The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.

Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).

William Crannell, M.D. appears in the CMS NPPES registry as a Transplant Surgery Physician provider holding M.D. credentials at 3601 THE VANDERBILT CLINIC, Nashville, TN, 37232, with a listed phone of (615) 322-3000. NPI 1013302603 was issued on 04/01/2015.

Medicare Part D records for calendar year 2023 show 69 prescription claims written by this provider, covering 16 Medicare beneficiaries and totaling roughly $2K in drug spend. 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.

Transplant Surgery Physician is a narrow specialty nationwide, with 1,026 enrolled providers across 48 states and an average of 275 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.
