Cutting corners: why accessibility overlays are a liability to medical websites
Accessibility overlays are a cosmetic, legally indefensible shortcut that puts medical practices at greater risk of ADA lawsuits, privacy violations, and patient safety issues, making proper code-level remediation the only reliable path to WCAG 2.1 AA compliance.
“First, do no harm.” This is fundamental to medical professionals. As a medical professional, you are inherently committed to this principle. This applies to all aspects of your practice, including your website and scheduling tools. Literally, every aspect of your practice that the public can potentially interact with.
The pressure to meet the Americans with Disabilities Act (ADA) requirements has led many medical professionals to seek shortcuts in adopting so-called ‘accessibility overlays’.
Often marketed as a one-click solution, these automated tools often appear as a small icon in one of the lower corners of a website. These tools promise to instantly remediate potential accessibility issues on your website. Unfortunately, multiple recent legal precedents and technical realities expose a different story. These overlays are not only sufficient for ADA compliance but can also increase your risk of litigation.
The Compliance Standard: WCAG 2.1 AA
To understand why overlays fail, we need to understand the legal measurements used by the Department of Justice (DOJ) and the courts. ADA enforcement for digital properties is centered on the Web Content Accessibility Guidelines (WCAG) 2.1 Level AA.
Unlike a visual ‘skin,’ WCAG 2.1 AA requires deep-seated structural integrity.
It requires that:
- Forms (for example, patient intake forms, patient history forms) are programmatically labeled so that screen-reading software can interpret them.
- Navigation can be handled entirely via keyboard for those with motor impairment.
- Semantic HTML is used so that assistive technology can identify headers, lists, and links.
Overlays operate as a JavaScript ‘band-aid’ that sits on top of your site. They do not actually fix the underlying source code. As a result, when a patient using a screen reader visits the site, their software interacts with the broken code before the overlay loads. Worse yet, the overlay often conflicts with the user’s existing assistive settings.
Imagine your physical office doesn’t have a wheelchair accessible entrance. You wouldn’t give it a second thought, you would have to bring in a contractor to install a wheelchair ramp. What if, instead of the expense of the ramp, you were offered a service for a nominal fee, someone will wait in your lobby, and when someone with accessibility issues arrives, this service has someone come outside and lift the person up the stairs.
That sounds absurd doesn’t it? That is what the overlay services are offering you.
The Case Law Reality Check
Many of the top overlay providers promise ‘legal protection’ to some degree. Here are three specific legal cases that demonstrate that courts are not impressed by these ‘solutions’:
- Murphy v. Eyebobs (2021)
In a legal case involving accessibility, a blind plaintiff demonstrated that the widget did not make modal dialogs and promotional pop-ups accessible to screen readers.
The court's refusal to dismiss the case sent a strong message: relying solely on an overlay is not a valid defense. Eyebobs ultimately settled, removed the overlay, and committed to a thorough manual audit and remediation of their accessibility issues.
- Quezada v. U.S. Wings (2021)
This case highlighted the technical gap between an overlay’s promises and a user’s reality.
The plaintiff, who is legally blind, encountered numerous barriers, including unlabeled buttons and broken links that the overlay failed to address.
The court denied the defendant's motion to dismiss, affirming that the presence of an accessibility tool does not "moot" a lawsuit if the underlying barriers—as defined by WCAG standards—still exist.
- Alixpartners v. ADA Site Compliance (2023)
The Alixpartners case underscored the risk of third-party reliance. This litigation involved complex disputes over whether automated tools could ever satisfy the "effective communication" requirements of the ADA.
The consensus from legal experts analyzing such cases is that a "set it and forget it" approach with an overlay is viewed by the courts as a failure of due diligence rather than a proactive attempt at compliance.
What could go wrong?
Cutting corners instead of just doing it correctly quickly becomes significantly more costly.
Why Should You be Concerned about your Medical Practice website?
For healthcare professionals, the stakes are higher than they are for typical retailers. Your digital tools handle Sensitive Personal Information (SPI) and critical care functions.
- The “Double Burden” of Privacy
Many overlay providers track user behavior and store cookies to ‘remember’ disability settings. For medical practices, this raises significant concerns regarding unauthorized collection of health-related information. For example, if an overlay identifies a user as having a ‘seizure disorder’ to adjust a website flashing, where is that information being stored?
- Patient Safety
If a patient cannot find your emergency contact information because a ‘skip navigation’ link is broken and an overlay cannot fix it, the issue shifts from a legal risk to a clinical one.
- Regulatory Deadlines
New HHS rulings and the 2024 updates to ADA Title II (for state and local government-funded entities, including many clinics and hospitals) explicitly point toward WCAG 2.1 AA as the required standard by 2026.
A Better Path Forward
If your practice currently uses an overlay, it is time to move beyond the widget. A defensible compliance strategy involves:
- A Professional Audit: Conduct a manual and automated audit of your site’s actual source code.
- Native Remediation: Fix accessibility issues at the code level. This ensures that the site is accessible by default, regardless of whether a third-party script loads.
- Ongoing Maintenance: Accessibility is a process, not a product. Regular checks should be part of your digital hygiene, much like your HIPAA compliance reviews.
The Bottom Line: An accessibility overlay is a cosmetic fix for a structural problem. In the eyes of the law, and more importantly, in the eyes of your patients, it is no substitute for a truly inclusive digital experience.
Is your current website strategy focused on genuine access, or are you relying on a "quick fix" that might leave your practice vulnerable?
Are you currently using an automated overlay on your practice's website, and have you ever conducted a manual accessibility audit to verify its effectiveness?
