Toxic effect of chewing tobacco, undetermined, init encntr

This code signifies a patient presenting with adverse health effects resulting from exposure to chewing tobacco, where it is unclear whether the exposure was accidental or intentional. The "initial encounter" designation indicates that this is the first time the patient is receiving active treatment for this specific toxic effect.

Apply this code when a patient experiences symptoms such as nausea, vomiting, dizziness, or other systemic reactions directly attributable to chewing tobacco, and the circumstances surrounding the exposure (e.g., accidental ingestion by a child, intentional use with an unexpected reaction) are not yet determined. This is appropriate for the initial evaluation and management of the acute toxic event.

• Always assign an additional code for the specific manifestation(s) of the toxic effect (e.g., R11.2 for nausea and vomiting).
• Do not use this code if the intent (accidental vs. intentional self-harm) is clearly documented; instead, use the appropriate T65.211- or T65.212- series code.
• The "A" seventh character is only for the initial encounter; subsequent encounters for the same condition will require a "D" or "S" seventh character.
