Reviewed by [Christian Espinosa, Founder, Blue Goat Cyber](/authors/christian-espinosa) Last reviewed May 9, 2026 ## Definition A Budget Impact Model (BIM) projects the financial impact to a specific payer (commercial plan, Medicare, integrated health system) of adopting a new technology, typically over 3-5 years, accounting for population size, uptake curve, acquisition cost, offset costs (avoided procedures, hospitalizations, complications), and net budget effect. BIM complements cost-effectiveness analysis but answers a different question: 'Can the payer afford it?' rather than 'Is it good value per [QALY](/terms/qaly)?' What the regulation says Methodology: ISPOR Budget Impact Analysis Good Practice Task Force II report (2014). AMCP Format requires a BIM as part of US payer submissions. ## What this means in practice Most US payer access decisions are influenced more by BIM than by cost-effectiveness analysis, because US payers typically don't apply a formal [QALY](/terms/qaly) threshold. A clean, defensible BIM with conservative offset assumptions is often the deciding artifact. Common pitfalls - • Overstating offset savings (avoided procedures), payers discount aggressive assumptions heavily. - • Modeling national populations when the payer cares only about its own enrolled population. ## Related terms Grouped by theme ### Editor's picks · Hand-selected related concepts [ Reimbursement Value-Based Care(VBC) Payment tied to outcomes and total cost of care, not volume of services. ](/terms/value-based-care)[ Reimbursement Health Economics and Outcomes Research(HEOR) Research discipline that generates economic, clinical, and patient-reported evidence to support payer access, HTA submissions, and value demonstration. ](/terms/heor)[ Reimbursement Incremental Cost-Effectiveness Ratio(ICER) Cost per additional unit of health outcome (often QALY) versus comparator. ](/terms/icer)[ Reimbursement Quality-Adjusted Life Year(QALY) Outcome metric combining length and quality of life used in HTA. ](/terms/qaly) ### Reimbursement & Market Access · From this learning path [ Reimbursement Health Technology Assessment(HTA) Systematic evaluation of clinical and economic value of a health technology.
