Description

This logic is intended to extract electronic clinical data. This is not an electronic clinical quality measure and this logic will not produce measure results. Instead, it will produce a file containing the data that CMS will link with administrative claims to risk adjust the Hybrid HWM...

Risk Adjustment

For a detailed description of how the core clinical data elements (CCDEs)are used in the Hybrid HWM measure risk adjustment model, see the Hybrid HWM Measure Methodology Report on CMS.gov here: https://qualitynet.cms.gov/inpatient/measures/hybrid/methodology

Rationale

The intent of this logic is to extract the FIRST valid set of clinical data elements from hospital electronic health records (EHRs) for all qualifying hospitalizations. The data will be linked with administrative claims to risk adjust the Hybrid HWM outcome measure. This work addresses...

Clinical Recommendation Statement

The logic is not meant to guide or alter the care patients receive. The purpose of this CCDE logic is to extract clinical data that are already routinely captured in EHRs from hospitalizations for adult patients. It is not intended to require that clinical staff perform additional...

Improvement Notation

No actual measure score will be generated by hospitals. Instead, hospitals will report the data values for each of the CCDEs for all hospitalizations in the Initial Population. These CCDEs will be linked to administrative claims data and used by CMS to calculate results for the Hybrid...

HWM-Specific Core Clinical Data Elements

Guidance

These specifications are for use for data with discharges that occur between July 1, 2026 and June 30, 2027. The associated Hospital Specific Report (HSR) is anticipated to be released in Spring 2028.

As this is a hybrid outcome measure, the electronic specifications contained within this...

Removed linking variable for National Provider Identifier (NPI) for Medicare Advantage patients to streamline data collection.

Rationale

Measure Lead

Added a supplemental data element to collect information on whether patients were administered oxygen therapy in the 60 minutes prior to an emergency department (ED) encounter or during an ED encounter.

Guidance

Measure Lead

Clarified that the logic extracts the first vital signs and laboratory tests, where the result is not null, during a patient encounter or episode of care.
