KELSEY DOLL-SINGH, FNP-BC appears in the CMS NPPES registry as a Medical-Surgical Registered Nurse provider holding FNP-BC credentials at 1155 N MAYFAIR RD, WAUWATOSA, WI, 53226, with a listed phone of (414) 955-1000. NPI 1457839615 was issued on 07/31/2018. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DOLL-SINGH 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 64 prescription claims written by this provider, covering 37 Medicare beneficiaries and totaling roughly $599 in drug spend, with an opioid prescribing rate of 26.6%. 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 80.4671/100 for the 2023 performance year (Quality 66.2426, Cost 68.6477), compared with the national average of 83.1.

Medical-Surgical Registered Nurse is a narrow specialty nationwide, with 3,523 enrolled providers across 54 states and an average of 798 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.
