USPSTF guidelines, in plain language
The US Preventive Services Task Force (USPSTF) decides which preventive tests, screenings, and counseling are worth doing for the average American adult. Their official documents are dense. This page translates the grading system into things you can actually ask for at a walk-in clinic.
What is the USPSTF?
The USPSTF is an independent panel of primary-care and prevention experts convened by the federal Agency for Healthcare Research and Quality (AHRQ). They review the evidence for preventive services and publish a letter grade (A, B, C, D, or I) for each one. Under the Affordable Care Act, most private insurance plans, Medicaid expansion plans, and Medicare are required to cover services graded A or B with no copay.
Canadian patients: the equivalent body north of the border is the Canadian Task Force on Preventive Health Care. Recommendations often overlap with the USPSTF but sometimes differ (breast, prostate, and lung cancer screening are the most common divergences). Our checklist tool uses whichever set matches the country you select in the header.
The grades, explained
What it means: The USPSTF is confident the benefit is substantial and clearly outweighs the harms for people in the eligible group.
What to do at a walk-in visit: Insurance must cover it with no copay if you're in the eligible age/risk group. Ask for it by name; a walk-in clinician can usually order it the same day.
What it means: Benefit is moderate to substantial and outweighs the harms. Slightly less certain than A, but still a clear yes.
What to do at a walk-in visit: Also covered with no copay. Same script as an A: ask for it by name and expect it to be ordered.
What it means: Benefit is small on average. Some people still benefit more than others based on risk factors, values, or family history.
What to do at a walk-in visit: Not automatically free — but if you have a reason (family history, symptoms, personal preference), say so. Bring the reason to the visit; a walk-in clinician can order it if the rationale is documented.
What it means: Evidence shows no benefit or that harms outweigh benefits for the average patient.
What to do at a walk-in visit: You probably don't need this test even if you saw it on a TikTok checklist. Ask the clinician why they'd order it before agreeing.
What it means: The USPSTF couldn't find enough good evidence to say yes or no. Not the same as 'no' — just 'we don't know.'
What to do at a walk-in visit: Fair game to discuss. Ask what the current thinking is and what the clinician would recommend for someone with your profile.
How to use this at a walk-in visit
- Build your personalized list with the checkup tool. It already reflects A- and B-graded USPSTF (and Canadian Task Force) recommendations for your age, anatomy, and risk factors.
- Print or save your prep sheet and bring it in. Walk-in clinicians appreciate a specific ask ("USPSTF grade B — colorectal screening, age 45+") more than a vague one ("do I need any tests?").
- If a clinician pushes back on an A/B service, it's reasonable to say: "This is a USPSTF grade A recommendation and should be covered — can we document it?"
- For C-graded services (e.g. some cancer screenings under age 50), bring your family history or risk factors. That's often what tips an individual decision toward doing the test.
A few high-impact A and B recommendations
- Colorectal cancer screening (A, ages 45–75): stool test, sigmoidoscopy, or colonoscopy.
- Blood pressure screening (A, adults 18+): usually done at every visit.
- Hepatitis C screening (B, adults 18–79): a one-time blood test for most adults.
- HIV screening (A, ages 15–65): one-time for most, more often if risk factors apply.
- Cervical cancer screening (A, ages 21–65 with a cervix): Pap and/or HPV testing on a schedule.
- Statin use for cardiovascular disease prevention (B, ages 40–75 with risk factors): discuss with a clinician if you have high blood pressure, diabetes, or high cholesterol.
- Depression screening (B, adults 18+): a short questionnaire; ask if it wasn't offered.

Build my checklistThis is not medical advice. Clinic Compass is an educational tool to help you prepare for a walk-in visit. It does not create a doctor–patient relationship, does not diagnose or treat any condition, and is not a substitute for the judgement of a licensed healthcare professional who knows your history. Never delay, avoid, or change medical care because of something you read here. In an emergency, call 911 or your local emergency number.
