What happens during an annual health screening
An annual health screening is a routine visit to your doctor where they check your overall health, look for early signs of disease, and update your medical records. The visit typically includes measuring your blood pressure and weight, listening to your heart and lungs, and asking about any new symptoms or changes since your last visit. Your doctor may also order blood tests or other screenings based on your age, medical history, and risk factors.
The screening is not a diagnosis — it is a way to catch problems before you feel sick. For example, high blood pressure often has no symptoms, but finding it early lets you manage it before it causes a heart attack or stroke. Similarly, screening blood tests can detect high cholesterol, diabetes, or anemia when they are still straightforward to treat.
How long the visit takes depends on what your doctor finds and what tests are ordered. A straightforward screening might take 30 minutes; if your doctor finds something that needs follow-up, the visit may be longer or you may need to schedule additional appointments.
Key Takeaways

- If you do not have insurance, community health centers and free clinics often offer screening services on a sliding fee scale.
What screenings are recommended at different ages
The screenings your doctor recommends depend on your age, sex, and personal health history. There is no single list that applies to everyone, but major health organizations like the U.S. Preventive Services Task Force publish guidelines that doctors use.
For adults in their 50s and 60s, common screenings include blood pressure checks, cholesterol tests, diabetes screening, and colorectal cancer screening (usually starting at age 45 or 50). Women may also have mammograms for breast cancer and bone density scans. Men may discuss prostate cancer screening with their doctor, though the decision to screen is more individual than it once was.
For adults 65 and older, the list often expands to include screening for abdominal aortic aneurysm (a one-time ultrasound for men who have ever smoked), cognitive decline, and depression. Your doctor may also check your vision and hearing, review your medications for ones that are no longer needed, and assess your risk of falling.
If you have a chronic condition like diabetes or heart disease, your screening may include more frequent blood tests or imaging to monitor that condition. Your doctor will tell you which screenings make sense for your situation.
How to prepare for your annual screening
Before your appointment, gather a list of all medications and supplements you take, including the dose and how often you take them. Bring your insurance card and photo ID. If you have had recent test results from another doctor, bring those too — they help your doctor see trends over time.
Write down any symptoms or changes you have noticed since your last visit, even if they seem minor. This might be trouble sleeping, new joint pain, changes in appetite, or mood changes. Also note any questions you want to ask.
For some screenings, your doctor may ask you to fast (not eat or drink anything except water) for 8 to 12 hours before the visit. This is usually for blood tests that measure cholesterol or blood sugar. Your doctor's office will tell you if fasting is needed when you schedule the appointment.
Wear loose, comfortable clothing so your doctor can easily check your blood pressure and listen to your heart and lungs. If you track your blood pressure or weight at home, bring those records with you.
Understanding your screening results
Your doctor should explain the results of your screening before you leave the office or call you with results within a few days. If a test is normal, your doctor may straightforward say so and move on. If a result is abnormal, your doctor will explain what it means, whether it needs treatment, and what the next steps are.
An abnormal result does not always mean you have a serious problem. For example, slightly high cholesterol may be managed with diet changes before medication is considered. A small spot on a lung X-ray may need a follow-up scan in a few months to see if it changes. Your doctor will tell you whether you need when ready action, follow-up testing, or just monitoring.
Ask your doctor to explain results in plain language. If you do not understand something, say so. You can also ask for a written summary of your results to take home and review later.
If your doctor recommends a new medication or treatment, ask why, what the benefits and side effects are, and whether there are other options. You have the right to ask questions and take time to think before starting something new.
What Medicare and insurance cover
Medicare covers one annual wellness visit per year at no cost if you have been enrolled in Medicare Part B for at least 12 months. This visit includes a review of your health history, vital signs, and a personalized prevention plan. It does not include a physical exam in the traditional sense, but your doctor may do a basic check.
If you need additional screenings — such as blood tests, mammograms, or colonoscopies — Medicare covers many of these at no cost if they are deemed preventive. However, if your doctor finds something abnormal and does additional testing to diagnose a problem, that may have a copay or coinsurance.
Private insurance plans vary widely. Some cover annual screenings with no copay; others require a copay. Check your plan's summary of benefits or call your insurance company to find out what is covered before your visit. If you are unsure whether a screening is preventive or diagnostic, ask your doctor's office.
If you do not have insurance, many community health centers and free clinics offer screening services on a sliding fee scale based on your income. You can find a center near you through the Health Resources and Services Administration website or by calling 211.
When to schedule screenings outside your annual visit
Some screenings are not part of the annual wellness visit and may need to be scheduled separately. For example, a colonoscopy for colorectal cancer screening usually takes place at a hospital or outpatient center, not during an office visit. A mammogram is done at an imaging center. Your doctor will refer you to the right place and may schedule it for you.
If you develop new symptoms between annual visits — such as chest pain, shortness of breath, or a lump — do not wait for your next screening. Call your doctor right away or go to an urgent care clinic. These symptoms need prompt evaluation, not a routine screening.
If you have a chronic condition that requires frequent monitoring, your doctor may schedule you for visits or tests more often than once a year. For example, if you have diabetes, you may see your doctor every three months and have blood tests done more frequently.
Common concerns about annual screenings
Some people worry that screening will find something wrong and lead to unnecessary treatment. This is a real concern called overdiagnosis. For example, screening may find a slow-growing cancer that would never have caused harm. However, most screening tests are designed to find conditions that, if caught early, can be treated more effectively. Talk with your doctor about the benefits and risks of any screening before you have it done.
Others worry about the cost. If you have insurance, most preventive screenings are covered at no cost. If you do not, ask your doctor about lower-cost options or community health centers. Some employers and community organizations also offer free health fairs with basic screenings.
Some people feel anxious about the visit itself — worry about what the doctor might find, or discomfort with certain exams. It is normal to feel nervous. Tell your doctor if you are anxious; they can explain what will happen and may be able to adjust the exam to make you more comfortable.
Frequently Asked Questions
Do I need an annual screening if I feel fine?
Yes. Many serious conditions like high blood pressure, high cholesterol, and early-stage cancer have no symptoms. Screening can find these problems before you feel sick, when they are easier to treat. Even if you feel well, an annual visit lets your doctor update your records and catch changes over time.
What if my screening finds something abnormal?
An abnormal result does not always mean you have a serious disease. Your doctor will explain what the result means and what happens next. This might be a follow-up test, a lifestyle change, medication, or just monitoring. Ask your doctor to explain in plain language and to tell you what your options are.
Can I refuse a screening my doctor recommends?
Yes. You have the right to decline any test or screening. However, ask your doctor why they recommend it and what the risks are of not having it. Sometimes the decision to screen is a personal choice based on your values and preferences, and your doctor can help you weigh the pros and cons.
How often should I have blood work done?
This depends on your age, health, and risk factors. For most adults without chronic conditions, basic blood work (cholesterol and blood sugar) is recommended every few years. If you have diabetes, heart disease, or take certain medications, your doctor may order blood tests more frequently. Ask your doctor what schedule makes sense for you.
What should I do if I cannot afford the screening?
If you have Medicare, your annual wellness visit is covered at no cost. If you have private insurance, check what is covered before your visit. If you are uninsured, call 211 or visit 211.org to find a community health center near you that offers screenings on a sliding fee scale based on income.
