Legal & Compliance

Your legal entity is the foundation on which everything else is built. It affects your liability exposure, your tax treatment, your ability to add partners, and your options when you eventually want to grow or exit. Getting this right at the beginning is significantly easier than correcting it later.

Most physicians will choose between an LLC or PLLC, a Professional Corporation, or an LLP depending on their state’s requirements and practice goals. Each has distinct implications for liability, taxation, and flexibility.

Entity type comparison

S-Corp tax election

An LLC can elect to be taxed as an S-Corporation by filing IRS Form 2553. For profitable practices, this can produce meaningful tax savings by allowing the physician-owner to take a reasonable salary — subject to self-employment tax — and distribute remaining profits without that tax applying. The IRS scrutinizes S-Corp arrangements closely; the salary must be defensible for your specialty and market. Consult a CPA with medical practice experience before making this election.

State-specific requirements

States vary significantly in what they permit or require for physician practice entities. Some mandate Professional Corporations; others require PLLCs for licensed professionals. Your state medical board website is the authoritative source. Do not rely on general business formation resources for this — the requirements for physician practices are distinct.

Corporate Practice of Medicine (CPOM)

Most states prohibit non-physicians from owning or controlling a medical practice. This becomes particularly relevant if your practice involves non-physician investors or business partners. In those situations, a Management Services Organization (MSO) structure is the standard legal solution — but it requires careful design by a healthcare attorney. If non-physician ownership is part of your plan, seek specialized legal counsel before finalizing your entity structure.

Solo practice considerations

For solo practitioners, the LLC or PLLC is the most common and flexible choice, with the option to elect S-Corp tax treatment once the practice reaches sufficient profitability. Even as a single-member entity, a properly drafted operating agreement is essential — it establishes the separation between personal and business affairs that protects your liability shield.

Small partnership considerations

This guidance is scoped for small practices, typically solo to three partners, though the principles apply to larger practices as well. If entering practice with one or more partners, several agreements must be in place before you see your first patient:

• Partnership or operating agreement — governance, voting rights, decision-making authority, profit and loss distribution
• Buy-sell agreement — what happens when a partner wants to exit, becomes disabled, dies, or is asked to leave
• Compensation structure — how physician compensation is calculated and adjusted over time
• Non-compete and non-solicitation provisions — understand what you are agreeing to before signing

These conversations are uncomfortable to have before the practice opens. They are significantly more expensive to have in a courtroom after it does.

Before you see your first patient, several registrations must be in place. Some have processing times long enough to affect your opening date if not started early. Begin these in parallel with entity formation, not after it.

State medical license

Your medical license must be active in every state where you see patients — including telehealth patients. If you plan to practice across multiple states, the Interstate Medical Licensure Compact (IMLC) can significantly expedite multi-state licensing for eligible physicians. Not all physicians qualify; verify your eligibility at imlcc.org before assuming this pathway is available to you.

DEA registration

Required if you intend to prescribe controlled substances. A separate DEA number is required for each state where you practice and for each physical practice location. Use your practice address — the DEA can and does inspect registered locations. Do not use a home address.

National Provider Identifier (NPI)

Your NPI is a unique 10-digit identifier required for all HIPAA-covered transactions. You need two: a Type 1 NPI as an individual physician, and a Type 2 NPI for your practice entity. The Type 2 NPI cannot be applied for until your entity is legally established and your EIN is in hand. Apply at nppes.cms.hhs.gov.

State controlled substance registration

Many states require a separate controlled substance registration in addition to your DEA number. Requirements and processing times vary significantly. Check with your state medical board or pharmacy board early — this is a commonly missed step that can delay prescribing authority.

State entity registration with medical board

Your practice entity may need to register separately with the state medical board, in addition to the Secretary of State filing completed during business formation. Requirements vary by state and entity type. Verify this requirement for your specific state before assuming formation documents alone are sufficient.

Processing time reference

HIPAA is not a checklist — it is a federal compliance framework with significant financial and legal consequences. The average cost of a data breach for a small medical practice is $150,000–$500,000, encompassing breach notification, OCR investigation response, legal fees, and reputational damage. OCR levied over $135 million in fines in 2023 alone. Solo practices and cash-pay practices using EHRs are not exempt — if you transmit health information electronically, you are a covered entity.

The 2024 HIPAA Security Rule updates introduced mandatory technical safeguard requirements that go significantly beyond prior standards — including multi-factor authentication, network segmentation, asset inventory requirements, and incident response testing. If your compliance policies predate 2025, they may no longer meet the standard.

Core compliance requirements

• Designate a Privacy Officer and Security Officer — can be the same person in a small practice
• Conduct a formal Risk Analysis — a specific regulatory requirement under 45 CFR §164.308 with defined elements; a general “risk assessment” is not equivalent
• Develop and maintain written Privacy and Security policies and procedures
• Implement technical safeguards: encryption at rest and in transit, access controls, audit logs, automatic logoff
• Execute Business Associate Agreements with every vendor that handles protected health information — EHR, billing company, AI scribe, cloud storage, communication platforms
• Train all employees within 30 days of hire and annually thereafter; document all training completion
• Develop and test an incident response plan before you need it

Common compliance gaps

• Assuming business versions of consumer tools — Google Workspace, Dropbox, standard Zoom — are automatically HIPAA-compliant; they require specific configuration and a signed BAA
• Failing to obtain BAAs from AI scribe vendors, which handle sensitive clinical audio and notes
• Conducting a generic risk assessment rather than a HIPAA-compliant Risk Analysis with the required elements
• No documented employee training records — the documentation is as important as the training itself in the event of an OCR investigation

Cybersecurity framework for small practices

HHS has published the 405(d) Health Industry Cybersecurity Practices (HICP) framework specifically for small and medium healthcare organizations. It identifies the five most common threats to small practices and provides prioritized, practical mitigation guidance. It is the most accessible starting point for physicians building a cybersecurity program from scratch. Available at 405d.hhs.gov.

By practice model

Adequate insurance is not optional — it is the foundation of practice sustainability. Several policies must be in place before you see your first patient. Others are critical for physicians transitioning from employment, where many coverages were provided automatically and are now your responsibility to arrange independently.

Medical malpractice insurance

Required before seeing your first patient. Your business entity does not shield you from personal malpractice liability. Two policy types exist:

Claims-made: Covers incidents that occur and are reported while the policy is active. Less expensive initially but requires tail coverage when switching carriers or retiring. Tail coverage typically costs 150–300% of your annual premium — a significant expense that must be planned for.

Occurrence: Covers any incident that occurs during the policy period regardless of when it is reported. More expensive upfront but requires no tail coverage. Provides clean protection after retirement or career change.

Premium ranges vary significantly by specialty and state — from approximately $5,000 per year for lower-risk specialties to $50,000 or more per year for surgical or obstetric practices. Verify carrier AM Best ratings; target A or better. Many physician-owned carriers offer free tail coverage after a minimum coverage period of 5–10 years.

Business Owner’s Policy (BOP)

A BOP bundles general liability and commercial property insurance at lower cost than purchasing separately. For a small medical practice, it typically covers slip-and-fall and property damage claims, building contents and equipment, business interruption if you must close due to a covered event, and minor injuries to visitors. Average cost for a small practice runs $110–150 per month.

Cyber liability insurance

Given the frequency and cost of healthcare data breaches, cyber liability insurance is essential. It covers breach notification costs, credit monitoring for affected patients, legal fees and regulatory fines, forensic investigation, and business interruption due to cyberattack. Many carriers now require evidence of basic cybersecurity controls as a condition of coverage. Budget $100–200 per month for a small practice.

Workers compensation

Required by law in most states if you have employees. Covers medical expenses for work-related injuries, lost wages during recovery, and disability benefits. Requirements and carrier options vary by state.

Employment Practices Liability Insurance (EPLI)

Covers claims of discrimination, harassment, and wrongful termination. Increasingly important as practices add staff. Can often be added to a BOP as an endorsement.

Personal coverage — critical for physicians leaving employment

Employed physicians often have the following coverages provided by their employer. Upon leaving employment, these become your personal responsibility:

Disability insurance: Look for a true own-occupation definition that pays full benefits if you cannot practice your specific specialty, even if you could work in another capacity. Pay premiums personally with after-tax dollars so that any benefits received are tax-free. COLA rider and future increase option are worth the added cost.

Health insurance: Options include ACA marketplace plans, association health plans through your specialty society, or a spouse’s employer plan if applicable. Self-employed health insurance premiums are deductible.

Life insurance: If you have taken on business loans, lenders may require life insurance as collateral. In a partnership, life insurance funded buy-sell agreements are the standard mechanism for handling a partner’s death without forcing a disruptive buyout.
