Top 10 Best Pharmacy Benefit Consulting Services of 2026

Gallagher supports PBM contract review and PBM strategy work that frames measurable decisions for formulary, network structure, and payment mechanics. Engagements typically include structured analyses tied to RFP responses, bidder comparisons, and contract term interpretation that internal stakeholders can govern during the PBM lifecycle. This delivery model works best when a single accountable party must coordinate strategy inputs with contract language and stakeholder reporting.

A key tradeoff is that Gallagher’s consulting depth increases demand for client-provided pharmacy claims and eligibility data access because meaningful benchmarking and validation require complete inputs. The service is a strong usage situation when a plan is preparing an RFP, evaluating network and pricing proposals, and needs defensible rationale for governance decisions after award.

Aon fits teams that need PBM strategy and procurement assistance with documented work products, including RFP support and PBM contract review inputs that can be routed through legal and procurement workflows. The provider also supports pharmacy network analysis and ongoing claims and eligibility data interpretation used for program governance. Strength shows in converting benefit and utilization policy questions into negotiation and oversight requirements that multiple internal stakeholders can review.

A tradeoff is that the value depends on buyer-provided plan data access and on participation from pharmacy, finance, and compliance stakeholders to validate assumptions. A common fit is an organization running a PBM refresh or vendor renegotiation where contract language and pricing mechanics drive measurable total cost of care outcomes.

Lockton’s PBM consulting engagements typically run through procurement and oversight workflows that include PBM contract review, performance expectation definition, and pharmacy network analysis to inform negotiation positions.

Teams get concrete outputs like issue logs, requirement matrices for solicitation, and clause-level notes that tie operational pain points to contractual remedies.

A key tradeoff is that the approach is documentation heavy and requires internal participation from pharmacy, finance, and compliance stakeholders to convert findings into governance actions. Lockton fits best when a sponsor needs structured PBM contracting support and ongoing oversight controls for formulary and network outcomes, rather than only ad hoc pricing comparisons.
