Muhammad Riaz, M.D appears in the CMS NPPES registry as a Hospitalist Physician provider holding M.D credentials at 1615 DELAWARE ST, Longview, WA, 98632, with a listed phone of (360) 414-7800. NPI 1053610493 was issued on 03/24/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Riaz 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 273 prescription claims written by this provider, covering 99 Medicare beneficiaries and totaling roughly $18K in drug spend, split 10% brand-name and 90% 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.

Hospitalist Physician is a mid-sized specialty nationwide, with 16,825 enrolled providers across 54 states and an average of 888 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
