About ICD Codes

ICD Stands for International Classification of Diseases. It is a coding system maintained by the World Health Organization and the U.S. National Center for Health Statistics used to classify causes of death on death certificates and diagnoses, injury causes, and medical procedures for hospital and emergency department visits. These codes are updated every decade or so to account for advances in medical technology. The U.S. has been using the 10th revision (ICD-10) to code causes of death since 1999. The 10th revision of the clinical modification (ICD-10-CM) has been in use for hospital, emergency department, and physician visits starting in October 2015. (1)
There are various versions of the ICD lists. The most commonly used in public health assessment is the ICD code list for underlying causes of death. Selected versions include:

There are hundreds of individual, specific ICD codes. In order to provide a consistent standard for ranking causes of death the NCHS (National Center for Health Statistics) prepared a list of 113 selected causes of death. The NCHS 50 leading causes of death are taken from the list of 113. The 39 selected causes is a separate list for use with small populations. On this page, you'll find all three sets of standard ICD-10 mortality code groupings. Certain other standard groupings of ICD-10 mortality codes, such as the 130 causes of infant mortality, injury mechanism and intent, and drug and alcohol induced deaths, are also commonly used.

For more information about the NCHS cause of death rankings see National Vital Statistics Reports; vol 70 no 9 on the NCHS website.

For information specific to injury ICD codes, visit the IBIS help page on Injury ICD Codes.

Use the "Contents" section at the top to jump to each or the three lists of ICD codes.

NCHS 50 Leading (Rankable) Causes of Death

The NCHS 50 leading causes of death are also known as the 50 rankable causes of death. The list actually includes 52 causes because two causes (COVID-19 and Enterocolitis due to Clostridium difficile) were added in recent years to support surveillance activities when those causes became a concern. ICD-10 was implemented in 1999 for underlying cause of death.

About Injury ICD Codes

ICD codes for injury are grouped by both mechanism (such as poisoning, firearm, fall, and motor vehicle crash) as well as intent, and both mechanism and intent are used in classification. Injuries are classified using five categories of injury intent and typically at least 14 categories used to classify mechanism of injury. Thus an injury death with a mechanism of poisoning may be classified as unintentional (such as an unintentional drug overdose), intentional (homicide), self-inflicted (suicide), legal intervention, or undetermined intent.

The ICD-10-CM codes are for injury are significantly different from the ICD-10 codes for injury mortality. The NCHS categories, above, are known as "underlying causes" of death. Injury mechanism and intent categories are often referred to as "external causes" of death because they refer to the external forces applied to the body. The ICD-10-CM injury diagnosis codes (or nature of injury codes) are the ICD codes used to classify injuries by body region (for example, head, leg, chest) and nature of injury (for example, fracture, laceration, solid organ injury, poisoning).(2)

For more information on injury ICD codes, visit the IBIS help page on Injury ICD Codes.

  1. The NCHS list for mortality uses ICD10 code A16 for respiratory tuberculosis, but in the ICD-10-CM the correct code is A15.
  2. J09 (Influenza due to certain identified influenza viruses) was added to the list of codes for influenza after 2000.
  3. Beginning with 2006, Enterocolitis due to Clostridium difficile was added to the NCHS 50 and 113 lists of causes of death.
  4. Code U07.1 was added for COVID-19 in March 2020.
  5. Code U04 (Severe Acute Respiratory Syndrome, SARS) was added to the mortality ICD10 codes after 2000 but in ICD-10-CM the code is J12.81.
  6. The ICD codes for terrorism are preceded with '*' because they are not used internationally.
  7. Mental health conditions will never be used for an underlying cause of death, but they will be a primary diagnosis in ICD-10-CM.
