DENIS MILLER, D.D.S. appears in the CMS NPPES registry as a Oral and Maxillofacial Surgery (Dentist) provider holding D.D.S. credentials at 6401 S MINNESOTA AVE, SIOUX FALLS, SD, 57108, with a listed phone of (605) 335-1080. NPI 1821069253 was issued on 02/01/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MILLER 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 918 prescription claims written by this provider, covering 313 Medicare beneficiaries and totaling roughly $7K in drug spend, with an opioid prescribing rate of 25.9%. 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 79.5985/100 for the 2023 performance year (Quality 83.9127, Cost 49.7489), compared with the national average of 83.1.

Oral and Maxillofacial Surgery (Dentist) is a mid-sized specialty nationwide, with 7,631 enrolled providers across 52 states and an average of 378 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
