HI 00910.010 Restriction on Providing Claim Numbers
Claim numbers will be provided if the information is needed for Medicare purposes. Any request for a claim number from a provider, physician, supplier, intermediary, or carrier (including such employees as nurses and office personnel) will be assumed to be for a Medicare program purpose if there is reason to believe this is the purpose and there is no evidence to the contrary.
Claim numbers will not be supplied to organizations providing billing and collection services for physicians. This position is taken because SSA is not assured that such organizations will maintain the confidentiality of the information, nor does SSA know the relationship which exists between physicians and these billing organizations.
