Gail Quackenbush, M.D. appears in the CMS NPPES registry as a Diagnostic Ultrasound Physician provider holding M.D. credentials at 56 DOWNEY DR, Tenafly, NJ, 07670, with a listed phone of (201) 694-0674. NPI 1245271048 was issued on 06/10/2006.

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 Diagnostic Ultrasound Physician providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 83.6/100 for the 2023 performance year (Quality 80.7), compared with the 83.5 average among clinicians with a measured score.

Diagnostic Ultrasound Physician is a narrow specialty nationwide, with 434 enrolled providers across 46 states and an average of 682 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
