### What a Medical Loss Ratio is — and is NOT

**INTERPRETATION.** A Medical Loss Ratio is a spending ratio across an issuer's WHOLE book in a market for a past period — the share of premium spent on care + quality improvement versus administration and profit. It is NOT a measure of plan quality, of your individual plan's value, or of coverage availability, and it is NOT advice. A low MLR triggers a rebate; it does not rate care.

Falsifier: occurred=FALSE (a framing, not an event) and adjudged=FALSE (an in-house reading, not an authority's verdict) — the LOWEST-warrant claim here. A flat representation would render this identically to the official facts; the four-status does not.
