GREGORY ANDERSON, CRNA appears in the CMS NPPES registry as a Certified Registered Nurse Anesthetist provider holding CRNA credentials at 1700 W TOWNLINE ST, CRESTON, IA, 50801, with a listed phone of (641) 782-7091. NPI 1265641310 was issued on 05/22/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ANDERSON 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 783 prescription claims written by this provider, covering 127 Medicare beneficiaries and totaling roughly $59K in drug spend, split 7% brand-name and 93% generic by claim count, with an opioid prescribing rate of 38.4%. 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.

Certified Registered Nurse Anesthetist is a high-volume specialty nationwide, with 62,433 enrolled providers across 55 states and an average of 282 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
