MADELINE CLISHAM, CRNP appears in the CMS NPPES registry as a Gerontology Nurse Practitioner provider holding CRNP credentials at 1787 SENTRY PKWY W STE 405, BLUE BELL, PA, 19422, with a listed phone of (877) 868-4827. NPI 1699292854 was issued on 08/28/2017. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CLISHAM most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal — many Gerontology Nurse Practitioner providers operate outside Part D entirely.

Gerontology Nurse Practitioner is a mid-sized specialty nationwide, with 9,625 enrolled providers across 54 states and an average of 1,283 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
