What is preventive care?

Short answer

Preventive care is medicine aimed at the time before you feel sick: screenings (blood pressure, cholesterol, Pap tests, mammograms, colonoscopies), vaccines, and the checkups that tie them together.

The policy is generous: under the ACA, most plans must cover a defined preventive list - immunizations and many screenings - with no copay or deductible in-network, per HealthCare.gov (details vary; $0 is not guaranteed in every case). The catch: preventive is free while it stays preventive - a screening that turns diagnostic can be billed as diagnostic. The cheapest move in healthcare remains the boring one: stay current on the screening and vaccine lists for your age. Pymander is a free AI doctor, 24/7 by text, and can tell you which apply to you.

Common questions

What is preventive care?

Preventive care is medicine aimed at the time before you feel sick: the screenings that catch disease early (blood pressure checks, cholesterol panels, cancer screenings like Pap tests, mammograms, and colonoscopies), the vaccines that block it outright, and the checkups that tie it together. The economic argument is one-sided: catching high blood pressure at a free screening beats paying for the stroke; a vaccine costs less than the ICU. The policy argument is just as strong: under the Affordable Care Act, most insurance plans must cover a defined list of preventive services - immunizations and many screening tests - with no copay, coinsurance, or deductible when you use an in-network provider, per HealthCare.gov (with the caveat that coverage details vary and $0 is not guaranteed in every case). The catch to know: preventive is free only while it stays preventive - if a screening finds something and the visit turns diagnostic, the diagnostic part can be billed; and an annual-physical conversation about a knee problem is a diagnostic visit, not a preventive one. The cheapest move in healthcare is still the boring one: stay current on the screening list for your age and the vaccine list for your life.
