Therapy Services (PT, OT, ST)

Effective March 1, 2019, physical medicine services (physical therapy, occupational therapy and speech therapy) will no longer be managed through a post-service review process for Louisiana Healthcare Connections.  Louisiana Healthcare Connections remains committed to ensuring that physical medicine services provided to our members are consistent with nationally recognized clinical guidelines.  Therefore, the utilization management of these services will be managed by National Imaging Associates, Inc. (NIA) through a prior authorization program.  All providers will be required to obtain prior authorization for Physical Medicine services. 

NIA Call Center will be available to submit requests for prior authorization for dates of service March 1, 2019, and beyond. Any services rendered on and after March 1, 2019, will require prior authorization.

There are two ways to submit prior authorization: Through NIA’s Website at, or by calling NIA at 1-866-326-6301.  When requesting an authorization, please provide the name, address and TIN of the facility that will be used for billing the services.  Payments will be denied for services performed without a necessary prior authorization, and the member cannot be balance-billed for such services.

You will be able to upload requested records on the NIA website or through the NIA fax number at 1-800-784-6864.  Medical necessity reviews are based on clinical guidelines which are available on the NIA website.
