NHS ICD-10 Reprinted (with corrections and updates) 2000
The technical preview code list was originally drafted to support a refresh of the ISB 1572 Sensitive Data standards and for no other purpose.
The legal basis for patient identifiable data and sensitive information changed with the introduction of the Health and Social Care Act 2012. However, the legal and policy context and interpretation for sensitive and/or legally restricted data has not been fully established due to the changes in legislation since the original standard was released.
As a result, this supporting code list has remained static since April 2016. NHS Digital will update the codes once an updated policy and instruction is provided by our commissioners.
