Linda Heitman

Submitter Assigned Keywords

Referring Provider


The Referring Provider Identification in the NM108/NM109 is "Required if
Employer's identification/Social Security number (Tax ID) or National
Provider Identifier is known."

After the compliance date of the NPI, the NPI will be required in this
NM108/NM109 if known by the submitter. If the submitter does not know
the referring provider's NPI (either referring provider does not have an
NPI, or the submitter does not know the NPI), then tax ID must be sent
if known. If the submitter does not know either a NPI or a tax ID, then
another type of identifier is required in the Referring Provider
Secondary Identification REF segment.
