Clinical Coding Audit
The need for clinical coding audit
Clinical coding is the process whereby the care given to a patient (usually the diagnostic and procedure information) recorded in the patient notes is translated into coded data (ICD-10 and OPCS-4) and entered into the hospital information system.
Clinical coding staff depend on clear, accurate source information in order to produce a true picture of hospital activity and the care given by clinicians. The coded data is important for a whole range of purposes such as:
- Monitoring provision of health services across the UK
- Research and monitoring of health trends
- NHS financial planning and Payment by Results
- Local and national clinical coding audit
- Clinical governance.
The quality of the data to accurately reflect your hospital activity depends on:
- clear, accurate and timely information provided in the patient notes;
- accurate and consistent clinical coding; and
- good management processes surrounding its collection and processing such as policy and procedures, investment in training and accreditation.
Data validated and audited is most likely to be recognised as a true reflection of hospital activity so establishing regular clinical coding internal audits at your trust ensures a robust data quality cycle.
Clinical coding audit is also an integral part of:
- Information Governance and Requirement 505 for internal clinical coding audit
- Audit Commission Data Assurance Framework which includes independent external clinical coding audits which underpins the Payment by Results and tariff.
