MO HealthNet OPRA Provider NPI and Enrollment Requirements: Warning Phase Ends November 1, 2019

October 18, 2019

By: Brooke Bennett Aziere and Amanda M. Wilwert


On October 17, 2019, MO HealthNet announced the end of its warning phase. Effective for dates of service on or after November 1, 2019, all claims submitted to MO HealthNet are required to include the National Provider Identifier (“NPI”) number of the Ordering, Prescribing, Referring, or Attending (“OPRA”) physician or other professional. In addition, all OPRA practitioners must be individually enrolled as a MO HealthNet provider. MO HealthNet will deny claims missing this information starting on November 1, 2019.

MO HealthNet implemented this policy to comply with state and federal regulations, which provide that state Medicaid agencies must require all claims for payment for items and services that were ordered, prescribed, or referred to contain the NPI of the OPRA practitioner, and that all OPRA practitioners must be enrolled as participating providers in the state Medicaid program. These requirements apply to hospitals, mental health hospitals, state institution long-term care facilities, nursing homes, private home-ICF/IDs, home health agencies, rural health clinics, and hospices.

MO HealthNet has gradually implemented this policy since November 1, 2017, giving impacted providers two (2) years to become compliant. Since October 14, 2018, MO HealthNet has sent providers a warning message on claims that did not contain the OPRA practitioner’s NPI or if the OPRA practitioner was not enrolled with MO HealthNet. The warning message appeared on the providers’ remittance advice and stated, “Attending physician provider/license number missing.” Despite these warnings, providers continue to submit claims without the necessary NPIs and for practitioners who are not enrolled with MO HealthNet. 

Further, for claims that do not require submission of the OPRA practitioner’s NPI, but a provider chooses to submit one anyway, MO HealthNet will deny the claim if the OPRA practitioner is not actively enrolled as a MO HealthNet provider. 

Providers need to act now to make sure all NPIs for ordering, prescribing, referring, or attending practitioners are accurately reported on all claim forms. Additionally, providers must ensure that its practitioners are appropriately enrolled in MO HealthNet before the practitioners order, prescribe, or refer for any service payable under the state Medicaid program.
