If the Medicare payment amount is zero, this figure must also be zero; • The "Cost Report Days" field of the CWF record contain zero days; • The "Value Code" field in the value data portion of the CWF record contains the appropriate value code to identify the primary payer. (See Pub. 100- 04, Medicare Claims Processing Manual, Chapter 25, §70 and 75, Field Locators 39-41, for appropriate value codes.); • The "Value Amount" field in the value data portion of the CWF record contains the amount Medicare would have paid in the absence of the primary payer's payment. (The A/B MAC (Part A) does NOT record this amount on the PS&R.); • The A/B MAC (Part A) does not record days or charges on the PS&R; and, • The A/B MAC (Part A) submits the bill to CMS in accordance with CWF documentation. The CMS uses data reported in the blood deductible and inpatient deductible items to update deductibles. (This data is not used for the PS&R.)
