ROBERT BOHNENSTIEHL, APN appears in the CMS NPPES registry as a Nurse Practitioner provider holding APN credentials at 650 S RANDALL RD, ALGONQUIN, IL, 60102, with a listed phone of (779) 771-7000. NPI 1881367712 was issued on 07/27/2021. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BOHNENSTIEHL 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 664 prescription claims written by this provider, covering 452 Medicare beneficiaries and totaling roughly $5K in drug spend, with an opioid prescribing rate of 30.7%. 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 70.9963/100 for the 2023 performance year (Quality 61.0071, Cost 63.9806), compared with the national average of 83.1.

Nurse Practitioner is a high-volume specialty nationwide, with 87,227 enrolled providers across 56 states and an average of 1,084 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
