Gulf Oil Spill Claims: Use CS and BP
Effective Jan. 3, 2011, all items and services related in whole or in part to an illness, injury, or condition associated with the 2010 oil spill in the Gulf of Mexico should be reported as such on Medicare claims. A new modifier and condition code were created for just this purpose.
Medicare fee-for-service claims from physicians, other practitioners, and suppliers should be annotated with the modifier CS Item or service related, in whole or in part, to an illness, injury, or condition that was caused by or exacerbated by the effects, direct or indirect, of the 2010 oil spill in the Gulf of Mexico, including but not limited to subsequent clean-up activities for each line item where the item or service is related.
Claims from institutional billers must be annotated with condition code BP Gulf oil spill related when the entire claim is so related or with modifier CS for each relevant line item when only certain line items are so related.
The new modifier and condition code are to be used for claims with dates of service on or after April 20, 2010.
The Centers for Medicare & Medicaid Services (CMS) is requesting providers, physicians, and suppliers who submitted claims for services related to the Gulf oil spill prior to the creation of the new modifier and condition code contact their Medicare contractor. Assistance is needed to identify previously processed claims related to the Gulf oil spill.
