Original Medicare (Part B) + Medigap Supplement
✓ Verified Participating (Accepts Assignment)Federal CMS Part B records verify NPI #1972586964 treats 3,247 Medicare beneficiaries/yr and accepts Medicare-approved allowable fees (80% Medicare + 20% Medigap after annual Part B deductible).
Anthem Blue Cross Blue Shield
✓ Major PPO Plans AcceptedEmployer and individual PPO plans are widely accepted. Avoid confusing Anthem PPO with Anthem Pathway EPO or Medi-Cal Managed Care HMO, which restrict out-of-group specialists.
Blue Cross Blue Shield (BCBS National BlueCard)
✓ PPO & BlueCard AcceptedIf you have Blue Shield Trio HMO or Access+ HMO, you must first obtain an authorized specialist referral from your assigned Primary Care Medical Group (IPA).
Aetna (CVS Health)
✓ Open Choice PPO & POS IIConfirm your specific employer group network ID on the back of your Aetna card when scheduling.

Kaiser Permanente, Commercial HMOs & Medi-Cal / Medicaid
⚠ Out-of-Network / Auth RequiredClosed-panel HMOs (like Kaiser Permanente) and narrow-network EPO/Medi-Cal plans generally do not cover independent Beverly Hills private-practice specialists unless you pay cash or obtain a formal gap-exception authorization.
“Hi, I’m scheduling a new consultation with Dr. William Whang (NPI #1972586964). Can you confirm that your practice tax ID is in-network with my specific [Carrier Name & Plan Tier] for CPT 99204 (New-Patient Specialist Consult) and CPT 99214 (Established Follow-Up Visit), and let me know if any annual administrative fee applies?”
Walk Into Your 15-Minute Appointment With Exact Labs, CPT Codes & Opening Words
Clinicians interrupt patients after a median of 11 seconds (J Gen Intern Med, PMID 29972200). Select your appointment reason below to generate your 1-page script:
Hypothyroidism, Subclinical TSH Drift (2.5–8.0 mIU/L) or Thyroid Nodule
"I have two specific goals for our 15 minutes today: first, my morning TSH is [X] mIU/L with persistent fatigue and cold intolerance, so I would like to evaluate Free T4, Free T3, TPO Antibodies, and Ferritin together; second, if we palpate any thyroid asymmetry, can we perform an in-office neck ultrasound (CPT 76536)?"
Confirms the endocrinologist images thyroid nodules themselves rather than sending you to a hospital radiology department.
Identifies structural thyroid specialists vs. general diabetes-only clinics.
- ✓ TSH + Free T4 + Free T3 (drawn before 8:30 AM fasting)
- ✓ Thyroid Peroxidase (TPO) & Thyroglobulin Antibodies (Hashimoto rule-out)
- ✓ Serum Ferritin + Vitamin D 25(OH)D (required for T4-to-T3 deiodinase conversion)
Hold all Biotin (Vitamin B7) supplements for 72 hours before your blood draw so streptavidin assay interference does not create a false TSH/Free T4 reading.
Prediabetes (HbA1c 5.7%–6.4%), Type 2 Diabetes or Insulin Resistance
"My recent HbA1c came back at [X]%. Today I want to check my Fasting Insulin to calculate HOMA-IR, discuss starting Extended-Release Metformin ER ($5.40/mo cash) or a 14-day Continuous Glucose Monitor trial (CPT 95251), and establish a 90-day re-test target below 5.4%."
Verifies the clinic actively prescribes and interprets Dexcom/Libre CGM sensor data.
Standard outpatient evaluation code; ask for transparent self-pay rates ($120–$180) if uninsured.
- ✓ HbA1c + Fasting Plasma Glucose + Fasting Serum Insulin (HOMA-IR)
- ✓ Comprehensive Metabolic Panel (eGFR + ALT/AST liver enzymes for fatty liver check)
- ✓ Urine Albumin-to-Creatinine Ratio (uACR) + Annual Serum Vitamin B12 (if on Metformin)
Bring a 3-day log of post-dinner fingerstick or CGM readings and confirm whether your pharmacy filled Metformin ER (Extended-Release) rather than immediate-release.
Stage 1–2 Hypertension (≥ 130/80 mmHg) or Elevated LDL-C / ApoB / Lp(a)
"My 7-day rested home blood pressure averages [X/Y] mmHg and my LDL-C is [Z] mg/dL. Today I would like to review my home cuff log against office white-coat readings, order direct Apolipoprotein B (ApoB) and one-time genetic Lipoprotein(a), and decide if a CAC score or low-dose statin/ARB is warranted."
Assesses left ventricular wall thickness and valve function directly in the cardiology suite.
Baseline rhythm and conduction screen prior to antihypertensive titration.
- ✓ Direct Apolipoprotein B (ApoB target < 80 mg/dL) + One-Time Lipoprotein(a) [Lp(a) in nmol/L]
- ✓ High-Sensitivity C-Reactive Protein (hs-CRP < 1.0 mg/L)
- ✓ Basic Metabolic Panel (Serum Potassium + eGFR 2–4 weeks after starting Lisinopril/Losartan)
Bring your physical home upper-arm BP cuff to the clinic to validate calibration, along with a 7-day written morning/evening seated average.
Unexplained Fatigue, Restless Legs or Hair Shedding with "Normal" Ferritin (15–35 ng/mL)
"Even though my hemoglobin is normal, my Serum Ferritin is [X] ng/mL and I am experiencing persistent fatigue and hair shedding. Can we check a fasting Iron Panel with Transferrin Saturation (TSAT), rule out celiac/GI malabsorption, and target a Ferritin above 50–75 ng/mL?"
Confirms the hematology clinic can administer IV iron when oral iron fails or causes GI distress.
Tracks mean corpuscular volume (MCV) and early reticulocyte hemoglobin response.
- ✓ Serum Ferritin + Fasting Serum Iron + TIBC + Transferrin Saturation (TSAT %)
- ✓ Reticulocyte Hemoglobin Content (CHr) + Complete Blood Count (CBC)
- ✓ Vitamin B12 + Methylmalonic Acid (MMA) + Folate + Tissue Transglutaminase IgA (Celiac screen)
Stop oral iron supplements for 24 hours before drawing a fasting morning Serum Iron and TSAT panel so circulating pill iron does not skew saturation.
Chronic Acid Reflux (GERD), IBS Bloating, Iron Loss or Screening Colonoscopy
"I have had [reflux / bloating / unexplained low ferritin] for [X] months. Today I want to distinguish upper GI mucosal issues from functional motility, review a step-down plan so I am not stuck on a PPI indefinitely, and verify whether you perform diagnostic EGD (CPT 43239) or colonoscopy (CPT 45385) at an ambulatory center."
High annual CPT 45385 volume (>300/yr) correlates with higher adenoma detection rates and safer polypectomy.
Rules out Barrett esophagus, H. pylori gastritis, and duodenal celiac villous atrophy.
- ✓ H. pylori Stool Antigen or Urea Breath Test (must be off PPIs for 14 days prior)
- ✓ Fecal Calprotectin + Fecal Occult Blood (distinguishes IBD inflammation from IBS)
- ✓ Celiac Serology (tTG-IgA + Total Serum IgA while still eating gluten)
Always request an Ambulatory Surgery Center (ASC) facility quote rather than a hospital outpatient department (HOPD) for endoscopy/colonoscopy to save $1,200–$2,400 in facility fees.
What Real Patients Praise vs. Watch Out For
- **Clear, thorough explanations:** Patients repeatedly say he explains complex arrhythmia diagnoses and treatment options in understandable terms, and that he shows real concern for them.
- **High-volume electrophysiology expertise:** He treats 3,247 Medicare patients a year, ranks in the 91.67th city percentile, and has a strong record with complex AFib ablation, device implantation and LAA closure.
- **Welcoming, coordinated care:** Patients describe feeling at home with his team and report smooth coordination and successful outcomes at Mount Sinai.
- As a high-volume specialist at a large academic center, he may have longer waits for new-patient appointments, so book early and ask to be placed on a cancellation list.
- Bring recent ECGs, Holter or monitor reports, echocardiograms and a medication list. Confirm your insurance and any referral or prior-authorization requirements for ablation or device procedures before your visit.

Federal CMS Medicare Part B records show Dr. Whang treats 3,247 unique Medicare beneficiaries and performs 7,749 clinical services per year—ranking in the 91th percentile across NY [1][2].
Annual CMS Part B utilization data tracks every office consultation (CPT 99204/99214), diagnostic evaluation, and therapeutic procedure billed for Medicare beneficiaries at 1 Gustave L Levy Pl, New York, NY 10029. Maintaining a 91th-percentile statewide volume means Dr. Whang's clinic manages high-complexity Clinical Cardiac Electrophysiology cases every week rather than occasional referrals [1][2].
Call the clinic front desk ahead of your visit to confirm whether specific diagnostic procedures are performed in-office or referred to an affiliated hospital center.
Does Dr. Whang accept Original Medicare Part B assignment and major commercial PPO plans?
Dr. Whang is registered in the federal CMS NPPES & PECOS system under NPI #1972586964 in New York, NY, actively treating 3,247 Medicare Part B beneficiaries per year [1][2].
Original Medicare Part B covers 80% of the Medicare-approved amount for participating Clinical Cardiac Electrophysiology 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 1 Gustave L Levy Pl, 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].

How did Dr. William Whang, MD earn a 4.9 ★ GreatDoc™ Rating (96/100)?
The Proprietary DotMD™ J3 Model rates Dr. Whang 4.9★ because of his 5.0★ Google profile (a small sample of 3 reviews, backed by 5.0 on U.S. News across 92 reviews and 4.9 across 300+ Mount Sinai ratings) and his 90.65th percentile NY CMS volume (3,247 Medicare beneficiaries/yr). His standing as an elite expert in atrial fibrillation, catheter ablation, pacemakers/ICDs and left atrial appendage closure supports the high clinical-confidence score.
The Proprietary DotMD™ J3 Model evaluates practicing U.S. specialists across three independent, non-sponsored pillars: 45% public Google review sentiment (5.0 ★ across 3 reviews), 35% federal CMS Medicare Part B procedure volume (91th percentile in NY), 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 #1972586964) and verified patient feedback.
Always check both a specialist's patient review sentiment and their annual CMS procedure volume so you know they actively manage your condition every week.
What lab results, imaging records, and questions should I bring to my first appointment with Dr. Whang?
Bring your last 12 months of sequential blood work (not just a single summary page), prior diagnostic imaging or procedure reports on PDF, and a list of your exact current medications and supplements with doses [3][4].
Because a new-patient Clinical Cardiac Electrophysiology 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. Whang 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.
Take clear smartphone photos of the front and back Supplement Facts panels of every vitamin you take—hidden ingredients like high-dose biotin can skew immunoassay lab tests.
How can I avoid overpaying at the pharmacy when Dr. Whang prescribes a new medication?
Before leaving the exam room at 1 Gustave L Levy Pl, ask Dr. Whang whether a generic first-line option exists and check its federal CMS NADAC wholesale acquisition cost on dotMD [4].
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. Whang 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].
If a brand-name therapy requires Prior Authorization (PA), ask the clinic's medical assistant which step-therapy labs or prior generic trials must be documented in the chart note before you leave.
Where is Dr. Whang's office located in New York, and how should I plan arrival and follow-up?
Dr. Whang practices at 1 Gustave L Levy Pl, New York, NY 10029. Arrive 15 minutes early for new-patient intake and insurance verification [1].
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. Whang reviews incoming lab results via the patient portal or requires a scheduled follow-up visit (CPT 99213/99214).
Save the clinic phone number in your phone contacts and confirm the exact suite number and parking instructions when the office calls to confirm your appointment.
