MSK Announcement

Musculoskeletal Management and Interventional Pain Management Program: Transition of Utilization Review to NIA Effective for Service Dates beginning January 1, 2024

All of us at Wellcare are committed to continuous improvement of quality services for our members. With that in mind, Wellcare has entered into an expanded partnership with National Imaging Associates, Inc. (NIA)1, to implement a new Musculoskeletal (MSK) Management program, to include Interventional spine Pain Management (IPM) services.

This MSK program includes prior authorization for non-emergent outpatient IPM services, and inpatient and outpatient hip, knee, shoulder, lumbar, and cervical spine surgeries for Wellcare Medicare members. The decision to implement this program is consistent with industry-wide efforts to ensure clinically appropriate quality of care and to manage the increasing utilization of these services. For complete CPT/HCPCS code listing, please see the Online Authorization Lookup Tool.

There will be no change to claim submission requirements or inpatient notification of facility admission and elective inpatient admission prior authorization requirements.

Under terms of the agreement between Wellcare and NIA:

  • Wellcare will oversee the MSK program and continue to be responsible for claims adjudication and medical policies.
  • NIA manages IPM services and inpatient and outpatient MSK surgeries through the existing contractual relationships with Wellcare.
