Coding E Codes Presentation Transcript

  • 1. ICD-9-CM E-codes
  • 2. The basics
    • External cause of injury codes (E codes) provide data for injury research and evaluation of prevention strategies.
    • E codes describe the injury or poisoning by how it happened, the intent (intentional or accidental) and the place where the event occurred.
    • Includes broad categories such as transport accidents, accidental poisonings, suicide attempts, fires, hurricanes, and tornados.
    • E codes are never used as a principal diagnosis and never used alone.
    • Use as additional codes with diagnoses and injuries
  • 3. Look Up
    • Alphabetic Index
      • Separate index that follows Table of Drugs and Chemicals
      • Organized by main terms describing the accident, circumstance, event, or specific agent that caused the injury or adverse effect
  • 4. The Particulars
    • Use of E codes is optional.
    • Place of occurrence:
      • Code E849 is used to identify the place where the event happened.
      • It is never the only E code used.
      • Located in the Alphabetic Index to External Causes under “Accident (to), occurring (at) (in)”
    • E codes for late effects:
      • When the condition being coded is a late effect of an illness or injury, the E code for the late effect must be assigned rather than a current E code.
  • 5. Late Effect E-codes
    • The E codes for external causes of late effects are:
      • E929 Late effects of accidental injury
      • E959 Late effects of self-inflicted injury
      • E969 Late effects of injury purposely inflicted by another person
      • E977 Late effects of injuries due to legal intervention
      • E989 Late effects of injury, undetermined whether accidentally or purposely inflicted
      • E999, Late effects of injury due to war operations and terrorism
    • Late effect E codes are found in the Index to External Causes under ‘Late effect of.”
  • 6. Guidelines for E Codes
    • E codes may be used as additional codes with any code in the categories 001 – V84 to indicate the injury, poisoning, or adverse effect due to external cause.
    • Assign the appropriate E code for all initial treatments of an injury, poisoning, or adverse effect of drugs.
    • Use a late effect E code for subsequent visits when a late effect of the initial injury or poisoning is being treated.
    • Use the full range of E codes to completely describe the cause, intent, and place of occurrence for all injuries, poisonings, and adverse effects of drugs.
  • 7. Guidelines for E Codes (continued)
    • Assign as many E code as necessary to fully explain each external cause.
    • If only one E code can be recorded, assign the one most related to the principal diagnosis.
    • Select the appropriate E code by referring to the Alphabetic Index to External Causes and the Tabular List’s inclusion and exclusion notes.
  • 8. E Codes for Child and Adult Abuse
    • When the cause of an injury is intentional child or adult abuse (995.50 – 995.59, 995.80 – 995.85), the first-listed E code should be assigned from categories E960 – E968, Homicide or injury purposely inflicted by other persons.
    • An additional E code should be used to identify the perpetrator of the abuse.
