Rachel Armstrong, PHARMD appears in the CMS NPPES registry as a Geriatric Pharmacist provider holding PHARMD credentials at 231 S ARTHUR AVE, Pocatello, ID, 83204, with a listed phone of (208) 233-2444. NPI 1629417720 was issued on 06/21/2013.

Medicare Part D prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal, many Geriatric Pharmacist providers operate outside Part D entirely.

Geriatric Pharmacist is a narrow specialty nationwide, with 1,267 enrolled providers across 51 states and an average of 129 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
