MARY CAMMACK, APRN appears in the CMS NPPES registry as a Critical Care Medicine Nurse Practitioner provider holding APRN credentials at 2222 S 16TH ST, LINCOLN, NE, 68502, with a listed phone of (402) 474-3704. NPI 1629052154 was issued on 11/29/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CAMMACK 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 319 prescription claims written by this provider, covering 77 Medicare beneficiaries and totaling roughly $96K in drug spend, split 57% brand-name and 43% generic by claim count, with an opioid prescribing rate of 4.1%. 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 92.3955/100 for the 2023 performance year (Quality 84.7911), compared with the national average of 83.1.

Critical Care Medicine Nurse Practitioner is a narrow specialty nationwide, with 1,410 enrolled providers across 50 states and an average of 426 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
