SNOMED CT it is not just a coding system of diagnosis
It also covers other types of clinical findings
like signs and symptoms. It includes tens of thousands of surgical, therapeutic and diagnostic procedures
. It includes observables
(for example heart rate), and also includes concepts representing body structures
, pharmaceutical products
, physical objects
, physical forces
and many other types of information that may need to be recorded in or around the health record.
The breakdown of concepts by hierarchy
The comprehensive scope of SNOMED CT reduces the need to support multiple incompatible or overlapping code systems in the same health record system. This means SNOMED CT can become the common terminology for consistent communication, retrieval and processing across clinical specialties and between health care facilities at local, national and international levels.
