Effective August 1, 2013, we are expanding the ZIP code requirement for 
ambulance service claims. In the September 2012 edition of 
Partners in 
Health UpdateSM, we informed you of the ZIP code requirement for 
Medicare Advantage PPO ambulance service claims. We are expanding this 
requirement so that ambulance providers will be required to include ZIP code 
information on all ambulance service claims submissions, both commercial and 
Medicare Advantage.
[
]Billing guidelines[
]
Please use the following guidelines based on how you submit claims for 
ambulance services:
Electronic claims. If you bill electronically via HIPAA 5010, please include 
both the pick-up and drop-off ZIP codes in the appropriate fields.
Paper claims. If you bill claims on paper, please include the pick-up ZIP code 
in box 23 of the CMS-1500 form. The ZIP code is the only data element that 
should be included in that field. 
Please contact your Network Coordinator if you have any questions about this 
requirement.
