KELLY LANG-SHEPPARD, APRN-CNS appears in the CMS NPPES registry as a Clinical Nurse Specialist provider holding APRN-CNS credentials at 5401 N PORTLAND AVE STE 410, OKLAHOMA CITY, OK, 73112, with a listed phone of (405) 945-4700. NPI 1972940708 was issued on 06/03/2013. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what LANG-SHEPPARD 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 3,097 prescription claims written by this provider, covering 260 Medicare beneficiaries and totaling roughly $2.4 million in drug spend, split 64% brand-name and 36% 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 77.6983/100 for the 2023 performance year (Quality 82.5298, Cost 43.1313), compared with the national average of 83.1.

Clinical Nurse Specialist is a narrow specialty nationwide, with 1,708 enrolled providers across 49 states and an average of 953 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.
