RIS Coding Diagnostic Image Descriptors Rhidian Bramley PACS

RIS Coding & Diagnostic Image Descriptors Rhidian Bramley PACS & Teleradiology SIG BIR, London 2006

Radiology procedure coding • Cluster best practice working groups – London/Southern clusters – NWWM cluster – NE cluster (West Yorks) • RCR PACS SIG coding subgroup – Mapped cluster lists & NHS costing manual – Debated purpose of coding, criteria for procedure inclusion/exclusion & terminology – Developed and endorsed procedure short codes

Procedure Short codes CPEL VB Modality X - X-ray F - Fluoro I - Interventional C - CT M - MRI U - Ultrasound N - Nuc Med P - PET E - Endoscopy Z - Image analysis or review Three or four letter descriptor body part / function code 4 th letter reserved for R, L, B or W if procedure R or L lateralisable, Both or Whole body, otherwise can be used for any letter or number Postqualifier (Extra or subdescriptor)

Procedure Short codes CANKRB Modality X - X-ray F - Fluoro I - Interventional C - CT M - MRI U - Ultrasound N - Nuc Med P - PET E - Endoscopy Z - Image analysis or review Three or four letter descriptor body part / function code 4 th letter reserved for R, L, B or W if procedure R or L lateralisable, Both or Whole body, otherwise can be used for any letter or number Postqualifier (Extra or subdescriptor)

SNOMED CT radiology subset • RCR & NHS Information Authority – Defined subset of radiology procedures (concepts) – Hierarchical structure (grouped by modality) – Post coordination (e. g. laterality) • SNOMED CT Diagnostic Imaging Workshop – Purpose and principles for inclusion of a code in subset – Standard terminology for procedure descriptors • SNOMED CT DI Subgroup – Decision to map SIG/Southern cluster list to SNOMED CT subset, creating new subset concepts

Coding governance relationships and responsibilities LSP or Trusts ? ? ? maintain local list and mapping to SNOMED CT subset NPf. IT, RCR etc ? ? ? maintain SNOMED CT subset Southern/London Cluster List NWWM Cluster List SNOMED CT subset NEEM Cluster List Individual Trust Lists

National SNOMED CT imaging subset coding governance • SNOMED CT Diagnostic Imaging procedures subset management group – NHS Cf. H Terminology service – Royal College Radiologists • Special interest group representation – – – – Society of Radiographers British Nuclear Medicine Society PACS National Clinical Reference Panel Clinical representatives from LSPs Department of Health (national clinical advisor) Representative of secondary uses service Cross border representation?

Revised coding governance relationships and responsibilities Stakeholders SNOMED CT Diagnostic Imaging procedures subset management group Professional Clinical Groups LSP and trust representatives Other Stakeholders Interim ‘mapped’ SNOMED CT representation procedure list SNOMED CT subset

Next steps & challenges • Provide more responsive and timely submission and review process • Incorporate and map to OPCS 4. 3 subset for interventional radiology procedures • Involve special interest groups in line item validation and review of procedure codes • Continue to evolve principles and priorities for population of interim list and SNOMED CT subset • Produce operational procedure notes for specific uses cases e. g. outside imaging review • Firm up relationship to Cf. H governance structures

Sample submissions • Tizzardogram • MRI-Skeletal Survey (Footballer) • MRI-Skeletal Survey (Goalkeeper)
