Innovative Management Systems’ Contracting Department serves an integral role in network management.

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).

Utilization Management

Utilization management or utilization review is the use of managed care requirements for prior authorizations and hospital clinical review, which will allow payers, particularly health insurance companies, to manage the cost of health care benefits by assessing the appropriateness of the benefits against evidence-based guidelines/criteria before they are provided.

IPAs managed by Innovative Management Systems (“IMS”) will NOT be financially responsible for any services conducted without prior authorization approval.

Providers can request prior authorization through the provider portal, which can be accessed through this link: If you do not yet have a portal account, please call IMS MSO at 323-800-8283 to obtain a copy of the Authorization Request Form and for further assistance. If you are submitting using the Authorization Request Form, please fax the form and clinical notes to the IMS UM Department at 323-798-3031.

Authorization does not guarantee payment. Patient must be eligible with the respective IPA on the date of service. Authorizations are valid for 90 days based on patient’s eligibility status. It is the responsibility of the provider to verify patient’s eligibility prior to providing services.

Post-stabilization care services that are administered if the hospital fails to call IMS to request pre-approval of post-stabilization care services and fails to wait 1 hour for pre-approval/authorization after the request. “Post-stabilization care services” are covered services that are related to an emergency medical condition provided after an enrollee is stabilized, and provided to maintain the stabilized condition, or under certain circumstances, to improve or resolve the enrollee’s condition.
All IPAs managed by Innovative Management Systems follow all federal Medicare regulations regarding assuming financially responsible for post-stabilization care services obtained within or outside the IPA network.

Submission of an inpatient notification is required for inpatient admission within 24 hours upon pre-approved admission. Please include the Face sheet along with any other supporting clinical documentation where applicable.
