Why Medicare cross over not happening automatically – some basic reason to check.
Medicare/MO HealthNet (crossover) claims that do not automatically cross from Medicare to MO HealthNet must be filed through the MO HealthNet billing Web site, www.emomed.com or through the 837 electronic claims transaction. It is advised providers wait sixty (60) days from the date of Medicare’s explanation of benefits (EOMB) showing payment before filing an electronic claim. This will avoid possible duplicate payments from MO HealthNet.
Claims may not cross over from Medicare to MO HealthNet for various reasons. Two of the most common reasons are as follows:
• Invalid participant information on file causes many claims to not cross over electronically from Medicare. Participants not going by the same name with Medicare as they do with MO HealthNet will not cross over electronically. Additionally, the participant’s Medicare Health Insurance Claim number (HIC) in the MO HealthNet eligibility file must match the HIC number used by the provider to submit to Medicare. It is the responsibility of the participant to keep this information updated with their Family Support Division Eligibility Specialist.
• MO HealthNet enrolled providers who have not provided their National Provider Identifier (NPI) used to bill Medicare to the Missouri Medicaid Audit Compliance (MMAC), Provider Enrollment Section, also causes claims to not cross over electronically from Medicare. Providers in doubt as to what NPI is on file should contact Provider Enrollment by e-mail at mmac.providerenrollment@dss.mo.gov.
Providers who have not submitted their Medicare NPI may fax a copy of their Medicare approval letter showing their NPI, provider name and address to Provider Enrollment at 573-526-2054.
