How ReveIQ tiers work
The ReveIQ Leverage Tier System classifies every MS-DRG by the reimbursement opportunity available through accurate documentation and coding. Tiers are derived from CMS-published relative weights, analyzed across severity-of-illness subclasses (LV1–LV4), with the ReveIQ Jump Score measuring the weight lift available from the lowest to highest subclass.
Blue Chip
LV1 ≥ 4.0 · top yield
Superior
LV1 3.0–3.99
Very High
LV1 2.0–2.99
High
LV1 1.5–1.99
Mod-High
LV1 1.0–1.49
Mod/Low
LV1 < 1.0
What this tool is (and isn't)
This calculator estimates gross reimbursement impact using DRG relative weights × hospital base rate. It does not account for outlier payments, disproportionate share adjustments, graduate medical education add-ons, or payer-specific variations. Use it for quick scenario modeling, query opportunity sizing, and CDI education. For formal contract modeling, consult your finance team.

Important disclaimer. Estimates use CMS relative weights × your base rate. Actual reimbursement depends on outlier payments, DSH/GME adjustments, and contract terms not modeled here. ReveIQ is a reference tool, not professional advice.
