COLLEEN CASTELEIN, RN, CNP appears in the CMS NPPES registry as a Acute Care Nurse Practitioner provider holding RN, CNP credentials at 11100 EUCLID AVE, CLEVELAND, OH, 44106, with a listed phone of (216) 844-1006. NPI 1366540874 was issued on 09/20/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CASTELEIN 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 321 prescription claims written by this provider, covering 101 Medicare beneficiaries and totaling roughly $86K in drug spend, split 16% brand-name and 84% generic by claim count, with an opioid prescribing rate of 21.2%. 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 79.4829/100 for the 2023 performance year (Quality 68.5144, Cost 63.0952), compared with the national average of 83.1.

Acute Care Nurse Practitioner is a mid-sized specialty nationwide, with 24,583 enrolled providers across 53 states and an average of 576 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.
