This Note examines the statutory landscape of mental health parity in the United States. The lens of this Note is through the mental illness of anorexia. Parity laws mandate analogous limitations between mental and physical illness. Therefore, because anorexia has many physical manifestations, it serves as a nice juxtaposition to physical illnesses. This Note will argue for broad interpretation of the Mental Health Parity and Addiction Equity Act (MHPAEA) through comparative analysis of counterpart statute, the California Mental Health Parity Act (CMHPA). It will explore how courts have interpreted the CMHPA broadly to suggest that the MHPAEA should be interpreted the same way.
