How Government Attempts To Reduce Health Spending Can Paradoxically Raise Health Costs

Why It Matters

The reimbursement gap pushes low‑cost procedures into higher‑priced settings, inflating overall health‑care expenditures and patient out‑of‑pocket costs.

Key Takeaways

• Medicare reimburses $135, clinic cost $194 per lumbar puncture.
• Low reimbursement pushes LPs to radiology, raising overall costs.
• Radiology-performed LPs rose from 11% (1991) to 52% (2018).
• Perverse incentives increase patient out‑of‑pocket expenses.
• Raising clinic LP reimbursement could lower total health‑care spending.

Pulse Analysis

The lumbar puncture, often called a spinal tap, is a cornerstone diagnostic tool for conditions ranging from meningitis to multiple sclerosis. In a typical outpatient setting the procedure requires only a sterile kit and a few minutes of physician time, yet Medicare’s current fee schedule reimburses roughly $135 per case. Clinics, however, report average out‑of‑pocket costs of $194, creating a clear loss margin. When physicians cannot cover basic supplies, the logical business decision is to shift the service to a higher‑priced venue, even if clinical necessity does not demand it.

Data from academic studies illustrate the economic drift. In 1991 radiologists performed just 11 % of lumbar punctures; by 2011 that share climbed to 46.6 % and exceeded 52 % in 2018. The surge aligns with Medicare’s downward pressure on fees, prompting neurologists and other specialists to outsource the procedure to interventional radiology, where fluoroscopic guidance commands higher reimbursement. This reallocation not only inflates total spending—adding imaging, facility, and specialist fees—but also diverts radiologists from higher‑value tasks such as MRI interpretation or complex endovascular work.

Policymakers face a straightforward lever: adjust the outpatient LP fee to reflect true costs. A modest increase could restore clinic viability, reduce unnecessary referrals, and lower aggregate health‑care outlays. Longer‑term, encouraging free‑market entities like the Surgery Center of Oklahoma—where transparent pricing and cash‑based models bypass fee‑setting agencies—offers a parallel pathway to break the perverse incentive cycle. Ultimately, aligning reimbursement with actual service costs is essential to curb wasteful spending and preserve access to efficient, bedside diagnostics.
