RECONCILIATION OF STATE INVOICE (ROSI)
Form CMS-304
INSTRUCTIONS
Effective: July 1, 2021

The ROSI (Form CMS-304) is to be used only to respond to the state’s invoice for current quarter
utilization.
Labelers use the ROSI in the following instances:
•
•

When disputing invoiced units.
When the state invoice contains zero Unit Rebate Amounts (URAs).

Labelers must remit accurate rebate payments; therefore, the current URA must be applied to the
units being paid. Labelers use the ROSI to report the correct URA to the state within 30 days of
receiving the state’s current quarter invoice. In addition, labelers should send any pricing
corrections to CMS.
Labelers may submit the ROSI in hard copy form or electronically. However, if a state cannot
accept an electronic ROSI, we expect the labeler to submit it in a hard copy format.
The adjustment and dispute codes found in the Adjustment and Dispute Codes for CMS 304/304a
document are used for both the ROSI and the PQAS. We expect labelers to select at least one
adjustment or dispute code per NDC, and labelers may use several if necessary. Some codes may be
appropriate for either situation. In addition, some codes require supporting documentation; however,
supporting documentation can always be submitted, even for those instances where it is not
specifically mentioned.
