From your article:

> Hospitals are incentivized to diagnose malnutrition by the Inpatient Prospective Payment System, which uses Medicare Severity Diagnosis‐Related Groups to identify a “payment weight.” When severe malnutrition is included on a patient's diagnosis list, a major complication or comorbidity (MCC) classifier is almost always added to the hospitalization claim. 5 Adding an MCC classifier increases reimbursement

If you look at the table, there is almost no relationship between income and likelihood of being marked as a malnutrition case by the hospital receiving reimbursement. (top 25% of income = 20% of cases, bottom 25% of income = 30% of cases).

The median age of these people with severe malnutrition is 70 years old. This is completely consistent with the claim I made around dementia, especially when you consider these people are repeatedly hospitalized oftentimes.
