Modifications to the National Coordination of Benefits Agreement (COBA) Crossover Process
The purpose of this instruction is four-fold: 1) to suppress claims that are fully denied due to Health Insurance Claim Number (HICN) and beneficiary name mismatch from the COBA crossover process; 2) to change the shared systems to ensure that they will not generate provider notification letters when the Coordination of Benefits Contractor (COBC) generates specified "222" and "333" error codes to Medicare contractors via returned Detailed Error Reports; 3) to clarify previous instruction concerning crossover messages on provider remittance advices as well as conditions under which
policy number information is derived from the incoming claim; and 4) to modify data population routines for outbound crossover files within the Part B shared system.
