HCPCS Code T2003: Non-Emergency Transportation; Encounter/Trip

## **T2003 documentation requirements** Clear documentation is essential to justify medical necessity and support reimbursement. ### **Medical necessity and request** Keep a signed transportation request or authorization from a qualified practitioner or care coordinator. Records should also explain why the patient cannot safely use public or private transportation—for example, due to wheelchair dependence, oxygen use, limited mobility, or other medical restrictions. ### **Patient and provider information** Include the patient’s full name, Medicaid ID (if applicable), and contact details. Record the driver’s name, identification number (if issued), and the vehicle’s license plate number used for the trip. ### **Trip and transport details** Document the service date(s), number of trips, and whether transport was one-way or round-trip. Provide pick-up and drop-off addresses, appointment time, and the healthcare facility visited. Note the vehicle type (e.g., sedan, wheelchair van) and any special accommodations. If mileage is billed separately, include odometer readings or mileage totals. ### **Diagnosis linkage** When required by the payer, enter a diagnosis pointer to connect the trip to the primary diagnosis in the medical record. This ensures the transportation is tied to a covered medical service. ### **Claim submission requirements** Record the billed charge for the service and ensure the claim form is signed and dated by the provider or authorized representative. Include provider identifiers (e.g., NPI, Medicaid ID, or tax ID). Submit only attachments required for adjudication, such as prior authorization approval, and number pages if sending multiple documents for the same patient. ### **No-show reporting** If a patient does not appear for a scheduled trip, maintain a no-show log with the driver’s arrival time, wait time, and any follow-up actions. Some payers allow limited reimbursement for no-shows when properly documented.

## **T2003 billing requirements** Billing for T2003 depends heavily on payer policies, particularly Medicaid, which is the primary source of NEMT benefits in the United States. ### **Units** Bill per encounter/trip, not per mile. Each one-way trip is counted as a separate billable encounter under T2003. If the patient requires both pick-up and return transport, bill two encounters. When mileage is reimbursable, it must be billed separately using codes such as A0425 (ground mileage, per statute mile). Always ensure the number of encounters billed matches the trip logs and patient records. ### **Payer-specific rules** Medicaid is the primary payer for non-emergency medical transportation (NEMT) in the United States. Most state Medicaid programs cover T2003 as part of the NEMT benefit, but they typically require prior authorization and restrict coverage to trips arranged through approved or enrolled transportation providers. Medicare, by contrast, does not generally cover non-emergency transportation. The only exceptions are narrow, such as patients with end-stage renal disease (ESRD) who need transport to dialysis treatments, or in other rare cases where a physician certifies medical necessity. Some offer transportation benefits, often managed through contracted vendors. Coverage usually requires strict documentation—such as trip logs, medical justification, and sometimes prior approval—to ensure compliance with the plan’s management of transportation services. ### **Prior authorization** Prior authorization is a common requirement for T2003 transportation services claims. Most Medicaid programs and many commercial plans mandate that providers obtain approval in advance or schedule the trip through a designated broker (e.g., LogistiCare/ModivCare). Without authorization, claims are frequently denied, regardless of whether the trip occurred.

## **Applicable modifiers** HCPCS code T2003 does not have nationally required modifiers under Medicare, but many state Medicaid programs apply their own modifiers to distinguish where and how non-emergency medical transportation services are delivered. These modifiers help define the service setting and may affect reimbursement rates. - **U1**: Metro/Urban county - **U2**: Rural county - **U3**: Micro/Suburban county - **SE**: State and/or federally funded program or service Because these are state-specific, providers should only use them when instructed by the payer. Some Medicaid agencies also mandate the SE modifier when transportation services are reimbursed under state- or federally funded programs. Always verify the applicable program’s billing manual before submitting claims.
