Does appealing a denied health-insurance claim work? Marketplace issuers ranked by the share of appeals that were OVERTURNED in the patient’s favour, plan year ${PLAN_YEAR}. Answers “is it worth appealing a denied claim”, “what percentage of insurance appeals succeed”, “how often does reverse a denial”, and which insurer most often changes its mind. Returns internal appeals (decided by the insurer itself) and external appeals (decided by an independent reviewer) separately, with how many were filed, how many were overturned, and the overturn percentage — the two differ a lot and the external number is the independent one. Sourced from the CMS Transparency in Coverage Public Use File; covers HealthCare.gov states only, so state-run exchanges such as California and New York are not present.
