Sara Grubor, FNP-C appears in the CMS NPPES registry as a Pain Medicine Physician provider holding FNP-C credentials at 14520 W GRANITE VALLEY DR # 210, Sun City West, AZ, 85375, with a listed phone of (866) 974-2673. NPI 1447971999 was issued on 09/02/2022. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Grubor 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 2,347 prescription claims written by this provider, covering 331 Medicare beneficiaries and totaling roughly $153K in drug spend, split 5% brand-name and 95% generic by claim count, with an opioid prescribing rate of 55.1%. 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 Medicine Physician is a narrow specialty nationwide, with 951 enrolled providers across 49 states and an average of 2,078 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
