GreatDoc™ Rating
Proprietary DotMD™ J3 Model Verdict

The Proprietary DotMD™ J3 Model gives Dr. Wahrenberger a strong GreatDoc™™ Rating. It rests on his 4.9★ Google profile (19 reviews), his 95.65th percentile NH CMS volume (3966 Medicare beneficiaries/yr), and his depth in coronary disease, atrial fibrillation, and pacemaker and angioplasty care. We trimmed the score slightly because public review counts are very sparse and include one critical bedside-manner comment, so the ratings are less stable than the clinical record.

The 15-Second Insurance Verification Script (Read This When Calling the clinic front desk)

“Hi, I’m scheduling a new consultation with Dr. Jon Wahrenberger (NPI #1356388037). 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?”

1. Your 10-Second Opening Script (Read Verbatim Before the 11-Second Interruption)

"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)?"

2. In-Office Medicare CPT Procedures to Verify Before Booking
CPT 76536 In-Office High-Resolution Thyroid & Neck Ultrasound

Confirms the endocrinologist images thyroid nodules themselves rather than sending you to a hospital radiology department.

CPT 60100 Ultrasound-Guided Fine-Needle Aspiration (FNA) Biopsy

Identifies structural thyroid specialists vs. general diabetes-only clinics.

3. Exact Blood & Diagnostic Labs to Request on Your Order Sheet
  • ✓ 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)
4. Day-1 Pre-Appointment Rule

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.

  • Before your first visit, confirm that your insurance and any referral requirements cover Dartmouth Health cardiology. Bring recent ECGs, echocardiograms, labs, imaging, and a current medication list so tests are not repeated.

01

What is Dr. Wahrenberger's clinical practice focus and patient volume in Lebanon, NH?

The Short Answer

Federal CMS Medicare Part B records show Dr. Wahrenberger treats 3,966 unique Medicare beneficiaries and performs 5,622 clinical services per year—ranking in the 96th percentile across NH [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 Medical Center DR, Lebanon, NH 03756. Maintaining a 96th-percentile statewide volume means Dr. Wahrenberger's clinic manages high-complexity Cardiology cases every week rather than occasional referrals [1][2].

Before Your Visit

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.

02

Does Dr. Wahrenberger accept Original Medicare Part B assignment and major commercial PPO plans?

The Short Answer

Dr. Wahrenberger is registered in the federal CMS NPPES & PECOS system under NPI #1356388037 in Lebanon, NH, actively treating 3,966 Medicare Part B beneficiaries per year [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 1 Medical Center DR, 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].

Before Your Visit

Give the reception desk Dr. Wahrenberger's 10-digit NPI (#1356388037) when calling your insurer's Member Services line to verify in-network tier status in 60 seconds.

03

How did Dr. Jon Wahrenberger, MD earn a 4.7 ★ GreatDoc™ Rating (92/100)?

The Short Answer

The Proprietary DotMD™ J3 Model gives Dr. Wahrenberger a strong GreatDoc™™ Rating. It rests on his 4.9★ Google profile (19 reviews), his 95.65th percentile NH CMS volume (3966 Medicare beneficiaries/yr), and his depth in coronary disease, atrial fibrillation, and pacemaker and angioplasty care. We trimmed the score slightly because public review counts are very sparse and include one critical bedside-manner comment, so the ratings are less stable than the clinical record.

The Proprietary DotMD™ J3 Model evaluates practicing U.S. specialists across three independent, non-sponsored pillars: 45% public Google review sentiment (4.9 ★ across 19 reviews), 35% federal CMS Medicare Part B procedure volume (96th percentile in NH), 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 #1356388037) and verified patient feedback.

Before Your Visit

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.

04

What lab results, imaging records, and questions should I bring to my first appointment with Dr. Wahrenberger?

The Short Answer

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 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. Wahrenberger 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.

Before Your Visit

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.

05

How can I avoid overpaying at the pharmacy when Dr. Wahrenberger prescribes a new medication?

The Short Answer

Before leaving the exam room at 1 Medical Center DR, ask Dr. Wahrenberger 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. Wahrenberger 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 Your Visit

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.

06

Where is Dr. Wahrenberger's office located in Lebanon, and how should I plan arrival and follow-up?

The Short Answer

Dr. Wahrenberger practices at 1 Medical Center DR, Lebanon, NH 03756. 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. Wahrenberger reviews incoming lab results via the patient portal or requires a scheduled follow-up visit (CPT 99213/99214).

Before Your Visit

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.
