Beginning with service dates on and after January 1, 2011, the Centers for Medicare & Medicaid Services (CMS) requires that electronic claims for ambulance services report mileage to the nearest tenth of a mile when the trip is less than 100 miles.

Wellmark can process claims using whole numbers only.

Ambulance claims reported with a fraction of a mile that we receive for Wellmark or MedicareBlue^SM PPO members will be rounded up to the nearest whole number.
