Health care spending account (HSA) support. Under the U.S. tax code, an HSA is a tax-exempt account established exclusively for the purpose of paying qualified medical expenses. A requirement for an HSA is for the account beneficary to be covered by a high-deductible health plan — a plan type supported by the USTierCoverage component of HR-XML’s enrollment schema. See the revised Enrollment documentation for details, but the HSA support involved relatively minor changes to the USTierCoverage component. Several changes also were made to the USSpendingAccountCoverage component to better handle other types of spending account enrollments (healthcare reimbursement accounts, flexible spending accounts (FSAs), dependent care spending accounts, etc.).
