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.
LATE EFFECTS OF INJURIES, POISONINGS, TOXIC EFFECTS, AND OTHER EXTERNAL CAUSES (905-909)
Note:
These categories are to be used to indicate conditions classifiable to 800-999 as the cause of late effects, which are themselves classified elsewhere. The "late effects" include those specified as such, or as sequelae, which may occur at any time after the acute injury.
905: Late effects of musculoskeletal and connective tissue injuries
906: Late effects of injuries to skin and subcutaneous tissues
907: Late effects of injuries to the nervous system
908: Late effects of other and unspecified injuries
909: Late effects of other and unspecified external causes
