What medical issues can a telehealth service genuinely resolve remotely — and when does a senior still need to go in person?

Telehealth physicians can diagnose and prescribe for conditions not requiring physical examination: urinary tract infections, respiratory infections, skin conditions reviewed by photo, and follow-up for chronic conditions. Physical examination cannot be replicated remotely, which limits scope for new or undifferentiated symptoms. The most practical use case is avoiding urgent care visits for conditions clearly within a GP's scope that arise outside office hours.
