About CaseWhy Appeals
CaseWhy Appeals is a product of CaseWhy LLC, a Florida limited liability company. It helps people understand and respond to Medicare Advantage coverage denials — explaining what a denial means, tracking the deadlines that apply, and preparing an appeal letter and supporting forms.
CaseWhy Appeals is not affiliated with or endorsed by Medicare, the Centers for Medicare & Medicaid Services (CMS), or any health plan. It is not a law firm and does not provide legal advice.
How this content is produced
The explanatory pages on this site — what a denial means, what a notice means, what a winning appeal has to show, and what to do in situations beyond a straightforward appeal — are generated directly from the same structured rule data that powers the product itself: the specific coverage rule for each denied service, the real deadline calculations, and the evidence a rule actually calls for.
Every rule claim links to its real source — a federal regulation, CMS guidance, or a national coverage determination — through the same citation-checking system the product uses when it explains your own case. A claim that can't be traced to a real, checkable source isn't published; that's a hard rule in how this content is built, not a guideline.
Peter, who runs CaseWhy, reviews this content before it's published and periodically after, to confirm it still reflects the current rules. Content is not written by an outside freelancer or an anonymous author — the byline "CaseWhy Appeals editorial" means it reflects the product's own rule data, reviewed by the person responsible for the product.

Rules change, and we'd rather know about a mistake than have it sit uncorrected. Email appeals@casewhy.com with the page and what looks wrong.
