How CirrusMD Uses Writer to Achieve 234% More Benefits Referrals

CirrusMD sits at the intersection of patients, physicians, and plan sponsors across commercial and government health plans. Its chat-based care model connects over 13 million members with a physician in under 60 seconds—handling not just acute care but also behavioral health, chronic condition management, and primary care. Each interaction touches three parties with competing pressures: plan sponsors want members maximizing their coverage, physicians are time-constrained and information-limited, and patients face access barriers driven by cost, distance, and complexity.

The opportunity CirrusMD identified was precise: physicians who personally recommend benefits to patients drive far higher engagement than any other channel. But identifying the right benefits for a given patient—tailored to their health situation, coverage plan, age, and location—during a live care interaction was impractical without AI. At the same time, clinical documentation consumed physician time that should go to patients. CirrusMD spent a year attempting to build these capabilities in-house, cycling through GPT-3, GPT-3.5 Turbo, and GPT-4. Each model update required rebuilding pipelines from scratch. Output quality was inconsistent, and the models lacked the medical specificity required for clinical workflows. With just one ML engineer, the team was stretched thin and months behind on its first launch.

CirrusMD switched to Writer and its Palmyra Med model, a large language model trained specifically for medical language and clinical context. The Writer full-stack platform provided all the components needed to build and deploy AI-powered workflows without stitching together disparate tools or scaling an internal AI team. Writer’s services team met CirrusMD’s tight development deadlines. The first use case—real-time, patient-specific benefits recommendations surfaced to physicians at the point of care—launched in under six months. A second use case, clinical documentation automation, was completed in parallel.

The impact on benefits engagement was dramatic. Physician-directed benefits referrals increased by 234%, and patient benefits engagement rose 15x. Hundreds of thousands of patient interactions per year now flow through Writer-powered AI workflows. Physicians report that the benefits navigation feature delivers real value to patients, and plan sponsors see measurable improvement in benefits utilization—the metric they care most about.

CirrusMD’s roadmap extends the AI layer across more care categories and use cases. The shift from in-house development to Writer as a platform partner gives the company the speed and clinical reliability to expand without scaling a dedicated AI engineering function. The lesson from the transition was direct: building AI infrastructure is not CirrusMD’s core business—delivering quality care is, and Palmyra Med makes that possible at scale.
