Buffalo County, Wisconsin

Each issuer, and the file it registers

Every column is CMS’s own record: who sells here, how many plans, and the provider directory file each issuer registers. Rollcall Health reads those files and publishes one market-wide measurement; it does not publish a result for any file, and neither does this page.

Plans from the CMS Landscape file, plan year 2026. Directories read on 2026-08-30. A registration maps an issuer to the directory file it publishes under 45 CFR 156.230(b)(2). The host serving that file may be a vendor or a shared platform; the registration does not say who operates the server, and none of this is a statement about directory accuracy or network participation. Statewide coverage: Wisconsin

What this page is not

• It is not a plan recommendation. No premium, no ranking, and no result of any kind: issuers are listed alphabetically. Costs and coverage live on HealthCare.gov, which is where a plan should be chosen.
• It carries no Rollcall Health result. The audit measures published directory files and reports one market-wide level; nothing published about the current run says what was found in any named plan’s file, and a plan receives its own findings on request.
• It is not a statement about any doctor. Nothing here says whether a listing in a directory is right, and nothing here is about any clinician.
• It is not a network claim. A directory listing a doctor is not the doctor accepting the plan, and a doctor absent from it is not out of network. Rollcall Health does not resolve either question, and does not try.
• The host is not the plan. Directories are often published by a vendor or a shared platform. The registration maps an issuer to a file; it does not say who operates the server.
