JACK MCLENDON, M.D. appears in the CMS NPPES registry as a Internal Medicine Physician provider holding M.D. credentials at 1120 S JACKSON HWY, SHEFFIELD, AL, 35660, with a listed phone of (256) 383-4447. NPI 1588750566 was issued on 10/05/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MCLENDON 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 4,042 prescription claims written by this provider, covering 592 Medicare beneficiaries and totaling roughly $376K in drug spend, split 11% brand-name and 89% 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.

Internal Medicine Physician is a high-volume specialty nationwide, with 172,858 enrolled providers across 56 states and an average of 2,716 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.
