HEIDI GROSSKOPF, AU.D. appears in the CMS NPPES registry as a Audiologist provider holding AU.D. credentials at 2251 N SHORE DR, RHINELANDER, WI, 54501, with a listed phone of (715) 361-4700. NPI 1104863026 was issued on 05/31/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GROSSKOPF 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 prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal — many Audiologist providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 84.5617/100 for the 2023 performance year (Quality 89.8049, Cost 58.7342), compared with the national average of 83.1.

Audiologist is a mid-sized specialty nationwide, with 20,422 enrolled providers across 56 states and an average of 500 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.
