Grand Junction and Mesa County · Ambulance costs for 2027

How Much Is an Ambulance Ride on Medicare in Grand Junction?

Under Original Medicare, you pay 20% of the Medicare-approved amount after the Part B deductible. On the 13 general Medicare Advantage plans in Mesa County, a ground ambulance costs $245 to $350 for 2027. Air ambulance is where the plans really differ: eight charge 20%, the other five charge a flat $275 to $1,800.

What Medicare pays for an ambulance

Medicare.gov puts it simply: Part B covers ground ambulance transportation, and after the Part B deductible "you pay 20% of the Medicare-approved amount." Two conditions apply. Any other way of getting there has to put your health at risk, and Medicare covers the trip only "to the nearest appropriate medical facility that's able to give you the care you need."

Air transport is covered when you need "immediate and rapid transport that ground transportation can't provide." In western Colorado, that usually means a long distance, bad roads or a condition where minutes matter.

A key protection is easy to miss. Under federal rules for ambulance payment, ambulance companies must accept Medicare's allowed charge. Your 20% is figured on Medicare's approved amount, and the company can't bill you for the rest of its list price. That matters here, because the list prices are high.

What the Grand Junction ambulance actually bills

Inside Grand Junction, the 911 ambulance is the Grand Junction Fire Department's. It posts its rates. The GJFD 2026 rate sheet, in effect from March 1, 2026 through February 28, 2027, lists:

• $1,083 for a basic life support transport
• $1,479 for advanced life support (ALS 1)
• $2,683 for critical care transport
• $26 a mile on top of the base rate

Those are billed charges, not what a Medicare patient owes. On Original Medicare, your share is 20% of Medicare's lower approved amount. On a Medicare Advantage plan, you pay the plan's copay or coinsurance. The city's ambulance page says billing is handled by Wittman Enterprises (1-800-906-6552). Call that number if a bill doesn't match your Medicare Summary Notice or your plan's Explanation of Benefits.

The air side is CareFlight of the Rockies. According to Intermountain Health, it has flown in western Colorado since 1976. As of 2023, its two airplanes flew from Grand Junction Regional Airport and its helicopters were based in Rifle and Montrose, covering about 250 miles, including eastern Utah.

Every 2027 Mesa County plan, side by side

I matched the ambulance section of CMS's 2027 plan benefit file to the 13 general plans on the 2027 Mesa County landscape, sorted from lowest to highest ground copay:

Source: CMS 2027 plan benefit file, section B10a, Mesa County general plans; caps from the CY2027 landscape. Listing a plan is reporting, not a recommendation, and we do not offer every plan available in your area.

The ground column is fairly tight, a $105 spread. The air column isn't. Here's what I'd notice:

• Eight plans charge 20% for an air ambulance. Twenty percent of a flight's approved amount is often thousands of dollars. On those plans, a single flight can use up much of the yearly cap.
• Anthem charges the same $275 for air as for ground. Its cap is the highest on the list, though, at $9,850.
• Humana charges a flat $630 or $1,800 for air. You know the number ahead of time, but $1,800 is real money.
• None of the 13 waives the copay if you're admitted. CMS's file shows "no" on every plan. You can owe an ambulance copay and a hospital copay for the same emergency.

A caveat about the yearly cap: every dollar above counts toward the plan's in-network maximum. Emergency ambulance trips get in-network treatment even when the company isn't in the plan's network. So the cap is the most an ambulance could cost you in 2027, along with everything else you used that year.

"Per trip" or "per day"? Read the Evidence of Coverage

CMS's file shows how much each plan charges, but not what counts as one charge. For that, you need the plan's Evidence of Coverage. Humana's is clear. The 2027 Evidence of Coverage for HumanaChoice H5216-223 charges $325 for a ground ambulance and $630 for an air ambulance "per date of service regardless of the number of trips." It charges the same amounts out of network, and it says emergency ambulance transportation is covered worldwide.

That wording matters in the Grand Valley. Say a ground ambulance takes you to St. Mary's and you're flown to Denver later that day. On a per-date plan, that could be one ground copay and one air copay, not a new charge for each leg. Other plans may charge per one-way trip. Look up the ambulance row in Chapter 4 of your plan's Evidence of Coverage before you assume either.

When prior authorization comes in

All 13 plans list prior authorization for ambulance services in CMS's file. That doesn't apply to a 911 call. Humana's Evidence of Coverage, like every Medicare Advantage plan's, says you don't need approval in a medical emergency. Call 911 and sort out the paperwork afterward.

Prior authorization matters for scheduled rides: a transfer between hospitals, a trip home from a nursing facility, or a stretcher ride to treatment. The city's ambulance page says a long-distance transport needs a Physician's Certification Statement documenting medical necessity before the crew rolls. On an Advantage plan, the plan's approval sits on top of that. If either is missing, the ambulance company may hand you an Advance Beneficiary Notice. Medicare.gov says that notice means you could owe the whole bill. Read it before you sign.

On Original Medicare with Medigap

With Original Medicare alone, you pay the Part B deductible ($283 in 2026; CMS hadn't announced the 2027 figure as of November 14) and 20% of the approved amount, with no yearly cap. For a flight, that 20% is the open-ended risk.

A Medigap Plan G or Plan N pays that 20% in full after the Part B deductible. Plan N's $20 and $50 copays apply to office and emergency room visits, not ambulance rides. There's no network and no plan-level prior authorization, so any ambulance company that bills Medicare is covered the same way. The limit is Medicare's own medical-necessity rule: if Medicare denies the trip, Medigap pays nothing either.

How I'd weigh ambulance costs in a 2027 decision

1. Think about distance, not just the copay. If you live in town near St. Mary's or Community Hospital, a ground ambulance spread of $245 to $350 is a small part of the decision. If you live in Collbran, Gateway or Mack, a flight is more likely, and the air column matters more.
2. Pair the air cost with the cap. A plan that charges 20% for flights and has a $4,900 cap protects you differently than one with a flat $1,800 and a $7,850 cap.
3. Remember the hospital copay comes too. No Mesa plan waives the ambulance charge if you're admitted. Our 2027 Grand Junction hospital copay breakdown shows the other half of that bill.
4. Leave subscription programs for a separate decision. An air-medical membership is a private product with its own terms, not Medicare coverage. Weigh it against your plan's air cost, not instead of reading it.

Open Enrollment runs through December 7, and a new plan starts January 1. For what Medicare will and won't treat as an ambulance trip in the first place, see our Colorado ambulance coverage explainer.

How we know all this: the Medicare On Main Data Desk backs every article with public data. Here that means Medicare.gov's ambulance coverage page, the federal ambulance fee-schedule regulation, CMS's 2027 plan benefit and landscape files, Humana's 2027 Evidence of Coverage for HumanaChoice H5216-223, the City of Grand Junction's ambulance billing page and 2026 rate sheet, and Intermountain Health's description of CareFlight of the Rockies, all read November 14, 2026. A plan's final documents can differ, so confirm benefits in its Summary of Benefits and Evidence of Coverage. Carrier names are factual reporting, not endorsement.
