February 11, 2022, marked the official release of the International Classification of Diseases, 11th Revision (ICD-11) (2022) for worldwide implementation, with 35 countries already using it (though not in the US yet). ICD is the
international standard
for health data, clinical documentation, and statistical aggregation. The detail provided in ICD-11 codes will allow governments across the globe to propose effective public health policies and measure their impact—a benefit that is front of mind given the ongoing COVID-19 pandemic and an ongoing need to quantify value in healthcare.
Key features
A key component of this iteration of ICD is that it is completely digital, allowing for on- and off-line utilization. The 11th revision of ICD contains over 17,000 diagnostic categories with more than 120,000 medical index terms. The smart coding algorithm interprets over 1.6 million terms. ICD-11 has multilingual browsers, coding tools, and integrated application programming interface (API) tools that facilitate implementation. A translation tool supports international use by ensuring consistent translations.
Use
Some of the reported benefits of ICD-11 include use in:
-
Mortality and morbidity certification, coding, and reporting
-
Researching and performing clinical trials and epidemiological studies
-
Primary care reporting, clinical recording, research, and patient safety
-
Assessing functioning
-
Case-mix and diagnosis-related grouping
-
Coding traditional medicine conditions
-
Assessing and monitoring the safety, efficacy, and quality of care
-
Interoperability standard in WHO digital guidelines and for digital documentation of COVID-19 certificates
-
Cancer registries; grade and stage coding for cancers
-
More efficient clinical documentation
-
Antimicrobial resistance surveillance
-
Updated diagnostic recommendations for mental health conditions
-
Rare disease coding
-
Support for perinatal and maternal coding
To date, the US has not announced transition plans for ICD-11. With ICD-11 only covering diagnosis coding, there is much to be learned regarding how the US will address procedure coding.
