It is stated that the ambulance service is covered, and can be reimbursed through Medicaid using ambulance modifiers. However, with so many medical billings and claims changes, how are ambulance modifiers utilized properly to avoid strenuous or legal situations?

Ambulance and Its Work
Everyone knows the purpose of the ambulance. The ambulance service provider provides the facility of an ambulance in such cases where our patient cannot access any other means of transportation and must wait for his vehicle while he is surviving and looking for help to save his life in danger.
How Can Ambulance Modifiers Be Used?
The service of ambulance service is not only for the land but also for the air and water. But here are the covered CPT codes for ground ambulances, which also invoke both water and air transportation. There’s a quick identification of these codes, based on the following facts distance traveled, services given to the patient inside the ambulance, and the patient’s health condition at the time of the ambulance service call.
Below is a list of CPT codes and modifiers used for the ambulance transportation service, along with the short descriptions:
- CPT A0425 – Ground distance per statute mile.
- CPT A0426 – The code is used for non-emergency ambulance transport, advanced life support, and ALS1 level, which includes medical supplies in the ambulance, but these medical supplies do not only include the administration of approved medications, nebulizers, IV Sub Q, peripheral venous puncture, sublingual, and IM.

- CPT A0434 – Special Care Transport (SCT)
Ambulance Services Modifiers

The HCPCS provides a range of modifiers that can be employed; these modifiers are made up of a combination of alphanumeric characters.

- Modifier J – ESRD freestanding facility
- Modifier N – Facility providing skilled nursing,
- Modifier P – Medical practice

What Takes Place When Incorrect Billing Is Done For Ambulance Transportation?
If the modifier in a billing claim doesn’t tell the ambulance’s origin and destination of the ambulance, then the claim should be considered inappropriate and can be rejected.
For Example, if an emergency ambulance service is called for the patient and the patient reaches the Physician’s clinic from his residence. The claim will be billed under the modifiers of P & R. Where refers to the residence and P refers to the Physician.
