Pharmacy Expert Witnesses

Litigation involving pharmacy typically arises in commercial disputes across the drug supply chain rather than in individual dispensing errors. Disputes commonly involve contract disagreements between pharmacy chains, wholesalers, and manufacturers over supply chain management and counterfeit drug prevention obligations, disputes between pharmacy benefit managers, insurers, and pharmacies over reimbursement and formulary practices, and unfair business practice claims tied to pharmacy chain competitive conduct. Health systems and pharmacy automation vendors also face contract disputes over whether dispensing and supply automation technology met the specifications represented in a purchase or licensing agreement. The central issue in these matters is typically whether a pharmacy business practice, supply chain relationship, or vendor technology met the professional, contractual, and regulatory standards governing the pharmacy industry.

Pharmacy experts help attorneys evaluate these disputes by applying professional pharmacy practice standards and supply chain industry knowledge to the underlying business records and contractual relationships at issue. Their analysis can determine whether a pharmacy's supply chain and counterfeit prevention practices met industry expectations, whether a pharmacy benefit manager's reimbursement and formulary practices were consistent with applicable contracts and regulations, and whether pharmacy automation or dispensing technology performed consistent with its represented specifications. This work supports liability and damages positions in supply chain, PBM, and vendor technology disputes, and it can substantiate or rebut claims involving unfair business practices in pharmacy operations.

Because pharmacy business disputes span supply chain management, PBM reimbursement practices, and pharmacy technology, matching an expert's specific pharmacy background to the dispute is essential. Round Table Group's pharmacy network includes practitioners with experience in supply chain management and counterfeit drug prevention, Medicaid and managed care pharmacy operations, and community and hospital pharmacy practice standards, several of whom belong to professional organizations such as the American Pharmacists Association. Round Table Group has completed more than 75,000 expert searches for litigators, and we apply that experience to connect counsel with pharmacy experts whose industry background fits the specific commercial dispute. Let us help you find the right pharmacy expert for your case by calling us at (202) 908-4500.

Kinds of Cases We Work On

Round Table Group helps our clients find a wide variety of Pharmacy expert witnesses for cases like:

01

Rebate Formula Dispute Splits PBM Client Base

A regional health plan sued its pharmacy benefit manager, alleging the PBM's rebate pass-through formula systematically understated the discounts owed on brand-name specialty drugs over a multi-year contract term. A pharmacy benefits expert reconstructed the claims data against the contract's rebate guarantee language and reran the reconciliation using the PBM's own adjudication records. The expert found that a subset of high-volume therapeutic classes had been excluded from the guarantee calculation in a way the contract didn't support, understating rebates owed by roughly a fifth. That finding anchored the health plan's damages model and drove a settlement before trial.
02

Compounding Facility Potency Failures Trigger Recall Suit

A specialty infusion provider sued its compounding pharmacy supplier after routine potency testing showed a batch of sterile injectable products fell well outside the labeled concentration range. A compounding pharmacy expert reviewed the facility's USP 797/800 environmental monitoring logs, batch records, and testing protocols. The expert identified a gap in the pharmacy's beyond-use-date validation process that allowed degraded product to ship for roughly six weeks before detection. The finding supported the provider's breach of warranty claim and led to an arbitration award covering the recall and replacement costs.
03

Wholesaler Allocation Cuts Spark Supply Chain Claim

A hospital system sued its primary pharmaceutical wholesaler for breach of a distribution agreement after the wholesaler imposed allocation limits on a widely used generic injectable during a supply shortage, forcing the hospital to source at a premium from secondary distributors. A pharmaceutical distribution expert analyzed the wholesaler's allocation methodology across its full customer base. The expert found the hospital had been allocated a share well below its historical purchasing baseline while comparable accounts were largely unaffected. That comparison undercut the wholesaler's shortage defense and pushed the case toward a negotiated settlement.
04

PSAO Network Fee Structure Draws Franchise Suit

A group of independent pharmacy owners sued their pharmacy services administrative organization, claiming undisclosed markups on network transaction fees violated the terms of their affiliation agreements. A pharmacy business operations expert examined the PSAO's fee schedules against the disclosures provided at onboarding and renewal. The expert found the effective fee load had climbed well beyond what the disclosed schedule implied over the affiliation period. That analysis became the centerpiece of the pharmacies' certification motion in the resulting class arbitration.
05

Automated Dispensing Cabinet Defect Blamed for Diversion Gap

A hospital pharmacy department sued the maker of its automated dispensing cabinets after an internal audit revealed a pattern of controlled substance discrepancies traced to a software flaw in the override logging function. A pharmacy informatics expert reviewed the system's audit trail architecture and compared it against the vendor's own design specifications. The expert found the override function had failed to log dispensing events under a specific sequence of user actions for more than a year before the flaw was patched. That finding shifted responsibility for the diversion gap toward the vendor and was central to the settlement reached shortly before trial.
06

Mail-Order Fulfillment Delays Breach Service Guarantees

A national employer group sued its mail-order pharmacy vendor for chronic failure to meet contractual turnaround guarantees on maintenance medication refills. A pharmacy operations expert reviewed the vendor's fulfillment center throughput data and staffing records across the claim period. The expert found that average turnaround had exceeded the guaranteed window in more than a third of orders during peak months, correlating directly with periods of understaffing at the vendor's primary facility. The finding supported the employer's liquidated damages claim and resulted in a mediated settlement.
07

Generic Substitution Dispute Pits Manufacturer Against Chain

A generic drug manufacturer sued a retail pharmacy chain, alleging the chain's substitution algorithm was systematically routing prescriptions to a competitor's product despite a therapeutic equivalence and pricing agreement between the parties. A pharmacy formulary systems expert examined the chain's point-of-sale substitution logic and transaction logs. The expert found the algorithm weighted a rebate variable in a way that overrode the equivalence flag the agreement required it to honor. That finding undercut the chain's claim that substitutions were clinically driven and led to a settlement restoring the manufacturer's volume.
08

340B Compliance Audit Ignites Contract Pharmacy Fight

A safety-net hospital sued a contract pharmacy vendor after a 340B program audit revealed a pattern of duplicate discount claims on prescriptions that should have been excluded under the program's eligibility rules. A 340B compliance expert reconstructed the claims eligibility logic the vendor's software applied against the hospital's covered patient roster. The expert found the vendor's system had misapplied the eligibility flag for a recurring category of specialty referrals, inflating the hospital's exposure to program repayment. That finding shifted liability toward the vendor and anchored the resulting settlement.
09

Claims Adjudication Software Glitch Costs Chain Reimbursements

A regional pharmacy chain sued its claims adjudication software provider after a system update caused a wave of improperly rejected third-party claims across multiple insurance plans. A pharmacy claims systems expert reviewed the adjudication engine's rule changes against the chain's historical acceptance rates. The expert found the update had introduced a coding conflict that caused valid claims for an entire drug category to reject automatically for roughly two months. That analysis quantified the chain's lost reimbursements and was central to the arbitration award in the chain's favor.
10

Specialty Pharmacy Accreditation Lapse Voids Payer Contract

A specialty pharmacy sued a health plan for wrongful termination of its network contract after the plan cited an accreditation lapse the pharmacy claimed was a paperwork delay, not a substantive compliance failure. A pharmacy accreditation and compliance expert reviewed the accrediting body's standards and the pharmacy's actual operational practices during the lapse period. The expert found the pharmacy had maintained substantive compliance with every clinical standard at issue throughout the gap. That finding undermined the health plan's stated rationale and led to reinstatement under a negotiated settlement.
