The 5 Top-Rated Urgent Care Centers and Walk-In Clinics in Key West (Updated 2025)

Finding fast, professional medical assistance in Key West requires knowing the key players. While the Lower Keys Medical Center handles true emergencies, these five facilities are your best bet for convenient, non-critical care, often with shorter wait times and specialized services for visitors.

1. Advanced Urgent Care of the Florida Keys

This center is a powerhouse for immediate care, specifically designed to handle a wide array of illnesses and injuries. It is a popular choice for both tourists and locals due to its comprehensive on-site capabilities and experienced staff.

  • Key Services: Advanced Urgent Care is staffed by experienced ER doctors and nurses, providing a higher level of walk-in care than many standard clinics. Services include digital X-ray, CT Scan, lab work, ultrasound, and specialized treatments like Hydration Therapy.
  • COVID-19 & Travel Medicine: They offer a full range of COVID-19 testing, including PCR, Rapid Antigen, and Antibody tests, making it a critical resource for travelers needing documentation.
  • Accessibility: The Key West location is part of a larger network that includes centers in Marathon and Key Largo, providing continuous care options throughout the Keys.
  • Insurance & Payment: The clinic accepts most major insurance plans, including Medicare, Blue Cross / Blue Shield, Cigna, and Tricare. They also proudly offer discounted cash pricing, which is a significant benefit for uninsured patients or international tourists.
  • Typical Hours: Generally open daily from 8 AM to 8 PM, though it is always recommended to call ahead for the final patient admission time.

2. Key West Urgent Care & Family Doctor

Operating since May 2005, this facility is one of the most established alternatives to the emergency room in Key West, blending urgent care convenience with the continuity of a family doctor.

  • Dual Focus: This center provides both urgent care for acute issues (colds, flu, minor accidents, sore throat) and primary care services, including annual physicals and chronic disease management.
  • Occupational Medicine: A notable specialty is Occupational Medicine, offering services like pre-employment and annual physicals, which is vital for local businesses and employees.
  • Onsite Testing: They offer onsite COVID-19 testing and treatment for various minor procedures.
  • Important Note: While they offer urgent care, their hours can sometimes be more limited than other dedicated walk-in clinics, with some days closing earlier. Always confirm current operating hours before visiting.

3. Mount Sinai Medical Center Primary Care, Walk-in Clinic and Diagnostic Center

This is one of the freshest and most significant medical updates for Key West in 2025. Mount Sinai, a major health system, expanded its presence by opening a new, comprehensive facility on April 14, 2025.

  • New Entity: The introduction of a Mount Sinai facility is a game-changer, bringing a high level of coordinated care and major hospital resources to the island.
  • Services Offered: The center combines Primary Care, a dedicated Walk-in Clinic, and a Diagnostic Center, making it a one-stop-shop for routine and immediate non-emergency needs.
  • Impact: This expansion is part of a broader trend of major health systems investing in the Florida Keys, promising improved long-term healthcare access for all residents and visitors.

Navigating Key West Medical Services: When to Choose Urgent Care vs. the ER

The primary difference between a Key West urgent care center and the Lower Keys Medical Center Emergency Room is the severity of the condition. Choosing the right location saves you time, money, and ensures the ER is available for life-threatening situations.

When to Use a Key West Urgent Care or Walk-In Clinic

Urgent care facilities are designed for conditions that require immediate attention but are not life-threatening. They are the ideal choice for a Key West doctor visit when your primary care physician is unavailable. Common treatable conditions include:

  • Minor cuts, scrapes, and burns
  • Sprains and strains (often with on-site X-ray capability)
  • Colds, flu, fever, and sore throats
  • Ear infections, eye infections, and rashes
  • Urinary tract infections (UTIs)
  • Allergy treatment and minor asthma attacks
  • COVID-19 testing and travel-related medical needs

Advanced Urgent Care of the Florida Keys and Key West Urgent Care & Family Doctor are excellent examples of facilities equipped to handle all these common ailments efficiently.

When to Go Directly to the Lower Keys Medical Center Emergency Room

The Emergency Department at Lower Keys Medical Center (LKMC) is equipped for the most critical, life-threatening conditions. If you are experiencing any of the following, bypass the walk-in clinics and call 911 or head directly to the LKMC Emergency Room:

  • Chest pain or signs of a heart attack or stroke
  • Severe bleeding that won't stop
  • Major injuries, deep lacerations, or broken bones where the bone is visible
  • Difficulty breathing or severe respiratory distress
  • Sudden paralysis or loss of consciousness
  • Serious head injuries

The Future of Healthcare in the Florida Keys: Key 2025 Expansions

The year 2025 marks a period of significant investment and expansion in Key West's healthcare infrastructure. These developments are enhancing the quality of care available to everyone in the Lower Keys, from emergency services to specialized treatments.

Major Community Health Systems (CHS) Investment

Community Health Systems (CHS) has unveiled a proposal for a major investment exceeding $350 million to expand and improve healthcare for Key West residents. This focus on long-term infrastructure suggests a commitment to enhancing the overall medical ecosystem, which will indirectly improve the capabilities and resources of all local urgent care facilities.

Baptist Health’s New Cancer Care Facility

In a separate but equally important development, Baptist Health is expanding its specialized services in the Florida Keys. They are opening a new Key West facility in Summer 2025, which will offer advanced cancer therapies and services locally. While not an urgent care center, this expansion demonstrates the trend of major health networks prioritizing high-level medical care on the island, which raises the standard for all practitioners.

The Rise of Specialized and Tourist-Focused Care

Beyond traditional clinics, specialized services are also emerging. The existence of entities like Tourist Life Clinic, which focuses on 24/7 non-emergency urgent care for tourists without the hassle of insurance or waiting rooms, highlights the growing demand for convenient, no-fuss medical access. Furthermore, the licensing update for "FLORIDA KEYS URGENT CARE, LLC" with a current effective date in March 2025 shows the continued regulatory activity and growth in the walk-in sector.

Whether you're dealing with a mild sunburn, a sudden stomach bug, or need a last-minute COVID test before a flight, Key West's urgent care options are robust and continually improving. By knowing the distinction between a walk-in clinic and the emergency room, and by having the contact information for the top providers—especially the newly expanded Mount Sinai facility—you are well-prepared to handle any minor medical setback while enjoying the beauty of the Florida Keys.
