JAMES COLAR, RN appears in the CMS NPPES registry as a Ambulatory Care Registered Nurse provider holding RN credentials at 3601 W 13 MILE RD, ROYAL OAK, MI, 48073, with a listed phone of (248) 898-5983. NPI 1639436975 was issued on 04/11/2012. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what COLAR 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 550 prescription claims written by this provider, covering 178 Medicare beneficiaries and totaling roughly $111K in drug spend, split 17% brand-name and 83% 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 80.9905/100 for the 2023 performance year (Quality 67.2503, Cost 59.7327), compared with the national average of 83.1.

Ambulatory Care Registered Nurse is a narrow specialty nationwide, with 3,123 enrolled providers across 53 states and an average of 695 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.
