Dr. Edward Gerstenfeld, MD (San Francisco, CA Cardiology): GreatDoc™ Score, Real Patient Reviews, Procedure Volume & First-Visit Guide.

Annual CMS Part B utilization data tracks every office consultation (CPT 99204/99214), diagnostic evaluation, and therapeutic procedure billed for Medicare beneficiaries at 400 Parnassus Ave, San Francisco, CA 94143. Maintaining a 67th-percentile statewide volume means Dr. Gerstenfeld's clinic manages high-complexity Cardiology cases every week rather than occasional referrals ^[1][2].

Original Medicare Part B covers 80% of the Medicare-approved amount for participating Cardiology specialist visits (CPT 99204/99214) after your annual Part B deductible is met, with Medigap supplemental policies typically covering the remaining 20% coinsurance ^[2].

Before your appointment at 400 Parnassus Ave, confirm that your specific commercial PPO/HMO plan tier or Medicare Advantage network is active with the practice billing tax ID, or ask the billing desk for their direct prompt-pay rate and an itemized CPT 99204 superbill ^[1][2].

The Proprietary DotMD™ J3 Model evaluates practicing U.S. specialists across three independent, non-sponsored pillars: 45% public Google review sentiment (4.2 ★ across 5 reviews), 35% federal CMS Medicare Part B procedure volume (67th percentile in CA), and 20% bedside communication and credential longevity ^[1][2][3].

Unlike commercial physician directories where doctors can pay for "Featured" placement, every GreatDoc™ Score on dotMD is calculated directly from federal CMS utilization records (NPI #1972531788) and verified patient feedback.

Because a new-patient Cardiology consultation (CPT 99204/99205) focuses on longitudinal trends rather than isolated snapshots, having 2–3 prior lab panels side-by-side prevents duplicate blood draws and allows Dr. Gerstenfeld to establish a treatment plan on Day 1.

Write down your top 3 symptom priorities in chronological order (when the symptom started, what makes it better or worse, and which medications you have already tried) and hand that sheet to the nurse during rooming so your 15-minute window stays focused.

Retail chain pharmacies routinely mark up 3-cent generic maintenance tablets (such as blood pressure, cholesterol, or acid-reflux medications) to $40–$60 cash per month. Asking Dr. Gerstenfeld to send 90-day generic maintenance prescriptions to transparent cost-plus pharmacies or checking your insurer's Tier 1 preferred list prevents pharmacy counter sticker shock ^[4].

Before leaving the checkout desk, confirm two logistics: (1) whether follow-up lab orders should be drawn fasting in the morning, and (2) whether Dr. Gerstenfeld reviews incoming lab results via the patient portal or requires a scheduled follow-up visit (CPT 99213/99214).
