MARTIN CORNETT, CRNA appears in the CMS NPPES registry as a Certified Registered Nurse Anesthetist provider holding CRNA credentials at 3911 AMBROSIA ST STE 201, CASTLE ROCK, CO, 80109, with a listed phone of (303) 788-8888. NPI 1447426812 was issued on 05/05/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CORNETT 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 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 Certified Registered Nurse Anesthetist providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 75/100 for the 2023 performance year, compared with the national average of 83.1.

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. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. 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.
