| 24g | Days or Units | M | Enter the number of units, services, or items provided. Note: Providers submitting claims for ambulance transport mileage reimbursement for more than one episode of transportation for a single recipient on the same date of service, and the same ambulance transport Procedure Code / Modifier combination applies to more than one episode of transportation, the episodes requiring the same Procedure Code / Modifier combination must be mulled on the same claim line indicating the total number of episodes provided in the Block 24G (Units). In instances of this nature it is important to document in the recipient’s file associated with these services the reason why it was necessary to bill the Procedure Code/Modifier combination for more than 1 unit. Billable mileage is paid beyond the first 20 loaded or unloaded miles of a round trip. Enter the number of miles of the round trip minus the first twenty miles (e.g., If the round trip was 100 miles, then enter 80 (miles) in block 24g). |
