Understanding Why Some Procedure Parts Aren’t Covered In-Network

Nothing is more frustrating for patients than receiving care at an in-network facility only to later receive an unexpected bill for a service that wasn’t fully covered by their insurance. Often, these out-of-network charges come as a surprise—especially when patients thought they’d done everything “right” by choosing a hospital or clinic within their plan’s network. But as it turns out, the intricacies of healthcare billing and insurance contracting can create gaps in coverage that catch patients, providers, and even payers off guard.

In-Network Facilities vs. In-Network Providers: Understanding the Difference

An in-network facility simply means that the hospital or healthcare organization has a contractual agreement with an insurance carrier to provide services at negotiated rates. However, within the walls of that facility, numerous independent providers and services may participate—or not—in the same insurance network.

This creates a problem: patients assume that everyone involved in their care is covered, but in reality, different components of a single procedure can be billed separately, often by out-of-network clinicians or departments.

Here’s how this situation commonly plays out:

• Pathology or laboratory services ordered during surgery or an outpatient procedure are billed separately by an external lab that is out-of-network.
• Anesthesiologists, radiologists, and surgical assistants may be contracted independently—not employed directly by the hospital—and may not participate in the same insurance networks.
• The imaging services performed (MRI, CT scan, etc.) at the hospital may be interpreted by an out-of-network radiologist group.

Why Does This Happen?

1. Independent Contracting Structures

It’s important to understand the distinction between a facility and its affiliated providers. For example, a hospital may contract with a group of anesthesiologists, radiologists, or lab services vendors to provide specialized services—but these vendors may not have the same insurance agreements in place. This decentralized structure means a patient might interact with multiple billing entities—each with its own policies and network status.

2. Variability in Insurance Network Participation

Insurance companies negotiate separately with each provider to determine whether they will accept in-network terms. If the contracted payment rates are too low for a specialist’s operating expenses, they may opt to remain out-of-network. This is particularly common among certain high-demand specialist fields like anesthesiology and radiology.

3. Emergency or Unplanned Services

In many cases, patients don’t have a say in which providers deliver certain services. In an emergency room or during surgery, for example, a specialist might be assigned on the spot. If that practitioner is out-of-network, the patient can’t refuse and often doesn’t even know who delivered that aspect of care until the bill arrives.

The Consequences for Stakeholders

Patients

• Unexpected out-of-pocket costs, commonly referred to as “surprise billing” or “balance billing”.
• Increased mental stress and confusion about who is responsible for the charge.
• Reluctance to seek future care out of fear of financial impact.

Providers

• Damage to trust with patients who feel misled, even when the provider had no control over the billing outcome.
• Higher administrative burden in explaining bills and navigating patient dissatisfaction.
• Potential liability or inclusion in lawsuits surrounding surprise medical bills.

Payers (Insurance Companies)

• Pressure from regulatory bodies and consumers to resolve opaque billing practices and disputes.
• Increased scrutiny from state and federal governments regulating network adequacy and transparency.
• Long, complex negotiations and legal battles with providers over reimbursement and out-of-network charges.

What Has Been Done to Address This Issue?

The issue of out-of-network billing for in-network procedures has received national attention in recent years, most notably through legislative efforts like the No Surprises Act, which went into effect in January 2022. This federal law aims to protect patients from surprise medical bills in certain situations, including:

• Emergency services provided by an out-of-network facility or provider.
• Non-emergency services provided by out-of-network providers at an in-network facility.

While the No Surprises Act offers significant protections, there are still gray areas, particularly in how disputes between insurers and providers are resolved and whether all services are covered under its provisions. Patients must still remain vigilant, and providers must take steps to improve communication and transparency.

How Providers and Facilities Can Minimize Confusion and Build Trust

Whether you’re operating a hospital, ambulatory surgery center, or outpatient clinic, it’s crucial to take proactive steps to maintain transparency in your billing practices. Here’s how:

• Perform a network audit: Regularly assess which third-party service providers (radiology groups, anesthesiology teams, pathology labs) are in-network and which are not. Work towards alignment wherever possible.
• Improve pre-service communication: Let patients know in advance if their care will involve out-of-network providers, even at an in-network facility.
• Support patient advocacy: Designate staff or resources to help patients navigate insurance issues and appeal denied claims if surprise bills do occur.

Tips for Patients to Avoid Unexpected Costs

For patients, the key to avoiding surprise bills is asking the right questions before a procedure—when possible. Here are practical steps to take:

• Verify both the facility and individual providers are in-network with your insurance plan.
• Ask about any third-party billing entities involved in your care—such as labs, radiology, or anesthesia groups.
• If unconscious during care (e.g., surgery, emergency), understand your rights under the No Surprises Act.

Conclusion: Navigating a Complicated Ecosystem

The healthcare system is composed of a web of interdependent—but often misaligned—players: insurers, facilities, providers, and most importantly, patients. While federal protections have made progress toward closing the gap between in-network care expectations and actual charges, challenges persist.

Ultimately, fixing these misalignments requires stronger collaboration between all stakeholders. Providers must partner more strategically with insurers and third-party contractors. Health plans need to strengthen their network transparency tools. And patients deserve clear, upfront information that empowers them to make informed decisions. As our industry continues to evolve, prioritizing equity, clarity, and fair billing practices is essential for rebuilding trust and ensuring access to affordable care.
