SDCL § 58-18A-71: Plan covering person as active employee.

The plan that covers a person as an active employee that is, an employee who is neither laid off nor retired or as a dependent of an active employee is the primary plan. The plan covering that same person as a retired or laid-off employee or as a dependent of a retired or laid-off employee is the secondary plan.

If the other plan does not have the provisions of this section, and as a result, the plans do not agree on the order of benefits, the provisions of this section do not apply.

This section does not apply if the provisions in § 58-18A-69 can determine the order of benefits.
