Everything about my visit to this location for the vaccine was excellent. Everything and I was extremely impressed with their sanitizing as mentioned in my prior review. My only disappointment was with their main office billing and I cut the ties when I opted out of them trying to put me in MediCal when I have other insurance that would pay 100% for tests and vaccines if the correct CPT code were used. I would strongly recommend others to use this site if they have MediCal. Two perfect visits.Yesterday I had two spam calls just a minute or two apart and then I got a third call and I really cussed when I answered saying to never call my number again. I had no idea it was from this group as it said unknown caller. When I saw Huntington Park I called back and heard it was AltaMed and the wait was 199 minutes. Of course I hung up. I had already deleted all their numbers from my Contacts.I have no idea why they were calling but it was probably to tell me I was eligible for the Pfizer booster. I had already decided I was never returning and I had messaged them that I was not returning to any AltaMed and I had decided I would get the booster from a pharmacy. I was more disappointed that both vaccines from February and March still have not been billed to my insurance TO DATE. I just do not have time for these kind of problems. I pay hefty insurance premiums and I just expect correct billing. The billing for the test at another AltaMed site was outrageously wrong not showing the COVID test but as a new patient and paid a ridiculous amount. That red flag sent me away. If the billing had not been such a fiasco requiring me to make too many calls I probably would have made this my home office because of the friendliness and protective measures to make sure patients were not exposed to COVID19. It was nice to sit in a lobby and not be made to feel like a fly in a fruit bowl as other places made me feel since I was not of the same background of the majority there..Anyone willing to make a commute through an industrial area should know this facility has been superior to any I visited in the last 5 years.
