Do I need a referral to see an internal medicine doctor in Wisconsin?
It depends on your insurance plan, not the state. HMO plans usually need a referral from your primary care doctor; many PPO plans do not. Check with your plan before booking.
What should I bring to my first internal medicine doctor appointment?
A list of everything you take, including supplements, with how often; Your insurance card and photo ID; Recent lab results or imaging reports, if another clinician ordered them; Notes on any symptom: when it started, how often, how strong.
What is the difference between internal medicine and family medicine?
Internists care for adults only and train deeply in adult conditions. Family medicine doctors care for all ages, from children to older adults. Both can be your primary care doctor.
How often should I see an internist?
Many adults have a yearly check-up, and more often when a condition is being managed. Your doctor will suggest a schedule that fits your health.
