Author Description

The OPCS Classification of Interventions and Procedures (OPCS-4) is a statistical classification of interventions and procedures undertaken in the National Health Service (NHS) reflecting current clinical practice. OPCS-4 is an approved NHS Fundamental Information Standard. This reference book of national clinical coding standards is an evolving product and builds on the previously issued OPCS-4 Clinical Coding Instruction Manual. As the main emphasis of clinical coding is data quality and accuracy this reference book will focus on the clinical coding standards that must be applied when assigning OPCS-4 codes.
