Abstract
Rule: CMS-9882-F, the tri-agency Transparency in Coverage (TiC) final rule. Filed for public inspection Oct. 5, 2026, and scheduled for Federal Register publication Oct. 6, 2026; 338 Federal Register pages. The final rule is effective 60 days after official publication.
What changed: one INN file per network with a network name and ID, OON files split into 4 markets with an 11-claim floor, quarterly posting, a single format (JSON), an exec attestation, three new files (Taxonomy, Utilization, Text) and cost estimates by phone.
What got cut: the Change-log File, enrollment totals, claims volume, any retention mandate, any API, any CMS-run registry of network IDs.
The rule’s own numbers: 1,303 issuers, 205 TPAs, about 2.77M ERISA plans, about 300 file users, roughly $400M one-time cost, $80.4M a year ongoing, $174.5M a year net savings from year two.
Thesis: parsing gets cheap, so the national rate warehouse stays the VC lane. The bootstrapped lane is whatever the Departments declined to standardize, plus the chores a 40-person filer can’t staff.
Plays: compliance kit, attestation QA, phone estimate line, network ID registry, percent-of-charge dollarizer, diff feed and archive, taxonomy compiler and denial lookup, utilization rosters, OON benchmarks, employer graph.
Dates: Jan 1, 2027 plan years (phone), five months after publication (first new INN and OON files), 11 months after publication (Taxonomy and Text Files), Dec 2027 (Rx files), and the first Utilization File 21 months after publication.
