Vertical integration is reshaping the healthcare landscape as insurers, PBMs, pharmacies, and providers increasingly operate within the same corporate structures. With most prescriptions processed by a limited number of PBMs, consolidation can introduce new patient access barriers. This episode examines the scale of vertical integration and outlines its implications for prescription access across retail and specialty therapies.

Using oral oncology and SGLT-2 therapies as examples, this episode explores approval gaps and pharmacy switching patterns.
