Your percentile allowed amounts don't live in your chargemaster.
Since 1 January 2026, every hospital machine-readable file must carry the median, 10th percentile and 90th percentile allowed amounts — plus the count behind each — for every item, service and payer plan. CMS requires those figures be computed from EDI 835 remittance data over a 12–15 month lookback. That is a claims-data job, not a pricing export, which is why an EHR pricing module cannot produce it. We build that piece. Three to six weeks, fixed fee.
CMS began enforcing the CY2026 requirements on 1 April 2026 and has issued more than 1,200 noncompliance warning letters to date.
