ICD 10 is a medical classification system by the World Health Organization. It contains thousands of extremely detailed codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. It is used by all parties in the healthcare system.

Everyone in the industry is well aware of ICD-10 and we've been using it extensively for years. It's only one small piece of the puzzle and not nearly sufficient on its own. Just within the terminology / ontology space most clinical systems will have to support a wide range of others that are mostly orthogonal to ICD-10 such as CPT, RxNorm, LOINC, SNOMED-CT, etc. And that's not even getting into issues with message and document formats.
