For persons with at least one private surgical insurance plan, PHISOBOTH reports whether the plan was obtained through some other group, rather than through an employer, union, or not through any group.

The definition, order, and wording of private health insurance changed over time to reflect changes in the availability of different types of coverage and issues of interest. Users are strongly encouraged to review the user notes Insurance Data Collection and Private Insurance Definitions.
