About Bay Area Endocrinology

What is Bay Area Endocrinology?

Bay Area Endocrinology is a concierge endocrine practice at 1735 Jefferson Street in Napa, California. Its main work is endocrine care: thyroid disorders, diabetes management, hormone therapy, metabolic health, and FibroScan liver measurement. The practice lists 15+ years of experience and says it is accepting new patients.

Do-Eun Lee, MD, is the physician the practice names, and Dr. Lee is a board-certified endocrinologist. Dr. Lee earned an MD at Seoul National University College of Medicine, completed an internal medicine residency, and holds ABIM board certification in endocrinology.

Hormone therapy covers bioidentical hormone therapy, adrenal evaluation, testosterone optimization, and menopause management. Weight management is listed under metabolic health, but no medical weight loss medication or program is named. The practice describes its visits this way: "No rushed appointments. No one-size-fits-all protocols."

What does it cost?

Bay Area Endocrinology works on a direct-pay model. It bills Medicare only and does not bill commercial or private insurance, so anyone with other coverage pays these fees directly, with payment due at the time of service. A superbill is given at each visit for out-of-network reimbursement.

The new patient consultation is $650, with a $200 deposit at scheduling that is applied to the visit fee. A return visit is $280. Medicare patients pay a one-time $300 registration fee at booking. The annual membership has a $600 enrollment fee, then $150 a month for 11 months, with all visits included. Thyroid ultrasound is $150, a biopsy is $350, FibroScan is $150, and e-visits are $75 for simple or $150 for complex. Prior authorization or appeals are $50 per effort.

Cancelling or rescheduling with less than 24 hours' notice carries a fee: $650 for a new patient consultation or $280 for a follow-up for self-pay patients, and $99 for Medicare patients.

The practice does not publish hormone therapy prices. It also does not say whether hormone medication is included in any price, and membership cancellation terms are not stated.

What should you ask before you book?

Ask whether the monthly membership or any visit fee includes hormone medication, and what the medication itself costs. Ask whether it is brand-name or compounded, and who writes and renews the prescription. Dr. Lee is the only prescriber the practice names, so ask who covers when Dr. Lee is away.

Ask what follow-up visits and lab work cost beyond the membership, whether telehealth is available, since it is not stated, and how the membership is cancelled and what happens after the 11 months. Ask whether the $200 deposit is refundable, and whether the $300 Medicare registration fee applies if you do not have Medicare.

Who is it a good fit for?

This is a good fit if you want an endocrinologist as your main physician for thyroid, hormone, or diabetes care, you can pay the fees directly, and you live in or near Napa or Sonoma and can book during weekday office hours, 8 AM to 4 PM. If you are looking for a named medical weight loss program or peptide care, ask first, because neither is listed.
