Strategies to capture value in uncompensated care for hospitals

Hospital care that goes unpaid can be a significant financial challenge for health systems today. Uncompensated care (UCC), which refers to hospital services provided to patients for which no payment is received, has been on a steady rise over the last several years. But with the right guidance and tools, financially strained providers can find reimbursement solutions for uncompensated care.

Hospitals across the United States accumulated over $36 billion per year in uncompensated care costs over the last three years according to the Federal Fiscal Year 2026 proposed rule published by the Centers for Medicare and Medicaid Services (CMS). As providers navigate UCC processes and changes in UCC payment pools, they have options for reimbursement opportunities:

  • Medicare Worksheet S-10/UCC use
  • Medicare bad debt provisions
  • State indigent care pool reporting
  • Cost reporting strategies

Here are a few scenarios that illustrate the solutions that are available to providers seeking reimbursement for uncompensated care and the benefits, or drawbacks, of each. The scenarios show the compensation that providers can expect in a patient account with $100,000 in unpaid charges.

Scenario A. Uninsured discount

Assumptions

  • $100,000 in unpaid charges
  • 50% uninsured discount
  • 25% cost-to-charge ratio
  • Uninsured or self-pay patient

For patients who meet the specified criteria in a provider’s financial assistance, charity care or uninsured discount policies, their accounts can be written off from active accounts receivable and included for UCC reporting on Medicare Cost Report Worksheet S-10. Remember, however, that the reimbursement will not cover the actual charges. In this example, $50,000 ($100,0000 in unpaid charges multiplied by the 50% uninsured discount, as noted above) is written off to a financial assistance adjustment or uninsured discount. This translates to $12,500 ($50,000 write-off multiplied by 25% cost-to-charge ratio) of uncompensated costs, and the estimated reimbursement from the Medicare UCC pool would be $2,250, or approximately 18% of the uncompensated costs or 2.25% of unpaid charges. The 18% and 2.25% are not regulatory determined amounts but estimates based on UCC payment pools and years of experience. This reimbursement is distributed over three years of UCC payments, so collection may take time.

Scenario B. Presumptive charity care

Assumptions

  • $100,000 in unpaid charges
  • 100% presumptive charity discount
  • 25% cost-to-charge ratio
  • Uninsured or self-pay patient

Presumptive charity care can be useful for reducing costs borne by providers and patients. While reimbursement for these accounts may still takes time, as it comes through the same UCC payments as mentioned in the first example, there is less risk that a portion of the unpaid charges will go unaccounted for if patients are eligible for a full presumptive charity discount. The costs in this example are $25,000 ($100,000 in unpaid charges multiplied by the 25% cost-to-charge ratio,) which produces estimated UCC reimbursement of $4,500 (approximately 18% of costs or 4.5% of unpaid charges). There are also potential cost savings.  Since the account was presumed to be charity care, the cost of collection was removed as patient bills were not sent, collection agencies were not involved, and the labor cost for helping patients apply for financial assistance was eliminated. Additionally, supplemental state Medicaid payments may be available related to uninsured accounts that receive presumptive charity adjustments.

The difference between the 2.25% and 4.5% UCC reimbursement for unpaid charges is due to the 50% uninsured discount in Scenario A versus the 100% presumptive charity discount in Scenario B.

Scenario C. Medicare bad debt

Assumptions

  • $20,000 in total charges
  • $10,000 Medicare payments
  • $5,000 Medicare contractual
  • $5,000 patient responsibility (deductible, coinsurance, copay)

For Medicare accounts, Medicare bad debt is a preferred avenue of reimbursement as these are paid at 65% of charges, rather than the less than 20% of costs received for an insured charity care account reported on Worksheet S-10. Medicare bad debts are, however, subject to more stringent regulations. These include restricting claimed amounts to just the patient’s responsibility (Medicare deductible, coinsurance, copay) and the requirement that providers should wait at least 120 days from the date the patient is billed to consider an account uncollectible. The benefits here can be seen in both the reimbursement timing and amount. The estimated reimbursement in this example would be 65% of the $5,000 patient responsibility, or $3,250. This compares to just $900 ($5,000 multiplied by the 18% reimbursement estimate) if claimed as insured charity care on Worksheet S-10 and would be received through bi-monthly pass-through payments rather than three years of UCC payments.

While there are various other reimbursement opportunities for Medicare providers to explore, these examples highlight the importance of capturing and reporting accounts in the correct way.

What should health systems do now?

Health systems can explore several strategies to improve the reimbursement they receive for uncompensated care.

  • Review your health system's financial assistance policy checking for presumptive charity eligibility, self-pay discounts, and how these have been implemented.
  • Perform a lookback analysis on your hospital’s Worksheet S-10 uncompensated care listings to confirm all accounts are properly being captured.
  • Investigate your home office cost report allocation methodologies to check for reliable cost allocations impacting the hospital's cost to charge ratio.
  • Perform a lookback analysis on your hospital’s Medicare bad debt filings. Each year Medicare bad debt reimbursement is under the microscope to be reduced to save trust fund dollars so capturing this reimbursement while it is still available is important for hospitals.
  • Check your state’s Medicaid program and potential uncompensated care pools to confirm state filings are properly capturing uncompensated care costs.
  • As artificial intelligence (AI) continues to evolve there are growing opportunities to incorporate AI into uncompensated care modeling.
