Janelle Colquhoun, ANP-B.C. appears in the CMS NPPES registry as a Adult Health Nurse Practitioner provider holding ANP-B.C. credentials at 3495 BAILEY AVE, Buffalo, NY, 14215, with a listed phone of (716) 862-8858. NPI 1639542483 was issued on 11/02/2015. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Colquhoun 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 1,273 prescription claims written by this provider, covering 236 Medicare beneficiaries and totaling roughly $72K in drug spend, split 3% brand-name and 97% generic by claim count. 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.

Adult Health Nurse Practitioner is a mid-sized specialty nationwide, with 29,492 enrolled providers across 55 states and an average of 1,201 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
