CMS Global Malnutrition Composite Score: Are You Ready to Report?

April 26, 2023

Nutrition care matters — and the healthcare industry is taking notice. That’s why, last year, the Centers for Medicare and Medicaid Services (CMS) adopted the Global Malnutrition Composite Score (GCMS) electronic clinical quality measure (eCQM) into its Hospital Inpatient Quality Reporting program. 

The goal is clear: to help improve outcomes by devoting more attention to patients’ nutritional needs and related social determinants of health — particularly for those most at risk for nutritional deficiency and food insecurity. 

While the reporting will be voluntary, CMS is keen to have this data — and for good reason. One in three hospitalized patients in the US are malnourished or at risk, yet less than 8.9% are officially diagnosed.¹ This frequently missed diagnosis negatively impacts patient outcomes and drives up the cost of care. And it affects many of your most vulnerable populations, including those over 65 years of age.² 

What Goes Into the GMCS Measure?  The measure consists of four key components: 

1. Screening
Screen for malnutrition risk at admission.

2. Nutrition Assessment
Complete nutrition assessments for patients identified as at-risk for malnutrition.

3. Document Malnutrition Diagnosis
Appropriately document malnutrition diagnoses for patients identified with malnutrition.

4. Develop Nutrition Care PlanDevelop a nutrition care plan for malnourished patients, including recommended treatment plan.

Why Should You Start Preparing to Report Malnutrition Data Now? 

The GMCS reporting period begins in January 2024, but many hospitals are already beginning preparations. Here are a few steps you can take now to prepare: 

Assess Your Readiness
Do you have the data you’ll need? How easy is it to access? How could the process be streamlined?

Enhance Your EHR
If nutrition care isn’t adequately documented today, investigate options to improve documentation without overburdening your dietitians or physicians.

Do a Data Quality Check
Consult with clinical teams, nutrition teams and CDI teams. If you’re seeing frequent denials relating to malnutrition, now is the time to get to the root cause.
