ELLEN GRISHMAN, MD appears in the CMS NPPES registry as a Pediatric Endocrinology Physician provider holding MD credentials at 262 DANNY THOMAS PL, MEMPHIS, TN, 38105, with a listed phone of (888) 226-4343. NPI 1720035785 was issued on 05/27/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GRISHMAN 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 Pediatric Endocrinology Physician providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 74.5984/100 for the 2023 performance year (Quality 56.1252, Cost 59.2027), compared with the national average of 83.1.

Pediatric Endocrinology Physician is a narrow specialty nationwide, with 1,457 enrolled providers across 51 states and an average of 151 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.
