CMS Pub. 100-04, ch. 6, § 110.4.1
Annual Update Process
Barring any delay in the Medicare Physician Fee Schedule, CMS will provide the new
code files to CWF by November 1. Should this date change, CWF will be notified
through the appropriate mechanism. All future updates will be submitted via a Recurring
Update Notification form. These Recurring Update Notifications also describe how the
changes will be implemented.
CWF will be provided with 4 coding files (Physician Services, Professional Component
of Physician Services to be Submitted with the 26 Modifier, Ambulance, and Therapy)
that are effective based on dates of service January 1 through December 31 for that year.
New files shall be provided for each calendar year. Quarterly updates to the four files
will continue as usual.
A/B MACs (B)/DME MACs must continue to respond to rejects and unsolicited
responses received from CWF per current methodology.
A/B MACs (B)/DME MACs must reopen and reprocess any claims brought to their
attention for services that prior to this update were mistakenly considered to be subject to
consolidated billing and therefore, not separately payable. A/B MACs (B)/DME MACs
need not search claims history to identify these claims.
Prior to January 1 of each year, new codes files will be posted to the CMS Web site at.
https://www.cms.gov/Medicare/Billing/SNFConsolidatedBilling/. Should this date
change, A/B MACs (B)/DME MACs will be notified through the appropriate mechanism.
Coding changes throughout the year may also be made as necessary through a quarterly
update process.
As soon as the new code files are posted to the CMS Web site, through their Web sites
and list serves, A/B MACs (B)/DME MACs must notify physician, non-physician
practitioners, and suppliers of the availability of the files.

Unofficial copy of government-published law, reproduced from official sources with full provenance. Not an official publication; verify against official sources before relying on it in a filing. Records in the 'guidance' corpus, and only that corpus, are sub-regulatory (interpretive guidelines, survey procedures) and are not binding law. Validity bounds follow each jurisdiction's declared temporalBasis.
