Assault by letter bomb, sequela

This code signifies the long-term or residual effects resulting from an injury sustained due to an assault involving a letter bomb. It is used to document conditions that manifest after the initial acute phase of the injury has passed, such as chronic pain, scarring, or psychological trauma.

Apply this code when a patient presents with a current condition that is a direct consequence of a past assault by a letter bomb. This includes follow-up visits for ongoing treatment of permanent disabilities, disfigurement, or mental health disorders directly attributable to the original incident.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., T90.5XXS for sequela of head injury).
• Ensure documentation clearly links the current condition to the past assault by letter bomb.
• Do not use for acute injuries; refer to the appropriate acute injury codes for the initial encounter.
