Physician-Led Longevity, Prevention & Complex Chronic Care

Healthcare should answer exclusively to the patient, not to pharmacy middlemen or insurance quotas. At Fishtown Medicine, Dr. Ashvin Vijayakumar MD (Dr. Ash) delivers unhurried, evidence-based primary care built on a radical principle: 100% transparent pass-through pricing with zero markups across the board.

What does “Zero-Markup Care” actually mean?

We pass through every single clinical tool at our direct wholesale cost. We refuse to participate in the hidden kickbacks, pharmacy spreads, and retail markups that plague modern healthcare.

Prescriptions

Cost Plus Wholesale

We route eligible generic medications directly to Mark Cuban Cost Plus Drugs. Patients pay true transparent cost with zero practice markup and zero pharmacy spread.

$0 Practice Surcharge
Diagnostic Labs

Quest Direct Pass-Through

Advanced biomarkers (ApoB, fasting insulin, Lp(a), metabolic panels) are passed through at our negotiated Quest wholesale rates. Panels billed at $1,500+ by hospital networks often cost $35 to $65.

$0 Lab Markup
Clinical Protocols

Fullscript Direct Pass-Through

Clinical-grade supportive therapeutics through Fullscript are passed along with zero retail profit margin. Every recommendation is chosen purely because it works.

$0 Retail Margin

The Fiduciary Standard:You pay a flat, transparent membership fee solely for Dr. Ash’s diagnostic reasoning, time, and longitudinal care. Because we never profit from tests, pills, or supplements, our incentives are 100% aligned with saving your money and protecting your health.

What clinical areas does Dr. Ash focus on?

Our practice focuses on two core clinical disciplines: proactive longevity medicine and methodical care for complex multisystem illness.

Discipline 01

Longevity Medicine & Healthspan

The best time to address vascular and metabolic drift is 20 years before an acute event. We look closely at optimal physiological thresholds rather than population averages:

  • Early ApoB, Lp(a), and endothelial vascular protection
  • Metabolic flexibility, fasting insulin, and visceral adiposity
  • Cardiorespiratory fitness, VO2 max optimization, and sleep architecture
  • Cognitive reserve protection for the 85-year-old version of yourself
Discipline 02

Complex Multisystem Chronic Illness

For patients who have navigated fragmented 12-minute specialist visits with labs marked “normal” despite profound, persistent daily symptoms:

  • Mast Cell Activation Syndrome (MCAS) and histamine overload
  • Dysautonomia, POTS, and orthostatic intolerance
  • Post-viral fatigue and multisystem immune dysregulation
  • Subtle thyroid, neuroendocrine, and metabolic shifts

How does our prescribing integrate with Cost Plus?

Our electronic health record and Photon prescribing workflows are pre-configured for direct transmission to Mark Cuban Cost Plus Drugs.

Surescripts Direct eRx

Direct electronic transmission to NCPDP 5755167 (Lakeland / HealthDyne hub), bypassing manual paper faxes and telephone calls.

Automated Email Directives

Orders automatically pass the verified patient email address into pharmacy notes to enable 24-hour digital account matching.

Licensed in 40 States

Dr. Ash holds active, unrestricted medical licenses across 40 states, providing legal virtual care coverage nationwide.

Strict Zero Opioids

100% compliant with Cost Plus non-controlled inventory rules. Practice policy strictly prohibits prescribing opioids or controlled substances.

Optimized 180-Day Supplies

For stable chronic maintenance, scripts are written as 180 days with 1 refill, halving annual dispensing and delivery fees for patients.

Legitimate Fiduciary Care

Full 60 to 90 minute evaluations and deep chart syntheses. We practice longitudinal medicine, not transactional pill mill scripts.

How does ongoing care work at Fishtown Medicine?

Because deep clinical thinking and lasting health take time, care at Fishtown Medicine is structured as an ongoing, longitudinal partnership rather than a rushed transaction.

Our members receive direct cell phone access to Dr. Ash, unhurried 60 to 90 minute appointments, methodical medical project management across prior records, and continuous optimization. We only answer to our patients, ensuring our time is dedicated entirely to thoughtful, high-touch medicine.

How does a transparent membership pay for itself?

When hospital networks bill insurance deductibles for routine care, patients routinely pay hidden markups that dwarf direct practice fees.

The Traditional Middleman Pipeline
  • · Full-panel advanced labs billed to deductible: $1,500 - $3,000/yr
  • · Maintenance generic prescriptions at retail cash: $400 - $900/yr
  • · Functional medicine supplement markups: $500 - $1,000/yr
  • · Total out-of-pocket middleman costs: $2,400 - $4,900/yr

  • · 180-day supplies via Cost Plus Drugs: ~$60 - $100/yr
