Got a call from this number that was legitimately from Group Health. They called to "offer" me an appointment, a follow up request from my doctor. I didn't call it back to see if it works both ways, but I just wanted to report that I got a call that was totally legit. This is Group Health.
I work for Group Health. All their phone numbers from the Tacoma area show up like this due to patient privacy, in other words if they are calling regarding a specific patient they are not going to allow a special phone number to show up. For example if they need to make a urology appt then the urology number won't show because it has to do with patient confidentiality. HIPPA. Just like all phone numbers from Tacoma General Hospital come through as 403-1000, but if you call it back it does go the operator but you have no clue who specifically they were calling.
