Requiring entities offering medicare advantage coverage in Washington to provide certain disclosures to consumers.

HB 1639 requires Medicare Advantage insurance providers operating in Washington to disclose three specific details to current and potential enrollees: their claims denial rate (as a percentage), the percentage of denied claims later approved on appeal, and the appeals process. These disclosures must be provided before enrollment and upon request after enrollment. The bill states that failing to provide these disclosures violates Washington’s Consumer Protection Act (Chapter 19.86 RCW), classifying such failures as unfair or deceptive practices. This legislation directly affects Medicare Advantage entities serving Washington residents, aiming to increase transparency in coverage decisions.
