AmeriHealth Caritas, one of the nation’s largest Medicaid insurers, has announced the closure of its in-house pharmacy benefits manager, PerformRx, by the end of this year. The Newtown Square, Pennsylvania-based company shared the news with employees, citing shifting market conditions and a rapidly evolving regulatory landscape as key drivers behind the decision.
What Is PerformRx and Why It Matters
PerformRx was established by AmeriHealth Caritas in 1999 and has since grown to hold contracts across 13 states, including Pennsylvania and Delaware. Pharmacy benefit managers (PBMs) serve as critical intermediaries in the healthcare system, helping health insurers manage and administer prescription drug benefits on behalf of millions of members. Over the past decade, PBMs have become increasingly influential players in the healthcare industry, often determining which medications are covered, at what price, and through which pharmacies.
The closure of PerformRx marks a significant strategic shift for AmeriHealth Caritas, which has historically maintained an in-house PBM to serve its large Medicaid membership base. With operations now being transitioned to a third-party provider, the company is joining a growing trend of insurers consolidating their pharmacy benefit operations with larger, specialized PBM entities.
OptumRx to Take Over PBM Services
Beginning January 1, OptumRx — a subsidiary of UnitedHealth Group Inc. and one of the three largest PBMs in the United States — will assume responsibility for managing pharmacy benefits previously handled by PerformRx. OptumRx is not a new partner for the broader Independence Health Group family. The company already provides PBM services to Independence Health Group, which is the majority owner of AmeriHealth Caritas and is best known for its Independence Blue Cross health insurance business.
Independence Health Group holds a 61.3% ownership stake in AmeriHealth Caritas, while Blue Cross Blue Shield of Michigan owns the remaining share. The transition to OptumRx is expected to streamline pharmacy benefit operations and align AmeriHealth Caritas more closely with its parent organization’s existing infrastructure.
Regulatory Pressure Reshaping the PBM Industry
The announcement comes amid significant regulatory changes affecting pharmacy benefit managers nationwide. President Donald Trump recently signed new legislation introducing fresh restrictions on PBM practices, adding pressure on smaller and mid-size PBMs to consolidate or exit the market. These regulatory shifts are prompting insurers and PBM operators to reassess the viability of maintaining independent PBM operations.
One notable regulatory change directly impacting PBM operations is a new California law that took effect on January 1. The law prohibits PBMs from charging health plans — including Medicaid plans — more than what they pay to pharmacies for drugs, a practice known as “spread pricing.” PBMs are still permitted to charge a flat administrative fee in California, but the elimination of spread pricing significantly limits a key revenue stream for smaller PBMs operating in the state. PerformRx held contracts in California, making this law particularly relevant to the closure decision.
Employee Impact and Business Continuity
AmeriHealth Caritas emphasized that the decision to close PerformRx was not a reflection of the performance or dedication of PerformRx staff. “This decision reflects evolving market and regulatory landscape, not the performance or dedication of our PerformRx leadership or associates,” the company stated in its internal announcement.
In a statement to the press, AmeriHealth Caritas indicated that it expects a “limited impact on jobs, with many functions remaining in-house to support the same high-quality experience for members and providers.” The company did not provide specific figures on how many positions may be affected or relocated.
Leadership and Financial Context
AmeriHealth Caritas accounted for approximately three-quarters of Independence Health Group’s $32 billion in total revenue in 2024, underscoring its financial significance within the larger organization. The former CEO of AmeriHealth Caritas, Kelly A. Munson, recently succeeded Gregory E. Deavens as the top executive at Independence Health Group, adding a layer of internal leadership continuity during this transitional period.
As the PBM industry continues to face regulatory scrutiny and market consolidation, the closure of PerformRx signals a broader industry realignment — one that is pushing healthcare organizations to streamline operations and align with larger, more established pharmacy benefit partners.
