A lung scan is a general term for a diagnostic imaging procedure used to create pictures of the chest and respiratory system. These scans help physicians diagnose conditions ranging from pneumonia and collapsed lungs to cancer and pulmonary embolisms. There is no single fixed price for a lung scan; the final cost is determined by the specific technology used, the location of the service, and the patient’s health insurance plan. Understanding these variables is the first step toward managing potential out-of-pocket expenses.
Variations in Scan Type and Baseline Cost
The complexity of the imaging technology is the primary factor determining the baseline cost of a lung scan. A simple chest X-ray, which uses a small dose of radiation to capture a two-dimensional image, is the most affordable option. Uninsured patients can expect the baseline price for a chest X-ray to range from approximately $50 to $300, depending on the facility.
A computed tomography (CT) scan is a more advanced procedure that takes multiple X-ray images from different angles to create cross-sectional views of the lungs. The higher technological demands mean that an uninsured CT scan of the chest typically ranges from $300 to $5,000, though costs can exceed this range at some facilities. Low-dose CT scans, often used for lung cancer screening, tend to fall on the lower end of the cost spectrum, sometimes priced around $300 to $500.
The most expensive diagnostic option is a positron emission tomography (PET) scan, often combined with a CT scan (PET/CT) to visualize metabolic activity in the lung tissue. This scan requires the injection of a radioactive tracer, which significantly increases the procedural cost. The average baseline price for an uninsured PET scan of the chest frequently ranges from $1,300 to well over $9,000.
How Facility and Geography Impact Pricing
The type of facility where the scan is performed introduces substantial cost variability, often overshadowing the difference between scan types. Hospital-based outpatient departments typically represent the highest price point for diagnostic imaging services. These facilities have higher operating expenses, including maintenance of emergency services and overhead, which are reflected in their billed charges.
Conversely, independent, freestanding imaging centers generally offer the same quality of diagnostic service at a lower cost. These specialized centers focus solely on outpatient imaging, allowing for a streamlined and cost-efficient operational model. For instance, the same CT scan that may cost $4,750 at a hospital outpatient setting might be priced around $525 at an independent imaging center.
Geographic location also plays a role in pricing due to differences in local market competition and the cost of doing business. Facilities located in major metropolitan areas or regions with a high cost of living tend to charge more for identical services than those in suburban or rural settings. Price differences can be substantial even within the same city, making the choice of location a major determinant of the final bill.
The Role of Insurance in Determining Patient Cost
For patients with health insurance, the out-of-pocket cost is determined by the structure of their specific health plan, not the facility’s sticker price. The deductible is the initial amount the patient must pay annually before the insurance company begins to share the cost of covered services. If the patient has not yet met this amount, they are responsible for the full negotiated cost of the lung scan until the deductible is satisfied.
Once the deductible is met, the patient’s financial responsibility shifts to co-insurance or a co-pay. Co-insurance requires the patient to pay a set percentage of the total negotiated cost (e.g., 20% of the bill), while the insurer pays the remaining 80%. A co-pay is a fixed dollar amount paid at the time of service, though this is less common for high-cost diagnostic imaging.
An insurer’s network status with the facility is another factor influencing patient cost. An in-network provider has a contract with the insurance company to accept a reduced rate for services, guaranteeing lower costs for the patient. Receiving a scan from an out-of-network provider can result in “balance billing,” where the patient is billed for the difference between the provider’s full charge and the amount the insurer pays, although federal protections now limit this practice.
For more complex scans like a CT or PET, insurance plans often require pre-authorization before the procedure is covered. Without this official authorization, the claim may be denied, leaving the patient responsible for the entire cost, regardless of their deductible status. The need for pre-authorization is a mechanism insurers use to ensure the test is medically necessary.
Actionable Strategies for Cost Savings
Patients can take steps to reduce their financial burden for a lung scan, beginning with price shopping before the procedure is scheduled. Since costs vary widely between providers, calling multiple facilities, especially independent imaging centers, to compare their self-pay or cash prices is recommended. When calling, provide the exact procedural code from the referring physician to ensure an accurate quote.
For patients without insurance or those with high-deductible plans, negotiating a cash price can lead to significant savings. Many facilities, particularly freestanding centers, offer substantial discounts (20% to 60%) if the patient agrees to pay the entire bill upfront. This self-pay rate is often lower than the list price billed to insurance companies.
Utilizing healthcare price transparency tools and online estimators can provide useful cost benchmarks for services in a specific geographic area. Always review the final bill for errors, as medical billing is prone to mistakes. Verify that the billed cost aligns with the pre-authorization and the expected co-insurance or co-pay amount.
