Stacy Underwood, NP appears in the CMS NPPES registry as a Clinical Social Worker provider holding NP credentials at 1255 W BASELINE RD, Mesa, AZ, 85202, with a listed phone of (480) 820-0825. NPI 1043325541 was issued on 08/21/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Underwood 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 records for calendar year 2023 show 112 prescription claims written by this provider, covering 16 Medicare beneficiaries and totaling roughly $35K in drug spend, split 11% brand-name and 89% generic by claim count. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 93.4/100 for the 2023 performance year (Quality 94.6, Cost 62.1), compared with the national average of 83.1.

Clinical Social Worker is a high-volume specialty nationwide, with 272,898 enrolled providers across 56 states and an average of 716 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
