ABIGAIL DOYLE, D.O. appears in the CMS NPPES registry as a Sleep Medicine (Internal Medicine) Physician provider holding D.O. credentials at 755 S MILWAUKEE AVE STE 181, LIBERTYVILLE, IL, 60048, with a listed phone of (847) 855-2460. NPI 1861755498 was issued on 06/19/2012. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DOYLE 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 774 prescription claims written by this provider, covering 136 Medicare beneficiaries and totaling roughly $482K in drug spend, split 59% brand-name and 41% generic by claim count. 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.

Sleep Medicine (Internal Medicine) Physician is a narrow specialty nationwide, with 857 enrolled providers across 52 states and an average of 1,310 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.
