Isaac Kramer, MD appears in the CMS NPPES registry as a Specialist provider holding MD credentials at 101 OLD SHORT HILLS RD STE 440, West Orange, NJ, 07052, with a listed phone of (973) 716-0300. NPI 1104829712 was issued on 05/27/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Kramer 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 3,176 prescription claims written by this provider, covering 346 Medicare beneficiaries and totaling roughly $371K in drug spend, split 9% brand-name and 90% generic by claim count, with an opioid prescribing rate of 0.8%. 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.

Specialist is a high-volume specialty nationwide, with 69,658 enrolled providers across 55 states and an average of 1,474 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
