Caution: repeated calls from 1‑866‑428‑4776 often masquerade as United Healthcare reminders. Many recipients report automated messages that claim to be health‑plan check‑up alerts, yet United Healthcare consistently denies sending them. This pattern matches typical scam behavior—unverified callers request a callback and a confirmation code. Protect yourself by never returning the call to the number left on the voicemail; instead use the official phone number on your insurance card or the provider’s website. If the call insists on personal details, hang up and report the number to the FCC and your insurer. Keeping a record of the call can also help authorities track abusive robocalls.
There have been two calls from this number, one recently and one a few weeks ago, but no messages were left either time.
