Katherine Ketz, APRN appears in the CMS NPPES registry as a Women's Health Nurse Practitioner provider holding APRN credentials at 701 E CHANNEL ST, Stockton, CA, 95202, with a listed phone of (209) 944-4700. NPI 1427524156 was issued on 10/20/2018. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Ketz 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 101 prescription claims written by this provider, covering 35 Medicare beneficiaries and totaling roughly $4K 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.

Women's Health Nurse Practitioner is a mid-sized specialty nationwide, with 9,452 enrolled providers across 55 states and an average of 262 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
