The Trip Record That Survives a Medicaid Audit: Fields That Actually Matter

Ask a NEMT operator why a claim got denied and you'll rarely hear 'the trip didn't happen.' You'll hear 'the signature line was blank' or 'the times didn't match the GPS.' Brokers and state Medicaid agencies audit trip records, not intentions — and the record either has every field or it doesn't. Here's what a defensible trip record actually contains.

The fields auditors check

• Member identity — the rider's name and Medicaid/member ID matching the authorization, not just whoever got in the van
• Pickup and dropoff times — actual timestamps, ideally GPS-verified. Rounded 'about 9:15' entries are the first thing an auditor circles
• Pickup and dropoff addresses — the real locations, matching the authorized trip legs
• Driver and vehicle ID — which specific driver and which specific vehicle ran the trip, tied to your roster
• Member signature or documented refusal — the single most-denied field. A signature, or a note that the member refused/couldn't sign with a witness where required
• Trip status and outcome — completed, no-show, cancelled at door. 'No-show' with a timestamp and location is billable-adjacent documentation; an empty field is a write-off
• Odometer or mileage where your state/broker requires it — some brokers reimburse mileage-banded, so the number matters

Where paper and spreadsheets break

Every one of these fields fails the same way on paper: it gets filled in at the end of the shift, from memory, in the van. Times get rounded to the quarter hour — which is precisely what makes auditors suspicious, because real GPS timestamps never end in :00 or :15 for a whole day of trips. Signatures get skipped when the member is slow or the driver is behind. By Friday, nobody remembers whether trip 31 on Tuesday actually had a signature.

The fix isn't more diligence — it's capturing the record at the moment it happens. When the driver taps 'arrived,' 'picked up,' and 'dropped off' on their phone, the timestamp and GPS location write themselves. The signature is captured on the driver's screen before the trip can be closed. There's nothing to reconstruct at 6pm, which is the whole point.

Retention: keep it longer than you think

Most brokers and state programs expect trip records retained for five to seven years — check your broker contract and state Medicaid manual for the exact figure, because it varies. That's a long time for a filing cabinet. Digital records with a search bar mean an audit request for 'all trips for member X in March' is a filter, not a weekend.

The audit you don't see coming

The best time to fix trip documentation is before a broker asks for it. Operators who run clean per-trip records don't just survive audits — they win contracts on them, because on-time rate and documentation quality are the two numbers brokers actually score. In PRIME, every trip a driver runs produces this record automatically: GPS-stamped arrival/pickup/dropoff, member signature on the driver's screen, driver and vehicle tied to the job. Export for a broker audit is a filter and a download, not a paperwork project.
