Best practice for encoding some data elements is to use code systems that represent a specific type of information, particularly when the code system is in widespread use. When considering inclusion of data in a measure without a recommended code set, determine whether a specific authoritative code system is in widespread use and consider including that code system in the measure.

Examples

• CDT – Code on Dental Procedures and Nomenclature
• CVX (for vaccines)
• Health Level Seven International® (e.g., Administrative Gender, Discharge Disposition)
• ICF—International Classification of Functioning, Disability, and Health
• NHSN Healthcare Facility Patient Care Location (HSLOC in the Value Set Authority Center [VSAC])
• NUCC – National Uniform Claim Committee
• Source of Payment Typology (National Association of Health Data Organizations [NAHDO])
• UCUM – The Unified Code for Units of Measure
