Most doctors spend 10+ years training for clinical excellence. Nobody trains them for what comes next — the LLC, the bank accounts, the insurance contracts, the EMR systems, the billing teams. Opening a medical practice is equal parts clinical preparation and business execution, and the business side is where most new practices stumble. This guide covers every step of opening a medical practice, based on 20 years of helping independent physicians build from scratch.
Step 1 — The Legal Foundation
Everything starts with your legal entity. You need to register an LLC, PLLC, or S-Corp depending on your state, specialty, and long-term tax strategy. Most physician-owned practices begin as a PLLC (Professional Limited Liability Company), which provides both liability protection and pass-through taxation. Your healthcare attorney should draft an operating agreement that covers ownership structure, profit distribution, and decision-making authority — especially if you have partners.
Asset protection starts here, not after you are successful. Many physicians wait until they have significant revenue to think about protecting personal assets from malpractice or business liability. That is backwards. Trust formations, proper entity structuring, and insurance should all be established before you see your first patient. The cost of doing this right from day one is a fraction of the cost of doing it wrong later.
REL1EF walks physicians through every step of entity formation and legal setup as part of our Practice Launch service — from choosing the right structure to filing with the state.
Step 2 — Financial Setup
Once your entity is formed, open a dedicated business bank account immediately. Never commingle personal and business funds — it undermines your liability protection and makes accounting a nightmare. Set up QuickBooks or an equivalent accounting system from day one so that every dollar in and out is tracked from the start.
Understand your startup cost categories before you spend anything. Equipment, staffing, licensing, malpractice insurance, lease deposits, EMR licensing, and marketing all need to be budgeted. Most new practices underestimate startup costs by 30 to 50 percent. REL1EF helps with financial modeling before the first dollar is spent — building out realistic cash flow projections so you know exactly how much runway you need and when you can expect to break even.
Step 3 — Finding Your Location
Your location decision affects everything from patient volume to payer mix. Leasing is the most common path for new practices — it preserves capital and provides flexibility. Before signing a lease, verify zoning compliance, check health department requirements, and get realistic renovation timelines. A space that looks move-in ready can still require months of buildout for exam rooms, ADA compliance, and medical waste systems.
If your practice involves surgical procedures, the calculus changes entirely. Ambulatory surgery center development has its own regulatory, licensing, and construction requirements that run on a longer timeline. REL1EF provides full ASC development support for practices that need surgical facility planning alongside their practice launch.
Step 4 — Credentialing and Licensing
Credentialing is the process that allows you to bill insurance companies. It is also the single biggest bottleneck for new practices. You need two NPI numbers — a Type 1 (individual provider) and a Type 2 (organization/practice). You also need your state medical license, DEA registration, and any specialty-specific certifications.
Medicare enrollment alone takes 90 to 180 days. Commercial payer credentialing varies by carrier but typically runs 60 to 120 days. The critical mistake most new physicians make is waiting until the office is ready to start credentialing. By then, you have a fully built practice with no ability to bill for services.
Pro Tip
Start credentialing at least six months before you plan to see your first patient. File your Medicare application the same week you register your LLC. Submit commercial payer applications as soon as you have your NPI and tax ID. Credentialing is a slow, bureaucratic process and there is no way to rush it — you can only start early.
Step 5 — Setting Up Your Billing System
Your billing infrastructure needs to be operational before your first patient walks in. This means selecting an EMR system, connecting to a clearinghouse, and deciding whether to handle billing in-house or outsource it. The EMR decision is one you will live with for years, so evaluate based on specialty fit, payer integration, reporting capabilities, and workflow — not just price.
The cost comparison between in-house and outsourced billing is significant. A single full-time billing specialist costs a minimum of $52,000 per year in salary alone — before benefits, training, software licenses, and management overhead. REL1EF's revenue cycle management runs at 6% of collections with no salary, no benefits, and no downtime. For a new practice that does not yet have the volume to justify a full-time hire, outsourced billing is almost always the smarter financial move.
Step 6 — Insurance Contracts
Credentialing and contracting are related but different. Credentialing gets you recognized by the payer. Contracting determines your reimbursement rates. Many new physicians sign the first contract offered by a payer without negotiating, locking themselves into rates that may be 20 to 40 percent below what they could have gotten with proper leverage.
The in-network versus out-of-network decision is one of the most important financial decisions you will make. Going in-network provides patient volume and predictable cash flow but caps your reimbursement. Staying out of network means fewer guaranteed patients but dramatically higher per-claim revenue — OON providers routinely collect 4 to 6 times Medicare rates on the same procedures that in-network providers are reimbursed at 1 to 1.5 times Medicare.
For specialties like emergency medicine, anesthesia, and surgery where patients do not choose their provider, the OON model can generate significantly more revenue with the right billing partner. Learn more about how this works in our out-of-network billing overview.
Step 7 — Clinical Operations Setup
With your billing system, credentialing, and contracts in place, it is time to build out clinical workflows. This includes documentation templates that support proper coding, EMR workflow configuration for your specific specialty, insurance eligibility verification processes, and a scheduling system that matches your capacity.
Every clinical workflow should be designed with billing in mind. The documentation your providers create is the foundation of every claim you submit. If templates are incomplete, notes lack medical necessity language, or coding is inconsistent, you will see higher denial rates and slower collections from day one. Build it right before you open the doors.
Step 8 — Your Revenue Cycle from Day One
Your revenue cycle starts the moment your first patient checks in. From that point, every step matters — eligibility verification, charge capture, claim submission, payment posting, denial management, and patient collections. The target for new practices should be a clean claim rate of 98% or higher, meaning 98 out of every 100 claims are accepted by the payer on first submission without errors.
Denial handling is where most new practices fall behind. Without a system for tracking denials by reason code, filing timely appeals, and correcting root causes, accounts receivable aging becomes a runaway problem. Claims over 90 days old are exponentially harder to collect. The practices that maintain healthy cash flow are the ones that address every denial within 48 hours and never let A/R age past 60 days without intervention.

The Full Launch Timeline
Here is a realistic six-month timeline for launching a medical practice from scratch. Every practice is different, but this sequence ensures that nothing falls through the cracks.
Month 1–2: Foundation
Month 3–4: Build-Out
Month 5–6: Launch
The Mistake Most New Practices Make
The most common and most expensive mistake new practices make is seeing patients before the billing system is fully operational. The physician is eager to start generating revenue, the office looks ready, and patients are waiting — so they open the doors. But claims go out with errors, denials pile up, credentialing is incomplete for half the payers, and within 60 days there is a growing mountain of unbilled or underpaid claims that nobody has time to fix.
Build the back office before the front door opens. Your billing system, credentialing, contracts, and workflows should all be tested and confirmed working before your first appointment. The practices that launch cleanly are the ones that resist the urge to rush. Two extra weeks of preparation can prevent six months of revenue cycle problems.
