Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

PlanVoyager compares ACA Marketplace health plans (HealthCare.gov) for 2026 coverage. Typical flow: search_plans with the person's ZIP, ages and yearly household income -> get_plan for details on the ones they like -> search_drugs / search_doctors then check_coverage to see whether their medications and doctors are covered. Plans are ranked by what a year would really cost: 12 months of premiums after the tax credit plus expected out-of-pocket care (from each plan's official coverage examples). Ask how much care they expect and whether a baby or surgery is planned; it changes the ranking a lot. States that run their own marketplace (e.g. CA, NY, NJ, PA, IL, GA, VA, CO, WA) are not covered; search_plans says so and links to the state's exchange. Numbers are estimates from CMS public data. Share each plan's url, and remind people to confirm prices and enroll at HealthCare.gov or with a licensed broker. Never give medical advice.
