Toxic effect of chewing tobacco, assault, sequela

This code describes the long-term or residual effects resulting from an intentional poisoning by chewing tobacco, where the intent was to harm another person. These sequelae can manifest in various organ systems, such as chronic gastrointestinal issues, oral cancers, or cardiovascular complications, that persist after the acute toxic event has resolved.

Use this code when documenting a patient presenting with a current health condition that is a direct consequence of a past assault involving chewing tobacco. This applies to situations where the acute toxic event is no longer active, but its lasting impact on the patient's health is being treated or evaluated.

• Always ensure documentation clearly links the current condition to the past chewing tobacco assault.
• Requires an additional code for the specific sequela (e.g., C06.9 for malignant neoplasm of mouth, unspecified).
• The "S" seventh character indicates sequela, meaning it's used for complications or conditions that arise as a direct result of an injury or illness.
