CMS Measure ID: CMS1074v2    Performance/Reporting Period: 2025    NQF Number: 3663e
Description:

This measure provides a standardized method for monitoring the performance of diagnostic CT to discourage unnecessarily high radiation doses, a risk factor for cancer, while preserving image quality. This measure is expressed as a percentage of CT exams that are out-of-range based on having either excessive radiation dose or inadequate image quality relative to evidence-based thresholds based on the clinical indication for the exam. All diagnostic CT exams of specified anatomic sites performed in hospital inpatient care settings are eligible. This eCQM requires the use of additional software to access primary data elements stored within radiology electronic health records and translate them into data elements that can be ingested by this eCQM. Additional details are included in the Guidance field.

Direct Reference Code

Constrained to 'CT dose and image quality category' LOINC code

QDM Datatype and Definition

"Diagnostic Study, Performed"

Data elements that meet criteria using this datatype should document the completion of the diagnostic study indicated by the QDM category and its corresponding value set.

Timing:

  • relevant dateTime references the time the diagnostic study is performed if it occurs at a single point in time.
  • relevantPeriod references a start and stop time for an assessment that occurs over a time interval:
    • startTime - when the diagnostic study is initiated.
    • stopTime - when the diagnostic study is completed.
  • author dateTime references the time the action was recorded.
  • Refer to the eCQM expression to determine allowable timings to meet measure criterion.

Examples using relevantPeriod:

  • Initiation of a treadmill stress test to the time the treadmill stress test has completed
  • Initiation of the ultrasound study until completion of the ultrasound study

Note: negation rationale indicates a one-time documentation of a reason an activity is not performed. Negation of QDM datatype-related actions for a reason always use the author dateTime attribute to reference timing and must not use relevantPeriod.

Value Set Description from VSAC
Clinical Focus: The purpose of this value set is to represent concepts of inpatient hospitalization encounters.
Data Element Scope: This value set may use a model element related to Encounter.
Inclusion Criteria: Includes concepts that represent an encounter for inpatient hospitalizations.
Exclusion Criteria: No exclusions.

Constrained to codes in the Encounter Inpatient value set (2.16.840.1.113883.3.666.5.307)

QDM Datatype and Definition

"Encounter, Performed"

Data elements that meet criteria using this datatype should document that the encounter indicated by the QDM category and its corresponding value set is in progress or has been completed.

The "Encounter, Performed" participant references the primary participant.

Previous versions of QDM included an attribute principal diagnosis, defined as the condition that, after study, was determined to be the principal cause of the admission. QDM version 5.6 addresses that concept using the diagnosis rank=1.

Timing:

  • The relevantPeriod addresses:
    • startTime - The time the encounter began (admission time).
    • stopTime - The time the encounter ended (discharge time).
  • author dateTime references the time the action was recorded.
  • Refer to the eCQM expression to determine allowable timings to meet measure criteria.

Notes:

  • negation rationale indicates a one-time documentation of a reason an activity is not performed. Negation of QDM datatype-related actions for a reason always use the author dateTime attribute to reference timing and must not use relevantPeriod.
  • The locationPeriod is an attribute of the attribute facility location that addresses:
    • startTime - the time the patient arrived at the location. The time the encounter began (admission time).
    • stopTime - the time the patient departed from the location.
Value Set Description from VSAC
Clinical Focus: n/a Data Element Scope: n/a Inclusion Criteria: n/a Exclusion Criteria: n/a

Constrained to codes in the Ethnicity value set (2.16.840.1.114222.4.11.837)

QDM Datatype and Definition

"Patient Characteristic, Ethnicity"

Data elements that meet criteria using this datatype should document that the patient has one or more of the ethnicities indicated by the QDM category and its corresponding value set.

Timing: Ethnicity does not have a specific timing. Measures using "Patient Characteristic, Ethnicity" should address the most recent entry in the clinical record.

Value Set Description from VSAC
Clinical Focus: Categories of types of health care payer entities as defined by the US Public Health Data Consortium SOP code system
Data Element Scope: @code in CCDA r2.1 template Planned Coverage [act: identifier urn:oid:2.16.840.1.113883.10.20.22.4.129 (open)] DYNAMIC
Inclusion Criteria: All codes in the code system
Exclusion Criteria: none

Constrained to codes in the Payer Type value set (2.16.840.1.114222.4.11.3591)

QDM Datatype and Definition

"Patient Characteristic, Payer"

Data elements that meet criteria using this datatype should document that the patient has one or more of the payers indicated by the QDM category and its corresponding value set.

Timing:

The relevantPeriod addresses:

  • startTime – the first day of insurance coverage with the referenced payer.
  • stopTime – the last day of insurance coverage with the referenced payer.
Value Set Description from VSAC

Constrained to codes in the Race value set (2.16.840.1.114222.4.11.836)

QDM Datatype and Definition

"Patient Characteristic, Race"

Data elements that meet criteria using this datatype should document the patient’s race.

Timing: Race does not have a specific timing. Measures using "Patient Characteristic, Race" should address the most recent entry in the clinical record.

Value Set Description from VSAC
Clinical Focus: Gender identity restricted to only Male and Female used in administrative situations requiring a restriction to these two categories.
Data Element Scope: Gender
Inclusion Criteria: Male and Female only.
Exclusion Criteria: Any gender identity that is not male or female.

Constrained to codes in the ONC Administrative Sex value set (2.16.840.1.113762.1.4.1)

QDM Datatype and Definition

"Patient Characteristic, Sex"

Data elements that meet criteria using this datatype should document that the patient's sex matches the QDM category and its corresponding value set.

Timing: Birth (administrative) sex does not have a specific timing.
