Frequently Asked Questions

What ICD-11 codes are in Chapter 23?

Chapter 23: External Causes of Morbidity or Mortality covers ICD-11 codes PA00-PL2Z. It contains 81 code blocks with 570 top-level categories.

What conditions does ICD-11 Chapter 23 cover?

Supplementary codes describing the cause of injury or adverse event, such as transport accidents, falls, assaults, and accidental poisonings. ICD-11 modernizes external cause classification with simplified coding for mechanism and intent. This chapter includes codes from PA00-PL2Z.

How is ICD-11 Chapter 23 different from ICD-10?

ICD-11 reorganized many chapters compared to ICD-10. Chapter 23 (External Causes of Morbidity or Mortality) 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 23?

Chapter 23 has 81 code blocks: PA00-PA0Z (Unintentional land transport road traffic injury event), PA00-PA5Z (Unintentional transport injury event), PA00-PB6Z (Unintentional causes), PA10-PA1Z (Unintentional land transport off-road nontraffic injury event), and 77 more.
