Sandra Dinwiddie, A-GNP appears in the CMS NPPES registry as a Pain Management Registered Nurse provider holding A-GNP credentials at 20823 N CAVE CREEK RD STE 103, Phoenix, AZ, 85024, with a listed phone of (623) 439-5585. NPI 1326581547 was issued on 11/19/2016. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Dinwiddie 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 1,493 prescription claims written by this provider, covering 58 Medicare beneficiaries and totaling roughly $60K in drug spend, split 4% brand-name and 96% generic by claim count, with an opioid prescribing rate of 45.8%. 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.

Pain Management Registered Nurse is a narrow specialty nationwide, with 222 enrolled providers across 43 states and an average of 1,375 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
