Abstract

Suicide and intentional self-harm are among the leading causes of death in the 

United States. To study this public health issue, epidemiologists and researchers often 

analyze data coded using the International Classification of Diseases (ICD). Prior to 

October 1, 2015, health care organizations and providers used the clinical modification 

of the Ninth Revision of ICD (ICD–9–CM) to report medical information in electronic 

claims data. The transition in October 2015 to use of the clinical modification of 

the Tenth Revision of ICD (ICD–10–CM) resulted in the need to update methods 

and selection criteria previously developed for ICD–9–CM coded data. This report 

provides guidance on the use of ICD–10–CM codes to identify cases of nonfatal suicide

attempts and intentional self-harm in ICD–10–CM coded data sets. ICD–10–CM

codes for nonfatal suicide attempts and intentional self-harm include: X71–X83, 

intentional self-harm due to drowning and submersion, firearms, explosive or thermal 

material, sharp or blunt objects, jumping from a high place, jumping or lying in front 

of a moving object, crashing of motor vehicle, and other specified means; T36–T50 

with a 6th character of 2 (except for T36.9, T37.9, T39.9, T41.4, T42.7, T43.9, T45.9, 

T47.9, and T49.9, which are included if the 5th character is 2), intentional self-harm 

due to drug poisoning (overdose); T51–T65 with a 6th character of 2 (except for 

T51.9, T52.9, T53.9, T54.9, T56.9, T57.9, T58.0, T58.1, T58.9, T59.9, T60.9, T61.0, 

T61.1, T61.9, T62.9, T63.9, T64.0, T64.8, and T65.9, which are included if the 5th 

character is 2), intentional self-harm due to toxic effects of nonmedicinal substances; 

T71 with a 6th character of 2, intentional self-harm due to asphyxiation, suffocation, 

strangulation; and T14.91, Suicide attempt. Issues to consider when selecting records 

for nonfatal suicide attempts and intentional self-harm from ICD–10–CM coded 

administrative data sets are also discussed.

Introduction

Suicide consistently ranks among 

the leading causes of death in the United 

States (1). To address this public health 

issue, the 2012 National Strategy for 

Suicide Prevention, a comprehensive 

long-term plan for suicide prevention 

in the United States, emphasizes the 

importance of data to inform action. The 

plan includes strategic goals to address 

suicide prevention surveillance, research, 

and evaluation activities (2). 

Many of the national systems 

for suicide prevention surveillance 

(3) include data coded using the 

International Classification of Diseases

(ICD) (4). ICD, maintained by the 

World Health Organization, provides an 

international standard for classification 

of diseases and medical conditions. 

Analysts use specific ICD codes to 

identify cases of interest. Over the past 

70 years, multiple revisions have been 

made to ICD. Currently, the United States 

uses the Tenth Revision (ICD–10) for 

classification of deaths, and the clinical 

modification of the Tenth Revision 

(ICD–10–CM) for classification of 

nonfatal events requiring medical 
Page 2 National Health Statistics Reports  Number 108  February 26, 2018

care [e.g., hospitalizations or emergency 

department (ED) visits]. 

While the methods for using 

ICD–10 coded data to study suicide 

deaths are well established (5), the 

use of ICD–10–CM to study nonfatal 

suicide attempts and intentional selfharm is relatively new in the United 

States. Prior to October 1, 2015, health 

care organizations and providers used 

the clinical modification of the Ninth 

Revision of ICD (ICD–9–CM) to report 

medical information when submitting 

electronic claims for administrative and 

financial transactions. With the transition 

to ICD–10–CM in October 2015, 

methods and selection criteria developed 

for use with ICD–9–CM coded data 

need to be updated for use with the new 

ICD–10–CM coding system.

The purpose of this report is to 

provide guidance on the use of 

ICD–10–CM coded data to identify 

events involving nonfatal suicide 

attempts and intentional self-harm. 

This report provides an overview of 

the different types of ICD codes for 

injury (diagnosis codes and external 

cause-of-morbidity codes); the 

differences between ICD–9–CM and 

ICD–10–CM for identifying cases 

involving nonfatal suicide attempts 

and intentional self-harm; and issues to 

consider in developing, testing, and using 

standardized case selection criteria and 

interpreting analysis results. 

Although the focus of this report 

is on the use of ICD–10–CM for 

surveillance of nonfatal suicide attempts 

and intentional self-harm, much work 

has been done on the use of ICD–10–CM 

for injury and violence surveillance in 

general (6–9). These reference materials 

provide additional information on the 

differences between ICD–9–CM and 

ICD–10–CM and the use of ICD–10–CM 

coded data for injury surveillance. 

Injury and Poisoning 

Diagnosis and External 

Cause-of-morbidity 

Codes

The ICD clinical modification 

code sets (e.g., ICD–10–CM) include a 

tabular list of the codes associated with 

different diseases or medical conditions. 

For injury, which includes suicide and 

intentional self-harm, two types of codes 

are important: injury diagnosis codes and 

external cause-of-morbidity codes. 

● Injury diagnosis codes provide 

information about the nature of 

injury (e.g., fracture; strains and 

sprains; and injury to blood vessels, 

nerves, and internal organs) and the 

body region involved [e.g., head 

and neck, torso, abdomen, upper 

extremity (arm), and lower extremity 

(leg)]. In ICD–9–CM, injury and 

poisoning diagnosis codes broadly 

include codes 800–999; in 

ICD–10–CM, these are codes 

S00–T88 (10,11). 

● External cause-of-morbidity codes 

provide information about the 

mechanism of injury (e.g., fall; 

poisoning; exposure to fire, flames 

or hot substance; and cutting or 

piercing) and intent of injury 

(e.g., unintentional, intentional 

self-harm, assault, and undetermined 

intent). In ICD–9–CM, external 

cause-of-morbidity codes broadly 

include codes E000–E999; in 

ICD–10–CM, these are V, W, X, and 

Y codes and some T codes. 

Although both types of codes are 

useful for understanding different aspects 

of an injury event, external cause codes 

are particularly important for studying 

suicide and intentional self-harm.

Differences Between 

ICD–9–CM and 

ICD–10–CM Codes for 

Suicide Attempt and 

Intentional Self-harm

In ICD–9–CM, the external cause 

codes E950–E959 identify events 

involving suicide attempt and intentional 

self-inflicted injury. A detailed list of the 

codes and their descriptions is provided 

in the Technical Notes. Although 

researchers are often interested in 

distinguishing between different types of 

self-directed violence (12), the external 

cause codes in ICD–9–CM do not 

differentiate between events involving 

intentional self-inflicted injury with 

intent to die (i.e., suicide attempt) and 

events where the self-inflicted injury was 

intentional but there was no intent to die 

(i.e., intentional self-inflicted injury). 

The same subset of ICD–9–CM external 

cause codes (E950–E959) is used for 

both types of events. 

The codes for suicide attempt 

and intentional self-inflicted injury in 

ICD–10–CM differ from ICD–9–CM in 

several ways. First, the label “suicide 

attempt and self-inflicted injury” used 

in ICD–9–CM has been changed to 

“intentional self-harm” in ICD–10–CM. 

As with ICD–9–CM, codes related to 

“intentional self-harm” do not distinguish 

between events that were intended to be 

fatal (i.e., suicide attempt) and events in 

which the self-harm was intentional but 

there was no intent to die. 

Second, in contrast to ICD–9–CM 

where suicide attempt and self-inflicted 

injury are identified exclusively by 

external cause codes, in ICD–10–CM, 

some of the codes that identify suicide 

attempt and intentional self-harm are 

external cause codes (X71–X83) and 

some are diagnosis codes (specific 

T codes). In ICD–10–CM, several injury 

mechanisms (e.g., drug poisoning, toxic 

effects of nonmedicinal substances, and 

asphyxiation) are assigned an injury 

diagnosis code (T36–T50, T51–T65, and 

T71, respectively) rather than an external 

cause code. For these mechanisms, 

information about the intent of the 

injury (unintentional, intentional selfharm, assault, and undetermined intent) 

is captured in a character within the 

code. For example, T42.4X1 identifies 

unintentional (accidental) poisoning 

by benzodiazepines, whereas T42.4X2

identifies poisoning by benzodiazepines 

from intentional self-harm. 

The relevant ICD–10–CM injury 

diagnosis and external cause codes for 

suicide attempts and intentional self-harm 

are summarized in the Table. 

In ICD–10–CM:

● External cause codes X71–X83 

identify intentional self-harm due to 

all mechanisms other than poisoning 

and asphyxiation. In addition to 

the external cause code, an injury 

diagnosis code (an S or T code) is 

also assigned to describe the type of 
National Health Statistics Reports  Number 108  February 26, 2018 Page 3

anatomic or physiologic injury that 

occurred. 

● Drug poisonings (overdoses) are 

captured using diagnosis codes 

T36–T50. The intent of the 

drug poisoning (overdose) (i.e., 

unintentional, intentional self-harm, 

assault, or undetermined intent) 

is generally captured in the 6th 

character of the code. For a few 

codes as noted in the Table, the intent 

is captured in the 5th character of the 

code. A 6th character (or when

applicable, a 5th character) of 2 

indicates that the drug overdose 

resulted from intentional self-harm. 

For example, T42.3X1 identifies 

unintentional (accidental) poisoning 

by barbiturates, whereas T42.3X2

identifies poisoning by barbiturates 

from intentional self-harm. 

● Toxic effects of nonmedicinal 

substances (e.g., alcohol, organic 

solvents, corrosive acids and alkalis, 

metals, carbon monoxide and other 

gases, pesticides, and ingestion of 

toxic plants) are captured using 

diagnosis codes T51–T65. As 

with drug poisoning, information 

regarding intent is generally captured 

in the 6th character of the code. For 

a few codes as noted in the Table, 

the intent is captured in the 5th 

character of the code. A 6th character 

(or when applicable, a 5th character) 

of 2 indicates that the drug overdose 

involved intentional self-harm.

● Asphyxiation includes such 

mechanisms as mechanical 

suffocation, hanging, and other 

means resulting in systemic oxygen 

deficiency. Intentional self-harm 

from asphyxiation is captured using 

the diagnosis codes of T71 with a 

6th character of 2.

● T14.91 is a diagnosis code that is 

assigned when the injury event was 

known to be a suicide attempt but 

information is insufficient to specify 

the type of injury or the specific 

means involved in the event. 

The codes listed in the Table 

are consistent with the assignment 

of intentional self-harm codes in the 

proposed ICD–10–CM external cause 

matrix (7). The proposed ICD–10–CM 

external cause matrix was developed 

jointly by the National Center for Health 

Statistics and the National Center for 

Injury Prevention and Control to provide 

a framework for consistent reporting of 

injury by mechanism and intent across 

time and from jurisdiction to jurisdiction. 

The codes in the Table are injury 

diagnosis or external cause codes that 

specifically identify injuries resulting 

from intentional self-harm. Other 

ICD–10–CM codes not included in 

the Table that may be of interest to 

researchers studying suicide- or selfharm-related concepts include R45.851, 

Suicidal ideation; Z91.5, Personal history 

of self-harm; and a subset of F codes 

that describe mental, behavioral, and 

neurodevelopmental disorders (found in 

Chapter 5 of ICD–10–CM). These codes 

are not included in the Table because they 

do not identify injuries resulting from 

intentional self-harm. 

A detailed list of the ICD–10–CM 

codes and their descriptions is provided 

in the Technical Notes.

Issues to Consider 

in Developing a 

Surveillance Case 

Definition for Nonfatal 

Suicide Attempt and 

Intentional Self-harm 

Hospitalizations and 

ED Visits

Standardized surveillance case 

definitions provide uniform criteria for 

case selection, allowing for comparison 

of results generated from different data 

sets and across time (12). Although the 

identification of the appropriate 

ICD–10–CM codes is an important first 

step, there are other issues to consider 

when developing an operational 

surveillance case definition for suicideattempt and intentional self-harm 

hospitalizations and ED visits and when 

interpreting results from analyzed data. 

Some of these issues are discussed below. 

Issues related to 

documentation and coding

● The assignment of ICD–10–CM 

codes is based on how events and 

conditions are documented in the 

medical record (13). However, 

the way findings are documented 

may vary based on a clinician’s 

experience and interpretation of a 

given patient’s presentation. Use 

of standard clinical case definitions 

may vary from clinician to clinician 

or facility to facility. In the case 

of suicide attempt or intentional 

self-harm, concern by the patient on 

their own behalf, or by the clinician

T64.8, and T65.9, which are included if the 5th character of the code = 2)

Asphyxiation, suffocation, hanging T71 with the 6th character of the code = 2

on the patient’s behalf, about the 

stigma that might result if an event 

is recorded a particular way may 

influence how the event is described 

in medical documentation. If the 

medical record does not provide 

sufficient supporting documentation, 

an ICD–10–CM code for intentional 

self-harm might not be assigned.

● Administrative data sets for 

hospitalizations and ED visits can 

vary in the completeness and quality 

of ICD coding, particularly with 

regard to external cause codes. 

Federal mandates require health 

care providers to include diagnosis 

codes when submitting electronic 

claims for reimbursement; however, 

there is no requirement to report 

external cause codes. Despite the 

lack of a federal requirement, 

some states have specific state 

mandates regarding the reporting of 

external cause codes, while in other 

states, reporting is voluntary (14). 

Additionally, certain health systems 

or facilities may have policies 

that require external cause coding, 

and some electronic health record 

(EHR) systems prompt, or even 

require, entry of an external cause 

code when an injury or poisoning 

diagnosis is assigned. These factors 

have resulted in state-to-state and 

facility-to-facility variations in the 

completeness of external cause 

coding. The Agency for Healthcare 

Research and Quality (AHRQ) 

routinely measures the percentage of 

injury hospitalizations and ED visits 

that also have an external cause code. 

In 2013, AHRQ estimated that more 

than 90% of injury hospitalizations 

and ED visits across the country 

had been assigned an external cause 

code, although the percentage varied 

by state (15). A Healthy People 2020 

objective focuses on increasing the 

percentage of states (and the District 

of Columbia) with statewide hospital 

discharge data systems that routinely 

collect external cause of injury codes 

for 90% or more of injury-related 

discharges (16). Several reports 

have provided recommendations on 

improving external cause coding in 

state-based hospital discharge and 

ED data systems (17,18). 

Because external cause codes 

are essential for identifying cases 

involving suicide attempts and 

intentional self-harm, it is important 

to know the completeness of external 

cause coding in the data set used 

for analysis. If a high proportion of 

injury records lack an external cause 

code, the counts of cases involving 

suicide attempts and intentional 

self-harm could be underestimated 

(19,20).

● Information on both the mechanism 

and the intent of the injury or 

poisoning is needed to appropriately 

assign an external cause code. 

Injury events can be unintentional 

(accidental) or involve intentional 

harm to oneself or intentional harm 

inflicted by another person. When the 

intent of the injury is not known or 

not well documented in the medical 

record, codes for undetermined intent 

may be assigned. 

In ICD–9–CM, the official 

coding guidelines from the Centers 

for Medicare & Medicaid Services 

state that if the intent of the cause of 

an injury or poisoning is unknown 

or questionable, the intent should 

be coded as undetermined (codes 

E980–E989) (21). In contrast, in 

ICD–10–CM, the official coding 

guidelines state that if the intent of 

the cause of an injury or poisoning 

is unknown or unspecified, the intent 

should be coded as unintentional; 

external cause codes for events of 

undetermined intent are only for use 

if the documentation in the record 

specifies that the intent cannot be 

determined (13).

In analyzing administrative 

data, both the overall completeness 

of external cause coding and the 

proportion of injury and poisoning 

records that have been assigned 

codes for undetermined intent 

should be determined. If a high 

proportion of injury cases were 

assigned external cause codes for 

undetermined intent, the counts of 

cases involving suicide attempts 

and intentional self-harm (as well 

as the other intent categories—

unintentional and assault) could be 

underestimated.

Issues related to case 

selection criteria

● Claims and EHR data typically 

contain multiple fields for capturing 

ICD–CM codes associated with 

a given hospitalization, ED visit, 

or other health care event. In 

hospitalization records, the first code 

listed is considered the principal 

diagnosis (i.e., the diagnosed 

condition that resulted in the patient 

being admitted for care). For fields 

other than the principal diagnosis 

field, there are no national standards 

or practices for the order in which 

the codes are assigned, other than 

those dictated by the sequencing 

instructions in the ICD–CM

classification. Some injury case 

definitions are based on the principal 

diagnosis only (6), while others 

take an “any mention” approach. 

To capture all suicide attempt 

or intentional self-harm events, 

researchers might consider including 

records with any mention of an 

ICD–10–CM code related to suicide 

attempt or intentional self-harm, 

regardless of coding position or 

order, rather than limiting selection 

to principal diagnosis only. 

● The injury diagnosis and external 

cause codes in ICD–10–CM include 

a 7th character that provides 

information on the type of medical 

care encounter involved (11). The 

character for type of encounter 

identifies whether the injury 

diagnosis is related to an initial 

encounter (when the patient is 

receiving active treatment for the 

condition), a subsequent encounter 

(encounters for routine care during 

the healing or recovery phase 

after the active treatment phase 

has ended), or sequelae of injury 

(complications or conditions that 

arise as a direct result of an injury). 

A 7th character of A, B, or C on a 

diagnosis code is used to identify 

an initial encounter; a character 

of D through R is used to identify 

a subsequent encounter; and a 

character of S is used to identify 

sequelae of an injury. The specific 

letter assigned varies by diagnosis 

code. The 7th character is required 
National Health Statistics Reports  Number 108  February 26, 2018 Page 5

for all S codes and all T codes 

except T30–T32, and for all external 

cause codes (the 7th characters 

for external causes include A for 

initial encounters, D for subsequent 

encounters, and S for sequelae). 

In developing an ICD–10–CM 

surveillance case definition for 

suicide attempts and intentional 

self-harm, consideration should be 

given to the types of encounters 

(initial, subsequent, or sequelae) to 

include (e.g., all or only a subset). 

Issues related to testing a 

proposed case definition

● In developing a surveillance case 

definition for hospitalizations and 

ED visits for suicide attempts and 

intentional self-harm, consideration 

should be given to testing the ability 

of the surveillance case definition 

to identify true cases. One possible 

testing method involves reviewing 

medical records that were selected 

using the surveillance case definition 

to determine whether the record 

reflects a “true” hospitalization 

or ED visit for suicide attempt or 

intentional self-harm. Details on 

conducting a medical record review 

have been described elsewhere 

(9,22–25). The findings from the 

medical record review could be 

used to determine the sensitivity, 

specificity, and positive predictive 

value of a proposed case definition.

● To look for possible “missed” 

cases, researchers might consider 

determining the number of records 

that: a) have an injury or poisoning 

diagnosis code other than the 

T codes listed in the Table, b) have 

code R45.851, Suicidal ideations, 

and c) do not have an external 

cause code. Records identified 

using these criteria might represent 

potential suicide attempts and 

intentional self-harm cases not 

identified by selecting records solely 

by using the recommended codes 

in the Table. Records identified 

by this method would need to be 

reviewed to determine whether they 

truly involved suicide attempt or 

intentional self-harm events. 

Other considerations

● Surveillance case definitions 

developed for use with 

administrative data based on the 

Universal Billing Form (UB–04) 

might not be directly applicable 

to other data sets (e.g., syndromic 

surveillance, paramedic trip 

reports, and physician’s office 

visits). Additional validation and 

testing may be required when 

applying a surveillance case 

definition developed for use with 

administrative data to other data sets. 

● The completeness of external cause 

coding is an important consideration 

when interpreting analysis results. As 

mentioned earlier, there is no federal 

mandate for reporting external 

cause codes in administrative data. 

In studying hospitalizations and 

ED visits for suicide attempt and 

intentional self-harm using 

ICD–9–CM, the incompleteness of 

external cause coding theoretically 

affected all mechanisms equally 

because suicide and intentional 

self-harm cases were identified 

exclusively based on external cause 

codes. In contrast, in analyses 

of ICD–10–CM coded data, the 

possibility exists that mechanisms 

other than poisoning and 

asphyxiation will be undercounted 

because they are identified using 

external cause codes (which are not 

required for reimbursement), while 

suicide attempts and intentional selfharm by drug poisoning, poisoning 

from nonmedicinal substances, 

and asphyxiation are identified 

using diagnosis codes (which are 

required for reimbursement). These 

differences should be considered 

when comparing results from 

analyses of data coded in ICD–9–CM

to data coded in ICD–10–CM, 

particularly when reporting the 

number or proportion of cases by 

the type of mechanism or means of 

suicide attempt or intentional selfharm involved. 

Conclusions

Data coded using the International 

Classification of Diseases (ICD) 

are routinely used for public health 

surveillance, to conduct research on risk 

factors and health care utilization, and 

to evaluate prevention programs. The 

transition in October 2015 to the use of 

ICD–10–CM by health care organizations 

and providers to report medical 

information in administrative claims 

data has resulted in the need to update 

previous ICD–9–CM-based definitions 

and case selection criteria to identify 

specific events (e.g., hospitalizations and 

emergency department visits) of interest. 

This report discusses issues to 

consider in the development of a 

surveillance case definition for nonfatal 

suicide attempts and intentional self-harm 

using the ICD–10–CM coding system. 

The increased complexity and level 

of detail in ICD–10–CM has resulted 

in systematic changes in how events 

involving nonfatal suicide attempt and 

intentional self-harm are identified. The 

information and issues highlighted in this 

report will help the injury research and 

practice community make the transition 

to the use of ICD–10–CM coded data 

to conduct surveillance and research on 

nonfatal suicide attempts and intentional 

self-harm. However, in developing any 

given case definition, the sensitivity 

and specificity of the definition should 

be considered, as these characteristics 

measure the accuracy and usefulness 

of the definition in practice (22–25). 

Additionally, comparability to historical 

trends using ICD–9–CM coded data 

should be assessed. Changes in the 

numbers and rates that occur after the 

implementation of the ICD–10–CM 

coding system should be explored, and 

the factors contributing to the change 

should be understood (26,27).
