Amedisys: The $106 Million DOJ Settlement Over Therapy Minute Inflation at the Home Health Giant

Amedisys Inc., one of the largest home health agencies in the United States, agreed to pay $106 million to the Department of Justice to resolve False Claims Act allegations that the company had systematically directed therapists to inflate the therapy minutes documented in patient records for the purpose of pushing patients above the threshold minutes needed to qualify for higher Medicare reimbursement tiers — a upcoding scheme that generated millions in excess Medicare payments at the expense of accurate clinical documentation and, potentially, at the expense of patients receiving the appropriate amount of therapy for their actual clinical needs.DOCUMENTED

The Amedisys settlement was among the largest False Claims Act resolutions in the home health sector and reflected the DOJ and HHS-OIG's recognition that the Medicare home health prospective payment system's therapy threshold structure had created pervasive financial incentives for home health agencies to inflate therapy minutes — incentives that the agencies found had corrupted clinical documentation practices at Amedisys on a large scale.

How Home Health Reimbursement Created Perverse Incentives

The Medicare home health prospective payment system that was in place during the period covered by the Amedisys settlement paid home health agencies a fixed amount for each 60-day episode of care, with the episode payment amount determined by a case-mix classification that incorporated the patient's clinical characteristics — including the number of therapy visits and minutes documented during the episode. The system included discrete thresholds: episodes with documentation showing ten or more therapy visits received higher reimbursement than episodes with fewer visits, and similar thresholds existed at other visit counts. This structure created a non-linear reimbursement incentive — a home health agency that could push a patient's documented therapy just over a threshold received meaningfully higher payment for a very small difference in the documented clinical activity.REVIEWED

The DOJ's investigation, consistent with academic research published at the time, found that the distribution of documented therapy minutes in Medicare home health claims showed unusual clustering just above the reimbursement thresholds — patterns inconsistent with natural variation in patient clinical needs but consistent with systematic documentation inflation designed to capture higher payment tiers. The statistical evidence of threshold-gaming documented in academic research was consistent with the specific practices the DOJ's investigation found at Amedisys: instructions to therapists to ensure their documentation reached threshold levels, pressure to add therapy minutes to approach thresholds in patients whose clinical progress was assessed near the end of an episode, and evaluation of therapists and clinical staff partly on the basis of their success in keeping patients above payment thresholds.DOCUMENTED

The Clinical Documentation Corruption

The Amedisys scheme corrupted clinical documentation in a way that went beyond the financial fraud to potentially affect patient care. Clinical documentation in home health is the basis on which therapy is planned, delivered, and evaluated — when documentation inflates the minutes of therapy provided, the clinical record does not accurately reflect what therapy the patient actually received, making it difficult to assess the patient's response to treatment or to identify situations where the patient was not receiving adequate therapy. A therapist who documents ten minutes of therapy that was not actually provided, to push a patient over a reimbursement threshold, has created a false clinical record that serves the home health agency's financial interest at the expense of accurate documentation of the patient's care.REVIEWED

The pressure on therapists to inflate documentation placed them in a professionally and ethically difficult position: comply with management instruction to hit therapy thresholds and compromise clinical documentation integrity, or resist and face the professional and employment consequences of not meeting documented performance expectations. Many of the whistleblower complaints in the Amedisys case came from therapists who had experienced this pressure directly and who found the clinical documentation inflation inconsistent with their professional obligations — therapists who recognized that falsifying therapy minutes was both a federal false claims violation and a breach of their professional duty to maintain accurate patient records.

Asking a physical therapist to document therapy minutes that were not provided is not asking them to round up. It is asking them to falsify a clinical record — and the therapists who refused to do it were the ones who reported the scheme to the government.

CMS Response and Payment System Reform

The therapy threshold gaming documented at Amedisys and identified across the home health sector by researchers and CMS itself was a significant factor in the Centers for Medicare and Medicaid Services' decision to redesign the home health prospective payment system. The Patient-Driven Groupings Model, which replaced the therapy-threshold-based payment system in 2020, moved to a payment model based on clinical characteristics rather than on the volume of therapy minutes — specifically to eliminate the financial incentive to inflate therapy documentation that the prior system had created. The reform represented a recognition that the payment system design had been a significant contributor to the widespread documentation inflation problem, and that sustainable fraud prevention required changing the incentive structure rather than relying solely on enforcement against the fraudulent documentation it generated.DOCUMENTED

For the thousands of patients who received care from Amedisys during the period covered by the DOJ settlement, the therapy minute inflation may have had direct effects on their care — some patients may have received therapy at levels determined by threshold considerations rather than by clinical need, while others may have had documentation of therapy that was not actually delivered. The $106 million settlement cannot fully compensate for the clinical documentation integrity harm to those patients, but the payment system reform and the enforcement accountability represented by the settlement together address both the systemic incentive problem and the specific corporate conduct that exploited it.

Compliance in Home Health Documentation

The Amedisys case reinforces the principle that home health agency clinical documentation must accurately reflect the care provided — and that management instruction to inflate documentation to capture higher reimbursement tiers constitutes a direction to engage in fraud, regardless of how the instruction is framed. Home health agencies that experienced the pressure of the prior payment system's therapy thresholds without engaging in documentation inflation demonstrate that compliance was possible even under an incentive structure that encouraged fraud, and the therapists who reported Amedisys's practices to the government demonstrate that healthcare professionals have legal and ethical tools available when their employers instruct them to falsify clinical records. The combined effect of payment system reform and enforcement accountability has substantially improved the integrity of home health documentation — at a cost of $106 million to the company that chose to exploit the prior system's incentives rather than document therapy accurately.
