Field notes
The high-cost-care estimator uses an income category, monthly medical-cost total, and out-of-pocket payment to calculate a limit and estimated reimbursement. Its listed options include household aggregation, repeat-treatment rules, and an annual cap marked as a reference value. The companion tax tool shows the estimated deductions for two systems but explicitly leaves the choice to the user; reimbursement estimates can be transferred between the tools.
