Frequently Asked Questions
What ICD-11 codes are in Chapter 22?
Chapter 22: Injury, Poisoning or Certain Other Consequences of External Causes covers ICD-11 codes NA00-NF2Z. It contains 28 code blocks with 234 top-level categories.
What conditions does ICD-11 Chapter 22 cover?
Covers fractures, dislocations, sprains, burns, poisonings, and adverse effects of drugs. ICD-11 simplifies the extension code system compared to ICD-10's 7th character approach and provides clearer injury mechanism coding. This chapter includes codes from NA00-NF2Z.
How is ICD-11 Chapter 22 different from ICD-10?
ICD-11 reorganized many chapters compared to ICD-10. Chapter 22 (Injury, Poisoning or Certain Other Consequences of External Causes) may include conditions that were in different ICD-10 chapters, and some conditions previously here may have moved. ICD-11 also adds new chapters for sleep-wake disorders, sexual health, and traditional medicine that did not exist in ICD-10.
How many code blocks are in ICD-11 Chapter 22?
Chapter 22 has 28 code blocks: NA00-NA0Z (Injuries to the head), NA20-NA6Z (Injuries to the neck), NA30-NA3Z (Injury of spinal cord at neck level), NA40-NA4Z (Injury of nerves at neck level), and 24 more.
