Who pays for a device recall

The manufacturer funds the remedy. The practical question is usually which link in the chain executes it.

  • If a clinic fitted or supplied the device, start there — they hold the serial-number records the manufacturer needs.
  • Ask for written confirmation that the remedy was applied to your serial number. That is what an insurer or a future clinician will want to see.
  • If you bought it yourself online or from a pharmacy, go to the manufacturer’s recall page rather than the retailer; device claims are handled centrally.
  • Where the remedy is a software update, there is nothing to claim, but do confirm the version changed afterwards.
