17. INJURY AND POISONING (800-999)
Use additional code for retained foreign body, if applicable,(V90.01-V90.9)
Use E code(s) to identify the cause and intent of the injury or poisoning (E800-E999)
Note:
1. The principle of multiple coding of injuries should be followed wherever possible. Combination categories for multiple injuries are provided for use when there is insufficient detail as to the nature of the individual conditions, or for primary tabulation purposes when it is more convenient to record a single code; otherwise, the component injuries should be coded separately.
Where multiple sites of injury are specified in the titles, the word "with" indicates involvement of both sites, and the word "and" indicates involvement of either or both sites. The word "finger" includes thumb.
2. Categories for "late effect" of injuries are to be found at 905-909.
