Medicare Claims Processing Manual (Pub. 100-04), Ch. 4 § 20.6.9
Modifier FB
20.6.9 - Modifier FB
(Rev. 11937; Issued: 03-31-23; Effective: 04-01-23; Implementation: 04-03-23)
FB: Item provided without cost to provider, supplier, or practitioner, or full credit
received for replaced device (examples, but not limited to, covered under warranty,
replaced due to defect, free samples)
From 2007 through 2013, HOPDs were required to report modifier FB when appropriate.
As discussed in the CY 2007 OPPS final rule (71 FR 68076 through 68077), effective for
services furnished on or after January 1, 2007, Medicare reduced the amount of payment
for certain APCs when the hospital reported that it received a listed device without cost
or where the hospital received a full credit for the cost of a replaced listed device. The
reduction applied only when specific devices were replaced. To indicate that the hospital
received the device without cost, modifier FB must have been reported.
In addition, OPPS hospitals were required to report modifier FB on the same line as the
surgical or procedure code (not the HCPCS Level II device code) for a service that
required a device for which neither the hospital, nor the beneficiary, was liable to the
manufacturer. Similarly, hospitals were required to report modifier FB on the same line
as the surgical or procedure code (not the device code) for a service that required a device
when the manufacturer gave credit for a device that was replaced with a more costly
device. Refer to section 61.3 of this manual for instructions regarding charges for items
billed with the FB modifier.
As of January 1, 2014, modifier FB is no longer required on OPPS claims, and has been
replaced with value code FD (credit received from the manufacturer for a replaced
medical device) as discussed in the CY 2014 OPPS/ASC final rule (78 FR 75006 through
75007), as well as in section 61.3.6 of this manual. Specifically, effective January 1,
2014, HOPDs are no longer required to report modifier FB, and instead, must report
value code FD to indicate the amount of the credit in the amount portion for value code
FD when the hospital receives a credit for a replaced device that is 50 percent or greater
than the cost of the device. For more information on value code FD, refer to MLN
Factsheet MLN909368 dated May 2022, which is available on the cms.gov website,
specifically, at https://www.cms.gov/Outreach-and-Education/Medicare-Learning-
Network-MLN/MLNProducts/Downloads/cardiacdevicecredits-ICN909368.pdf
Although no longer required for OPPS claims, modifier FB is still required on ASC
claims.
