The Financial Challenge of Geriatric Trauma

Geriatric trauma is becoming a larger part of the trauma center's daily business. The American College of Surgeons (ACS) defines older adults in its geriatric trauma guidance as patients age 65 and older and has specifically recognized the unique vulnerabilities of this population, including frailty, comorbidities, atypical presentations, and increased risk of complications.

Age 65 is also the standard eligibility age for Medicare, a payer that reimburses hospitals through predetermined payment methodologies rather than simply reimbursing the hospital's actual cost of care.

Yesterday's post explored the growing geriatric trauma population and found that the number and proportion of older patients (Medicare patients) is growing. This creates an important question for trauma centers:

As geriatric trauma becomes a larger part of the trauma center's business, do hospitals understand the financial implications of caring for these patients?

The Financial Challenge

Trauma care is expensive. The cost is not limited to the direct care provided to an individual patient. Trauma centers also incur the indirect and readiness costs required to maintain the capacity to care for injured patients 24/7.

Payer mix is therefore an important contributor to the financial performance of a trauma center. In general, commercial payers are more likely to reimburse hospitals at levels that cover the cost of care, while government payers may reimburse according to predetermined payment methodologies.

For Medicare inpatients, payment is based on the Medicare Severity Diagnosis-Related Group (MS-DRG), a predetermined payment for the hospitalization rather than reimbursement of the hospital's actual cost. The Centers for Medicare & Medicaid Services (CMS) describes the inpatient prospective payment system as a fixed-payment system. The American Hospital Association estimates that Medicare reimburses hospitals, on average, at approximately 82% of the cost of caring for Medicare patients, creating substantial financial pressure for hospitals.

This does not mean that every Medicare geriatric trauma admission loses money. It does mean that hospitals may face significant financial exposure when the resources required to care for a patient exceed what is reflected in the predetermined payment. That risk becomes particularly important when an older trauma patient develops complications or experiences a prolonged hospitalization.

When Things Go Wrong, Costs Rise

Older trauma patients often have less physiologic reserve and are more vulnerable to delirium, pneumonia, urinary tract infections, pressure injuries, thromboembolic events, cardiac complications, acute kidney injury, and functional decline. The consequences are clinical -- and financial.

The financial challenge of geriatric trauma is not new. An early study found that DRG reimbursement substantially underestimated the cost of caring for older trauma patients, particularly patients older than 80, patients with severe injuries, and patients who developed multiple complications.

More recent national U.S. data demonstrate the scale of the issue. Between 2012 and 2021, annual inpatient trauma costs increased from $27 billion to $42 billion. Patients aged 75 years and older accounted for 34.8% of trauma costs in 2021, while falls accounted for approximately 70% of trauma costs and Medicare accounted for more than half. (Source)

The issue, therefore, is not simply that geriatric trauma patients are older. It is that a resource-intensive patient population is increasingly being cared for under payment systems that do not necessarily increase reimbursement when resource utilization increases. That creates financial exposure. And complications are one of the biggest drivers of that exposure.

Length of Stay is a Financial Metric

For geriatric trauma, length of stay is not just a throughput metric. It is a financial metric.

Every additional hospital day consumes nursing resources, medications, supplies, laboratory and imaging capacity, therapy, room capacity, and other resources. It also creates additional opportunities for hospital-acquired complications and functional decline.

For Medicare patients, that distinction is particularly important. Because inpatient payment is generally based on a predetermined MS-DRG rather than a per-day payment, the hospital may receive no additional reimbursement for days that extend the hospitalization beyond what the payment accounts for, even though the hospital continues to incur the costs of caring for the patient.

Common causes of potentially avoidable days include:

• Waiting for skilled nursing placement

• Delayed therapy evaluations

• Delayed consultations

• Delayed procedures

• Waiting for imaging

• Delayed medication decisions

• Lack of weekend services

• Family decision-making delays

• Insurance authorization

• Lack of appropriate post-acute capacity

The goal should not be to simply reduce average length of stay. The goal should be to identify avoidable days while preserving appropriate care.

One geriatric trauma program reported that implementation of a multidisciplinary geriatric trauma service reduced average length of stay from 5.64 days to 4.43 days and was associated with a 21.4% reduction in hospital charges during the first five months. (Source)

Where Can Hospitals Improve the Economics?

Hospitals should approach geriatric trauma as a margin-management problem, not simply a reimbursement problem. That means looking for opportunities throughout the patient's episode of care.

1. Prevent Complications

This may be the single most important financial strategy. A geriatric trauma pathway should aggressively address preventable complications through:

• Early delirium prevention and recognition

• Medication reconciliation

• Early mobilization

• Appropriate nutrition

• Pressure-injury prevention

• Pulmonary hygiene

• VTE prevention

• Early identification of swallowing problems

• Avoidance of unnecessary urinary catheters

• Appropriate management of anticoagulation

• Early involvement of geriatrics, hospital medicine, pharmacy, therapy, and other appropriate disciplines

Every complication avoided potentially prevents additional treatment costs, additional hospital days, and additional loss of contribution margin.

The ACS specifically recommends geriatric-focused protocols and multidisciplinary care because older trauma patients have unique risks that may not be apparent from mechanism of injury or traditional trauma assessment alone.

2. Reduce Avoidable Length of Stay

Hospitals should establish geriatric trauma length-of-stay benchmarks and examine why patients remain hospitalized beyond the point at which they require acute hospital care.

The question is not simply: “How do we reduce LOS?”

It is: “Which days are clinically necessary, and which days are avoidable?”

That distinction matters both clinically and financially.

3. Improve Documentation and Coding

In a fixed-payment environment, documentation matters. Comorbidities and complications that meet coding requirements may affect the patient's severity classification and therefore the MS-DRG. Hospitals should evaluate whether clinical documentation accurately captures conditions such as:

• Acute blood loss anemia

• Acute kidney injury

• Acute respiratory failure

• Malnutrition

• Encephalopathy or delirium when clinically supported

• Significant electrolyte abnormalities

• Other documented conditions that meet coding and reporting requirements

This is not about “coding for dollars.” It is about making sure the medical record accurately reflects the complexity of the patient the hospital actually treated.

Make sure the trauma program is capturing every legitimate service and charge it is entitled to report and understand which payers actually reimburse those charges.

4. Use Trauma Activation Charges Appropriately

Revenue code 068X is used to report trauma team activation. But Medicare does not pay the hospital's 068X trauma activation charge. For qualifying outpatient cases (including the ED), Medicare instead makes a predetermined payment associated with HCPCS G0390 when the required criteria are met. For inpatient Medicare admissions, the trauma activation is generally incorporated into the MS-DRG payment rather than paid separately.

The recent HHS Office of Inspector General audit provides an important warning. The OIG estimated that approximately 77% of Medicare claims with trauma team activation during its audit period did not comply with federal requirements, representing an estimated $2.4 billion in unallowable trauma activation charges.

The lesson is not to stop billing trauma activation charges. It is to bill them correctly.

Trauma centers need to ensure that their activation criteria, prehospital notification processes, activation-time documentation, trauma team response, medical record documentation, and billing processes are aligned. Revenue optimization without compliance is not revenue optimization. It is audit risk.

Know the Economics of Your Geriatric Trauma Population

Perhaps the most important question for a trauma center to ask is: “Which geriatric trauma patients generate a negative contribution margin and why?”

Every trauma center should be able to examine its geriatric trauma population by:

• Medicare contribution margin

• Medicare Advantage contribution margin

• Self-pay

• MS-DRG

• Injury type

• Complications

• Length of stay

• Discharge disposition

This analysis may reveal something important. The hospital may not actually be losing money on “geriatric trauma" as a whole, but it may be losing money on specific combinations of: payer + injury + severity + complications + prolonged LOS + discharge disposition.

Understanding these subpopulations offers more actionable findings.

The Bottom Line

Older trauma patients frequently require more resources, have greater clinical complexity, experience more complications, and may have longer or more complicated transitions to post-acute care. At the same time, a significant portion of this population is covered by Medicare, where reimbursement may be based on predetermined rates rather than the hospital's actual cost of care.

That's why hospitals must design geriatric trauma care so that high-quality care and financial sustainability reinforce each other. That means treating complication prevention, length-of-stay management, documentation, coding, charge capture, payer analysis, and contribution margin as components of the trauma program, not separate activities belonging only to finance.

Geriatric trauma is not inherently an unprofitable service line. A financially sustainable geriatric trauma program combines clinical excellence with financial discipline.
