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).

Dorothy Were, DNP appears in the CMS NPPES registry as a Registered Nurse provider holding DNP credentials at 3700 ODONNELL ST, Baltimore, MD, 21224, with a listed phone of (610) 834-1122. NPI 1316256068 was issued on 09/29/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Were 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 1,316 prescription claims written by this provider, covering 138 Medicare beneficiaries and totaling roughly $156K in drug spend, split 17% brand-name and 83% generic by claim count, with an opioid prescribing rate of 3.3%. 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.

Registered Nurse is a high-volume specialty nationwide, with 175,652 enrolled providers across 56 states and an average of 1,000 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.

  • Confirm the NPI record is current in the official CMS registry — providers update their own NPPES details, and moves can lag. Verify this NPI
  • Check the active license and any disciplinary history with the Maryland medical board — federal registration is not a license check. Credential verification guide
  • Weigh a second option: compare this provider with a nearby Registered Nurse peer on Medicare volume and prescribing patterns. Compare providers
