As of March 1, Medicare fee-for-service claims must include an
national provider identifier (NPI) in the primary provider fields
on the claim (billing, pay-to provider, and rendering provider
fields). Claims will be rejected without it.
You may continue to submit NPI/legacy pairs in these fields or
submit only your NPI. The secondary provider fields (referring,
ordering, and supervising) may continue to include only your legacy
number, if you choose.
In addition, if you already bill using the NPI/legacy pair in
the primary provider fields and your claims are processing
correctly, now is a good time to submit to
TrailBlazer Health Enterprises
a small number of claims containing only the NPI in the primary
provider fields. This test will serve to ensure your claims will
successfully process when the NPI only is mandated on all
claims.
