Explain payer mix and two major implications for hospital financial performance.

• A. Payer mix is the distribution of patient revenues by payer (private, Medicare, Medicaid, self-pay); implications: different reimbursement rates affect net revenue and bad debt risk, and government payers often pay less than private payers.
• B. Payer mix is the geographic distribution of patients.
• C. Payer mix determines staffing ratios.
• D. Payer mix is the mix of private and public hospitals in market.

Answer: (A)

Payer mix refers to how hospital revenue is distributed across different payers—private insurers, Medicare, Medicaid, and self-pay. This mix matters because reimbursement rates vary by payer, so shifting toward higher-reimbursing private payers raises net revenue, while more government payers or self-pay lowers it. It also affects collectibility: a higher share of self-pay or underinsured patients increases the risk of bad debt and uncompensated care, hurting cash flow and profitability. In practice, government payers often reimburse at lower rates than private payers, which can further compress margins when the payer mix tilts toward those programs.
