What is a Part D plan?
Part D plans are required to provide access to vaccines not covered under Part B. During rulemaking, CMS described use of standard out-of-network requirements to ensure adequate access to the small number of vaccines covered under Part D that must be administered in a physician’s office. CMS’ approach was based on the fact that most vaccines of interest for the Medicare population (influenza, pneumococcal, and hepatitis B for intermediate and high risk patients) were covered and remain covered under Part B. Under the out-of-network process, the beneficiary pays the physician and then submits a paper claim to his or her Part D plan for reimbursement up to the plan’s allowable charge. As there likely would be no communication with the plan prior to vaccine administration, the amount the physician charges may be different from the plan’s allowable charge, and a differential may remain that the beneficiary would be responsible for paying. As newer vaccines have entered the market with indications for use in the Medicare population, Part D vaccine in-network access has become more imperative. Requiring the beneficiary to pay the physician’s full charge for a vaccine out of pocket first and be reimbursed by the plan later is not an optimal solution, and CMS has urged Part D plans to implement cost-effective, real time billing options at the time of administration. With consideration to improve access to vaccines under the Drug Benefit without requiring up-front beneficiary payment, in May 2006, CMS issued guidance to Part D sponsors to investigate alternative approaches to ensure adequate access to Part D vaccines. CMS emphasized a solution incorporating real-time processing, given that cost sharing under Part D for non-full subsidy beneficiaries can differ depending upon where the beneficiary is in the benefit (e.g., deductible, coverage gap, and catastrophic range). CMS has outlined the following options to Part D sponsors for their consideration in a letter dated 12/1/06. (See

Is a 351 a part D?
