Healthcare Costs and Insurance: Navigating the Infectious Disease Maze

At some point, we will all encounter an infectious disease, yet many of us rarely consider the challenges even the simplest treatments can pose. I recently met a patient who had suffered for years with chronic sinusitis. Their condition began during a period when they didn’t have healthcare coverage, and a local clinic refused to see them without a significant upfront cost. Left without options, they bounced between urgent care centers for episodic treatments that eventually stopped working, bringing them to me. This experience instilled a lifelong distrust of healthcare providers, rooted in the humiliation of being denied care in their time of need.

Infectious diseases don’t just impact health—they come with financial burdens that weigh heavily on individuals and the healthcare system. From life-saving antivirals to powerful antibiotics, the high costs of treatment and complicated insurance policies often create insurmountable barriers. This article explores how these challenges affect care and what can be done to improve the system.

Antiviral Therapies: Life-Saving Innovations at a Steep Price

Modern medicine has revolutionized how we treat viral infections, but these breakthroughs come at a cost. HIV medications, for example, have turned a once-fatal disease into a manageable condition. Yet, the lifetime expense of antiretroviral therapy (ART) in the U.S. can exceed $400,000. For patients without Medicaid or those facing high insurance copays, the financial strain can force impossible choices, such as skipping doses or cutting back on necessities like food.

Insurance policies often delay or limit access to newer treatments, requiring “prior authorization” or “step therapy” that forces patients to try less expensive medications first. Doctors and patients alike express frustration with these practices. Although Medicaid and Medicare provide essential coverage, strict eligibility requirements and outpatient medication gaps leave many patients without the support they need. This system, designed to cut healthcare costs, often does the opposite by creating inefficiencies and delays.

Antibiotics and the Resistance Crisis

In the infectious disease world, the rise of multidrug-resistant infections (MDR) highlights the growing challenges of antibiotic use. Resistant bacteria, often caused by overuse and misuse of antibiotics (No, that cold does not require a Z-pak!), are harder to treat, requiring prolonged and costly therapies like intravenous antibiotics. For patients without adequate insurance, these treatments can lead to prolonged hospital stays or suboptimal care options.  

The lack of outpatient coverage for expensive antibiotics often forces patients to remain hospitalized unnecessarily. This can result in complications, reduced quality of life, and skyrocketing costs. For example, imagine grandma hospitalized with a severe urinary tract infection and sepsis who had to stay in the hospital for weeks because her insurance refused to cover the cost of necessary IV antibiotics at home. Prolonged hospitalizations are often associated with significant morbidity for the elderly such as hospital acquired infections, falls and bedsores.   

The Bigger Picture: Costs and Inequities

High healthcare costs and insurance gaps don’t just harm individuals—they weaken public health. Low-income families and communities of color are disproportionately affected, deepening health disparities. When medications become unaffordable, adherence to treatment plans falters, increasing the risk of infection spread and drug resistance. The impact is systemic, creating ripple effects that harm everyone.

Contrary to popular belief, physician reimbursement represents only a small portion of healthcare spending. Administrative costs, particularly in private healthcare, continue to climb, driving public frustration with the system. Learn more here.  The murder of UnitedHealth CEO Brian Thompson earlier this week underscores the public’s anger over inequities in healthcare.

What Needs to Change

Advocacy for affordable medications is critical. Programs like the 340B Drug Pricing Program have made strides, but policymakers must go further to lower drug prices and eliminate access barriers. Expanding Medicaid, closing Medicare coverage gaps, and ensuring private insurance covers essential treatments are necessary steps toward a more equitable healthcare system. On a broader level, incentives for pharmaceutical companies to develop new antibiotics must include mechanisms to keep these drugs affordable. The FDA’s Qualified Infectious Disease Product (QIDP) designation is an example of progress, offering priority review and fast-track approvals for life-saving drugs.

Conclusion

The patient with sinusitis eventually found their cure through several visits and managed care, but many others won’t—held back by financial strain or healthcare denials. The rising costs of infectious disease treatments and systemic inequities in insurance coverage are more than economic problems; they are public health emergencies. Addressing these challenges requires a collective effort from policymakers, healthcare providers, and advocates.
