Affirmation Statement

HMSO providers and staff make utilization decisions based only upon the appropriateness of care, service and existence of coverage.  We do not reward individuals who conduct utilization review for issuing denials of coverage for health care services. Financial incentives do not encourage decisions that result in under-utilization of services.
