Participant Lock-In
MMAC is responsible for reviewing participants who may be subjecting the Medicaid program to fraud, waste and abuse. This includes a review of a variety of factors which include:
- The number of physicians prescribing services to a particular participant;
- The number of pharmacies used to obtain prescriptions;
- The frequency of refills or overlapping prescriptions;
- The number of emergency room visits, and
- The services received.
If a MO HealthNet participant is found to be misutilizing MO HealthNet benefits, the individual can be restricted to a physician/clinic, pharmacy, or both in accordance with 13 CSR 65-3.010, and may also be referred to the appropriate authorities for possible healthcare fraud investigation and prosecution.
If you suspect a participant is abusing Missouri Medicaid, you may report the suspicion to mmac.lockin@dss.mo.gov. It is helpful if you can provide the MO HealthNet participant’s name, Medicaid DCN, address, date of birth and/or social security number, and a complete description of the complaint.
