What's the difference between a BLS and ALS ambulance?

The total cost of your ambulance ride is heavily dictated by the "Level of Service" deployed to your emergency. Not all ambulances—and not all EMS professionals—are equipped or trained equally. The two primary categories of ground emergency transport are BLS (Basic Life Support) and ALS (Advanced Life Support).

Basic Life Support (BLS)

A BLS ambulance is the standard tier of emergency response. These units are staffed by Emergency Medical Technicians (EMTs) who have completed approximately 150 hours of training.

• Capabilities: CPR, automated external defibrillation (AED), bleeding control, splinting, oxygen administration, and basic patient stabilization.
• When it's used: Non-life-threatening emergencies such as broken bones, minor concussions, or general psych/welfare transports.
• Cost: BLS is the cheapest tier of transport on both the Medicare fee schedule and private provider "Sticker Price" structures.

Advanced Life Support (ALS)

An ALS ambulance operates effectively as a mobile emergency room. These units are staffed by Paramedics, who have completed 1,200 to 1,800 hours of intensive medical training.

• Capabilities: Advanced airway management (intubation), starting IV lines, administering a wide spectrum of powerful medications and narcotics, manual cardiac monitoring, and interpreting EKGs.
• When it's used: Life-threatening emergencies such as cardiac arrest, strokes, severe trauma, severe allergic reactions (anaphylaxis), and active seizures.
• Cost: Due to the expensive equipment and highly trained personnel, ALS transports are billed at significantly higher base rates. CMS further splits ALS into ALS Level 1 and ALS Level 2 (for extremely critical multi-intervention scenarios).
