Rachael Stillwagon, P.A. appears in the CMS NPPES registry as a Allergy & Immunology Physician provider holding P.A. credentials at 10200 N 92ND ST STE 130, Scottsdale, AZ, 85258, with a listed phone of (480) 614-8011. NPI 1437174208 was issued on 07/13/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Stillwagon 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 763 prescription claims written by this provider, covering 157 Medicare beneficiaries and totaling roughly $536K in drug spend. 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.

Allergy & Immunology Physician is a narrow specialty nationwide, with 3,390 enrolled providers across 52 states and an average of 764 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
