The address at home is only part of the story
A few nights away can mean another state’s rules, even with the same doctor.
Imagine keeping an online appointment while you're staying with relatives. The record still has your address back home. The doctor is familiar. The detail that needs updating is where you're sitting today.
HHS says professionals must meet the rules where they are and have permission to practice where you are. That's our first question, rather than the final answer about your care. Permission for a visit doesn't automatically mean permission for a prescription.
Name the place where care happens

We keep three places separate: home, tonight's stop and the place where the appointment happens. During an evacuation, those might be three different places. Naming the city and state is clearer than saying you're somewhere along the Gulf.
The state chapters begin there too. They explain the rules for a place; they don't list where a particular doctor can work. We use the coastline to organize the reading, not to draw a service area.
Similar names, different permissions
HHS describes several ways states handle cross-state practice, including full licenses, temporary practice provisions and telehealth registration. Each has conditions. A weekend stay doesn't tell us which route is available or whether a doctor has completed it.
For example, Florida’s out-of-state telehealth registration doesn't allow in-person care there. Louisiana describes a telemedicine permit for physicians without an active Louisiana medical license. Those aren't interchangeable permissions. One state's paperwork doesn't answer another state's question.
What does that change for the plan?
We'd work through the questions in order: where the visit will happen, whether the doctor can practice there, then what the care and prescribing rules require. We'd include follow-up now, so the plan reaches beyond the next appointment.
We wouldn't assume a storm creates an exception. HHS describes some temporary practice routes, but that doesn't tell us whether a particular disaster order or exemption applies. That needs a current answer for the actual situation.
Our storm journey follows a hypothetical move from Louisiana to Mississippi and Alabama. It gives those questions a place in the trip. The controlled-prescription page explains the next layer, including why federal permission still leaves state rules to check.
