Margaret Macgregor, M.D. appears in the CMS NPPES registry as a Neurological Surgery Physician provider holding M.D. credentials at 5651 FRIST BLVD STE 415, Hermitage, TN, 37076, with a listed phone of (615) 467-4633. NPI 1679665541 was issued on 09/29/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Macgregor 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 157 prescription claims written by this provider, covering 60 Medicare beneficiaries and totaling roughly $2K in drug spend, with an opioid prescribing rate of 40.8%. 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.

Neurological Surgery Physician is a mid-sized specialty nationwide, with 8,100 enrolled providers across 53 states and an average of 181 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
