You're not feeling well. You have a fever, a sore throat, an unusual pain. What do you do? You seek medical attention, of course. Why? Because when you are sick, you go to the doctor. But are there reasons to go to the doctor when you're not sick?
When my husband was 55, he went to his primary care doctor and suggested that it was probably time he got a colonoscopy (an initial one is recommended at age 50 and his mother had colon cancer), maybe an EKG or treadmill test (his dad had a massive heart attack at age 52), and maybe a shingles or pneumonia vaccination. His doctor said, "Why are you asking for all of this? I don't get paid for ordering or providing these services." In other words, "I provide sick care, not wellness/preventive care." Not only was his statement true, but in most cases, commercial insurance does not pay for services that are intended to prevent, not treat, a certain condition; so if patients want these tests, they have to pay for them themselves.
Fast forward to 2012. Medicare expanded benefits to their fee-for-service beneficiaries to include an annual wellness visit. This is a visit focused on maintaining and improving health, making a plan for preventive and screening care, and keeping the clinic up to date on all the care a patient is receiving. An annual wellness visit includes a review of all the medications a patient is taking, the names of all other doctors they are seeing and the patient's medical/family history. Among other things, the doctor conducts a screening for depression, assesses the patient's ability to perform activities of daily living, his or her risk of falling and any hearing impairment.
