Elizabeth Arnold, RD appears in the CMS NPPES registry as a Registered Dietitian provider holding RD credentials at 201 N MAYFAIR RD, Wauwatosa, WI, 53226, with a listed phone of (414) 771-8228. NPI 1093248213 was issued on 04/05/2017.

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 Registered Dietitian providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 82.4/100 for the 2023 performance year (Quality 77.9, Cost 74.4), compared with the national average of 83.1.

Registered Dietitian is a high-volume specialty nationwide, with 64,580 enrolled providers across 55 states and an average of 696 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
