RxAI | AI Pharmacy Claim Validation Platform | Grelin Health
Validate pharmacy claims against payer rules, formularies, prior authorization, REMS, and clinical documentation before claims are submitted.

Most pharmacy denials are created long before billing ever sees the claim.
Patient Access Origin
They start at patient access. In documentation. In payer specific logic that no one validates until the rejection comes back.
Revenue at Extreme Risk
By then the patient has left the pharmacy. The revenue is at risk. Someone on the team is rebilling or refiling or writing it off.
Not a Billing Failure
The denial was not a billing failure. The conditions that caused it existed before the claim was ever created.
A decisioning layer that sits ahead of the claim.
RxAI validates every prescription against payer rules, formularies, prior authorization requirements, step therapy logic, and FDA indication data.
The system runs in under five seconds and exits every prescription with one clear decision and one clear owner. No prescription leaves the queue without a routing.

BRIVIACT 50mg
Humana Medicare Advantage
Formulary Exclusion
Step therapy requires documented failure of two generic alternatives.
Levetiracetam 500mg
Covered Generic Substitution
Prescriber Approved
Formulary citation and clinical equivalence note populated automatically. Claim paid.
From blocked to payable in one click.
BRIVIACT, brand-name antiepileptic, written for a patient on Humana.
RxAI flags it. Humana formulary excludes BRIVIACT in this plan year. Step therapy requires documented failure of two generic alternatives.
RxAI surfaces levetiracetam as the covered generic. The substitution is routed to the prescriber with the formulary citation and the clinical equivalence note already populated.
The prescriber approves. The new claim is submitted, validated, and paid.
Built for the operators who carry the rejection cost.
Physician groups and specialty practices
High-denial verticals where prior auth volume and step therapy complexity drive rework.
MSOs and health systems
Prescription volume across multiple specialties and payer mixes.
Pharma distributors
Decisioning embedded at the dispense point to defend pharmacy customer economics.
Specialty pharmacies
High-cost therapies where a single rejection has six-figure margin impact.
Sits between your prescribing layer and your claims infrastructure.
RxAI ingests prescriptions from EHRs, pharmacy systems, provider portals, and direct e-prescribing feeds. It normalizes, enriches, and decides. It routes the outcome back into the workflow you already run.
No rip-and-replace. No new screens to train on. The decision shows up where the work already happens.
Integrations
Implementation
Data integration and payer rule library tuning.
Two to four weeks.
Shadow decisioning against live prescription volume.
Two to three weeks.
Production go-live with full routing into existing workflows.
Two to three weeks.
A correctly written prescription and a payable claim are not the same thing.
Most pharmacy rework is created upstream of billing. Eligibility gaps. Formulary mismatches. Step therapy documentation that never made it into the chart.
Each one looks like a billing problem on the way out. None of them started there.
RxAI moves the decision back to where the problem actually originates.
