How often can a PDP or MA-PD change providers?

A Medicare Prescription Drug Plan (PDP) or a Medicare Advantage Plan with Prescription Drug coverage (MA-PD) can generally change their formulary or preferred pharmacy network on an annual basis. This aligns with the Medicare guidelines that allow these plans to offer a comprehensive review of their provider networks and drug formularies each year, typically during the annual enrollment period.

Annual changes give beneficiaries a clear and predictable timeframe within which they can understand potential modifications in their coverage options, making it easier for them to evaluate their needs and make informed decisions regarding their healthcare plans.

Other timeframes, such as monthly, quarterly, or biannually, do not match the regulations set forth by Medicare regarding the frequency of provider network changes in PDPs or MA-PDs. This is why the option of annual changes is the appropriate answer in this context.
