IMS offers credentialing and re-credentialing for providers and facilities. The team conducts monthly monitoring of the network and maintains records to ensure all expiring documents remain current and up to date. IMS can assist with provider directories and work as the liaison between the payers and physician groups to ensure all changes to the network are updated within contracted time frames.

IMS works directly with CAQH, a NCQA accredited Credentialing Verification Organization and national self-attested Provider Database, housing one million completed records across the nation. If you are looking to build a network or join a network, utilizing CAQH can help expedite the process and save on administrative efforts. Most payers will accept the CAQH application in lieu of their Credentialing application. This means that participating Providers will never have to complete another Credentialing application again, reducing administrative burden.

Don’t have an account with CAQH? IMS will help you create one if you don’t have the time. Simply email our friendly Credentialing Specialists at to obtain assistance or visit CAQH to register your account. You can also re-attest to your existing account and/or provide IMS access to your account if global access wasn’t already provided.

The Credentialing Committee is a non-biased diverse group of Providers contracted with IPAs managed by IMS for peer review. The Credentialing Committee meets on a monthly and ‘as needed’ basis to review the completed files and to make appropriate recommendations to the Boards. IMS also provides continuous monitoring of all expirables and daily sanction monitoring.

Customer Service

IMS provides extensive training to our Customer Service team to equip them with the knowledge and tools needed to offer meaningful and positive member and provider experiences. Our team takes full advantage of each opportunity to speak to a provider, member, caregiver, or family member by using motivational interviewing techniques to better understand the reason for the call, and to successfully resolve issues on the spot. Our Customer Service application was strategically selected to offer additional information to our Customer Service representatives. This provides our team with a complete view of each caller, to assist in addressing the member or provider’s outstanding needs. Our Customer Service team will always go the extra mile for each call to ensure that every caller feels valued and important.

Our Customer Service team is equipped to provide the most up-to-date member information to our physicians who are calling about Eligibility. Our Customer Service team and online Provider Portal will offer Primary Care Physicians (PCP) real time eligibility lists and reports regarding Health Risk Assessments (HRAs).

Questions? Please call us at 323-800-8283 to speak with our Customer Service Representatives, Monday – Friday from 8:00 – 5:00 PM PT.

Utilization Management

Utilization Management Overview

Utilization management, or utilization review, involves managed care processes such as prior authorizations and clinical reviews. These are used by health insurance companies to control health care costs by verifying that the planned services meet evidence-based guidelines before they are provided.

Authorization Requirements

  • Innovative Management Systems (IMS): Services conducted without prior authorization approval will not be financially covered by IPAs managed by IMS.
  • Prior Authorization Process: Providers can request prior authorization through the provider portal. If you do not have access to the portal or in emergency cases, you may also submit your request using an Authorization Request Form. Please fax this form along with the clinical notes to the assigned IPA’s fax number. Refer to the table below for more details.

Important Notes on Authorization

  • Authorization does not ensure payment. The patient must be eligible with the IPA on the service date.
  • Authorizations are valid for 90 days, contingent on the patient’s eligibility.
  • Providers must verify the patient’s eligibility before providing services.

Post-Stabilization Care Services

  • If a hospital fails to contact IMS for pre-approval of post-stabilization care services within one hour of the request, coverage may not be provided. These services are necessary to maintain or improve a stabilized condition following an emergency.

Inpatient Admission

  • Notification of inpatient admission is required within 24 hours of pre-approved admission. Please include the Face sheet and any relevant clinical documentation.

All IPAs managed by Innovative Management Systems adhere to federal Medicare regulations regarding financial responsibility for post-stabilization care services, whether within or outside the IPA network.
