HCA Florida Oak Hill South Emergency Is Open: Spring Hill's New 24/7 ER

HCA Florida Oak Hill South Emergency, the new freestanding emergency room in Spring Hill, took its first patients on Monday, August 10, 2026. It’s at 11242 Spring Hill Drive, near the intersection with Mariner Boulevard, and it’s open 24 hours a day, seven days a week. The phone number is (352) 606-7222.

It’s part of HCA Florida Oak Hill Hospital, and it’s Hernando County’s newest emergency room. Here’s what it treats, what it can’t do, what it costs, and how it fits with the other ER in Spring Hill.

It’s in Spring Hill, not at the Brooksville hospital

This detail matters for navigation. The new ER sits on Spring Hill Drive in Spring Hill. Its parent hospital, HCA Florida Oak Hill Hospital, is at 11375 Cortez Boulevard in Brooksville, a separate campus in a different town.

Spring Hill already had one emergency department: TGH Spring Hill, the Tampa General hospital at 10461 Quality Drive (formerly Bravera Health Spring Hill). Oak Hill South is a second option on the Spring Hill Drive corridor, and it’s a different kind of facility. That difference is the most important thing to understand before you need it.

What a freestanding ER actually is

This isn’t an urgent care clinic, and it isn’t a full hospital. A freestanding emergency room is a real ER, staffed and equipped for genuine emergencies, but it isn’t attached to a hospital building.

According to HCA, Oak Hill South has:

• Ten private treatment rooms plus a dedicated trauma room
• CT scans, X-rays, and ultrasound on site
• An on-site laboratory
• Emergency care for kids and adults, around the clock

HCA lists the conditions it’s equipped to diagnose and treat as injuries such as fractures and cuts, stomach and abdominal pain, breathing trouble and upper respiratory infections, chest pain and heart attacks, and stroke and seizures.

The catch: what happens if you’re admitted

A freestanding ER can stabilize and treat you, but it has no inpatient beds. If you need to be admitted, you’ll be transferred to a hospital. Oak Hill South’s parent hospital is Oak Hill in Brooksville.

That’s the practical difference between Spring Hill’s two ERs. TGH Spring Hill is a hospital, so if you need admission there, you stay in the same building. Oak Hill South is freestanding, so admission means a transfer.

Quick gut check on where to go:

• Life-threatening (chest pain spreading to the arm or jaw, stroke signs like face droop or slurred speech, uncontrolled bleeding): call 911. EMS decides the fastest, right destination.
• Urgent but not catastrophic (fractures, deep cuts, severe abdominal pain, high fever): either Spring Hill ER can handle it.
• Minor (sinus infection, mild sprain, prescription refill): an urgent care or your primary doctor is cheaper and faster.

What it’ll cost you: read this before you go

A freestanding ER that belongs to a hospital generally bills like a hospital emergency room. Expect emergency co-pays, deductibles, and facility fees, not urgent-care pricing. A closer building doesn’t mean a smaller bill.

If it’s a genuine emergency, that’s what ER coverage is for. But for something minor, the ER is the expensive choice by design. Check your plan’s emergency-room benefits now, before you’re at the registration desk.

How the opening played out

HCA broke ground on June 5, 2025. We previously reported a February 2026 target opening; the build ran longer than that. HCA held a ribbon cutting for the finished building on June 19, 2026, said then that it expected a July opening, and the doors opened to patients on August 10, 2026.

For the latest on services and wait times, check HCA’s Oak Hill South Emergency page or call (352) 606-7222. In a true emergency, don’t call ahead. Call 911.

Correction, September 23, 2026: An earlier version of this article said Spring Hill had no emergency room before this one opened. TGH Spring Hill on Quality Drive has an emergency department. We’ve also updated the facility’s cost and room count to match HCA’s opening announcement.
