Nicholas Warren, M.D. appears in the CMS NPPES registry as an Emergency Medicine Physician provider holding M.D. credentials at 2525 GLENN HENDREN DR, Liberty, MO, 64068, with a listed phone of (816) 792-7000. NPI 1225424153 was issued on 04/07/2015.

Medicare Part D records for calendar year 2023 show 185 prescription claims written by this provider, covering 160 Medicare beneficiaries and totaling roughly $10K in drug spend, with an opioid prescribing rate of 14.6%. On the CMS Merit-based Incentive Payment System, this provider carries a Final Score of 75/100 for the 2023 performance year, but CMS published no Quality, Promoting Interoperability, Improvement Activity or Cost score: this is the neutral performance threshold CMS assigns where nothing was scored, so it is not comparable with clinicians whose score was measured.

Emergency Medicine Physician is a high-volume specialty nationwide, with 64,463 enrolled providers across 56 states and an average of 352 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
