National clinical coding standards

This title gives specific instruction on the use of the ICD-10 classification for morbidity coding in areas of potential ambiguity to safeguard data consistency through national clinical coding standards. The National Clinical Coding Standards ICD-10 are for use with the World Health Organisation (WHO) International Statistical Classification of Diseases and Related Health Problems, Tenth Revision 5th Edition (ICD-10) when translating diagnoses and other health related problems recorded in a patient's medical record for morbidity coding. The classification of diagnoses using ICD-10 is a mandatory national requirement for the NHS Admitted Patient Care (APC) Commissioning Data Set. Where a standard within the WHO ICD-10 Volume 2 differs to a national clinical coding standard, the national clinical coding standard must take precedence.
