      Brief Description of Measure:
      ​CMS249: Appropriate Use of DXA Scans in Women Under 65 Years Who Do Not Meet the Risk Factor Profile for Osteoporotic Fracture:
      Percentage of female patients 50 to 64 years of age without select risk factors for osteoporotic fracture who received an order for a dual-energy x-ray absorptiometry (DXA) scan during the measurement period

      Description of Issue:
      This measure currently uses ​the value set the value set "BMI Ratio (OID: 2.16.840.1.113883.3.600.1.1490)", which contains a single LOINC code. To align with best practices, we propose to replace this single-code value set with the LOINC direct reference code (DRC) of 39156-6, "Body mass index (BMI) [Ratio]". 

      Proposed Solution:

      valueset "BMI Ratio": 'urn:oid:2.16.840.1.113883.3.600.1.1490'

      code "Body mass index (BMI) [Ratio]": '39156-5' from "LOINC" display 'Body mass index (BMI) [Ratio]'


      define "First BMI in Measurement Period":
      ... ["Physical Exam, Performed": "BMI Ratio"] BMI

      ... ["Physical Exam, Performed": "Body mass index (BMI) [Ratio]"] BMI

      Rationale for Change:
      The eCQM Logic and Guidance v5 (May 2021) Section 5.3 states, "the use of direct reference codes prevents using an alternative identifier for a code system concept and eliminates additional implementation work to unpack the value set". 
      Therefore, we propose to replace the value set, "BMI Ratio (2.16.840.1.113883.3.600.1.1490)" with a DRC to align with current best practices.
