"If you remove your legacy numbers from the 'Other Provider Identifier/Other Provider Identifier Type Code' fields, linkages that Medicare has established using the reported Medicare legacy numbers will be broken and your Medicare claims could be rejected," CMS warns in a message to providers.
The old problem:
