How to Start a Private Medical Practice in the US: Complete Guide for Physicians in 2026

The United States has the largest private medical market in the world. Unlike the UK or Europe, there is no single national health system — private practice is the default model for most US physicians outside of academic medicine and large health systems. But the landscape of private practice is changing fast. Rising administrative burdens, insurer pressures, and burnout have driven many physicians out of independent practice — while at the same time, models like concierge medicine and Direct Primary Care (DPC) are seeing explosive growth as physicians reclaim control over how they practise.

This guide covers how to start a private medical practice in the US in 2026: the legal and regulatory requirements, the business structure decisions, the practice model choices, the insurance and credentialing process, and how AI automation is helping new private practitioners build professional, efficient practices from day one.

Private Practice Models in the US: Choosing Your Path

Before anything else, you need to decide what kind of private practice you are building. In the US, the main models are:

Fee-for-Service Independent Practice

The traditional model. You see patients, bill their insurance (Medicare, Medicaid, commercial insurers), and collect payment through the insurance billing cycle. You need to credentialling with each insurer, maintain a billing infrastructure, and manage prior authorizations and denials. High volume is typically required to cover overhead. Revenue is predictable but margins are thin and administrative burden is high.

Concierge Medicine

Patients pay an annual or monthly membership fee (typically $1,500–$3,000 per year or $150–$300 per month) for enhanced access — same or next-day appointments, direct physician phone and text access, longer appointment times, and proactive preventive care. The physician maintains a smaller panel (usually 300–600 patients versus 2,000+ in traditional primary care) and may or may not bill insurance separately for services. Growing rapidly: the concierge medicine market in the US is projected to exceed $10 billion by 2027.

Direct Primary Care (DPC)

Similar to concierge in structure — monthly membership fee, small patient panel — but typically positioned at a lower price point ($50–$150 per month) and explicitly does not bill insurance for primary care services. Patients use insurance only for specialist care, hospitalisation, and catastrophic events. DPC practices typically pair with high-deductible health plans or health share ministries. Over 2,000 DPC practices now operate across the US, a number that has doubled since 2020.

Specialty Private Practice

Specialists — dermatology, psychiatry, orthopaedics, gastroenterology, ophthalmology, and others — operate independent specialty practices that may be fee-for-service, cash-pay, or hybrid. Cash-pay specialty practices are growing particularly fast in areas like psychiatry (mental health parity and insurer network gaps), dermatology (cosmetic services), and musculoskeletal medicine.

Step 1: Legal Business Structure

The legal structure of your practice determines your liability, tax treatment, and operational requirements. The main options:

Professional Corporation (PC) or Professional Limited Liability Company (PLLC)

Most US states require physicians to operate through a professional corporation (PC) or professional LLC (PLLC) rather than a standard LLC or corporation. The naming and structure requirements vary by state. In most states, only licensed physicians can own shares in a medical PC — this is important if you are considering bringing in investors.

Solo Practice vs Group Practice

Starting solo is the simplest path but comes with the full administrative burden. A group of two or more physicians can share overhead, cover each other’s patients, and split administrative costs. Partnership agreements must be in writing and should cover ownership, buyout provisions, dispute resolution, and what happens if a partner leaves or becomes incapacitated.

Management Service Organisation (MSO)

Some physicians — particularly in states with strict corporate practice of medicine laws — use an MSO structure where a separate management company (which can have non-physician investors) provides administrative services to the physician-owned clinical entity. This is a common structure in private equity-backed practices.

Step 2: State Medical Licensing and Credentialing

State Medical License

You must be licensed in the state where you practise. If you plan to see patients via telehealth in multiple states, you need licensure in each state. The Interstate Medical Licensure Compact (IMLC) expedites multi-state licensing for qualifying physicians — currently available in 40+ states.

DEA Registration

If you prescribe controlled substances, you need a DEA registration for each state in which you practise. The federal DEA registration number is specific to your practice address.

National Provider Identifier (NPI)

Every US physician must have an NPI — a unique 10-digit identification number issued by CMS. You need an individual NPI (Type 1) and your practice needs an organisational NPI (Type 2). Both are obtained at nppes.cms.hhs.gov and are free.

Medicare and Medicaid Enrollment

If you plan to see Medicare or Medicaid patients, you must enroll as a Medicare provider through PECOS (Provider Enrollment, Chain, and Ownership System) and in your state’s Medicaid program. Medicare enrollment can take 60–120 days. Start early.

Commercial Insurance Credentialing

To bill commercial insurers (UnitedHealthcare, Aetna, Cigna, Blue Cross Blue Shield, Humana), you must credential with each payer separately. Credentialing typically takes 90–150 days per payer. Many physicians use a credentialing service to manage this process. Begin credentialing as soon as you have an NPI and practice address — ideally 6–9 months before you plan to open.

Step 3: Malpractice Insurance

Medical malpractice insurance is essential before you see your first patient. The two main types:

Claims-Made Policy

Covers claims made while the policy is active. Cheaper initially but requires ‘tail coverage’ when you leave the policy to cover future claims from incidents that occurred during the covered period. Tail coverage can cost 1.5–2x the annual premium.

Occurrence Policy

Covers any incident that occurred during the policy period, regardless of when the claim is made. More expensive annually but no tail coverage required. Generally preferred for long-term private practice.

Costs vary significantly by specialty, state, and claims history. Primary care physicians typically pay $5,000–$12,000 per year. High-risk specialties (OB/GYN, neurosurgery, orthopaedic surgery) can pay $50,000–$150,000+ per year in high-risk states.

Step 4: Practice Management Infrastructure

Electronic Health Record (EHR)

An EHR is required for Medicare and Medicaid participation and is essential for any serious practice. Popular options for independent practices include Athenahealth, DrChrono, eClinicalWorks, Kareo, and Jane App. For DPC practices, purpose-built platforms like Hint Health and Elation Health are widely used. Cost: $200–$700 per physician per month for most platforms.

Practice Management System

Handles scheduling, billing, insurance verification, and claims management. Often bundled with the EHR. Standalone options include Kareo and CollaborateMD.

Medical Billing

In-house billing requires a trained billing team and ongoing education as insurer requirements change. Outsourced medical billing typically costs 4–8% of collections. For new practices, outsourcing billing is strongly recommended — credentialing and billing complexity will overwhelm a solo or small practice if managed internally from the start.

Step 5: Physical Setup

Office Space

Medical office space in the US typically costs $25–$60+ per square foot per year depending on market. A basic single-physician office of 1,000–1,500 sq ft runs $25,000–$90,000+ annually in rent. Some physicians begin in shared medical office space or subleasing from an established practice to reduce initial overhead.

Equipment

Examination table, diagnostic equipment, office technology, and any specialty-specific equipment. Budget $20,000–$50,000 for a basic primary care setup. Specialty equipment adds significantly.

Staff

A minimum solo practice setup typically includes a medical assistant (MA) and either a front desk person or a medical receptionist. Staff costs including benefits run $45,000–$75,000 per employee per year in most US markets. Telehealth-first practices can launch with lower staffing.

Step 6: AI Automation for US Private Physicians

US private practice physicians are increasingly deploying AI voice agents and automation systems to manage the administrative load that would otherwise require additional staff or consume physician time.

AI receptionist for 24/7 call answering

Patients call at all hours. For concierge and DPC practices that promise enhanced access, missing after-hours calls is a direct violation of the practice’s value proposition. For fee-for-service practices, every missed call is a patient who books with a competitor. An AI voice receptionist answers every call immediately — nights, weekends, and during clinic sessions — with HIPAA-compliant call handling and live calendar booking.

AI appointment scheduling and confirmation

The AI integrates with your EHR or scheduling system, checks live availability, and confirms appointments in real time during the call. It also runs outbound confirmation calls 24–48 hours before appointments, reducing no-show rates by 25–40%. For a physician billing $300 per appointment with a 12% no-show rate on a 30-appointment week, a 35% reduction in no-shows recovers $37,800 per year in revenue.

Patient intake and FAQ handling

The AI collects new patient intake information — insurance details, reason for visit, prior medical history summary, referring physician — before the appointment. It answers FAQ calls: Do you accept Blue Cross? What is the membership fee? How do I transfer my records? What should I bring? All handled without staff involvement.

HIPAA compliance

Any AI system handling protected health information (PHI) for a US medical practice must operate under a signed Business Associate Agreement (BAA) with the vendor and comply with HIPAA requirements including data encryption, access controls, and audit logging. AIMamoth provides signed BAAs and HIPAA-compliant data handling for all US healthcare deployments.

Frequently Asked Questions

How long does it take to open a private medical practice in the US?

From decision to first patient, most physicians need 6–12 months. The longest lead time items are insurance credentialing (90–150 days per payer), Medicare enrollment (60–120 days), and state licensing for physicians moving to a new state. Concierge and DPC practices that do not bill insurance can launch faster — sometimes within 60–90 days of beginning setup.

What is the difference between concierge medicine and Direct Primary Care?

Both use a membership model with a small patient panel and enhanced access. The key difference is insurance billing: concierge practices typically bill insurance for individual services in addition to charging the membership fee. DPC practices do not bill insurance for primary care services — the monthly membership fee covers all primary care. DPC is simpler administratively but requires patients to carry separate coverage for specialist and hospital care.

Do I need to hire a biller or can I do billing myself?

For fee-for-service practices, outsourcing billing to an experienced medical billing company is strongly recommended for the first 1–2 years. Insurer credentialing, claim submission rules, prior authorization requirements, and denial management are complex and change frequently. Billing errors and delays significantly impact cash flow for new practices. DPC practices that do not bill insurance avoid this complexity entirely.

Can AI handle patient calls for my private practice and be HIPAA compliant?

Yes, with a properly configured system and a signed Business Associate Agreement. AIMamoth deploys HIPAA-compliant AI voice receptionists for US private physician practices with BAA documentation, encrypted call handling, and audit-ready logs. The AI does not share or store PHI in ways that violate HIPAA — it collects scheduling and administrative information only, and clinical information is routed to your EHR through compliant channels.
