Overview: the road from idea to paid claim

Getting from “I have an idea” to “a payer deposited money in my professional entity’s bank account” takes most new MSO-PC groups four to nine months, and the longest step is almost always payer credentialing, which is largely outside your control. This tutorial walks the whole path in twelve steps.

The running example

Throughout this tutorial we follow Meridian Dermatology, a fictional launch:

Alex Rivera, a non-clinician founder with an operations background, wants to build a dermatology group.
Dr. Priya Shah, a board-certified dermatologist, will be the clinician-owner of the professional entity and will practice there.
They are launching in one state, with one location, and intend to raise institutional capital within two years.

Every step shows what Meridian actually does. Where another vertical would diverge, an industry callout says so.

The five stages

Stage	Steps	What you end up with
Entity	1, 4, 5	A PC and an MSO that legally exist, with EINs
People	3	A clinician-owner who is aligned and properly vetted
Paper	6	An MSA, transfer restrictions, employment agreements, a BAA, an IP license
Payers	7, 9	NPIs, a CAQH profile, and at least one executed payer contract
Pipes	8, 10	Bank accounts that respect the structure, and a billing stack that submits claims

The twelve steps

Pick your state and entity types

Which state you launch in determines your entity form, your CPOM exposure, and your fee structure options. Go →

Find your friendly clinician

The highest-consequence hire in the structure. Go →

Form the PC

Professional purpose clause, licensee attestations, board pre-approvals, EIN. Go →

Form the MSO

A plain LLC or C-corp that will hold the brand, the leases, and the non-clinical team. Go →

Sign the agreement stack

Five documents, in a specific order. Go →

Get NPIs and set up CAQH

Type 1 for the clinician, Type 2 for the PC, and the profile every payer will pull from. Go →

Open bank accounts

Payer money has to land in an account the PC controls. Go →

Enroll with your first payer

One payer, end to end, including the EFT and ERA enrollments that are often missed. Go →

Pick your billing stack

EHR, clearinghouse, and who operates them. Go →

Submit your first claim

A real visit becomes an 837, and acknowledgments come back. Go →

Read your first 835 and get paid

The remittance arrives, the EFT lands, and you post it. Go →

Timeline: how long each step takes

Set this expectation on day one, with yourself and with your investors. Credentialing takes the longest.

Activity	Realistic duration	Can it run in parallel?
Choosing state and entity form	1–2 weeks	—
Finding and vetting the friendly clinician	2–8 weeks	Yes, with everything
Forming the PC	1–6 weeks (board pre-approval states are slower)	—
Forming the MSO	1–5 business days	Yes
Drafting and signing the agreement stack	3–8 weeks with counsel	Partially, starts after entities exist
NPIs (Type 1 and Type 2)	Days to ~2 weeks via NPPES	Yes
CAQH profile build and attestation	1–3 weeks	Yes
Bank account opening	5 minutes per entity on Lemma, approved within hours; 1–3 weeks per entity at a brick-and-mortar bank	Yes
Medicare enrollment (PECOS)	~60–120 days	Yes
Commercial payer credentialing	~90–180 days per payer	Yes, start them all at once
Medicaid enrollment	~60–180 days, state-dependent	Yes
EDI / ERA / EFT enrollment per payer	2–6 weeks after contract	Follows the contract
Selecting and implementing the billing stack	2–6 weeks	Yes

The critical path is: form the PC → get the Type 2 NPI → submit payer enrollments → wait. Everything else should be happening during the wait.

Start payer enrollment the day your PC has an EIN and a Type 2 NPI. Do not wait until you have hired staff, signed a lease, or picked an EHR. Every week of delay adds a week to the launch.

What it costs

Ranges for a single-state, single-location launch. These are directional, not quotes.

Item	Typical range
PC formation (filing + registered agent)	$200 – $1,500
MSO formation	$100 – $1,000
Healthcare regulatory counsel, full agreement stack	$10,000 – $40,000+
Fair market value study for the management fee	$5,000 – $25,000 (often deferred to first raise)
Malpractice insurance (per clinician, specialty-dependent)	$4,000 – $50,000+ / year
EHR/PM system	$300 – $900 / provider / month
Clearinghouse	Metered per transaction, or bundled into the EHR
Credentialing (outsourced, per provider per payer)	$150 – $400
Bookkeeping (two entities)	$500 – $2,500 / month

Counsel is the cost that most surprises founders. Do not use a generalist corporate lawyer or a template. An MSA that does not survive a CPOM challenge in your state is worse than no MSA, because it documents the arrangement that fails. See Hire healthcare counsel.

What can be parallelized

Run these three tracks simultaneously from week one:

Legal track, state selection, entity formation, agreement drafting.
Payer track, NPIs, CAQH, then enrollment applications the moment the PC exists. This track has the longest lead time and the least control.
Operations track, banking, EHR selection, clearinghouse, staffing, lease.

The only hard dependencies are: the PC must exist before you can get its Type 2 NPI; the Type 2 NPI and EIN must exist before payer enrollment; and payer contracts must be executed before EDI/ERA/EFT enrollment for that payer.

Doing this in the wrong order

The most common expensive mistake is seeing patients before enrollment completes. Claims for services rendered before your effective date are generally not payable, and a verbal promise of a retroactive effective date is not enforceable. Some payers backdate; many do not. If you must open before credentialing finishes, understand your options, and their compliance limits, first: see Handle credentialing delays and gaps.
