PATRICIA CANTLIN, DO appears in the CMS NPPES registry as a Nephrology Physician provider holding DO credentials at 1600B CONGRESS ST, PORTLAND, ME, 04102, with a listed phone of (207) 774-5222. NPI 1275533994 was issued on 07/22/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CANTLIN 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 460 prescription claims written by this provider, covering 117 Medicare beneficiaries and totaling roughly $75K in drug spend, split 13% brand-name and 87% generic by claim count. 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 98.0699/100 for the 2023 performance year (Quality 86.1398), compared with the national average of 83.1.

Nephrology Physician is a mid-sized specialty nationwide, with 10,534 enrolled providers across 55 states and an average of 1,454 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
