AdaptHealth Corp. (AHCO), a seller of home medical equipment (HME), medical supplies, and home and related services, belatedly disclosed a second federal fraud probe related to potentially illegal billings and reimbursements over the course of nearly a decade.

No mention was made of the matter in the company’s earnings release.

AdaptHealth’s latest quarterly filing revealed the new investigation centers on its CPAP humidifiers and goes back eight years:

“On July 29, 2024, the U.S. Attorney’s Office for the District of South Carolina issued a civil investigative demand to the Company pursuant to the False Claims Act, 31 U.S.C. § 3733 ("FCA") surrounding whether the Company submitted false claims in violation of the FCA related to its billing of, and reimbursements from, federal health care programs for humidifiers that are integrated with CPAP devices and provided to patients from January 1, 2017 to the present.”

In August, AdpatHealth revealed it had received a CID from the U.S. Attorney’s Office in the Southern District of New York probing whether the company violated the FCA in its billing of, and reimbursements from, federal health care programs for ventilators provided to patients.

This probe goes back ten years.

Since receiving the second CID, AdaptHealth has filed nine current or quarterly reports with the SEC without disclosing the new fraud probe.

Since July, AdaptHealth has ousted its CEO, reassigned its Chief Operating Officer, and awarded its CTO a new contract.

Notably, with probes underway in New York and South Carolina, AdaptHealth serves patients in all fifty states and has 680 locations in 47 states.
