John Musa, MD appears in the CMS NPPES registry as a Nephrology Physician provider holding MD credentials at 605 E HOLLAND AVE, Spokane, WA, 99218, with a listed phone of (509) 838-2531. NPI 1154314367 was issued on 08/24/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Musa 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 848 prescription claims written by this provider, covering 150 Medicare beneficiaries and totaling roughly $137K in drug spend, split 13% brand-name and 87% generic by claim count, with an opioid prescribing rate of 1.5%. 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.

Nephrology Physician is a mid-sized specialty nationwide, with 10,534 enrolled providers across 55 states and an average of 1,454 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
