JOSEPH KROB, MD appears in the CMS NPPES registry as a Sports Medicine (Orthopaedic Surgery) Physician provider holding MD credentials at 555 BIESTERFIELD RD, ELK GROVE VILLAGE, IL, 60007, with a listed phone of (847) 690-1776. NPI 1639630197 was issued on 03/27/2019. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what KROB 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 30 prescription claims written by this provider, covering 21 Medicare beneficiaries and totaling roughly $1K in drug spend, with an opioid prescribing rate of 46.7%. 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.

Sports Medicine (Orthopaedic Surgery) Physician is a narrow specialty nationwide, with 2,681 enrolled providers across 53 states and an average of 278 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.
