GRACIELA SIRONICH-KALKAN, M.D. appears in the CMS NPPES registry as a General Practice Physician provider holding M.D. credentials at 765 S MAIN ST, MANCHESTER, NH, 03102, with a listed phone of (603) 625-1724. NPI 1760751531 was issued on 12/22/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SIRONICH-KALKAN 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 1,720 prescription claims written by this provider, covering 68 Medicare beneficiaries and totaling roughly $352K in drug spend, with an opioid prescribing rate of 1.9%. 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.

General Practice Physician is a mid-sized specialty nationwide, with 16,677 enrolled providers across 56 states and an average of 2,872 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
