We also secured regulatory approval from the California Department of Managed Health Care.

In doing so, Raja leads privileged audits, investigations, policy formation and, when necessary, self-disclosures to government agencies.

Specialty Pharmacy. Secured a stay of the suspension of Medicaid program payments to a specialty pharmacy that dispenses and distributes HIV/AIDS medication to vulnerable and low-income populations. The pharmacy had received a notice of payment and provider-number suspension. If permitted to proceed, the suspension would have caused immediate hardship and care interruptions for hundreds of Medicaid beneficiaries. Before it went into effect, the Medicaid agency indefinitely stayed the suspension after we advocated for a stay and demonstrated the devastating effect it would have on vulnerable populations. The resulting stay represented a successful outcome for both the client and the Medicaid beneficiaries it serves.
