## ICD-9 Published by WHO

1979

The World Health Organization’s (WHO) International Classification of Diseases, Ninth Revision (ICD-9) replaces the Eight Revision (ICD-8) as the new set of coding rules for reporting mortality data from death certificates.

## ICD-9-CM Implemented in US

1979

The World Health Organization’s (WHO) International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) is developed as the official system of assigning codes to diagnoses and procedures associated with hospital utilization in the United States.

It was adapted from the WHO’s ICD-9 coding system but provided additional details on morbidity coding. ICD-9-CM coding is required by Centers for Medicare and Medicaid Services (CMS) to reimburse for medical claims.

## ICD-10 Published by WHO

1990

The International Classification of Diseases, Tenth Revision (ICD-10) replaces ICD-9 worldwide for reporting mortality data.

## ICD-10-CM Implemented in US

2015

As of October 1, 2015, the US Congress requires the use of the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) for reporting morbidity data. The update to ICD-10-CM allows for efficient tracking of health care and public health trends, monitoring quality of care issues, and evaluating health outcomes. ICD-10-CM provides a greater level of detail, including:

- Identifying the specific side of body involved
- Conveying the complexity of disease conditions
- Providing more precise identification and tracking of specific conditions
- Providing more precise identification and tracking of specific conditions

Diagnosis codes categorize injuries and poisonings by body region and nature of injury. External cause codes provide critical information concerning the nature of injuries, resulting in valuable data for injury research and prevention strategies.

## ISW-9 Report Published

2016

The ninth Injury Surveillance Workgroup (ISW-9) Report is developed by the Safe States Alliance in partnership with the National Center for Injury Prevention and Control, the National Center for Health Statistics, and CSTE.

This report provides guidance for using ICD-10-CM coded data for injury and violence surveillance.

## CSTE ICD-10-CM Workgroup Established

Fall 2016

In the fall of 2016, CSTE develops a workgroup to pilot the case definitions for injury hospitalizations and emergency department visits proposed by CDC’s National Center for Health Statistics and the Center for Injury Prevention and Control.

The workgroup activities include assessing data quality, pilot testing the proposed external cause matrix, creating a validated dataset, and developing standardized case definitions for injury surveillance.

Workgroup members discover a missing group of diagnosis codes that were later amended into the code. Statistics and the Center for Injury Prevention and Control.

## CSTE ICD-10-CM Drug Poisoning Indicators Workgroup Established

Summer 2017

In the summer of 2017, CSTE develops a separate workgroup strictly focused on pilot testing and validating key drug poisoning indicators that would be compatible with ICD-10-CM coding schemes.

The goals of the workgroup are to implement updated and validated Prevention for States/Data Driven Prevention Initiative (PfS/DDPI) overdose morbidity indicators in ICD-10-CM;

build cross-jurisdictional consensus on poisoning indicator definitions in alignment with larger injury surveillance methods;

maximize the sensitivity and specificity of the PfS/DDPI overdose morbidity indicators in ICD-10-CM;

and understand how trend continuity is affected by the ICD-9-CM to ICD-10-CM transition.

## CSTE ICD-10-CM Workgroup Establishes Data Quality Measures​

Spring 2018

Throughout 2017 and early 2018, the CSTE ICD-10-CM Transition Workgroup accomplishes the following:

- Developing data quality measures to identify and calculate key parameters to assess the basic quality of hospital discharge data and emergency department data as they relate to injury surveillance
- Conducting trend analyses from ICD-9-CM to ICD-10-CM of the CDC-proposed ICD-10-CM external cause matrix to identify possible mechanisms and/or intent categories needing further investigation
- Exploring the CDC-proposed ICD-10-CM surveillance case definitions for hospital discharge data and emergency department data to identify and test possible modifications to the case definitions

## CSTE ICD-10-CM Drug Poisoning Indicators Workgroup Continues​

Spring 2018

Throughout late 2017 and into summer of 2018, CSTE ICD-10-CM Drug Poisoning Indicators Workgroup accomplishes the following:

- Developing data quality measures to identify and calculate key parameters to assess the basic quality of hospital discharge data and emergency department data as they relate to injury surveillance
- Conducting trend analyses from ICD-9-CM to ICD-10-CM of the CDC-proposed ICD-10-CM external cause matrix to identify possible mechanisms and/or intent categories needing further investigation
