      Thank you for your inquiry regarding CMS1074 (Excessive Radiation Dose or Inadequate Image Quality for Diagnostic Computed Tomography (CT) in Adults). We understand you are referencing draft packages posted for vendor review. Please review the answers to your questions below:

      1. The measure developer replaced local codes for each CT category with LOINC Answers to align with QRDA I specifications. In the specific example you reference, LA31752-1 is equivalent to ABDOPEL LD in v1. 64 and 598 correspond to the threshold for the Calculated CT Global Noise in Hounsfield units and the threshold for the Calculated CT Size-Adjusted Dose in dose length product associated with the ABDOPEL LD category. Because CT radiation doses and image noise values are specific to the body part and clinical scenario, each CT category includes unique thresholds.
      2. Singleton from is a CQL language construct to obtain only a single value from a list of values using the criteria provided. A Diagnostic Study, Performed in QDM can have multiple components. Therefore, this definition retrieves the one component that is the global noise component from the Study.

      Hi Team,

      We have a few queries regarding below mentioned functionalities in the measure specification.

      Kindly help us on how to read and interpret them. 

      1) AlaraCommon.CT Scan Qualifies(Study "Diagnostic Study, Performed")

      AlaraCommon.CT Scan Qualifies(Study "Diagnostic Study, Performed")
      "Qualifies"(Study, 'LA31752-1', 64, 598)
        or "Qualifies"(Study, 'LA31753-9', 29, 644)
        or "Qualifies"(Study, 'LA31754-7', 29, 1260)
        or "Qualifies"(Study, 'LA31755-4', 55, 93)
        or "Qualifies"(Study, 'LA31756-2', 32, 576)
        or "Qualifies"(Study, 'LA31758-8', 55, 377)
        or "Qualifies"(Study, 'LA31759-6', 49, 377)
        or "Qualifies"(Study, 'LA31761-2', 49, 1282)
        or "Qualifies"(Study, 'LA31762-0', 115, 582)
        or "Qualifies"(Study, 'LA31763-8', 115, 1025)
        or "Qualifies"(Study, 'LA31764-6', 115, 1832)
        or "Qualifies"(Study, 'LA31765-3', 73, 320)

      If we consider the first value- "Qualifies"(Study, 'LA31752-1', 64, 598). What does 'LA31752-1 stand for? what does 64 and 598 mean?

      2) AlaraCommon.Global Noise Value(Study "Diagnostic Study, Performed")

      AlaraCommon.Global Noise Value(Study "Diagnostic Study, Performed")
      singleton from ( Study.components C
          where C.code ~ "Calculated CT global noise"
            and C.result.unit = '[hnsf\'U]'
          return C.result.value as Decimal
      )
       How to interpret the first line- "singleton from ( Study.components C"
