Introduction to the Occupational Injury and Illness Classification Manual Occupational Injury and Illness Classification Manual 12/92 1-2 1.0 Introduction to the Occupational Injury and Illness Classification Manual The Occupational Injury and Illness Classification Manual (OI&ICM) provides a classification system for use in coding the case characteristics of injuries and illnesses in the Occupational Safety and Health (OSH) program and the Census of Fatal Occupational Injuries (CFOI) program. This manual contains the rules of selection, code descriptions, code titles, and indices, for the following code structures: Nature of Injury or Illness, Part of Body Affected, Source of Injury or Illness, Event or Exposure, and Secondary Source of Injury or Illness. The Occupational Injury and Illness Classification Manual was developed by the Bureau of Labor Statistics' Classification Structure Team with input from data users and States participating in the BLS Occupational Safety and Health (OSH) Federal/State cooperative programs. The Occupational Injury and Illness Classification System contains the following code structures to be used in coding the case characteristics of occupational injuries and illnesses in the OSH and CFOI statistical programs: · Nature of Injury or Illness · Part of Body Affected · Source of Injury or Illness/Secondary Source of Injury or Illness · Event or Exposure The OI&ICM is arranged in a structured format so that any section of the manual may be removed for use independently as required by the user. This also allows future updates to be made without having to replace the whole manual. This manual is designed to accommodate the coder of injury, illness, and fatality data provided by the OSH and CFOI programs. Therefore, this manual is a reference tool that enables the coder to determine the proper Nature, Part of Body Affected, Source, Event, and Secondary Source code for any given injury or illness case in an accurate and timely manner. Each code structure in this manual is presented with and without the code descriptions. The code descriptions provide more detail about the codes themselves. The descriptions are extremely useful in determining the make-up of the code categories--the kind of information that each code is trying to capture. The description often gives examples of the codes that would be selected for rare and unusual injury and illness cases. After becoming familiar with the code descriptions, the coder will find the code titles and the alpha indices at the end of the manual to be helpful in expediting the coding process. Exhibit 1.0 gives an overview of the Occupational Injury and Illness Classification Manual.

RULES OF SELECTION: 1.1 Name the injury or illness indicated on the source document. Example: For strained back, choose Sprains, strains, tears. 1.2 When two or more injuries or illnesses are indicated, and one is a sequela, aftereffect, or complication due to medical treatment, choose the initial injury or illness. Example: If a laceration became infected developing into septicemia, choose Cuts, lacerations. 1.3 When two or more injuries or illnesses are indicated and one is more severe than the other(s), select the more severe injury or illness. Example: If sprained finger and fractured wrist, choose Fractures. 1.3.1 When a single event or exposure produces an injury and transmits a disease simultaneously, and one is more severe than the other(s), select the more severe injury or disease. Example: If a needle stick produces a puncture wound and transmits an infectious disease, serum hepatitis, choose serum hepatitis. 1.4 When two or more injuries or illnesses are indicated but no one can be determined as being more severe than the others, select the appropriate multiple injuries or illnesses classification code. Example: For fractured and burned left leg, choose Fractures and burns. Occupational Injury and Illness Classification Manual 12/92 2.1-3 2.1.2 Nature of Injury or Illness--Titles and Descriptions The Nature of Injury or Illness code structure is arranged so that traumatic injuries and disorders are listed first (in Division 0) while diseases are listed in Divisions 1 through 8. Division 8 classifies multiple physical characteristerics whose individual codes are found in Divisions 1 through 5. Nature of Injury or Illness code description pages are numbered from DN-1 through DN-40 (the "D" meaning "description, the "N" meaning "nature"). The divisions are identified by title at the top right corner of each page. The Nature of Injury or Illness divisions are arranged as follows: DIVISION TITLE 0 Traumatic Injuries and Disorders 1 Systemic Diseases or Disorders 2 Infectious and Parasitic Diseases 3 Neoplasms, Tumors, and Cancer 4 Symptoms, Signs, and Ill-defined Conditions 5 Other Conditions or Disorders 8 Multiple Diseases, Conditions, or Disorders 9999 Nonclassifiable Occupational Injury and Illness Classification Manual 12/92 THIS PAGE INTENTIONALLY LEFT BLANK NATURE TRAUMATIC INJURIES AND DISORDERS 0* TRAUMATIC INJURIES AND DISORDERS This division classifies traumatic injuries and disorders, effects of external agents, and poisoning. Generally, a traumatic injury or disorder is the result of a single incident, event, or exposure. 00 Traumatic injuries and disorders, unspecified This major group classifies traumatic injuries and disorders when the only information available describes the incident as traumatic. For example, employee was hurt in car accident. 01* Traumatic injuries to bones, nerves, spinal cord This major group classifies traumatic injuries to the bones, nerves, or spinal cord which include breaking and dislocating bones and cartilage and traumatic injury to the brain, spinal cord, and nerves. 010 Traumatic injuries to bones, nerves, spinal cord, unspecified 011 Dislocations This nature group classifies displacement or dislocation of bone or cartilage. Includes: subluxations; slipped, ruptured, or herniated disc; partial displacement; and fractured or broken cartilage 012 Fractures This nature group classifies traumatic injuries that result in fractures of bones or teeth. Includes: closed fractures for which no open wound exists; open fractures for which there is an accompanying open wound; comminuted, compound, depressed, elevated, fissured, greenstick, impacted, linear, march, simple, and spiral fracture; and slipped epiphysis. Excludes: fatal fracture of the back (018), neck (018), rib (094), or skull (068); fracture of cartilage (011); malunion (17); nonunion (17); pathological or spontaneous fracture (17) 013 Traumatic injuries to spinal cord This nature group classifies traumatic injuries to the spinal cord. Includes: severed spinal cord, nonfatal severed spinal cord resulting from a gunshot wound, traumatic transient paralysis, anterior cord syndrome, lesion of spinal cord, and central cord syndrome Excludes: spinal bone injury (011, 012, or 018) 014 Traumatic injuries to nerves, except the spinal cord This nature group classifies traumatic injuries to nerves other than the spinal cord.
