The Supreme Court disagreed, holding that the classification is not all health care providers who receive in-house referrals, but rather just physical therapists. And since the classification treats all PTs the same, the Court upheld it as constitutional. Justice Toal dissented:
The majority concludes that it would be inappropriate to hold that the legislature must treat all health care providers and allied health professionals as similarly situated for purposes of self-referral issues. I disagree. In my view, this is precisely the type of situation in which the legislature should treat all health care providers and allied health professionals as similarly situated. Unlike the majority, I would find that the classification has no reasonable relation to the types of variations and nuances of the medical profession which would necessitate a distinction between physical therapist and all other health care professionals. Although I would agree that the separate classification of physical therapists may be appropriate in other situations, I find it difficult to envision any aspect of physical therapy which is so different from other health care services that it warrants separate classification for self-referral purposes.
I was amicus curiae for a group of patients who wanted the statute struck down. Needless to say, I'm with Justice Toal on this one!
