KATHERINE JANTAC, GNP-BC appears in the CMS NPPES registry as a Gerontology Nurse Practitioner provider holding GNP-BC credentials at 6334 CEDAR LN, COLUMBIA, MD, 21044, with a listed phone of (410) 531-2355. NPI 1770635187 was issued on 01/17/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what JANTAC 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 1,264 prescription claims written by this provider, covering 124 Medicare beneficiaries and totaling roughly $134K in drug spend, split 10% brand-name and 90% generic by claim count, with an opioid prescribing rate of 14.0%. 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 91.9618/100 for the 2023 performance year (Quality 97.0727, Cost 67.7728), compared with the national average of 83.1.

Gerontology Nurse Practitioner is a mid-sized specialty nationwide, with 9,625 enrolled providers across 54 states and an average of 1,283 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.
