Annual Wellness Visit

Newly eligible Medicare beneficiaries are entitled to an initial wellness visit. At this time, we will:

  • Give you a health-risk assessment, which may include a questionnaire that you complete (with or without the help of your doctor) before or during the visit that looks at your health status, injury risks, risky behaviors and urgent health needs.
  • Take your medical and family history.
  • Make a list of your current health care providers, suppliers of durable medical equipment and medications. Medications include prescription medications, as well as vitamins and supplements that you may take.
  • Create a written 5-10 year screening schedule. This schedule depends on your individual health status, screening history and the age-appropriate, Medicare-covered, preventive services for which you are eligible.
  • Identify risk factors and current medical and mental health conditions along with related current or recommended treatments.
  • Check your height, weight, blood pressure and body mass index.
  • Screen for cognitive impairment, including diseases such as Alzheimer’s or other forms of dementia. Medicare does not require that physicians use a test to screen patients. Doctors are asked to rely on their observation of the patient or on reports by the patient and others.
  • Review risk factors for depression.
  • Review your functional ability and level of safety, including screening for hearing impairments and your risk of falling.
  • Assess your ability to perform activities of daily living such as bathing and dressing, and also your level of safety in your home.
  • Give health advice and referrals to health education or preventive counseling services or programs aimed at reducing identified risk factors and promoting wellness. These include weight loss, physical activity, smoking cessation, fall prevention and nutrition. 

Annual Wellness Visits after your first visit may be slightly different. As part of subsequent wellness visits, your doctor will:

  • Update the health-risk assessment you completed.
  • Update your medical and family history.
  • Check your height, weight, blood pressure, heart rate and body mass index.
  • Update your list of current medical providers and suppliers.
  • Screen for cognitive issues.
  • Update your written screening schedule from previous wellness visits.
  • Update your list of risk factors and conditions and the care you are receiving or that is recommended.

Annual Physical Exam

As part of the Affordable Care Act, most commercial insurance plans are required to cover an annual physical exam at no additional charge. During this exam, we will:

  • Update your health history. A doctor may ask to be updated on new developments, including job and relationships, as well as medications or supplements.
  • Check your vital sign, including blood pressure, height, weight, heart rate, respiratory rate and body mass index.
  • Conduct a visual exam. Your doctor will review your appearance for signs of any potential conditions.
  • Conduct a thorough physical exam, including checking the head and neck, abdominal area, hair, nails and limbs. The doctor will also listen to the heart and lungs.
  • Order laboratory tests. To complete the physical, the doctor may draw blood in order to run several laboratory tests. These can include a complete blood count and chemistry panel. This helps detect irregularities in the blood that might indicate a larger problem. The doctor may request a lipid panel, or cholesterol test, if a patient has an increased risk of heart attack, heart disease or stroke.
  • Screening tests might also be requested. These differ for women and men.
    • Women:
      • Mammogram: a mammogram is needed every two years between the ages of 50 and 74. A patient can request more or less frequent testing based on personal and family history of breast cancer.
      • Osteoporosis screening: bone density scans should begin around age 65.
    • Men:
      • Prostate cancer screening: Men may need prostate-specific antigen tests or digital rectal examinations. Breast exam: at each physical, a breast exam can be used to check for abnormal lumps or signs of breast cancer.
      • Testicular exam: A doctor may wish to check each testicle for signs of a problem, including lumps, changes in size, and tenderness.
    • Both Men and Women:
      • Colorectal cancer test: Begin tests for this cancer at age 50.
      • Depression: Many patients aren’t aware of their symptoms of depression because they are easily attributed to other things. However, a depression screening at each yearly check-up can check to see if symptoms are a result of depression.
      • Diabetes: People with a family history or risk factors for diabetes, such as high blood pressure and high cholesterol, should be screened for diabetes. Doctors may use the fasting blood sugar or the HbA1c test.
      • Sexually transmitted infections, or STI, screening: Based on personal sexual history, regular STI screenings during each annual physical exam may be suggested.
