National review of Medicaid opioid prescribing not yet feasible

The Office of Inspector General (OIG) has determined that limitations of the national Medicaid claims database, the Transformed Medicaid Statistical Information System (T-MSIS), makes a national review of opioid prescribing in Medicaid unfeasible. The system cannot yet identify all at-risk beneficiaries and providers, the OIG reported (OIG Report, No. OEI-05-18-00480, August 2019).

The OIG assessed the completeness of variables necessary to identify beneficiaries at risk of opioid misuse or overdose and the National Provider Identifiers (NPIs) of providers that ordered and dispensed opioids. According to the report, states were missing data necessary for a national review. Some states did not require NPI to be collected. Others included NPI in their data but incorrectly submitted the data or were unable to transmit the data to T-MSIS because of outdated systems. Without a provider NPI, it is not possible to identify all providers who may be overprescribing opioids and take appropriate action, or to identify providers for investigations of fraud, waste, or abuse, the OIG found.

Identification of beneficiaries can be impeded because a Medicaid beneficiary can have multiple IDs within a state or across states. If a beneficiary does have multiple IDs, prescriptions dispensed to the IDs would appear to be for multiple persons rather than one person. The OIG noted in the report that without a unique beneficiary ID, it is not possible to identify all at-risk beneficiaries in need of opioid-related treatment and conduct proper monitoring of services to protect beneficiaries from inadequate coordinated care.

States also have failed to report diagnoses codes for all services despite being required to do so. Without a diagnosis code, it is not possible to exclude all patients with cancer diagnoses for whom higher doses of opioids may be appropriate or to identify patients’ medical conditions to determine medical necessity for services.

The OIG noted in the report that in August 2018, CMS that all states were submitting T-MSIS data and that CMS was prioritizing T-MSIS data quality. According to the OIG, CMS indicated it would have research files available in 2019. CMS currently has been working with states to improve the quality of data submissions.

Recommendations

The OIG recommended that CMS strive to ensure that individual beneficiaries can be identified at a national level using T-MSIS. CMS should address instances in which a single beneficiary has more than one Medicaid ID within a state. CMS also should prioritize state reporting of prescriber NPIs and issue guidance to clarify the requirements for diagnosis codes.
