MARY DOELLMAN, DO appears in the CMS NPPES registry as a Allergy & Immunology Physician provider holding DO credentials at 1025 MAINE ST, QUINCY, IL, 62301, with a listed phone of (217) 222-6550. NPI 1417117854 was issued on 06/10/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DOELLMAN 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 1,068 prescription claims written by this provider, covering 298 Medicare beneficiaries and totaling roughly $62K in drug spend, with an opioid prescribing rate of 2.8%. 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 77.5232/100 for the 2023 performance year (Quality 64.8858, Cost 60.1917), compared with the national average of 83.1.

Allergy & Immunology Physician is a narrow specialty nationwide, with 3,390 enrolled providers across 52 states and an average of 764 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.
