With the demise of the Chevron principal, courts are even more likely to use jurisprudence in isolated ways, when deciding cases. For example, a July 2024 case ruled against the HHS decision to include "transgender" in "sex discrimination" by using a 1972 dictionary.

How "Hobby Distillers" and "Medicare Law" Intersect
Cases involving Medicare law may hinge the the 1965 Medicare statute, with the foundational terms, "reasonable and necessary" (in regard to health services and its technology).
Here's a touchpoint. In the new case HOBBY DISTILLERS, a Texas federal court has ruled against an old law prohibiting home distillers (moonshine). The court found no justification for the federal power in the tax authority, the interstate commerce authority, nor in the fallback authorities to make laws "necessary and proper" for granted purposes.
Here's the Reuters article and a link to the 32 page decision.

What is "NECESSARY"?
Medicare law hings on "reasonable and necessary" while the Constitution has a major clause about "necessary and proper." In a 2023 law review article, Calabresi et al. dissect the dictionary definition of "necessary." (With dictionaries from the founding era.)

Clearly, the article is necessary reading.
For example, let's say there's a court case whether Medicare should cover PET Scans. Rather than the agency making a medical necessity decision, which is then followed by most courts ("Chevron"), we'd have a jurisprudential analysis of whether a PET scan fits the dictionary definition of "necessary." As the Supreme Court wrote in LOPER (ending Chevron), judges are trained to make such statutory interpretations, agency staff are not.

I. THE DRAFTING AND RATIFICATION OF THE NECESSARY AND PROPER CLAUSE
A. The New Learning
For many years, conventional wisdom held that the Necessary and Proper
Clause was "a masterpiece of enigmatic formulation,"(fn23)
such that "no one,including the constitutional framers, knows the
point of the phrase 'necessary and proper."' (fn24)
...A parade of distinguished scholars has lamented the lack of information
about the clause's origins.
