Brief Description of Measure:

​CMS153: Chlamydia Screening for Women:
Percentage of women 16-24 years of age who were identified as sexually active and who had at least one test for chlamydia during the measurement period

Description of Issue:

​The value set Sexually Active (OID:2.16.840.1.113883.3.464.1003.121.12.1040) contains a single LOINC code: 64728-9 Have you ever had vaginal intercourse [PhenX].
This does not align with best practices for value set and direct reference code (DRC) management; therefore, we plan to replace this value set with the indicated DRC directly within the logic and terminology section of the eCQM.

Proposed Solution:

Remove value set Sexually Active (OID: 2.16.840.1.113883.3.464.1003.121.12.1040) and replace with LOINC code 64728-9 Have you ever had vaginal intercourse [PhenX]. 

Before:
//Terminology
valueset "Sexually Active" (2.16.840.1.113883.3.464.1003.121.12.1040) 
 
//Logic definition
define "Has Assessments Identifying Sexual Activity":
  exists ( ["Assessment, Performed": "Sexually Active"] SexualActivityAssessment
...

After:
//Terminology:
code "Have you ever had vaginal intercourse [PhenX]": '64728-9' from "LOINC" display 'Have you ever had vaginal intercourse [PhenX]' 
 
//Logic definition
define "Has Assessments Identifying Sexual Activity":
  exists ( ["Assessment, Performed": "Have you ever had vaginal intercourse [PhenX]"] SexualActivityAssessment
...

Rationale for Change:

​​To align with value set best practices, we replaced a single-code value set ("Sexually Active") with a direct reference code.
