JOHN BARCLAY, D.O. appears in the CMS NPPES registry as a Otolaryngology/Facial Plastic Surgery Physician provider holding D.O. credentials at 2521 GLENN HENDREN DR STE 104, LIBERTY, MO, 64068, with a listed phone of (816) 781-1001. NPI 1316144223 was issued on 07/03/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BARCLAY 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 486 prescription claims written by this provider, covering 174 Medicare beneficiaries and totaling roughly $10K in drug spend, with an opioid prescribing rate of 2.5%. 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 75.5346/100 for the 2023 performance year (Quality 66.8082, Cost 51.6404), compared with the national average of 83.1.

Otolaryngology/Facial Plastic Surgery Physician is a narrow specialty nationwide, with 744 enrolled providers across 53 states and an average of 561 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.
