The A/B MAC (Part A) submits an ECRS request to the MSP Contractor when the following billing
situation occurs:
• Claim with primary insurer identification, no primary payer amounts, and nothing
indicated in remarks field;
• Beneficiary has a black lung CWF record, bill is submitted with a black lung CWF
record, and bill is submitted with a black lung diagnosis, but without the primary amount
shown or without an Medicare Summary Notice (MSN), or without remarks, which denies
the black lung claim;
• MSP claim filed with very low primary payment (investigate for possible keying error
with provider to ensure accurate payment amount) (Note: A/B MACs and DME MACs
A/B MACs and DME MACs must set the threshold that constitutes a very low primary
payment amount. A/B MACs and DME MACs must evaluate this threshold amount on
an annual basis);
• Diagnosis code, no MSP record, and claim does not show occurrence code 05 and
date nor remarks;
• Retirement dates same as dates of service (i.e., improper use of occurrence codes
18 and 19);
• Occurrence codes 01-04 used, but not MSP claim. No occurrence code 24 or remarks;
and
• No value code and zero dollars showing request for conditional payment.
