Prior authorization and referral updates
- PCP to in-network specialists - No referral is required.
- Changes have been made to the Prior Authorization Service List (XLSX), in accordance with LA Rev Stat § 46:460.54, effective for dates of service March 1, 2021 and after.
Medication requiring prior authorization
- Drugs requiring prior authorization or having any other restrictions are identified on the Louisiana Medicaid Single PDL (Fee For Service and Managed Care Organizations) (PDF).
- The LDH single PDL describes how medications are covered if the member were to receive them from an actual pharmacy. If the medication is normally administered by a health care professional and is reimbursed through “buy and bill,” then the prior authorization requirements listed in the printable and searchable formulary may not apply. If you have questions about drug coverage, please call 1-800-684-5502.
- Drugs administered by physician or outpatient hospitals on the Louisiana Medicaid Fee Schedule will be reimbursed. Use the Prior authorization lookup tool above to see if a code requires authorization.
Services requiring prior authorization
*Prior authorization for CT scans, MRIs/MRAs, nuclear cardiology services and other radiology codes is required for outpatient services only. Please use the Prior authorization lookup tool above to see if a code requires authorization. The ordering provider is responsible for obtaining a prior authorization number for the study requested.
Patient symptoms, past clinical history, and prior treatment information will be requested and should be available at the time of the call. (Outpatient studies ordered after normal business hours or on weekends should be conducted by the ordering facility, as requested by the ordering provider.
