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 long pole is almost always payer credentialing, not anything you 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 genuinely 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 single 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 everyone forgets. 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: what actually takes how long

Set this expectation on day one, with yourself and with your investors. Credentialing is the long pole.

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	1–3 weeks per entity	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. Not after you’ve hired staff, signed a lease, or picked an EHR. Every week you delay is a week added to the end.

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

The number that surprises founders is counsel. Resist the temptation to use a generalist corporate lawyer or a template. An MSA that doesn’t survive a CPOM challenge in your state is worth less than no MSA, because it documents the problem. 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.

A note on 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 the retro-effective date you were promised verbally is not a contract. 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.
