The statement regarding DRG 191 that is true is that the payment is higher for patients assigned to this DRG. Diagnosis-related groups (DRGs) categorize inpatient stays into groups that are expected to have similar hospital resource use. DRG 191 typically pertains to a specific type of surgical or medical procedure that incurs higher costs, leading to higher reimbursement rates from payers.

In the context of Medicare and other insurance payment systems, the payment amount for DRGs is determined by the complexity and cost of treating conditions related to that DRG. Therefore, a higher payment indicates that patients assigned to DRG 191 likely require more intensive resources, such as extended hospital stays, specialized treatments, or both.

While it may be the case that more patients are diagnosed with DRG 191 or that the case-mix index could be influenced by higher volumes of certain DRGs, these factors do not specifically address the payment structure linked to this DRG. Additionally, although the case-mix index reflects the diversity and resource intensity of patient care, a static case-mix index would not provide insights that contradict the adjusted payments based on the resource use associated with DRG 191.
