Location, Directions, and Parking

Getting There from Different Parts of Atlanta

From Downtown / Midtown Atlanta

• Expect typical rush-hour traffic, especially around the I‑75 / I‑285 “Cobb Cloverleaf” and into Marietta

From Buckhead / Brookhaven / Sandy Springs

• Travel times vary significantly at rush hour, so build in extra time for appointments and procedures

From South Metro (Airport, College Park, East Point)

On large hospital campuses like Kennestone, common experiences include:

Common Hospital Choices by Area

*People’s actual choices depend heavily on insurance, physician network, and medical need, not just geography.

What This Means for You

If you live in central or east Atlanta, you might:

• Use a closer hospital for routine or urgent but not highly specialized care
• Be referred to Kennestone only if your doctor or network prefers it for certain services

If you live in Cobb County or Northwest Atlanta, you might:

• Treat Kennestone as your primary hospital
• Have primary care and specialists who admit patients mainly to Wellstar hospitals

Insurance, Referrals, and Networks

In the Atlanta area, access to Kennestone depends on:

• Your health insurance plan (HMO, PPO, employer plan, marketplace plan, Medicare/Medicaid)
• Whether your primary care physician (PCP) and specialists are in the Wellstar network
• Whether your plan requires prior authorization for hospital services

Steps many Atlanta residents follow:

1. Check your insurance card
   Look for the name of the network or health system listed (if any).

2. Call the member services number
   Ask directly: “Is Wellstar Kennestone Hospital in Marietta considered in-network for my plan?”

3. Confirm with your doctor’s office
   If your doctor is sending you there, ask:

   • “Are you in-network with my plan?”
   • “Will this procedure or admission at Kennestone be in-network?”

📝 Tip: For non-emergency procedures, always get a clear, written estimate from the hospital’s billing or pre-registration department when possible.

Planning a Visit: Appointments, Check-In, and What to Expect

Scheduling Non-Emergency Care

  • A pre-admission or pre-surgical team to review your medical history and instructions

Questions to ask when they call:

• “What building and suite number is my appointment in?”
• “Which parking deck should I use?”
• “How early should I arrive for check-in?”

Day-of-Visit Basics

Using Kennestone in an Emergency

If you are in Cobb County or Northwest Atlanta and call 911:

• Emergency responders typically decide where to take you based on:
  • Your condition
  • Proximity to appropriate facilities
  • Available resources at the time

If you are driving yourself or bringing someone to the hospital from somewhere in the Atlanta area:

• It’s important to know where the Emergency Department entrance is located at Kennestone, which may be separate from the main hospital entrance
• Traffic on I‑75 and surface streets around Marietta can be heavy at peak times, so factor that into your decision when it is safe to do so

Most insurance plans cover true emergencies at out-of-network hospitals differently from routine care, but:

• Coverage rules vary
• It’s still worth understanding how your plan defines an emergency

Kennestone for People Relocating to Atlanta

If you’re moving to Atlanta and planning to live in or near:

• Marietta, Kennesaw, Smyrna, Mableton, or Vinings, or

then Wellstar Kennestone may become:

• Your nearest major hospital
• The primary inpatient site for Wellstar-affiliated doctors you choose in the area

Steps many newcomers take:

1. Pick a primary care provider (PCP)
   Decide whether you want your care anchored within Wellstar, Piedmont, Emory, Grady, or another system.

2. Confirm hospital affiliations
   Ask your new PCP:

   • “If I ever need hospital care, where do you usually admit or refer patients?”

3. Map out emergency options
   Note the closest:

   • Emergency departments
   • Urgent care centers
   • After-hours clinics

From there, you can decide whether Kennestone is likely to be your main hospital or one of several options.
