Services by Primary Diagnosis

Individuals with developmental disabilities may have multiple diagnoses. For example, an individual with a primary diagnosis of intellectual disability may also have a secondary diagnosis of epilepsy. This data solely captures the primary diagnosis.

The primary diagnosis is identified for individuals during the determination of eligibility for Medicaid services. While additional or co-occurring conditions may be identified, the primary diagnosis is required and can be accurately reported.

Individuals identified as having an “unknown/unidentified” primary diagnosis visited an Article 16 clinic to determine whether a developmental disability diagnosis was present.

Payments by Funding Category

Payments are made to providers for the delivery of OPWDD Medicaid services in two ways: (1) on a fee-for-service (FFS) basis; or (2) through a managed care arrangement.  Under a FFS model, a separate payment is made for each service delivered to a person.  For managed care, a set monthly fee, or capitation payment, is paid to an insurance company that then manages care and pays service providers. The Fully Integrated Duals Advantage (FIDA) demonstration program provides comprehensive medical, behavioral health and long-term supports and services to dually Medicare and Medicaid eligible individuals with intellectual and developmental disabilities (IDD) in a managed care service delivery model.
