Hyperbaric oxygen therapy (HBO therapy) involves giving a patient high concentrations of oxygen within a pressurized chamber in which the patient intermittently breathes in 100-percent oxygen. A prior Office of Inspector General review identified issues with Medicare payments for HBO therapy. More recently, a review by a Centers for Medicare & Medicaid Services (CMS) contractor found that claims for HBO therapy services were denied because of a lack of medical documentation. In 2015, CMS began a prior authorization demonstration program for non-emergent HBO therapy to test its effectiveness.

Payments made to providers for specimen validity tests did not comply with Medicare billing requirements. Specifically, Medicare improperly paid 4,480 clinical laboratories and physician offices a total of $66.3 million for specimen validity tests billed in combination with urine drug tests.
