic effect.

This code is appropriate for follow-up visits when a patient is being treated for symptoms or complications directly attributable to chewing tobacco exposure, and the circumstances surrounding the exposure remain unclear. Examples include ongoing management of oral lesions, cardiovascular issues, or other systemic effects linked to chewing tobacco toxicity, where the initial encounter for the poisoning has already been coded.

• Ensure the documentation clearly states "undetermined" intent for the chewing tobacco exposure.
• Only use the "D" seventh character for follow-up care after the acute phase of treatment.
• Code any specific symptoms or manifestations of the toxic effect in addition to this code.
