John Roll, APRN,CNS appears in the CMS NPPES registry as a Adult Health Clinical Nurse Specialist provider holding APRN,CNS credentials at 1000 HIGHWAY 12, Hettinger, ND, 58639, with a listed phone of (701) 567-4561. NPI 1487022885 was issued on 09/02/2015. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Roll 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 949 prescription claims written by this provider, covering 133 Medicare beneficiaries and totaling roughly $69K in drug spend, split 14% brand-name and 86% generic by claim count, with an opioid prescribing rate of 5.6%. 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.

Adult Health Clinical Nurse Specialist is a narrow specialty nationwide, with 1,375 enrolled providers across 49 states and an average of 1,088 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
