The federal government has issued a subpoena asking for documents from NuVasive, a company that makes spine devices, NuVasive revealed in a quarterly filing with the Securities and Exchange Commission. The subpoena came from the Department of Health and Human Services' Office of the Inspector General and is related to alleged "improper claims submitted to Medicare and Medicaid."

The bottom line: Receiving a subpoena from the OIG is always a huge red flag. NuVasive, which got hammered by investors for a poor second quarter, did not elaborate further on the subpoena and said it will "fully cooperate with the OIG's request."

Why it matters: Documents provided to Axios reveal a new layer of secrecy within the maze of American drug pricing — one in which firms that manage drug coverage for hundreds of employers, representing millions of workers, obscure the details of their work and make it difficult to figure out whether they're actually providing a good deal.

Congress' chip-funding pause raises alarms

Illustration: Aïda Amer/Axios

Despite bipartisan support in the Senate, a plea by the Commerce Secretary and growing desperation from industry officials, Congress still can't get a key bill that funds the U.S. chip business over the finish line.

Why it matters: With the global chip shortage continuing to crimp the economy, the semiconductor industry has ramped up pressure for funding of U.S.-based manufacturing facilities as one remedy.
