A lower-cost site of care your patients will prefer.
Payers increasingly direct specialty infusions away from hospital outpatient departments. Sunlit gives your patients an office-based option with no hospital facility fee, infusion-trained nurses and a supervising provider on site.
You stay the prescriber. We follow your order, and we call you before anything changes.
Similar outcomes, about 40% lower outpatient cost.
A 2026 matched-cohort study of more than 52,000 infusions compared hospital outpatient departments with other sites of care and found similar adverse event rates and adherence, with hospital outpatient costs about 40% higher.
