How 'Procedures to call insurance companies and verify coverage' prevents store shutdown? In my worldview insurance is 'sometimes we pay if ensured event occurs'. Lack or presence of the insurance changes nothing about the attack.
The post above you is talking about having manual communication with the provincial and federal medical insurance (Canada has national insurance) to confirm customers have the appropriate insurance ready so they can dispense pills, medication, and medical equipment, which is life critical equipment and supplies for many of their customers, without access to computers (which is doable if they had the procedures ready)
It’s to do with business continuity of the pharmacy’s work, nothing to do with breach.
It might be different for Canada though, so this continuity step could be omitted.
