Struggling to write budget impact language that payers trust—without drifting into cost‑effectiveness claims? In this lesson, you’ll learn to craft precise, payer‑centered BIM narratives that separate PMPM affordability from ICER/QALY value and spotlight the real drivers: eligibility, utilization, price, and time horizon. You’ll find clear, step‑wise guidance, model‑neutral phrasing templates, real‑world examples, and targeted exercises to test compliance and nuance. The tone is calibrated and audit‑ready—equipping you to produce defensible RWE‑anchored value stories under strict guardrails.
