Non-Emergency Medical Transportation (NEMT) Billing Services
NEMT billing is a high-volume, low-margin business. Providers move patients to dialysis, therapy, and clinic visits, and each trip becomes a small claim. Small errors repeat across hundreds of trips, so a weak process can cost real money quickly.
Most NEMT revenue comes through Medicaid. In many states, that means working with a broker or managed care contractor that sets its own trip rules, portals, and data requirements. Trip logs, driver records, and member eligibility all have to line up with the claim. Westmont connects NEMT providers with vetted billing experts who understand this trip-level workflow.

Billing challenges in NEMT
Broker and plan rules that differ by state. Each state and contractor sets its own codes, modifiers, and submission formats. Billers keep a payer guide for each contract and update it when the rules change.
Trip authorization and eligibility. Trips usually must be approved or assigned before they happen, and the member must be eligible on the date of service. Billers match each trip to its authorization and check eligibility before submission.
Trip documentation. Payers may ask for pickup and drop-off times, mileage, the vehicle used, and a signature or alternate proof of the ride. Billers audit trip logs for gaps before claims go out.
Mileage and one-way versus round trip. Many programs count each leg as a separate trip and calculate mileage in specific ways. Billers check how each payer wants miles and legs reported.
Rate and level-of-service mismatches. A wheelchair or stretcher trip must be billed at the level that matches the member's approved need. Billers compare the dispatch record, the approval, and the claim.
Late and rejected submissions. Many payers have short filing windows and strict data validation. Billers track filing deadlines and fix rejections quickly.
Driver and vehicle compliance. Payers may check driver credentials, vehicle inspections, and insurance. This is not billing alone, but a lapse can stop payment. A good billing partner flags it early.

Frequently asked questions
What is NEMT billing?
NEMT billing is the process of submitting claims or invoices for non-emergency rides to medical appointments. It includes matching trips to approvals, applying the right trip and mileage codes, and following each payer's format. Most NEMT billing is tied to Medicaid, either directly or through a broker or managed care plan.
Does Medicare pay for NEMT?
Original Medicare generally does not cover non-emergency rides, with narrow exceptions. Some Medicare Advantage plans offer transportation as a supplemental benefit. Details vary by plan and year, so check each plan's current benefit rules and contract terms before billing.
Who do NEMT providers bill?
It depends on the state. Some Medicaid programs pay providers directly. Many use a statewide or regional broker, and some route trips through managed care organizations. Your payer is often the broker, not the state. Your contract will say where and how to submit claims.
What documentation do NEMT claims need?
Requirements vary, but payers commonly want the member's identity, the approved trip, pickup and drop-off details, times and mileage, and proof the trip took place. Keep complete trip logs and driver records, and ask each payer which items are required for audits.
How can a billing partner reduce NEMT denials?
A billing partner can check trip data and eligibility before submission, match claims to approvals, and track filing deadlines. When a claim is rejected or denied, they correct and resubmit it. Consistent trip documentation on your side makes this much easier.
