Billing facilities for NEMT rides: monthly invoices, net terms, and disputes

Facility billing is business-to-business invoicing

When a hospital, nursing home, or clinic agrees to pay for rides, it becomes your customer, and the rider is not the one paying. You bill it the way any vendor bills a business: under a signed agreement, from a rate schedule, on an invoice its accounts payable team can approve without calling you.

Be clear about which rides the facility is paying for. A facility often books rides that someone else pays for:

• Medicaid riders usually ride through the state’s broker or health plan, even when a facility makes the booking. Indiana hospitals, for example, book fee-for-service discharges home through Verida’s facility dispatch line.
• Private-pay residents may pay for their own rides. Bill them or their families, not the facility, unless the facility has agreed to pay.
• Rides the program assigns to the facility. Louisiana’s 2026 managed care manual lists non-ambulance transportation for nursing home residents as included in the facility per diem. Colorado refuses separate payment for nursing facility and group home residents’ rides to services in the facility’s program, unless the facility has no vehicle available, and tells facilities to report the cost on their cost reports. Indiana goes furthest: since July 1, 2023, the nursing facility itself books and reimburses non-ambulance rides for residents on Medicaid, because the facility’s per diem covers them. That includes a downgraded 911 trip for a resident that did not meet ambulance necessity, which the ambulance company bills to the nursing facility.

Only invoice the facility for rides inside the agreement. Everything else goes to the payer that owns it. Winning the agreement in the first place is covered in how to get NEMT facility contracts.

Set the rate schedule before the first ride

Attach the rate schedule to the agreement and date it. An invoice line that matches a signed schedule gives accounts payable nothing to question.

A complete schedule covers:

• Base rate per one-way leg for each service level (ambulatory, wheelchair, stretcher).
• Mileage, and whether it counts loaded miles only.
• Wait time once the free waiting period ends, billed in set increments.
• After-hours, weekend, and holiday rates.
• Extras: an attendant, stair assistance, a second rider.
• Fees for no-shows and late cancellations, with the notice the facility must give to avoid them.
• Minimums, such as a minimum charge per leg.

Two rules keep the schedule safe:

1. Stay consistent with what you bill Medicaid. Colorado’s NEMT claim instructions, for example, want each detail line to carry your usual and customary charge. Read usual and customary charge before you set facility prices well below your standard rates.
2. Never tie the price to referrals. The HHS Office of Inspector General calls this swapping. In its November 2024 guidance for nursing facilities, OIG warns against a facility accepting a discounted price on something its Medicare Part A per diem covers in return for sending the supplier other federal program business that the supplier bills directly. It names ambulance providers among the relationships prone to this. Suspect deals include below-cost prices and prices under what the supplier charges other customers of similar volume who bring no federal referrals. OIG’s ambulance supplier guidance from 2003 raises the same concern about hospitals and nursing homes that buy ambulance services for private-pay and Part A patients while referring Part B and Medicaid patients. Its rule of thumb: charge fair market value in an arm’s-length deal that does not depend on how many referrals come with it, and document how you arrived at the price.

Decide who can book and what makes a ride billable

Disputes are easier to prevent at booking than to settle at billing. Put these rules in the agreement:

• Who may request rides. A list of roles or names, such as case managers, the scheduling desk, and the charge nurse on nights.
• What each request must include. Rider name, pickup address, destination, appointment time, service level, and who is asking.
• Purchase orders or authorization numbers, if the facility uses them. Put the number on every invoice line it covers.
• Standing orders for repeat appointments like thrice-weekly dialysis, with an end date.
• Changes and cancellations, how they are sent and how much notice avoids a fee.

A ride is billable to the facility when an authorized person requested it, the rider falls within the agreement, and the trip was completed or ended as a no-show under the written policy. Keep the booking record with the trip. It is the first thing you will need in a dispute.

What every invoice should show

An invoice should let a clerk match each charge to a booking without phoning you. Federal agencies define a proper invoice in 5 CFR 1315.9: vendor name, invoice date, the contract number or other authorization, your invoice number, a description with price and quantity, payment terms, taxpayer ID, banking information, and a contact name and phone number. It is a good checklist for any facility.

Have vendor setup paperwork ready before the first payment. A Form W-9 gives your taxpayer identification number to a payer that must file information returns, and a current certificate of insurance answers the next question.

Invoices name riders, dates, and destinations, so treat them as protected health information. The HIPAA Privacy Rule lets a covered entity disclose information to get paid (45 CFR 164.506), and the minimum necessary standard in 45 CFR 164.502(b) still applies to those disclosures. Give the facility enough to match the ride and nothing clinical. Send invoices through a secure link or portal rather than as open email attachments. The NEMT invoice template lays out these fields.

Monthly invoices, statements, and net terms

Choose a billing rhythm that matches how the facility pays:

• Monthly, one invoice per period, listing every leg. One document per period is the simplest thing for a facility’s accounts payable team to approve.
• Weekly, for high volume or a facility that pays slowly, so no single invoice grows large enough to stall.
• Per ride, for facilities that book only occasionally, such as a clinic that calls a few times a month.

A monthly statement is different from an invoice. It lists every open invoice with its age and the total balance, and it prompts payment without billing anything new. Send one each month to any facility with an unpaid balance.

Payment terms are whatever the signed agreement says, such as net 15 or net 30, counted from the invoice date. Print the terms and due date on every invoice. If you charge a late fee, set it out in the agreement with the rate and when it starts, and confirm your state’s limits with your attorney first.

Federal buyers work under the Prompt Payment rules at 5 CFR part 1315:

• Payment is due on the date the contract sets. When the contract is silent, the agency has 30 days from receiving a proper invoice.
• An agency that finds an invoice improper must return it within 7 days and list every defect.
• Late payments earn interest automatically, whether or not you ask. Treasury’s rate for July through December 2026 is 4.75 percent a year.
• VA contracts that carry the clause at 48 CFR 852.232-72 require electronic invoices through VA’s system or an X12 format. Email, fax, and scanned invoices do not qualify.

Unpaid invoices then move into your receivables routine. The accounts receivable guide covers aging and follow-up, and NEMT cash flow covers planning around slow payers.

Handling disputed trips

A facility dispute often concerns a line or two, not the whole invoice. Agree in advance that the facility pays the undisputed lines on time and flags the rest within a set number of days.

Answer each disputed line in writing within the time the agreement sets. Either confirm the charge with the records attached, or issue a credit memo that names the original invoice and line. Then look for patterns. If the same dispute keeps coming back, fix the booking step that causes it, such as requiring a requester name on every same-day order.

Billing facilities in HealthRide

Facility staff can book rides, watch the van approach, and open and pay their invoices from their own HealthRide portal. Each invoice gathers that facility’s completed trips for the period, priced from its rates, with the due date set from its payment terms, whether net 15, 30, or 60. Rider details are shown only to payers you approve, and a past-due list tells you which facilities to follow up with. See invoicing.
