Medical Programs

ESIS Medical ImpactSM has a significant impact on the outcome of workers compensation claims. Our outcomes-based model is comprehensive and built on ESIS’ philosophy that collaborative and consistent management is a key to success. Our best practices are developed to support this philosophy and ensure we provide high quality, cost-effective medical and vocational services to our clients.

We are an outcomes driven, customized, medical cost containment program fully integrated in our claims model, providing oversight on quality medical care, reduction of costs through negotiated preferred provider rates, and coordination with all parties to return the injured/ill worker to suitable, gainful employment.

The key to successful medical management begins before the injury occurs.  We work in partnership with our clients, prior to injuries, to identify local preferred providers, ensure medical panel cards are posted, and transitional work assignments are created in the event employees need alternate temporary positions. 

When it comes to workers compensation medical care management, ESIS Medical Impact stands apart from competitors thanks to the integration of extensive case management resources with our broad range of client claims management services. Every component of medical care – pharmacy benefit management, bill review services, triage nursing services, preferred provider network and more is integrated into our program design behind the scenes to produce superior quality of care and cost outcomes.

Client benefits include:

  • High quality and appropriate medical care
  • Timely and appropriate sharing of claims and medical information
  • Reduced cost
  • Prompt payments
  • Timely and appropriate return to work

Overview of Medical Solutions:
The NurseLine provides access to Registered Nurses via a toll free telephone number whenever an injury occurs; this is available 24 hours a day, 7 days a week.  Via the NurseLine, nurses assess workers’ injuries and help them receive the appropriate treatment at the right time in the right settings to ensure faster return to work.

ESIS Triage
Upon meeting specific intake or mid-case triggers, the claim is electronically referred to an ESIS triage nurse to complete a brief review of the file activity, compare against clinical guidelines, and document a one time Medical Review Assessment to assist the adjuster in ensuring appropriate medical direction of the claim.

ESIS Nurse ImpactSM – Telephonic Case Management
Telephonic Case Management (TCM) is a criteria-based, telephonic early identification and assessment product involving a medical case management system.  Registered Nurses receive early notice of work injury and facilitate appropriate medical care and return to work through direct provider, employer, employee, and claim adjuster communications.  If appropriate, this includes channeling the injured worker to a Preferred Provider facility for treatment (ExPO, Panel or PPO). If hospitalization services are warranted, the TCM nurse will conduct the pre-admission/continued stay review services at no additional charge.

ESIS Nurse ImpactSM - Field Case Management
Medical Field Case Management Services are provided by Registered Nurses dedicated to ESIS. The nurse assigned to a particular file works closely with the employer, physician, claim representative, and injured worker.  The objective is to assist in reducing disability, to insure that appropriate medical services are offered and implemented, and to facilitate return to work.  This service ultimately reduces claim costs. 

Utilization Review:

Utilization Review evaluates the medical necessity, appropriateness of setting, efficacy, or quality of care for services, treatments, procedures and supplies.  Often, a prior approval is required before a patient can be hospitalized, receive expensive tests or procedures, or be referred to a specialist or specialists. Utilization Review is an important tool. It not only helps avoid costly or unnecessary treatments, but also helps prevent inappropriate treatments that put patients at risk.  Additionally, Utilization Review is used to ensure that injured workers get needed care based on guidelines developed using clinical evidence based medicine.

ESIS Pharmacy ImpactSM

ESIS’ Pharmacy Impact is a comprehensive solution designed to: 

Bill Review:

As a first step, bill review performs automated comparisons of provider bills to verify that charges fall within state mandated fee schedule guidelines, or within usual and customary charges (applied in states mandating fair and reasonable charges without setting fee schedules). Numerous other components of bill review include data integrity checks, auto indexing to ensure bills are matched to the correct claim, clinical edits, application of negotiated network discounts, and numerous other bill review functions. These services are performed by coding specialists, auditors and nurses to maximize outcomes. 

Preferred Provider Organizations (PPO)
ESIS’ Workers Compensation Preferred Provider Organizations is a mosaic integrated network based upon our  selection of the most comprehensive provider groups at the state level. The broad based network allows for complete coverage with more than one million hospitals, industrial clinics, physicians, chiropractors, dentists, physical therapists, radiologists, home health care agencies, pharmacy and ancillary service providers.

ESIS ExPO® Exclusive Network
ESIS ExPO is an outcome-based provider selection tool. We have created a hierarchy of providers who have demonstrated outstanding results over a range of ESIS-identified criteria. ESIS developed its criteria after reviewing in excess of five million bills against ultimate claim costs to compare performance of treating physicians against the population. More than 11 distinctive performance metrics were identified and provider outcomes are measured on a total cost per claim basis.

Special Investigations Unit

A critical component of workers compensation and liability claims management and cost containment is the identification of fraudulent claim activities. ESIS’ Special Investigation Unit (SIU) understands that exaggerated or false claims are both difficult and time consuming to deal with. That’s why we have established a dedicated unit to work on behalf of our clients to help or reduce the incidence of fraud.

Our SIU team is comprised of highly experienced specialists that have law enforcement and/or claim investigation backgrounds.

ESIS is proud to partner with our SIU vendor partners, ICS Merrill, Global Options, G4S Compliance and Investigations, and HUB Enterprises who provide ESIS clients with unique advantages by offering greater flexibility and selection of investigation firms at competitive rates.
