KYLEE MACLACHLAN appears in the CMS NPPES registry as a Hematology (Internal Medicine) Physician provider at 250 E 77TH ST APT 5A, NEW YORK, NY, 10075, with a listed phone of (929) 318-9505. NPI 1053920793 was issued on 07/29/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MACLACHLAN 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 428 prescription claims written by this provider, covering 63 Medicare beneficiaries and totaling roughly $2.1 million in drug spend, 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 79.0323/100 for the 2023 performance year (Quality 69.4497), compared with the national average of 83.1.

Hematology (Internal Medicine) Physician is a narrow specialty nationwide, with 1,436 enrolled providers across 50 states and an average of 693 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.
