Modifier 51
Multiple procedures
—Modifier 51 is used anytime there
are multiple procedures identified in the same surgical ses-
sion. It should never be appended on an add-on code where
another code must be reported with the primary procedure
(example, +11101), and it is not appended on codes identi-
fied as modifier 51 exempt (example, 31500). For all other
procedure codes, if more than one procedure is performed,
it is appropriate on all procedures but the primary. If a
patient has been injured and has fractures of both the
clavicle and the sternum and both are treated with a closed
reduction, modifier 51 should be added to the second pro-
cedure.

Modifier 51 is attached to the procedure of ‘lesser value’
based on the relative value units, and on multiple proce-
dure reduction rules. Payment will be 100 percent of the
first procedure and 50 percent of each additional proce-
dure. Be sure to indicate the procedure of the lesser value
to be the one in which payment is reduced.
Critical to Note:
Many payers no longer require this
modifier, including the CMS. Some payers will even deny
claims if the modifier is utilized. If your payers deny pay-
ment or do not want this modifier reported, it should not
be submitted. For example: Palmetto GBA strongly recom-
mends that this modifier not be reported.
