Specialty billing Ambulance & EMS
Your crews save lives. They shouldn't have to worry about paperwork.
Our EMS billing services are built specifically for ambulance operations. Whether you run a municipal fire department, a private ambulance company, or a hospital-based EMS program, your department deserves to be paid correctly for the trips it runs — not by chasing patients with aggressive collection letters, but through ambulance billing services that understand the difference between a life-saving run and a paperwork nightmare.
EMS billing focus
About the Work
The run report has to carry enough detail to get the claim paid, and your crews already have a lot to think about on a call.
The money from those claims goes back into your department. You shouldn't have to leave any of it on the table.
Why EMS Billing Is Different
Ambulance claims aren't like office-visit claims. There's no waiting room, no insurance card handed over at check-in, and no calm moment to double-check paperwork. Here's what makes an EMS billing company completely different from a typical medical biller.
Incomplete patient info at the scene often turns into an unpaid claim later. Medicare and insurers decide whether to pay based on what's written in the patient care report (PCR), not necessarily on what actually happened during the call. A documentation gap can cost your department real money.
Medicare pays very differently depending on the level of service performed. Get the difference between Advanced Life Support (ALS1, ALS2) and Basic Life Support (BLS) wrong, and your claim either gets denied outright or reimbursed at a fraction of what it should be. Add in Specialty Care Transport (SCT), loaded mileage calculations, and origin/destination modifiers, and it's easy to see why so many ambulance revenue cycle management programs struggle.
The Ground Emergency Medical Transportation (GEMT) supplemental payment program, sometimes called GEMT/CPE, exists to help Medicaid-eligible transports get reimbursed closer to actual cost. GEMT programs are run by individual states, and the filing process can be complicated and time-consuming. Ask us whether your state's program applies to your department.
The No Surprises Act reshaped air ambulance billing services, protecting patients from many surprise bills for air transport. Ground ambulance services aren't covered by the No Surprises Act's balance-billing protections, so state laws apply, and they vary widely. Getting this wrong can mean compliance risk and community backlash as well as lost revenue.
The MedixCode Solution
We built our outsourced ambulance billing process around the way EMS actually operates, not the way a typical medical office does.
We work inside your existing ePCR and billing systems using the access you grant us. No new software for your crews, and you keep ownership of your data.
Insurance discovery finds coverage for patients who were transported without insurance details captured at the scene.
We code each ALS, BLS and SCT transport to the level the patient care report supports, and appeal denials with that documentation.
Where your state runs a GEMT or Medicaid supplemental payment program, we talk through what it requires and how your billing data supports it.
We follow up on patient balances respectfully and within the billing policies your department sets.

Book a Free ConsultationHCPCS Coding
Ambulance claims use HCPCS codes to describe the level of service, plus origin and destination modifiers that tell Medicare where the patient was picked up and dropped off.
| Code | What It Covers |
|---|---|
| A0425 | Ground mileage, per statute mile (loaded miles only) |
| A0427 | ALS1 – emergency |
| A0429 | BLS – emergency |
| A0426 / A0428 | Non-emergency ALS/BLS |
| A0433 | ALS2 |
| A0434 | Specialty Care Transport (SCT) |
| A0430 / A0431 | Air ambulance |
| A0998 | Response and treatment, no transport (Medicare doesn't pay this code; some other payers do) |
Origin/destination modifiers (pairs like RH, HH, NH, SH ) combined with letters such as D, E, G, I, J, and X tell the payer exactly where a patient started and ended their trip. We code these on each claim, along with less common modifiers such as GM for multiple patients transported at once.
Regulatory Update
A few regulatory changes are worth knowing about, even if you never touch a claim yourself.
A modest bump to the base ambulance fee schedule for 2026.
Extended through December 31, 2027 — meaningful for rural coverage areas.
Real money for departments covering large, sparsely populated areas.
Medicare's Ambulance Inflation Factor for 2026 is 2.0% (CMS transmittal R13464CP, November 14, 2025). Section 6203 of the Consolidated Appropriations Act, 2026 (February 3, 2026) extended the temporary ground ambulance add-ons through December 31, 2027: 2% for urban pickups, 3% for rural pickups, and a 22.6% base-rate bonus for super-rural pickups.
Source: CMS.
Separately, CMS runs the Medicare Ground Ambulance Data Collection System (GADCS). A ground ambulance organization that CMS selects and that doesn't report sufficient data faces a 10% reduction in its Medicare ambulance fee schedule payments for the following year, unless it gets a hardship exemption (42 CFR 414.610(c)(9) and 414.626). CMS has said it will address future data collection in CY 2028 rulemaking. We can help you keep track of whether you've been selected.
Community-First Revenue
Fire departments are part of their communities. Many of the people you bill are your neighbors. That's why compassionate billing matters as much as clean coding.
We help departments set up hardship policies and patient-friendly payment plans, and can bill under a subscription program your department already runs, recovering revenue without the reputational risk of aggressive collections. You shouldn't have to choose between your collection rate and how the community sees you.
The people you bill today are the same people who'll wave at your crews at the grocery store tomorrow.
Results That Matter
Your reports break claims out by payer, provider, location and CPT, so you can follow your runs from claim to payment.

FAQ
Common ambulance and EMS billing questions we hear from fire departments and operators. More questions? See our FAQ
An ambulance claim is built from the patient care report, the level of service provided (ALS or BLS), loaded mileage and origin/destination modifiers. Payers use these details to decide medical necessity and payment. Missing documentation is a frequent reason claims get denied or underpaid.
ALS (Advanced Life Support) covers transports with advanced interventions, such as IV medications or cardiac monitoring, and pays at a higher rate. BLS (Basic Life Support) covers transports without those interventions. Billing the wrong level, in either direction, risks a denial or lost revenue.
Yes, under the medical necessity rules in 42 CFR 410.40. Medicare requires documentation that transport by any other means would have endangered the patient's health, and a Physician Certification Statement for certain non-emergency transports.
A Physician Certification Statement (PCS) is documentation from a physician or other authorized practitioner confirming that ambulance transport was medically necessary. Medicare requires it for scheduled, repetitive non-emergency transports and for some unscheduled non-emergency transports, and missing PCS paperwork is a frequent cause of denials.
Common reasons are incomplete PCR documentation, missing medical necessity justification, incorrect level-of-service coding, missing PCS forms for non-emergency transports, and coordination-of-benefits errors when a patient has more than one insurance plan.
