In the United States, healthcare is already expensive. But what if part of that cost is not about the treatment you receive, it’s about how that treatment is coded?

A major US medical staffing company recently agreed to pay $60 million to settle allegations of fraudulent billing. They were accused of upcoding, a practice where healthcare providers bill insurance companies for more expensive services than were actually performed.

While the legal case may be settled, the larger issue remains very much alive. This is not just a corporate accounting problem. It affects patients, employers, insurers as it distorts trust. And in some cases, it transforms healthcare from a public service into a profit-maximizing system.

What Is Upcoding?

Upcoding is the practice of assigning billing codes that reflect a higher level of service than what was actually provided. Here’s what that looks like in real life:

• A 10–15-minute routine checkup will be billed as a 35-minute complex consultation.
• A mild hospital stay will be coded as high-intensity or critical care.
• A basic service will be classified as a premium one.

Each higher-level code translates into higher reimbursement. And because most patients do not see the detailed coding behind their bills, the practice often goes unnoticed.

Between 2011 and 2019, claims for the highest-intensity levels of care have increased by 41%. Did people suddenly become dramatically sicker during those years? It was not because patients suddenly got sicker, but because billing got smarter and sneakier. Hospitals and healthcare groups increasingly adopted documentation strategies which are designed to maximize reimbursement. The result was billions of dollars in additional payments.

Why Patients Rarely Notice

Medical bills are almost confusing. Most patients see:

• A summary of charges
• An explanation of benefits
• A final amount owed

What they do not see is the underlying code structure that determined the billing amount. Patients are left trying to decode acronyms and unexplained line items. In such an environment, upcoding can operate quietly. When upcoding becomes normalized even subtly, it changes the financial architecture of healthcare.

It is important to clarify that not all expensive bills are fraudulent. Healthcare is complex. Some patients genuinely require high-intensity care.

What Needs to Change?

If we want to address inflated billing, reform must happen at multiple levels.

1. Greater Transparency for Patients

Most patients do not know what medical billing codes mean, and they should not need a degree to read a bill. Patients should receive clear, plain-language explanations that show what service they received, why it was needed and how much it actually costs. Simple billing summaries would help people spot mistakes or charges that do not make sense. When patients understand their bills, they can ask questions, challenge errors and avoid overpaying.

1. Stronger Audit Systems

Insurance companies already collect large amounts of billing data, but it needs to be used more effectively. Modern data analytics tools can identify unusual billing patterns, flag providers who bill far more than others for the same services and catch repeated overcharging early. Both public and private insurers should continue improving these systems, so problems are caught quickly before patients are harmed.

1. Clearer Compliance Standards

Hospitals and staffing companies must follow clear rules about how medical services are billed. They should have internal checks to make sure billing is honest and accurate, not just designed to increase profits. This includes regular internal audits, clear training for staff on ethical billing and accountability when rules are broken.

The Ethical Question

As someone working in the field of health tech, I believe that upcoding is not just a problem with billing systems or insurance rules. At its heart, it is a problem about ethics. Healthcare is built on trust. Patients trust doctors to make decisions that are best for their health. Doctors trust hospitals and healthcare organizations to act honestly. Insurance companies trust that the information they receive is accurate and truthful. When billing is manipulated, even subtly, that trust starts to break down. Over time, these small actions turn healthcare into a business focused more on profit than on people.

When healthcare becomes a financial game, the most vulnerable patients suffer first, those without strong insurance and those who are already burdened by medical debt. Healthcare should never feel like a jackpot for a few and a nightmare for the rest. The next time you open a medical bill and wonder why the cost feels far too high, remember that sometimes it’s not the treatment. It’s the coding behind the scenes.

If you could fix one thing about how hospitals bill patients, what would it be?
