Mandolin vs Plenful (2026)
Specialty pharmacy and infusion teams encounter Mandolin and Plenful across intake, benefit investigation and prior authorization. Mandolin concentrates on the operational journey toward specialty treatment; Plenful adds a substantial 340B savings, referral and rebate management platform. Mandolin's agents read referrals, enter records, call payers, estimate patient costs and assemble authorization submissions. They work through existing interfaces, fax and telephone, reducing dependence on new API connections. Medical policy review compares coverage requirements with the chart, while transcripts and action logs preserve the history of payer interactions. Clinical decisions remain with clinicians, and ambiguous records require review, though no task specific stopping rules are described. Plenful combines configurable rules, crosswalks and AI across pharmacy administration. Its Referral Agent reconstructs referrals from clinical records, matches them to claims and supports targeted staff review. The wider suite covers 340B auditing, rebate reporting and Maximum Fair Price reconciliation. Its promise to identify all revenue opportunities sits beside a reported 4% missed opportunity rate; customer efficiency figures lack full measurement methods. Neither offers a public production rate card. Mandolin fits infusion and specialty therapy operators coordinating referral intake through authorization and claim follow up across existing systems. Plenful fits pharmacy organizations combining those administrative workflows with 340B optimization, referral recovery and drug pricing reconciliation.
- Specialty treatment intake and authorization are the central workload.
- Payer phone calls and portals need automated follow up.
- The workflow must use existing interfaces without new API connections.
- Staff need call transcripts and action histories for disputed claims.
- 340B auditing and savings recovery are major requirements.
- Missing referrals need reconstruction and matching to claims.
- Rebate reporting and Maximum Fair Price reconciliation are in scope.
- Pharmacy intake should connect to broader financial administration.

Plenful automates pharmacy back-office work for health systems, specialty pharmacies and infusion teams, centered on the 340B drug pricing program. For covered entities it screens every 340B eligible claim, finds missed savings, automates rebate reporting and Maximum Fair Price reconciliation, and runs a Referral Agent that uses language models to read clinical notes and other record data, reconstruct referrals that were never coded, match them to claims and send referral documentation back to the referring provider.

Questions buyers ask
How do Mandolin and Plenful work with the EHR?
Mandolin reads referral forms, laboratory reports and clinical notes and enters the extracted information into an EHR. Benefits and claims work can use payer portals, fax and telephone, so the product is designed to operate through existing interfaces without requiring an API integration.
With Plenful, the home page says the platform connects disparate systems through PDFs, flat files, APIs, HL7, SFTP and databases, with unlimited rules and crosswalks, and the Referral Agent sends referral documentation back to the referring provider "via major EHRs". It names no record system, third party administrator, pharmacy management system or ePA network with a method or a live site.

How do Mandolin and Plenful handle patient data?
In Mandolin's case, the policy permits deidentified or aggregated information to train, validate and improve models, and requires appropriate safeguards or explicit BAA permission for outside model development. Retention follows customer instructions, contractual requirements and the purpose of processing, followed by deletion or anonymization when information is no longer needed.
The agreement says Plenful may use service data, including protected health information, to generate outputs, classifications and workflow actions for the customer, and "will not use PHI to train models for the benefit of other Plenful customers".

How much do Mandolin and Plenful leave to the clinician?
With Mandolin, the current design philosophy separates deterministic work from ambiguous material and keeps treatment necessity and safety decisions with a clinician. Its examples route contradictory diagnosis information toward human review, cross check inconsistent measurements and preserve source wording behind classifications.
In Plenful's case, the Referral Agent page describes shifting 340B teams from manual search to targeted review of claims the model flags with high confidence, with referral documentation generated and sent back to the referring provider, so a person reviews what the model surfaces.
