The chain drug store lobby wants CMS to institute a number of changes leading up to 2015 open enrollment to ensure that consumers seeking prescription drug coverage starting next year do not experience disruptions. In a letter to CMS Administrator Marilyn Tavenner, the National Association of Chain Drug Stores asks that CMS allow pharmacists to use “one-time overrides” of claims denials in January for difficult cases, consider having call centers remain open on holidays, and ensure that qualified health plans send beneficiary files on a timely basis.
