ICD-11
WHO's classification for counting disease — fully digital, API-first, with a traditional-medicine chapter India helped shape.
In one line
ICD-11 is the World Health Organization's eleventh International Classification of Diseases — the global standard for mortality and morbidity statistics, billing and reporting, redesigned from scratch as a digital-first product.
How it works
Unlike a terminology (SNOMED records clinical meaning at the point of care), a classification buckets cases for counting: every death and diagnosis lands in exactly one statistical category. ICD-11's modern twist is its architecture — a foundation component (a semantic network of entities) from which linearizations like the mortality/morbidity tabulation are derived, plus post-coordination (cluster codes: stem code + extensions for laterality, severity) and a free API and coding tool instead of a printed book. Chapter 26 covers traditional medicine conditions (TM2), developed with significant Indian input.
Where it shows up in digital health
National health statistics and WHO reporting; insurance claims (India's NHCX rides on standardised coding); registries; and the perpetual mapping task — SNOMED CT→ICD maps let clinicians document once while statisticians count correctly. Many countries are mid-transition from ICD-10; expect both in the wild for years.
