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).

Mary Rockefeller appears in the CMS NPPES registry as a Home Health Aide provider at 1621 LYMAN PL NE, Washington, DC, 20002, with a listed phone of (202) 636-1130. NPI 1326454265 was issued on 07/10/2014. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Rockefeller 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 240 prescription claims written by this provider, covering 28 Medicare beneficiaries and totaling roughly $14K in drug spend, split 8% brand-name and 92% generic by claim count, with an opioid prescribing rate of 7.1%. 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.

Home Health Aide is a mid-sized specialty nationwide, with 46,670 enrolled providers across 53 states and an average of 358 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.

Before you book an appointment

Use this federal record as your verification checklist, not as a recommendation.

  • 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 District of Columbia medical board — federal registration is not a license check. Credential verification guide
  • Weigh a second option: compare this provider with a nearby Home Health Aide peer on Medicare volume and prescribing patterns. Compare providers

Medicare Part D and MIPS figures describe practice patterns in federal programs only — they are not quality ratings, and PlainDoctor does not rate, rank, or recommend providers.
