Physical therapy denial lawsuits are legal actions filed by physical therapists, patient advocacy groups, and industry associations against the federal government and insurance companies over unfair restrictions and denials of coverage for physical therapy services. These lawsuits challenge two main issues: Medicare’s blanket ban on private-pay arrangements for physical therapists (which other licensed providers can access) and insurance companies’ systematic claim denials that prevent patients from receiving and paying for necessary treatment. For example, a patient with post-surgical rehabilitation needs might have their physical therapy claim denied for “insufficient medical necessity” by an insurer, then discover that the same treatment would be approved for a similar patient with a different insurance plan—revealing the arbitrary nature of these denials.
The scope of physical therapy denials has become a major legal issue because the problem affects millions of patients and thousands of providers. Insurance companies deny an average of 6-13% of physical therapy claims nationwide, with rates climbing to 15-24% at independent practices. Meanwhile, Medicare’s restriction on physical therapists—who cannot opt out and contract privately like doctors, nurse practitioners, clinical psychologists, and social workers—has sparked a federal constitutional challenge. These lawsuits represent both a practical problem for patients struggling to access care and a fundamental question about fairness in healthcare regulation and insurance practices.

What Is the Medicare Private-Pay Ban Lawsuit?
In August 2025, Dr. Sean Wells and the United Physical therapy Association (UPTA) filed a federal lawsuit challenging Medicare’s prohibition on private-pay arrangements for physical therapists. The case, Dr. Sean Wells, et al. v. Kennedy, et al., argues that Medicare’s blanket ban violates the Fifth Amendment’s Equal Protection and Due Process Clauses and exceeds Congressional authority.
The core issue is a clear disparity: Medicare allows most licensed healthcare providers—including doctors, nurse practitioners, clinical psychologists, and social workers—to opt out of Medicare entirely and contract privately with patients. Physical therapists, however, face an absolute ban on this arrangement, with severe penalties for non-compliance including fines and professional banishment from Medicare reimbursement. This lawsuit directly challenges the fairness of restricting one licensed profession while allowing others the same freedom. Physical therapists argue that the ban effectively locks them into Medicare’s lower reimbursement rates with no legal alternative, while physicians in the same settings can simply opt out and charge private rates. The plaintiffs claim that singling out physical therapists violates equal protection because it treats them differently from other licensed healthcare providers in functionally equivalent positions. The case raises constitutional questions about whether Congress has the authority to impose such restrictions and whether those restrictions are rationally related to legitimate government interests. If successful, this lawsuit could fundamentally change how Medicare reimbursement works for physical therapists across the country.
How Insurance Companies Deny Physical Therapy Claims
insurance claim denials have become a systemic issue in physical therapy coverage. According to 2024 data, insurance plans deny 19% of in-network physical therapy claims and 37% of out-of-network claims, with independent practices experiencing denial rates as high as 18-24% for specific procedure codes like CPT 97110 (therapeutic exercises). These denials are not random—they follow predictable patterns that patients and providers can often identify and challenge. The two most common reasons for denial are medical necessity issues (approximately 30% of denials) and eligibility or registration problems (26.6% of denials according to Change Healthcare data). A patient might be denied because the insurance company claims insufficient documentation that the therapy was medically necessary, or because paperwork wasn’t properly submitted or the patient’s coverage wasn’t verified before treatment began.
What makes this system particularly frustrating is that up to 50% of denied claims can be successfully appealed—yet less than 1% of patients ever actually challenge a denial, and only 35% of denied claims are ever resubmitted. This means enormous amounts of legitimate reimbursement money disappears simply because patients don’t know they have the right to appeal. When patients do appeal properly documented claims, the success rate climbs dramatically: CPT 97110 claims have a 67-72% appeal success rate when properly documented. The timing of resubmission matters critically—claims submitted within 7 days of initial denial have a 67% chance of payment, while those submitted after 7 days drop to only 40%. Many patients and providers don’t realize this deadline exists, causing them to lose payment opportunities by submitting appeals too slowly.
The Antitrust Price-Fixing Lawsuit Against Insurance Giants
Beyond individual claim denials, the American Physical Therapy Association (APTA) and APTA Private Practice filed a major antitrust lawsuit in the Northern District Court of Illinois in 2024 against a coalition of major insurance companies and intermediaries. The defendants include MultiPlan/Claritev, UnitedHealth, Elevance (Anthem), Humana, Aetna, Cigna, and various Blue Shield entities. The lawsuit alleges that these companies conspired to systematically underpay physical therapists for out-of-network services—a practice dating back to at least 2015. Rather than simply denying individual claims, the allegation is that insurers worked together to suppress reimbursement rates across the entire industry, creating a coordinated scheme that harms both physical therapists and patients seeking out-of-network care.
This price-fixing allegation reveals a different kind of denial problem: not claims denied for insufficient documentation or medical necessity, but rather rates set so artificially low that many physical therapists cannot afford to contract with insurers at all. The lawsuit seeks to end the anticompetitive scheme and recover financial damages for the systematically underpaid services. If proven, this case could demonstrate that insurance denials and reimbursement rates are not just individual company decisions but coordinated industry practices designed to limit what physical therapists can earn. For patients, this means they may have been charged out-of-network rates that were artificially depressed below what fair market rates would be, and physical therapists may have been forced to deny services or leave the profession entirely due to unsustainable reimbursement.
How to Appeal a Denied Physical Therapy Claim
When your physical therapy claim is denied, you have a documented right to appeal, and statistics show that proper appeals succeed 50% of the time or higher. The first step is to understand why your claim was denied—the explanation should be clearly stated on your denial notice. If the reason is medical necessity, work with your physical therapist to gather additional documentation supporting the clinical need for your treatment. This might include your initial evaluation, progress notes showing improvement markers, physician referral documentation, or imaging results. If the denial reason is eligibility or registration issues, verify your insurance coverage was active on the date of service and that your provider was properly in-network or that you received necessary pre-authorization.
For CPT 97110 claims specifically, which have high appeal success rates (67-72%), ensure your treatment notes clearly document the therapeutic exercises performed and their medical necessity. The timing of your appeal is critical: submit your appeal within 7 days of the denial notice to maximize your payment chances (67% success rate versus 40% if submitted later). Contact your insurance company’s appeals department directly, provide your member ID and claim number, and submit your supporting documentation in writing. If your insurance company denies the appeal, most states allow a second level of appeal, and some policies include independent external review. Many patients benefit from having their physical therapist’s office staff help with the appeal process, as they often have experience navigating each insurance company’s specific requirements. The tradeoff is that while appeals can recover 40-60% of denied claim amounts, they also require time and effort—but given the high success rates and the amount of money at stake, the effort typically pays off financially.
Common Physical Therapy Denial Reasons and Prevention Strategies
The most frequent reasons for physical therapy claim denials fall into clear categories, and understanding them helps you prevent denials before they happen. Medical necessity denials (30% of all denials) occur when insurers believe your treatment wasn’t clinically justified. This happens when initial evaluation documentation doesn’t clearly establish that physical therapy was appropriate, when there are gaps in progress notes showing improvement, or when treatment continues beyond what the insurance company believes is necessary. The second major category is eligibility and registration issues (26.6% of denials), which includes situations where your coverage wasn’t active on the date of service, your provider wasn’t properly contracted with your insurance, or required pre-authorization wasn’t obtained before treatment began. A third category, less frequently mentioned but important, involves billing code errors—submitting the wrong CPT code or unbundling codes improperly can trigger denials.
To prevent denials, always verify your insurance coverage before your first appointment and confirm that your physical therapy provider is in-network. Ask your provider if they need pre-authorization from your insurance before beginning treatment—some insurance plans require this, and starting without it almost guarantees a denial. Request a copy of your initial evaluation and progress notes, as these become critical if you need to appeal. Work with your physical therapist to ensure their documentation clearly connects your diagnosis and symptoms to the specific treatment being provided. For ongoing therapy, ask your therapist to monitor your progress regularly and discuss with you if it appears you’ve plateaued, since continuing treatment with no improvement is a common denial reason. The limitation here is that while these prevention strategies significantly reduce denial risk, some denials still occur due to insurance company errors or overly restrictive policies that aren’t your fault—which is why knowing how to appeal is equally important.
Your Rights as a Physical Therapy Patient
You have specific legal rights when physical therapy claims are denied, including the right to appeal and the right to receive a written explanation for any denial. Your insurance company must provide this explanation in clear language within a reasonable timeframe, typically 30 days for standard claims. You also have the right to request an external review of an appeal if you believe your insurance company’s decision was unfair, and many states legally require this option. Additionally, if you’re a Medicare beneficiary, you have the right to appeal a Medicare denial through a multi-level appeals process that eventually includes an independent Administrative Law Judge review if needed.
Another important right is your ability to pay out-of-pocket for physical therapy without losing your insurance coverage. While this sounds obvious, some patients mistakenly believe that if they can’t get insurance approval, they can’t proceed with treatment at all. In reality, you can always choose to pay privately for physical therapy, though this requires understanding the costs upfront. If you later prove that the denial was improper through a successful appeal, you may be able to request reimbursement for out-of-pocket payments you made. Document everything if you proceed this way: keep your receipts, invoices, and treatment records carefully organized in case you need to pursue reimbursement later.
The Future of Physical Therapy Coverage and Legal Changes
The lawsuits filed in 2024-2025 suggest that physical therapy coverage and reimbursement are entering a period of significant legal and regulatory change. The Medicare private-pay ban lawsuit, if successful, could create a new option for physical therapists to contract privately with Medicare patients, potentially increasing access to care while reducing insurance-related denials for those patients. The antitrust price-fixing lawsuit could reset reimbursement rates industry-wide if proven, addressing one of the root causes of claim denials and provider shortages. Even if these specific cases don’t succeed, they’re signaling to courts, regulators, and lawmakers that the current physical therapy coverage system has serious fairness and access problems.
Looking forward, expect increased scrutiny of insurance claim denials across all healthcare services, not just physical therapy. The fact that less than 1% of patients appeal denials, combined with 50% appeal success rates, has attracted attention from consumer advocates and regulators who see a system where massive amounts of legitimate payments simply vanish. Regulatory changes, new appeals requirements, or insurance industry reforms could make denials less frequent or easier to challenge. For patients navigating the system now, this means the landscape may improve, but also that being proactive about understanding your coverage and appealing denials is more important than ever.
Conclusion
Physical therapy denial lawsuits represent both immediate practical issues—millions of denied claims and unfair reimbursement restrictions—and broader questions about fairness in healthcare regulation and insurance practices. The Medicare private-pay ban lawsuit challenges whether the government can prohibit physical therapists from accessing options available to other licensed providers, while the antitrust lawsuit alleges that major insurers have conspired to artificially suppress reimbursement rates. For patients dealing with denied claims right now, knowing that 50% of denials can be successfully appealed, and that appeals should be submitted within 7 days, provides a concrete path to recovering benefits.
If you’ve had a physical therapy claim denied, don’t assume the denial is final. Document the denial reason, gather supporting medical evidence with your physical therapist, and submit an appeal within a week. If you’re interested in the broader lawsuits challenging the fairness of physical therapy coverage—whether the Medicare ban or the insurance price-fixing allegations—check the Pacific Legal Institute and United Physical Therapy Association websites for updates. The outcome of these cases may reshape how physical therapy is covered and paid for across the country, making this an important moment to understand your rights and options.
