Frequently Asked Questions

Our directory lists 1 Los Altos practice whose true primary specialty on file is obesity medicine, endocrinology, or bariatric care, plus 2 clinics and medical centers and 1 primary-care clinician whose CMS record also lists an obesity-medicine or endocrinology taxonomy — 4 in total. Every count comes from the CMS National Provider registry (NPPES) taxonomy on file, not a survey of services.
The registry records each practice's specialty taxonomy, not the specific medications it prescribes or its current service menu. family or internal medicine is the most common taxonomy bucket among Los Altos listings in this directory (2 of 4 practices). Obesity-medicine and endocrinology practices commonly prescribe GLP-1 medications like semaglutide (Wegovy, Ozempic) and tirzepatide (Zepbound, Mounjaro), but we can't confirm any individual Los Altos clinic's offerings from the registry alone — call the practice directly to confirm availability, pricing, and new-patient status before booking.
It depends on your insurance and the medication. An in-person visit plus a brand-name prescription (Wegovy or Zepbound) can run $1,000-$1,350 per month without insurance, while licensed telehealth providers shipping compounded semaglutide or tirzepatide to California addresses average around $219/month cash-pay. Compare current cash-pay pricing from the featured California telehealth partners in the "In-Person vs Telehealth" section above.
Every listing is sourced from the CMS National Provider registry (NPPES), the federal database of enumerated healthcare providers. We verified 1 primary-specialty practices, 2 facility-type listings, and 1 primary-care clinicians in Los Altos this way — 4 listings in total. If you don't find a fit here, nearby Mountain View has a larger directory (20 listings). Listing reflects the taxonomy on file — it is not an endorsement, and not a confirmation of GLP-1 availability, cash-pay pricing, or new-patient status.
