Built for Health Plan Performance
MedArk™ is our Medicare Part D module, built directly within OneArk®. Compliance, quality reporting, and clinical protection run on the same platform already handling your commercial claims.

Why one gap is all it takes
Compliance, quality reporting, and member experience usually live on systems that were never built to talk to each other. Every disconnect is a place risk can hide, until an audit, a STARS score, or a member call surfaces it. MedArk™ changes that.
Powerful enough for Medicare complexity. Configurable enough to run it your way.
MedArk™ brings every layer of Medicare pharmacy benefit management into one proprietary environment, so nothing falls through the gaps. Built and controlled by your team, configured to how your plan already runs, not a fixed system you have to adapt to.
Compliance
CMS compliance and audit-ready documentation at every step.
Core operations
Real-time claims adjudication and eligibility validation.
STARS & clinical quality
STARS performance tracking and MTM reporting in one system.
Clinical outcomes
Clinical program outcomes — not just paid claims
Compliance and operations, running as one
Filings and audit trails get generated as the claim moves, not reconstructed later. The same real-time engine runs operations too, adjudication, specialty integration, and network visibility, available the moment you need them.

STARS data. Ready at any moment.
MTM-eligible members are identified as claims process, not pulled from a list assembled later. Adherence and formulary compliance are tracked continuously, so by the time CMS asks, the record already exists in the format they expect.
MTM identification and reporting
Drug utilization review (DUR)
Clinical edits review
Adherence and formulary compliance reporting
FWA detection and polypharmacy support
STARS-aligned, audit-ready documentation
Behind every audit and every score is a person trying to get their medication.
Integrated member and prescriber portals give real-time eligibility, formulary access, and plan information, backed by a dedicated Part D team and first-level resolution, so the person on the other end of the call gets an answer, not a transfer.

The view from inside the benefit
Expert insights from pharmacists and PBM operators with an inside view of where pharmacy decisions break down, what those gaps cost, and how they affect benefit performance.
