The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.

Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).

JANE HAMMETT is a Ambulatory Care Registered Nurse provider practicing in MISSOULA, Montana, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1619410172. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.

JANE HAMMETT appears in the CMS NPPES registry as a Ambulatory Care Registered Nurse provider at 900 N ORANGE ST STE 103, MISSOULA, MT, 59802, with a listed phone of (406) 329-5776. NPI 1619410172 was issued on 11/30/2016. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HAMMETT 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 Ambulatory Care Registered Nurse providers operate outside Part D entirely.

Ambulatory Care Registered Nurse is a narrow specialty nationwide, with 3,123 enrolled providers across 53 states and an average of 695 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.
