Methodology
The scorecard evaluates each payer's monthly price transparency data against six quality criteria:
If 5–6 criteria pass, the overall rating is Good.
If 3–4 criteria pass, the rating is Acceptable.
If 0–2 criteria pass, the rating is Poor.
Behavioral, RX, and other specialty networks may not pass all criteria but can still contain complete and usable data.
