Attention Humana Medicare Advantage Patients! As of 12/1/2016, we have confirmed that Humana has loaded all of the Thunderbird Internal Medicine (TIM) physicians into their system. If you have a Humana Medicare Advantage HMO plan and want to be seen by one of our PCP's, you must contact Humana at 1-800-457-4708 and have your PCP reassigned to a TIM physician. Be sure to ask the Humana representative the effective date of the change. If you have any questions, feel free to call us at (602) 938-6960, option 6.
