What is the Medicare fee schedule for ambulance services?

The Medicare Ambulance Fee Schedule is a national Part B payment system that uses location-specific base rates and mileage fees to reimburse emergency and non-emergency medical transportation.

How Payment Rates Work

  • Base Rate + Mileage: Total payment combines a flat base rate (determined by the level of service and geographic location) plus a per-mile rate for "loaded" miles (miles traveled while the patient is on board).
  • Service Levels: Relative Value Units (RVUs) scale payments based on care intensity, ranging from Basic Life Support (BLS, RVU 1.00–1.60) up to Specialty Care Transport (SCT, RVU 3.25) and fixed/rotary wing air ambulance.
  • Geographic Adjustments: Rates vary significantly by ZIP code and locality to account for regional differences in operating costs, plus specific adjustments for urban, rural, and super-rural regions.
  • Patient Responsibility: Medicare Part B covers 80% of the approved amount after you meet the yearly Part B deductible, leaving you responsible for the remaining 20% coinsurance.

You can look up exact dollar amounts for your specific region through the CMS Ambulance Fee Schedule Public Use Files.

What are the Medicare billing guidelines for ambulance services?

Medicare Part B covers and pays for medically necessary ground and air ambulance transportation when other methods of travel are dangerous to the beneficiary's health.

Core Billing Requirements

  • Medical Necessity: The patient's condition must make safe alternative transport medically contraindicated. For non-emergency transports, the patient must be bed-confined or require specialized medical personnel/equipment during the trip.
  • Actual Transport: Actual movement of the patient to an appropriate destination (such as the nearest appropriate hospital or skilled nursing facility) must occur.
  • Documentation: Providers must maintain complete trip/run sheets showing medical necessity, and secure a valid Assignment of Benefits (AOB) signature or document why the patient could not sign. For scheduled, repetitive non-emergent trips, a Physician Certification Statement (PCS) is required.

Coding and Modifiers

  • HCPCS Codes: Claims are billed using specific Ambulance Fee Schedule codes based on the level of service provided (such as A0428 for Basic Life Support or A0427 for Advanced Life Support emergency), alongside mileage codes like A0425.
  • Origin and Destination Modifiers: Two-character modifiers must be appended to the service and mileage codes (e.g., RH for residence-to-hospital) to denote where the trip started and ended.
  • Point of Pickup (POP): The 5-digit ZIP code of the pickup location must be reported on the claim for correct geographic rate adjustments.

How much does Medicare pay for an ambulance service?

Under Original Medicare, Medicare Part B pays 80% of the Medicare-approved amount for qualified ambulance services. You are responsible for paying the remaining 20% coinsurance out-of-pocket, after satisfying your annual Part B deductible.

Cost Breakdown

  • Medicare’s Share: 80% of the Medicare-approved rate. By law, ambulance companies cannot charge you more than the official Medicare-approved rate (there are no "excess charges").
  • Your Share (Coinsurance): 20% of the approved rate. For a typical ground ambulance ride, this out-of-pocket cost usually ranges between $200 and $400.
  • Annual Part B Deductible: You must meet the annual deductible before Medicare begins paying its share.

Requirements for Medicare to Pay

Medicare will only cover its portion of the bill if the ride meets strict criteria:

  1. Medical Necessity: You require immediate medical attention, and transport by any other vehicle (like a taxi or car) would endanger your health.
  2. Approved Destination: The ambulance must take you to the nearest appropriate medical facility that can provide the necessary care (usually a hospital ER or skilled nursing facility).
  3. Air Ambulance: Medicare may cover transport by airplane or helicopter, but only if ground transportation is impossible, too slow, or otherwise threatens your survival.

Supplementary Insurance & Coverage Variances

  • Medigap (Medicare Supplement): If you have a Medigap policy, it will typically pay for all or a portion of your 20% coinsurance.
  • Medicare Advantage (Part C): If you are enrolled in a private Medicare Advantage plan, your costs are determined by that specific insurer. Instead of a 20% coinsurance, you will usually pay a predetermined flat copayment per trip, and prior authorization rules may apply.

Can an ambulance bill be negotiated?

Yes, an ambulance bill can often be negotiated or reduced.

Steps to Negotiate an Ambulance Bill

  • Request an itemized bill: Ask for an itemized statement and the Patient Care Report to check for coding errors, such as being billed for Advanced Life Support (ALS) instead of Basic Life Support (BLS), or incorrect mileage. Guidance on identifying these errors is outlined in the California Patient Guide.
  • Offer a lump-sum payment: Call the billing department and offer a one-time, immediate partial payment. Providers often accept a reduced cash amount (sometimes 20% to 50% off) rather than risk getting nothing.
  • Ask for hardship or charity care: Explain if you are facing financial hardship. Many municipal and private providers offer financial assistance programs, hardship waivers, or sliding-scale reductions.
  • Set up a payment plan: If a full discount is not granted, ask for a zero-interest, manageable monthly payment plan.
  • Check local and state rules: Look into your local municipal rules or state laws regarding emergency and surprise billing protections. Detailed negotiation strategies are also covered by CareRoute and CBS News.
