MAS (Medical Answering Services) NY Portal Guide for Providers
DRT Pros Operations Library · Updated October 2026
In New York, many Medicaid transportation trips reach providers through Medical Answering Services (MAS), the broker that contracts with NEMT fleets across the state and runs one of the busiest provider portals in the market. Providers that operate the MAS portal well get more trips, fewer denials, and better scorecards.

Trip types and booking in the MAS portal
MAS handles scheduled trips (dialysis, chemo, clinic appointments), same-day and urgent trips, and will-call returns. Scheduled manifests arrive in bulk; same-day requests require fast portal response because unclaimed trips move to other fleets quickly.
- Accept or decline same-day requests within the portal response window
- Verify member Medicaid ID, trip authorization, and facility details before dispatch
Documentation and delivery confirmation
NY programs emphasize trip logs: pickup and drop-off times, missed trip reasons, and mileage. Driver reports must reach the portal the same day the shift ends.
- Complete portal trip statuses at end of every shift
- Flag facility access issues and long wait times at clinics with notes
Billing and denial patterns
MAS billing ties to confirmed trips and authorization codes. Frequent denial causes include missing trip documentation, billing outside submission windows, rate mismatches, and services rendered without prior authorization.
- Batch review before submission: authorization, rate code, delivery status
- Track submission deadlines per program; NY windows move quickly
